General Information

Safety Information The Televic Wired Confidea Digital Conference &

Interpretation System is state of the art and has been

designed to meet quality. Nevertheless, the individual

components of the conference system can cause danger

for persons and material assets if

• the conference system is not used as intended,

• the conference system is set up by personnel not

familiar with the safety regulations,

• the conference system is converted or altered

incorrectly,

• the safety instructions are not observed.

Wired Confidea – the digital conference & Interpretation system

Overview If you require high-quality conference and interpretation

equipment to support the communication process, then

the Wired Confidea Digital Conference & Interpretation

System is the solution to your problem. The new Wired

Confidea Digital Conference & Interpretation System

exploits all the advantages of digital communications

technology and offers its users a series of important

features:

• decentralized, clear sound reproduction,

• a full Digital System,

• easy installation and total control,

• functional and extremely easy to operate delegate

units,

• audience interaction,

• advanced functionality,

• the possibility to be combined with an infrared

Language Distribution System.

The Wired Confidea Digital Conference &

Interpretation System is the perfect choice for both

small seminars and large international conferences.

An important feature of the Wired Confidea Digital

Conference & Interpretation System is its modular

design. Even when you change from a configuration for

small conferences to a larger configuration, you can

easily add additional conference units and a software

control program. Whatever the circumstances may be,

the system can:

10

• quickly be set up, since all conference units are

connected in series,

• easily be configured for any kind of room and any

kind of participants.

11

The components of the Wired Confidea Conference & Interpretation System

A Wired Confidea Digital Conference & Interpretation

System basic setup consists of the following

components:

• delegate units,

• interpreter units,

• a central unit,

• system cables,

• and if required, the software control suite for the

conference system.

12

The delegate units

The delegate units feature a built-in loudspeaker,

allowing the participant to directly hear all audio

information, e.g. speeches, presentations or any other

audio material. This loudspeaker system ensures

excellent sound quality at a comfortable volume

throughout the entire conference room.

The delegate unit’s electret microphone transmits every

word in excellent audio quality over the system. The red

signal ring on the microphone serves as an indicator of

who is currently occupying the floor (when the red light

is on).

In configurations with voting units, the conference

participants can participate in voting sessions.

The delegate units can range from the most basic units

to delegate units intended for a chairman with options

like voting, interpreter channel selection and an Oled

display. All the different delegate units will be

presented in the next chapter.

The units are connected in series. One cable string can

comprise up to 20 conference units. The 6 ports at the

back of the central unit can each connect a string of

delegate units. Up to 120 delegate units can thus be

connected to one central unit. And up to 1024 delegate

units can be set up through coupled central units.

All the different delegate units will be presented in the

next chapter.

Use of TCS2500 delegate units and flushmount combipanels in combination with Wired Confidea units

The TCS2500 delegate/chairman units and flushmount

combipanels can be used with Confidea CU .

Remark : It is NOT allowed to connect devices with

automatic input/output detection (like Wired Confidea

delegate units) and other devices without automatic

input/output detection ( like TCS2500 delegate units or

flushmount combipanels ) in the same branche !

13

The units are connected in series. One cable string can

comprise up to 20 conference units. The 6 ports at the

back of the central unit can each connect a string of

delegate units. Up to 120 delegate units can thus be

connected to one central unit. And up to 1024 delegate

units can be set up through coupled central units.

The interpreter unit

The interpreter unit has a similar design as a delegate

unit. Next to the quality microphone and the headphone

output it has three knobs for adjusting the volume,

treble and bass levels of the incoming speech.

The badge can contain all relevant information for each

interpreter so that each interpreter can transfer his

settings to a new interpreter unit.

An extended amount of functionality is made available

on the interpreter unit by the easy to use interface knobs

and buttons and the LCD display. Every aspect of this

functionality will be explained in the next chapter.

14

The CONFIDEA CU

The CONFIDEA CU is the core of the Wired Confidea

Digital Conference & Interpretation System and, at the

same time, serves as an interface for additional audio

systems.

During the conference, the central unit will manage the

speech of the delegate units and the interpreter units.

Via the central unit’s operating menu, the configuration

of the conference system can be altered to satisfy the

needs of the conference room and its users.

On the central unit, you can choose between 10

different conference modes, each with its own specific

characteristics. However, some of these operating

modes are only relevant in a system with the PC control

software.

The central unit manages the microphones, allows the

operating mode to be set, activates the microphone units

and manages the request-to-speak list.

The central unit has a built-in power supply unit for

powering up to 120 delegate and/or interpreter units and

is therefore more than sufficient to set up a basic

conference system. For larger conference systems,

additional central units can be interconnected.

The system cables

Power supply of the conference and interpreter units is

via the system cables which also transmit the digital

audio and status information.

15

The software control suite (optional)

A conference manager can control the entire conference

via a PC if he uses the optional software control suite.

The software control suite provides several extra

functions, next to the functionality provided by the

central unit:

• Additional functions for microphone management:

the conference manager can easily monitor which

delegates have made a request to speak, which

delegates are currently speaking, activate certain

microphones, etc. Two possibilities to manage the

microphones are supplied: the first is a schematic

view of the room and the delegates; the second is

through a list of names (nominative view).

• Display of voting results as diagrams: the results of

a voting can be represented graphically and can, for

example, be displayed in the conference room by

using a projector. Voting in combination with badge

verification is also possible.

• Interpreter management: the conference manager

can configure each desk in each booth.

Configuration includes assignment of languages to

interpreter units (both for the A and B channel),

operation modes, etc.

• Delegate database: the delegate database allows the

conference manager to specify delegate information.

This information can then be displayed in the

nominative and the schematic view of the

microphone management screens. It is also possible

to use the information contained on the badges.

• Multiple Chairmen units: the conference manager

can assign multiple chairmen units.

The technology used

Both the control and sound transmission of the Wired


are digital, resulting in excellent quality. The language

channels are transmitted over a 16 kHz bandwidth at a

16-bit resolution.

The delegate units are connected to each other and to

the central unit by means of system cables. The system

uses one digital speaker channel and a simultaneous

translation of 4/8/28 channels.

The components of the Wired Confidea Conference & Interpretation System

The components The components described on the following pages are

available for the Wired Confidea Digital Conference &

Interpretation System. Which of these components you

require depends on the desired size of the Wired

Confidea Digital Conference & Interpretation System.

The Wired Confidea ( Confidea-L) delegate units

6 different delegate and 4 chairman units are available

for the Wired Confidea Digital Conference &

Interpretation System. All versions of the delegate units

are equipped with varying levels of functionality. There

is also one type of interpreter unit available. The

delegate units differ from each other in the following

features:

• a priority button for the chairman versions of the

delegate units.

• An Oled display for channel selection and listening

level indication, and two digital UP/DOWN buttons

for language selection.

• 5 or 3 voting buttons .

• an Oled display for voting related information or

other relevant information.

These features are only available on certain delegate

units. We will present and explain each of these

delegate units. Next to the delegate units the interpreter

unit will also be presented and explained.

The CONFIDEA CU is able to serve conference

systems in a non-coupled environment with up to 120

units. For larger systems with a maximum of 1024

terminals, you can interconnect up to 40 central units

via the system cables. The CONFIDEA CU is an

integration of a microphone system and an interpreter

system.

The CONFIDEA CU’s menu control allows you to:

• set the conference system to one of the 10 different

operating modes (note however that some are only

relevant in an environment where there is a PC

connected to the central unit with the microphone

management software),

• set the delegate unit’s audio options like volume,

automatic gain reduction, low, middle and treble,

• configure the options of the microphone system and

the interpreter system,

• initialize the microphone and interpreter system,

• specify the auxiliary IN/OUT settings,

• reset the microphone and interpreter system,

• configure the language options of the interpreter

desks and booths,

• save the configuration for the interpreter system as

Config1 or as Config2,

23

• load the configuration for the interpreter system

from Config1 or from Config2,

• and more.

Via the two XLR-3F sockets (AUDIO IN 1 & 2) of the

central unit you can connect microphones with suitable

preamplifiers or you can feed audio signals from

additional audio equipment to the conference system.

The output signal of the floor speech is available on the

XLR-3M audio output (AUDIO OUT). Via the XLR-

3M audio output you can:

• connect a public address system and transmit the

audio signal of the floor speech via the public

address system,

• transmit the audio signal of the floor as “original

soundtrack” to a broadcasting station.

It is also possible to connect an infrared language

distribution system to the CONFIDEA CU, allowing

guests or participants who don’t have their own

conference unit to follow the conference via infrared

headphones. The guests or participants can also choose

between the floor channel and up to 28 additional

language channels.

You can also connect an analog output panel (AOP) to

the CONFIDEA CU. The purpose of the analog output

panel is to provide the system with additional analog

outputs. A total of 9 XLR-3M ports are available to

send an analog signal out to other devices, for example,

a recording device or a public address system.

A D-sub connector with 6 analog outputs is also present

on the central unit for analog outputs. The technical

specification of the connector is explained further in this

manual under “Connecting equipment to the AUX

OUT”.

Repeater for the system (*)

A repeater is used to strengthen the signal on a system

cable. When a system cable reaches a length of 80 m,

the signal over the system cables becomes too weak.

We can insert a repeater after the lengthy system cable

to strengthen this signal.

The repeater box has two ports, the IN and OUT port.

The RJ-45 OUT connector (1) should connect a cable

string with a delegate unit and the CONFIDEA CU

should be connected to the RJ-45 IN connector (2) of

the repeater.

The power supply (DC) which reaches the repeater is 30

@ 60 VDC straight from the central unit.

It is also allowed to attach a string of delegate units to

the CONFIDEA CU and then when a system cable

between two delegate units reaches 80 m to insert a

repeater. As you can see, the coloring of the RJ-45 ports

on the repeater is similar to the coloring of the RJ-45

ports of the delegate units. This makes connecting it to

delegate units quite straightforward.

(*) Important Remark :

Repeaters are devices without automatic input/output

detection , so may NOT be used in branches where

devices , with automatic input/output detection (like

Confidea-L units) , are used !

27

The LEDs of the repeater:

The repeater box has, next to the two RJ-45 connectors,

three LEDs:

• UPLINK FAIL: lights up when there is no

communication with a delegate unit.

• DOWNLINK FAIL: lights up when there is no

communication from the CONFIDEA CU.

• POWER SUPPLY: should always lights up,

whenever the repeater has power.

28

The system cables

The system cables required for the planned conference

system are included in the delivery if they were ordered.

These cables have RJ-45 shielded connectors. The

length of the system cables may range between 0.5 m

and 80m.

With these cables, you can:

• interconnect the delegate units,

• interconnect up to 40 central units for setting up

large conference systems,

• interconnect with an analog output panel.

Via the system cables you can connect the cable strings

with the delegate units to the CONFIDEA CU.

The following illustration specifies the requirements of

the system cables used within the Wired Confidea

Digital Conference & Interpretation System.

Structuring the Wired Confidea Digital Conference & Interpretation System

Expansion stages This chapter provides information about possible

conference room configurations. It will be explained by

using some example set-ups on how your conference

system can be structured. The components which are

required for the different expansion stages will also be

discussed.

Finally, this chapter also gives an overview of the

additional audio equipment that can be connected to the

conference system.

Possible expansion stages

Depending on the number of conference participants,

four different expansion stages are distinguished as

examples. These expansion stages will show you some

possible set-ups of the Wired Confidea Digital

Conference & Interpretation System. It is possible to set

up a diverse set of configurations depending on the

requirements of the user and the conference room.

These expansion stages should help you tackle any

problems while setting up a configuration.

• Expansion stage (1) comprising up to 20 terminals


with various kinds of terminals


In all the configurations, the conference terminals are

interconnected and powered via the system cables

30

which also transmit the digital audio and status

information.

Note:

In the following examples, the standard length of “3m”

is always given for the system cables between the

conference terminals. However, it is not a problem to

use other cable lengths or cables of differing length

within the same string of delegate units.

To make sure that all the delegate and interpretation

units are supplied with a sufficient voltage level, please

refer to the chapter “Determining the maximum cable

lengths”.

Expansion stage (1): up to 20 conference terminals

In small conference system configurations (expansion

stage 1), you can start with 20 conference terminals

connected to one CONFIDEA CU.

Note:

The number chosen here: 20 is only a sample number,

the real number of terminals depends on the

requirements of the user and the conference room.

Example 1:

The maximum distance between the central unit and the

first conference terminal or two conference terminals

may not exceed 80 m without a repeater. Normally the

length of the system cables between two conference

terminals is typically 2 or 3 m. If you interconnect the

maximum number of conference terminals in one string,

the length between the central unit and the first

conference terminal may not exceed 80 m without a

repeater. In the discussion of the expansion stages and

the examples, we will use a length of maximum 80 m

for the first system cable.

31

Note:

Next to these requirements the total length of the cable

string which connects all the terminals to the central

unit should not exceed a specific length. This length can

easily be calculated for your desired configuration. We

can provide you with a power calculator tool that can be

used to simplify the calculation of this length.

Up to 20 conference terminals can be interconnected in

one string. All 20 terminals can be powered via the

CONFIDEA CU’s integrated power supply unit.

Instead of interconnecting 20 terminals in one string

you can also split up the terminals into three different

strings:

Example 2:

The CONFIDEA CU’s integrated power supply can

power up to 120 terminal units which can be split up

into six different strings. In our expansion stage we only

have 20 terminal units which we will split up into four

different strings. Each of these strings will have 5

terminal units attached to it.

The distance between the CONFIDEA CU and the first

conference terminal of a string may vary, but the

maximum distance of 80m without a repeater may not

be exceeded. The length of the system cables between

two terminals is typically 2 or 3m.

Expansion stage (2): up to 120 terminals with various kinds of terminals

In conference system of expansion stage (2), up to 120

terminals can be connected to the CONFIDEA CU.

Example:

The maximum distance between the CONFIDEA CU

and the first terminal may not exceed 80m without a

repeater. The distance between the conference terminals

is typically 2 or 3m. Since the CONFIDEA CU’s

integrated power supply can only supply power for a

maximum of 120 conference terminals, it is discouraged

to attach more conference terminals. When you do

decide to attach more than 120 terminals to a central

unit, then a correct operation of the system cannot be

guaranteed.

Expansion stage (3): up to 600 terminals with various kinds of terminals

You can connect a maximum of six cable strings with

up to 120 terminals to one CONFIDEA CU. For larger

systems with up to 1024 terminals, you therefore

require a total of nine CONFIDEA CUs. One of these

central units is master. The additional CONFIDEA CUs

are connected as “slaves” to the central unit configured

as master. In an environment where the microphone and

conference system is controlled by a PC, the PC must

be connected to the “master” central unit.

In this expansion stage a total of four CONFIDEA CUs

are needed to control all the microphone and interpreter

33

units. You first have to interconnect all the cable strings

to the CONFIDEA CU. A maximum of 20 terminals

can be interconnected in one string, and a total of six

strings can be attached to the central unit. After

interconnecting all the strings and attaching all the

strings to the appropriate CONFIDEA CU we can begin

to interconnect the central units. How the central units

are interconnected is described in the topic

“Interconnecting multiple central units”.

The distance between a CONFIDEA CU and the first

conference terminal of a cable string may not exceed

80m without a repeater. The length of the cables to

interconnecting the central units should be kept as short

as possible and certainly not exceed 80m.

Determining maximum cable lengths

In the preceding examples, the standard length of “3 m”

is always given for the system cables between the

conference terminals. However it is no problem to use

cables of different lengths within the same string.

If you want to use longer cables, make sure that all the

conference and interpreter terminals – including the last

one in the string – are supplied with a voltage of at least

30V!

Calculating the voltage drop on the system cables

Every meter of cable and every conference terminal in a

string causes a voltage drop. Thus the further back a

conference unit is located in a string, the less voltage it

receives. We have constructed a power calculation tool

to automate the calculation of the lengths of these

strings. The sheet is an easy method to calculate the

voltage drops on the individual sections of a sting. This

way, you know before setting up the conference and

interpreter system whether the system will function

correctly or not.

35

Additional equipment for your conference system

Connecting external audio sources

Via the XLR-3F socket of the CONFIDEA CU, external

audio sources which output a balanced mono signal can

be connected to the conference system. External audio

sources are, for example:

• wired microphones,

• wireless microphones,

• the audio channel of a video,

• a CD player,

• etc.

Transmitting a channel to broadcasting and TV stations

Important conferences and specialist congresses are of

great interest to the public. The Wired Confidea Digital

Conference & Interpretation System therefore allows

you to either transmit the floor speech via the XLR-3M

or SUB-D audio output (AUDIO OUT 1). On the

AUDIO OUT 2-3-4-5-6 you can output up to five

interpreter channels/speeches of your choice.

With an AOP2500 Analog Output Panel system you can

output more channels for recording or broadcasting via

the additional XLR-3M ports on the AOP2500.

Transmitting a channel to a Public Address system

Via the central unit’s (or the AOP2500) XLR-3M audio

output, you can connect a PA system to which the floor

speech/channel can be transmitted. This public address

system can then broadcast the sound in e.g. the foyer or

another room.

You can connect the control of an infrared transmitter,

allowing guests or participants who don’t have their

own conference terminal to participate in the conference

via infrared headphones. These guests or participants

can then choose between the floor speech/channel and

the interpretation channels.

Setting up the conference system

Installing and interconnecting This chapter provides information on how to set up the

Wired Confidea Digital Conference & Interpretation

System.

Preparing the Wired Confidea Digital Conference & Interpretation System components for set up

Conference and interpretation units

The conference and interpretation units are “factory-

prepared” to allow immediate use, i.e. after unpacking a

unit, you simply have to plug it into a central unit and

initialize the microphone.

Central unit

• Connect the mains cable to the appropriate

socket (21).

• Connect the mains cable to the mains (100-240

V, 50-60 Hz).

Rack-mounting the system components

For larger conference systems, we recommend

mounting the system components into a rack.

Interconnecting the components of the conference system

Depending on the expansion stage of your conference

system, you have to:

• interconnect the conference terminals (all expansion

stages),

• interconnect the central units,

• connect a PC to the “master” central unit if the

system is to be PC controlled (PC control optional).

Interconnecting the conference units

The conference units are interconnected via the RJ-45

shielded connectors on the back of the conference units.

The IN connector is colored grey and the out connector

is colored black. The system cables have a grey and a

black connector to guide you during the interconnection

of the terminals.

Free Input/Output connectivity in a specific branche is

only possible when only Wired Confidea units (=

Confidea-L) are used in that branch . When TCS2500

delegate or flushmount combipanels are used in the

same branch as Confidea-L units , then Input/output

connectivity of TCS2500 and Combipanels must still be

respected!

Connecting a cable string to the central unit

After having interconnected the conference units, you

have to connect these strings to the CONFIDEA CU.

You can connect up to six cable strings to one central

unit.

• Connect the cable string to one of the RJ-45

shielded connector sockets labeled: PORT 1, 2, 3, 4,

5 or 6.

• When the length of the cable to the first conference

unit, or when the length of the cable between

conference units is 80m; then a repeater should be

placed between the central unit and that delegate

unit or between the two delegate units.

• To see additional information about the repeater and

how to connect the repeater to the central unit and a

delegate unit and/or between two delegate units see

the paragraph on: ‘Repeater for the system’.

Interconnecting central units

Chain topology

The best approach is to mount the central units into a

rack. In the chain topology we interconnect the

CONFIDEA CUs via the RJ-45 shielded connector

sockets (SLAVE IN, SLAVE OUT and MASTER

OUT) at their rear. The CONFIDEA CU which is

master has an FTP-CAT5 cable connected to the

MASTER OUT port. The SLAVE IN and SLAVE OUT

ports are then used for the central units which are slave.

• At the first CONFIDEA CU, connect the end of

the system cable to the MASTER OUT socket.

This central unit is now master.

• Connect the other end of the system cable

(coming from the master unit) to the SLAVE IN

socket of a second CONFIDEA CU.

• For multiple slaves, connect the SLAVE OUT

from the first slave to the SLAVE IN from the

next slave.

• Configure the slave central units so that the

master-slave symbol ( ) is displayed on the

main menu item. Please refer to the explanation

for the main screen for more details on this

symbol.

Star topology

When the conference room has a high number of

coupled central units, it might be better to use a star

topology. In this topology we interconnect the slave

CONFIDEA CUs via the RJ-45 shielded connector

sockets (SLAVE IN) at their rear with the master

central unit via the connector sockets (MASTER OUT,

SLAVE OUT or PORT 1-6) or with a slave central unit

via the connector sockets (MASTER OUT, SLAVE

OUT or PORT 1-6). The CONFIDEA CU which is

master has an FTP-CAT5 cable connected to the

MASTER OUT port or/and a cable connected to PORT

1-6 or SLAVE OUT. The SLAVE IN port are then used

for the central units which are slave. If necessary the

MASTER OUT, SLAVE OUT port or PORT 1-6 of the

slave central units can also be used to further extend the

star topology

• At the first CONFIDEA CU, connect the end of

the system cable to the MASTER OUT, SLAVE

OUT or PORT 1-6 socket. The central unit will

be master as long as no cable is inserted in the

SLAVE IN port of the central unit.

• Connect the other end of the system cables

(coming from the master unit) to the SLAVE IN

socket of the slave CONFIDEA CUs.

• For large star topologies, connect a system cable

between the SLAVE IN port of a central unit

and a SLAVE OUT, MASTER OUT or PORT

1-6 of another slave central unit

• Configure the slave central units so that the

master-slave symbol ( ) is displayed on the

main menu item. Please refer to the explanation

for the main screen for more details on this

symbol.

General

Briefly: A CONFIDEA CU is able to go into slave

mode if the master-slave symbol is visual ( ). A

slave CONFIDEA CU is identified by a connection on

its SLAVE IN port and the slave symbol ( ).

If the SLAVE IN port is not connected then it is

automatically a master central unit ( ). The output

port that connects with the SLAVE IN port can be the

SLAVE OUT or the MASTER OUT port or one of the

6 digital bus ports. Typically the MASTER OUT and

the SLAVE OUT will be used for coupling, but in an

alternative configuration you can use them to add extra

conference units with an external power supply.

The startup sequence of the central units is randomly.

Do keep in mind that the startup of the central units, in a

41

coupled environment, can take a considerable amount of

time. All the units connected to all central units in the

configuration have to be processed. The central unit will

react slower to user input during this phase. Once the

system is fully initialized, everything will react

normally. This initialization time is dependent on your

configuration. The basic principle applied here is: the

larger the configuration, the longer the initialization

time.

The CONFIDEA CU which is master can be used to

configure all settings. The other CONFIDEA CUs

which are slave are locked and will display the locking

symbol ( ) in the lower right corner of the screen of

the CONFIDEA CU. You cannot alter any settings on a

slave central unit. Go back to master mode, by pressing

the F2 button for 3 seconds, if any settings need to be

altered.

42

Connecting additional equipment

Connecting headphones to a conference unit

• Connect headphones to the 3.5 mm mono jack

socket.

• First, use the level control to reduce the headphone

volume to the minimum.

• Slowly set the volume to a medium level.

When people use headphones, they tend to choose a

higher volume than with loudspeakers. Listening at high

volume levels for long periods can lead to permanent

hearing deficiency. Please protect your hearing!

Connecting the analog output panel

You can connect an analog output panel (AOP2500) to

the central unit for audio output. The DATA OUT

socket on the CONFIDEA CU should be connected to

the DIGITAL IN socket of the AOP2500.

Connecting an external audio source

You can connect external audio sources such as wired

microphones, wireless microphone systems, the audio

channel of a video recorder, a CD player, another

conference unit for remote conferencing, etc. to the

conference system. The audio sources to be connected

must deliver a balanced mono signal at the XLR-3F

socket (8). Depending on the strength of the audio

signal, you can increase the input sensitivity of the

conference system in the central unit’s operating menu.

Connect the audio sources as follows:

• Connect the audio source to one of the XLR-3F

sockets of the central unit.

• If necessary, adapt the input sensitivity in the

operating menu.

The aux out numbers described in the above illustration

relate to aux out 1 - 2 – 3 – 4 – 5 – 6 in the menu of the

CONFIDEA CU. For example: if you change the

channel assigned to aux out 3 on the central unit, then

these changes will be noticed on the 3-11 pin

combination.

The floor speech/ channel signal is transmitted on aux

out 1. This channel cannot be changed. The floor

speech/channel signal is also transmitted on the XLR-

44

3M socket. The volume difference between AUX OUT

1 on the SUB-D 15 connector and the AUX OUT 1 on

the XLR socket can be adjusted by changing the

Volume XLR in the AUX OUT 1 menu item. By

default there is no difference.

It is however possible to alter the channel signal for the

remaining auxiliary outputs. You may assign any

interpreter channel or the floor channel to these outputs.

Next to the channel you can alter the volume and the

status (ON/OFF) of an auxiliary output.

The volume difference between AUX OUT 6 on the

SUB-D 15 connector and the AUX OUT on the

headphone jack can be adjusted by changing the Vol.

Headphone in the AUX OUT 6 menu item. By default

there is no difference.

Connecting the PC to the central unit

The PC software consists out of two different parts. The

two distinguishable parts are the microphone

management software (TMS2500) and the interpreter

management software (TIS2500). To connect the PC to

the CONFIDEA CU, when you installed both the

microphone and interpreter management software, you

need two serial ports on your PC. One serial port is

necessary for the conference management software and

the other port is necessary for the interpreter

management software. The COM ports of the central

unit work at a speed of 19200 bits per second.

The port on the back of the CONFIDEA CU labeled

COM 1 is the port associated with the interpreter

management system (TIS2500).

The port on the back of the CONFIDEA CU labeled

COM 3 is the port associated with the microphone

management system (TMS2500).

Note that the software versions will be checked at both

sides before starting the communication. The PC will

check if the CU version is compatible with the PC

software version and the central unit will check if

remote control is allowed by the pc that asks the

connection.

45

The cables necessary to connect the central unit to the

PC are described below.

The diagram of the cable described above is actually a

null-modem cable. This means that a standard null-

modem cable without handschaking can be used to

connect the PC with the central unit ,

Remark : NO hardware handshaking is allowed

(check comport settings)!

46

Turning the central unit on and off

When turning on the power of the conference and

interpretation system, it is important that the

components are turned on in the correct order.

In conference systems with several central units, first

turn on the “master” central unit. Then turn on the slave

units in the sequence they are connected to the master

unit. Please keep in mind that it takes a certain amount

of time until the system has fully started up. The larger

the configuration, the longer it takes to start the system.

During this phase, the menu will react slower to user

input. Once all units are initialized and the system has

started up, the master central unit will react normally

again.

Turning the central unit on

Set the POWER switch (22) in the ON position.

The conference and interpretation units which are

connected to the central unit are now ready for

operation.

The start display appears on the LCD display of the

central unit.

Volume =

P1 P2 P3 P4 P5 P6 Figure 2 - The start-up screen of the central unit

Turning the central unit off

Set the POWER switch (22) in the OFF position.

The conference and interpretation units are now

disconnected from the voltage supply. Switch off the

central units in a coupled configuration starting with the

slaves. Finally switch off the master central unit.

Configuring the conference system

Overview This chapter provides instructions on how to:

• operate the Wired Confidea operating menu,

• initialize the microphone system,

• set the operating microphone mode,

• adjust the audio settings for the loudspeaker,

• activate and configure the auxiliary inputs and

outputs,

• resetting the microphone system,

• access the microphone options,

• configure the interpreter system,

• choose the language options for the different booths.

48

Introduction to the CONFIDEA CU’s operating menu

The startup display

After turning on the central unit, the start display

appears, showing the Wired Confidea Digital

Conference & Interpretation System main menu where

you can choose between six menu choices:

• Conference: contains the configuration of the

microphone system and the delegate units.

• Interpreter: contains the configuration of the

interpreter system and the interpreter booths.

• AUX-OUT/IN: contains the configuration of the

auxiliary outputs and inputs.

• System: contains system wide configuration options

• Language: contains the language configuration of

the CONFIDEA CU’s menu.

• License: contains all license related information and

configuration options.

After approximately one minute the menu will jump to

the volume setting of the delegate loudspeaker. This

happens because the volume setting is accessed most

frequently when using the Wired Confidea Digital

Conference & Interpretation System.

The lock functionality

It is possible to lock the menu of the central unit.

Suppose that you configured the central unit to your

desires and you do not want anyone to alter these

settings. To do this, you have to lock the main screen of

the central unit. This is the screen where you can see the

volume bar.

Navigate to the main menu of the central unit. The

menu can now be locked by pressing the F1 and the F3

button at the same time and keep them pushed for about

two seconds. After you released the buttons the locking

symbol ( ) will be displayed in the lower right corner

of the screen of the central unit. When you try to access

the menu of the central unit by pressing the ENTER

button, nothing will happen. This means that you are

successfully locked out of the menu.

The menu can be unlocked again by the operator

whenever he wants to alter some settings. The sequence

to unlock the menu is the same as the sequence to lock

49

the menu. Press the F1 and the F3 button at the same

time again for about two seconds to unlock the menu.

When the buttons are released the locking symbol ( )

will disappear from the lower right corner of the main

menu.

Note: The locking symbol also appears on certain

central units in a coupled environment. Specifically,

they appear on the slave central units. You can

distinguish a slave central unit from a locked central

unit by the volume bar. A slave central unit has no

volume bar.

The menu buttons

The wheel, ENTER and EXIT button allow you to

navigate through the operating menu.

The menu - explained

Working with the root menu

The main screen

The main screen contains two important elements. The

first is a volume bar which can be altered using the

wheel. During a conference the volume can be set lower

or higher when necessary. The second element is an

indication of the ports. These indicate which ports are

used and to which port a string of conference terminals

is connected. More of this is explained in the section

discussing the system diagnostics.

Two central units can also be coupled to establish a

bigger conference room, controlled by a single, the

master, central unit. More on this coupling can be found

elsewhere in this manual. To indicate that a central unit

is able to work as a slave central unit a sign has been

put in the top right corner on the menu display. If this

symbol is not visible, try to press the F2 for about 3

seconds. If the symbol doesn’t appear, it means you

have a restricted license. When the symbol is visible

and the central unit has detected a master central unit on

the slave port, the central unit will automatically go into

slave mode, the slave symbol will be adjusted like

shown in the picture on the left.

In summary the table below explains the slave symbol.

(NO SYMBOL)

When a central unit is in slave mode, but some settings

need to be altered like the output channels on the

different analog outputs, you can always go back to the

master mode by again pressing the F2 button for about

3 seconds.

79

The conference menu - overview

Default values of the microphone system

1 Conference

A number of default values will be loaded into the

System the first time the CONFIDEA CU boots. These

default values ensure a correct operation of the

CONFIDEA CU conference system. However, all

delegate units connected to the central unit will display

an Init Refused screen. This means the delegate units are

not known to the conference system. We should

therefore start with the initialization of the microphone

system.

NOTE : an overview of the default values can be found

in appendix D

Initializing the microphone system

The first time you start using the Wired Confidea

Digital Conference & Interpretation System in a new

set-up you have to begin with an initialization. The

initialization can take place in two different ways. You

have the choice between an automatic initialization and

a manual initialization. Both options have their

advantages and disadvantages, which we will pinpoint

in a moment.

The automatic initialization is very useful when you

want to initialize the conference units without

initializing each conference unit separately. When you

enter the automatic initialization menu, then the

conference units will have initialized themselves. You

will be informed to wait a little. After pressing the

ENTER button the units will be initialized.

If the order in which the conference units are initialized

is important, then you are advised to use the manual

init. When the manual initialization is active, then the

red signal ring of all the conference units will begin to

flash. Notice that only the delegate units will begin to

flash and not the interpreter units! The interpreter units

do not respond to an initialization of the conference

menu because these are managed by the interpreter

subsystem. Pressing the microphone button on the

conference units will signal the central unit that the

Conference

7 Initialise Units

Initialise Units

2 Automatic Init

Manual Init

1 Full Init

Full Init

Press ENTER to Save

80

microphone is initialized. If the microphone is accepted

by the central unit, then the red signal ring will stop

flashing. You can now initialize the conference units in

the order you desire.

In case you already have a room configuration set up

which you want to keep, and you want to add a new

unit, then you can opt for the Add Unit menu item.

When the menu item is activated, then the red signal

ring of all unknown conference units start to flash. The

new units may now be initialized by pressing the

microphone button.

In case you want to delete a conference unit from the

configuration, you have to select the microphone

number on the central unit in the Delete Unit menu

item. Once you have selected the appropriate number

and pressed the ENTER button, then you can safely

remove the conference unit.

In case you want to reserve a conference unit you have

to select the microphone number on the central unit in

the Reserve Unit menu item. Reserving a microphone is

useful when you have a room in expansion. Maybe

some place to put e.g. microphone 17 is foreseen in the

future but cannot be set up right now. In this case you

can reserve the microphone for later. The sequence in

which a microphone is reserved is somewhat special

though. To reserve a microphone, you should first enter

the Manual Init – Full Init menu item. Start the full init

and exit the menu item. Then browse to the Reserve

Unit menu item and enter the numbers of the conference

units you want to reserve. After these unit numbers have

been entered, you can start pushing the microphone

numbers of the conference units.

Suppose now that you reserved conference unit number

7 and you have come at a moment when you want to

add conference unit 7 to the configuration. The first

thing you have to do know is activate the Delete Unit

menu item to delete the reserved number from the

conference configuration. Once the unit number has

been deleted, you have to activate the Add Unit menu

item, and press the newly added conference unit. It will

have been initialized with the previously reserved

number.

Note: When you enter the Manual Init – Full Init menu

item, then all data about previously reserved numbers

will be lost.

Choosing the conference mode

By selecting a certain conference mode, you can

strongly influence the character of a discussion:

• you can determine the level of control of the

chairman,

• and you can determine whether the conference

participants can take the floor immediately or if they

have to “apply” for the floor.

Note: A chairman unit is always able to speak! No

matter what mode the conference system is in, the

chairman is always able to speak by pressing his

MICRO button. The chairman can also deactivate all

active conference units by pressing his PRIOR button or

activate the delegate unit that requested to speak by

pressing the NEXT button.

Note: Multiple chairmen units can also be assigned by

using the PC software or by using appropriate menu

item.

You have the choice between 10 different operating

modes. The operating mode is selected in the Operating

Mode menu item. Note however that one mode is only

useful in combination with a PC installed with the

software control suite. This mode is: No request.

Without a PC you can use the With request, With

request – no clear, Direct Access, FIFO, Group 1-4 and

override. With a PC and the software control suite all

the operating modes can be used.

Operating modes:

• No request: the participant willing to speak has to

notify the conference manager that he is willing to

speak. He can do this by raising his hand or any

other means not involving the microphone. Once the

conference manager has noticed that a participant

has requested the floor, he can activate microphone

of the participant or ignore his request. The

conference operator has total control over the

microphones.

• With request: enables the participant to send a

request to the chairman or conference operator by

pressing the microphone button (or to cancel his

request by pressing the microphone button again).

Once the floor is requested, the green LED above

the microphone button will flash. This means that

the conference unit is in request mode. The

Conference

chairman or conference operator grants the

participant the permission to talk by using the NEXT

button or by clicking the green microphone on the

computer screen. While the conference unit is in

request, the red signal ring of the microphone will

flash if this option is selected.

• With request no clear: enables the participant to

send a request to the conference operator. However,

he cannot cancel his request. The chairman or

conference operator grants the participant the

permission to talk by using the NEXT button or by

clicking the green microphone on the computer

screen. During the in request period, the red signal

ring of the microphone will flash if this option is

selected.

• Direct Access: enables the participant to turn on his

microphone at any time. The only limitation here is

the maximum number of microphones which may

be active simultaneously.

• FIFO: enables one microphone at a time to be active

without intervention of the conference operator.

Activation of a new microphone overrides the

current active microphone. The only exception here

is that the microphones of a delegate and the

chairman can be active at the same time.

• Group 1: enables one microphone at a time to be

active without a request for activation. Other

participants may put their microphone in request

mode; the first applicant gets the floor when the

delegate who has the floor turns off his active

microphone or when the chairman or conference

operator grants the participant the permission to talk

by using the NEXT button or by clicking the green

microphone on the computer screen.

• Group 2: enables two microphones to be active at

the same time. Other participants may put their

microphone in request mode; the first applicant who

requested the floor gets the floor when one of the

currently active microphones is turned off or when

the chairman or conference operator grants the

participant the permission to talk.

• Group 3: works exactly like Group 1 and Group 2,

with the alteration that three participants can have

the floor at the same time.

• Group 4: works exactly like Group 1 and Group 2,

with the alteration that four participants can have the

floor at the same time.

83

• Override: works like the FIFO mode, with the

alteration that “MAX # Microphones” participants

can have the floor at the same time. Activation of a

new microphone will overrides the microphone that

was active for the longest time if the total number of

active microphones would exceed the user defined

“MAX # Microphones”. Here we have also the

exception that Chairmen units can always be

activated.

Max number of microphones simultaneously active

In the operating mode No request, With request, With

request – No Clear and Direct Access the maximum

number of microphones which may be active is

relevant. This number can be set in the Microphone

Limit menu item. The range of this value is between 1

and 15.

Adjusting the audio settings for the loudspeaker

By selecting the Loudspeaker menu item you can alter

the audio settings of the conference unit’s loudspeakers.

It is possible to adjust the volume, the low, the middle

and the treble audio settings. The volume can also be

adjusted when the menu jumps back to main menu.

Turning the wheel button will automatically change the

volume. If you choose to save the settings, then these

settings will be stored in the central unit so that the next

time the system boots these settings will become active

automatically.

Adjusting the audio settings for the microphone

By selecting the Microphones menu item you can alter

the audio settings of the conference unit’s microphone.

It is possible to adjust the automatic gain reduction, the

low, the middle and the treble audio settings. The

limiter gain of the microphone can also be set. Turning

the wheel button will automatically change the audio

setting. The automatic gain reduction indicates how

much the gain will be reduced when multiple

microphones become active. The higher the number, the

higher the reduction will be for multiple microphones.

If you choose to save the settings, then these settings

will be stored in the central unit so that the next time the

system boots these settings will become active

automatically.

The following graphic shows the automatic gain

reduction in function of the number of microphones that

are activated. The gain reduction is indicated in decibel

and referenced to the gain for one active microphone.

Each graph indicates an automatic gain reduction

number that can be set on the central unit. Note that

although the maximum number of microphones is 15,

the curves stop at 9. When more than 9 microphones are

activated the gain reduction will be kept constant.

It is possible to adjust the limiter gain curve for the

microphones by setting the desired offset value in dB.

This is especially used to determine the reach for the

microphones. So it is possible to exclude the noise in a

room from amplifying. In a room with much noise only

the speakers’ voice will be amplified and not the noise.

Lowering the limiter gain will result in a shorter reach,

otherwise stated: only the sound of sources close to the

microphone will be amplified.

Configuring the chairmen

Multiple chairmen units can be assigned in the

Chairmen menu item. By default, during initialization,

only one chairman unit will be assigned. One can

assign up to 50 chairmen units for a single conference

configuration. The picture below shows how to assign

multiple chairmen units:

• By entering the Set Chairmen menu item, a

chairman index number can be selected. Note

that the first two digits are marked. The first two

digits represent the chairmen index number in

the range from 1 to 50 because 50 chairmen

units can be assigned. We start with the first one

so we scroll to number 1 by using the wheel

button. After the correct index number has been

reached, press the ENTER button.

possible to assign another chairman unit.

• If more chairmen units are desired, repeat the

same steps but now with a different chairmen

index number.

The chairmen list can be cleared by entering the Clear

Chairmen menu item and hitting the ENTER button.

NOTE 1: When the conference room is controlled by a

PC, the local chairmen settings will be overwritten by

the PC settings.

NOTE 2: When the delegate units are reinitialized, the

chairman settings are cleared.

Resetting the microphone system

If for any reason the system has to be reset, you can do

this in the Reset menu item. Only the microphone

system will shut down and start up again immediately.

This will not affect the interpreter system.

Accessing the microphone options

The microphone options are the Options menu item.

The menu item contains a number of menu items which

allows the conference system to be checked and to

adjust some general settings. Two test modes can check

the sound of the delegate loudspeakers and can check

which microphones are connected to and initialized by

the CONFIDEA CU.

The Test Tone is used to generate a test tone on all

loudspeakers of all delegate units. The Test Units option

will activate the micro of all delegate units one by one

in the sequence they were initialized. Once the test

The Test Tone comes in useful when you are testing the

loudspeakers of the delegate units. Activate the Test

Tone option whenever you are not sure that the

loudspeaker of a delegate unit is working correctly. The

Test Units option is useful when you initialized the

delegate units and you want to test if there were all

initialized correctly. The delegate units will only

activate when they are known to the system.

The third item in the Options menu allows you to set the

behavior of the red signal ring on a delegate unit during

request. You can choose to let the signal ring blink

along with the green request led or you can choose to

only let the green request led blink on the unit in

The conference menu - example Suppose the following circumstances apply: a Wired


needs to be set up in a conference room in which a

meeting with 10 participants will occur. One of these

participants is a chairman and the participants will have

to vote during the conference. We will need up to 10

conference units for our system of which one

conference unit is a chairman unit.

To be able to configure this configuration we would

need for instance the following hardware: one

CONFIDEA CU, one Confidea_L CV and nine

Confidea-L DV units.

Let’s start setting up the system starting from a default

configuration. The setup will be described one step at a

time to make it easier to understand. If you feel that the

discussion of the setup is too detailed, feel free to skip

this section.

The starting point of the steps that needs to be taken is

the main screen of the central unit unless noted

otherwise.

Loading the default settings

Start by loading the default setting for the conference

desks. We start from the main menu.

• Press ENTER, choose Conference. Press ENTER

again, now choose Initialize units. Press ENTER.

Now choose Load Defaults, press ENTER. Press

ENTER again to load the default values.

• To go back to the main menu, repeatedly press the

EXIT button until you reach the main menu.

• Now that the default values have been loaded; we

need to reboot the system. Start from the main menu

again. Press ENTER, choose Conference. Press

ENTER again, now choose Reset. Press ENTER

again to reset the conference system. Now go back

to the main menu.

Select the operating mode

We want to select our mode of operation. The

differences between the different modes of operation

are explained above.


again, now choose Operating Mode and press

89

ENTER. Select the operating mode and press

ENTER to save the operating mode.

Changing the delegate loudspeaker settings

The audio settings of the delegate loudspeaker can be

changed if for instance the volume settings of the

delegate loudspeakers are too low.

The volume setting of the loudspeakers of the

conference units can easily be changed in the main

menu by turning the wheel. The setting isn’t saved

however. If you want to save the setting you must go

through the following sequence of steps.


again, now choose Loudspeaker. Press ENTER and

choose Volume. Press ENTER and turn the wheel to

set the volume to the desired value. Press ENTER to

save the adjusted volume level.

• If you want to change the Low, Middle or Treble

settings, go through the same sequence as described

above and select the Low, Treble or Middle menu

option. Save your settings and exit the menu.

Changing the delegate microphone settings

The audio settings of the delegate microphone can be

changed if for instance the gain is to high when multiple

microphones are activated.

The automatic gain reduction setting of the conference

units can be changed by following the next sequence of

steps.


again, now choose Microphones. Press ENTER and

choose Auto Gain Redu.. Press ENTER and turn the

wheel to set the gain reduction to the desired value.

Press ENTER to save the adjusted gain reduction

level.

• If you want to change the Low, Middle or Treble

settings, go through the same sequence as described

above and select the Low, Treble or Middle menu

option. Save your settings and exit the menu.

Changing the maximum number of microphones which may be active simultaneously

Press ENTER, choose Conference. Press ENTER again,

now choose Microphone Limit. Press ENTER. Turn the

90

wheel to alter the maximum number of microphones.

Press ENTER to save your settings.

Initializing the conference units

There are 2 options during the initialization, an

automatic and a manual initialization. In most of the

cases an automatic initialization will suffice. The

manual initialization is most handy when you want the

delegate units numbered in a desired sequence.

The automatic initialization is self-explanatory; to

initiate it, execute the following sequence.


again, now choose Initialize Units. Press ENTER,

choose Automatic Init. Press ENTER. Wait until the

menu displays “Press ENTER to save

initialization”, then press ENTER.

• The manual init consists out of four parts. We have

a Full Init, an Add Unit, a Reserve Unit and a Delete

Unit menu choice. The purpose of these menu

choices has been explained above. The steps which

need to be taken are similar to the example given

below.

• To manually initialize the conference units execute

the following sequence: Press ENTER, choose

Conference. Press ENTER again, now choose

Initialize Units. Press ENTER, choose Manual Init.

Press ENTER and choose Full Init. Press ENTER.

The red signal rings of the conference units will

start flashing. Press the MICRO button of the

conference units in any sequence you desire. After

pressing the MICRO button the red signal ring stops

flashing, this means that the conference unit is

initialized.

• Go back to the CONFIDEA CU and press the

ENTER button to save the configuration.

• Congratulations, the system has been initialized.

To add a conference unit, execute the Add Unit menu

option. The red signal ring of the new conference units

will start flashing. Press its MICRO button to initialize

it.

When you want to delete a conference unit from the

current configuration execute the Delete Unit menu

option.

91

• Select the number of the microphone you want to

delete. Press ENTER to delete the microphone.

The Reserve Unit menu option has been explained

above as well as the steps to take.

Let the red signal ring blink in request mode

To let the red signal ring blink along with the green

request led above the microphone button follow the next

procedure.

Press ENTER, choose Conference. Press ENTER again,

now choose Options. Press ENTER and choose Light

Ring. Press ENTER and turn the wheel to set the light

ring in Blink at Request mode. Press ENTER to save this

setting.

Working with delegate conference units

Talking: The most important button on a conference

unit is the MICRO button. The MICRO button is used to

speak or to issue a request-to-speak. When you have to

request the floor to take the word, you need to press the

MICRO button. The green LED above the MICRO

button will then begin to flash along with the red signal

ring if this option is chosen. The chairman unit or a

conference manager which has a PC with the

microphone management software installed is able to

grant you access to the floor. Once you have been

granted the floor the red signal ring will light up.

Translations: To listen to the translated floor channel

you must have a conference unit with a channel

selector. To change the channel, press the up and down

buttons above and below the channel selector. You will

then hear the translation of the floor channel in your

headset.

Voting: You can only vote when the voting session has

been started by the chairman. For this you need delegate

units with voting possibility. Once the voting session

has started, you will notice that you have a choice for

your vote. These screens are depicted on the left. To

vote press the button under the value of the vote you

want to cast. The vote will then be registered. Once the

voting session is over, the results will be shown on the

display.

92

Working with chairman conference units

Priority: The chairman unit works in the same way as

the delegate unit, but has three extra options. The first

extra option is the PRIOR button. The prior button can

be used in two ways. It can be used to mute all currently

active delegate microphones or is can be used to

deactivate all of the active delegate microphones.

All the active microphones of the delegates will be

deactivated when you press the PRIOR button and

release it quickly. Just tapping the PRIOR button will do

just that.

By keeping the PRIOR button pressed down, you can

mute all active delegate microphones. When you release

the PRIOR button, then all muted delegate microphones

will become active again. All requests for the floor are

ignored while all delegate microphones are muted. Once

the PRIOR button is released, the conference can

proceed again in its normal operation

Voting: The second option is the possibility to start the

voting. However, voting is only possible with units

which have voting possibility. The display menu on the

chairman’s unit can be chosen by pressing the PLAY or

STOP buttons. At startup the screen of the chairman

unit looks like the figure depicted on the left. Note

however that when the conference room is controlled

with a PC the chairman units can no longer start a vote

session as this can be done using the conference

software.

Next request: The third option is to grant a delegate unit

access to the floor if he requested the floor to take the

word. On the Confidea-L CD , CV and CIV the NEXT

button is used to grant the floor to the first in request .

93

The interpreter menu - overview Next to the conferencing functionalities of the Wired


we have an interpreter system. The interpreter system

works closely with the interpreter desk units (ID2500),

so you have to have access to these units when you

want to use the interpreter system.

Usage

We will explain how the interpreter system is used with

an example. Let’s suppose we are in a conference room

where three different languages are spoken and where

the participants of the conference do not understand a

language different from their native tongue. The three

spoken languages are English, French and German.

Let us now suppose that six interpreters are at out

disposal and that we have six interpreter units for the

interpreters to use.

The interpreter unit may be mixed with the normal

conference units on a string or they may all be on the

same string. The good way to set up the interpreter

terminals is to divide them in three separate booths.

Three booths are set up with, in each booth, two desks.

We allow the interpreters to relieve each other by

setting up two desks in a booth. The booth and desk

number is configured on the interpreter desk (ID2500

unit) while you are in the initialization mode.

The first booth is assigned to the English language, this

means that its A channel is assigned to ENG. The

second booth is assigned the French language, so its A

channel is assigned to FRE and the third booth is

assigned to the German language so its A channel will

be GER.

Next to the A channel there is also a B channel. The B

channel of each booth and therefore each desk can have

another language assigned to it. This language depends

on the preferences of the interpreter as he can choose

his desired language.

If the interpreter knows more than one language, i.e. the

interpreter understands ands speaks English, German

and French; then he’ll be able to translate to each of

these languages. This means that even though the A

94

channel of a booth is fixed to a specific language, he

will be able to translate to the other languages on the B

channel.

Configuration

The Configuration menu allows you to make a

completely new configuration, alter the settings for the

current configuration or load a previous made

configuration. In the new and current menu you can

select a booth and alter the settings for that booth. The

settings that can be altered are the Language, the Auto-

floor and the B-channel. When you alter the settings of

a booth you have to remember to save the settings for

each booth. At the end of a configuration you can

choose to save the interpretation configuration as

Config1 or Config2. Not saving the settings or exit at

the end leaves the current configuration unchanged even

when you began a new configuration.

New Configuration

When you begin with a new configuration, by pressing

the enter button, the previous settings in the interpreter

system will be cleared. The settings for each booth can

now be configured.

NOTE: Don’t forget to save the configuration as

Config1 or Config2 after you altered and saved the

settings for each booth.

It is recommended to change the parameters in the

option menu, if necessary, after you made and saved a

new configuration.

Current Configuration

Entering the current menu you can make corrections on

the current configuration without deleting the settings

for each booth made previously. You will be able to

adjust the settings like explained below.

Saving Configuration

After altering the language settings for each booth,

starting from a new configuration or continuing with the

current one you will be asked to save the configuration.

You can choose to save it as Configuration 1 or

Configuration 2. Not saving the configuration (or exit)

brings the interpreter system in the same state as it was

before you entered the configuration menu.

Load Configuration

A previously saved interpreter configuration can be

loaded. You can choose from 2 independent

configurations. After a load there will automatically be

a reset which will reboot the interpreter system without

affecting the conference system.

Not only the language settings for each booth will be

loaded but also the parameters in the option menu and

the initialization settings that were made after you saved

the configuration file. Although, you can alter these

parameters and initialization settings after a load

without affecting the language settings for all booths. In

this case a reboot will be necessary. This can be done by

activating the reboot in Reset menu item.

Choosing the language options for the different booths

A channel - Language

Through the language setting we can change the A

channel language of the booth. The A channel language

is the language to which a booth is assigned. For

example, when multiple languages are spoken during a

conference and the French language is one of the

spoken languages. Then you would add an interpreter

booth which translates the French language to e.g.

English and make the booth responsible for the English

language. To do this you would set its A channel.

B channel

The B-channel is the second language an interpreter

understands and speaks fluently. For example, Bob is

born in the U.K. and thus speaks English fluently. He

has studied the French, Spanish and Italian languages

which he understands and speaks fluently. He has been

assigned to the booth responsible for the English

language. During the conference English and French are

spoken. Bob translates the floor language to English

whenever French is spoken. Suppose now that Bob is

also responsible for the translation from English to

French. To translate to the French language Bob sets his

B channel on the French language.

In short: A translator may be responsible for multiple

languages. To be able to translate to these languages the

interpreter configures his interpreter desk accordingly.

The A channel is thus the main language the interpreter

Load

Configuration 1Press ENTER to Load

96

is responsible for (which cannot be changed from the

interpreter desk) and the B channel is the second

language an interpreter is responsible for (which can be

changed from the interpreter desk).

When you access the B-channel menu option you are

presented with a numeric choice. These numbers

represent the booths in the system. This option is

important when you want a specific language on your

B-channel after startup. Suppose you have three booths:

booth one is English, booth two is French, booth three is

German. For the third booth you want the B-channel to

be set to English as a default setting. Then you set the

B-channel to 1 during the configuration of the booth.

Remember though that the B channel can be changed on

the interpreter desk.

Auto-floor

Next to these settings the auto-floor option can be

activated. The auto-floor setting concerns working with

the B Channel on the interpreter unit. In circumstances

where the original floor-language is well known or not

so well known, two different operational procedures can

be used. Under normal circumstances the original floor

language is well known to all interpreters and they

listen to the original floor speech for translation. The

translations are then fed to the language distribution

channels so that the conference participants can listen to

them. In situations where interpreters are unfamiliar

with the floor speech and are therefore unable to

translate it, the system offers an automated relay

interpretation facility (auto-floor). An interpreter

assigned to translate the floor speech, translates it into

another language easily understood by other

interpreters. The floor language channel on all

interpreter desks (except the floor language channel of

the interpreter which translates the floor speech) will be

replaced by this transfer interpretation. This transfer

interpretation or auto-floor is then used as the base for

any further translations.

We have included two illustrations which explain the

normal interpretation and the relay interpretation for a

better understanding.

The first illustration show how a normal interpretation

works. Every interpreter translates the floor language.

In the next illustration, Russian is the floor speech and

the auto-floor facility is enabled for the Russian

interpreter’s desk. This interpreter selects outgoing

channel B and automatically relays an English

translation of the floor speech as auto-floor to all other

interpreter desks. His translation is therefore fed to the

English language distribution channel. The incoming

channel AUTOFLOOR indicator is activated on all

other interpreter desks to indicate that auto-floor is

active.

Auto-Floor

In short: Well, whenever an exotic (auto-floor) language

is spoken on the floor, it is translated. And it is this

translation of the floor speech that is used as a basis for

translation. Notice that the floor channel for the

98

delegates will not change. Auto-floor only concerns the

interpreter side of the system.

Initializing the interpreter system

When the full initialization of the interpreter system is

executed, all of the red signal rings of the interpreter

units will start flashing. The screen depicted on the left

will then appear on all interpreter desks. You will have

to manually configure the booth and desk number on

each interpreter unit. Press the MICRO button to send

the configuration data to the central unit. You will

notice that the other booths will have incremented their

BOOTH / DESK value. This allows you to step through

the initialization without much configuration.

You can end the initialization at the central unit after

you have initialized all interpreter desks end

Once the initialization is done, the LCD displays of the

interpreter units will show the different channels (A &

B) and other information.

If something went wrong during initialization then the

interpreter units will display an init refused screen.

When this happens you should try to reinitialize your

booths. If this doesn’t correct the problem check your

booth configuration.

When you traverse the Initialize Units menu you will

notice that there is an Add Unit menu option. Suppose

that we have an up and running system but you only

have one interpreter desk in the second booth and you

want to add another. You should then choose the Add

Unit menu item. The red signal rings of the interpreter

desks will now start flashing again and they will all

show the initialization screen (which is depicted in the

beginning of this section). You do not have to

reconfigure the interpreter desks you already initialized

previously. So go directly to the new interpreter unit.

Configure the booth and desk number of the new

interpreter unit and confirm your configuration.

Rebooting the interpreter system (TIS)

It is good practice to reboot the interpreter system

whenever you have made changes to your configuration

at the central unit. Rebooting the interpreter system

does not affect the conference system. This means that

you can make changes to the interpreter system during a

conference.

After loading a configuration from the configuration

menu it may not be necessary to reboot as this will

automatically follow after a load. However, if you

choose to reinitialize the interpreter system it is

recommended to reboot the system.

You can execute a reboot in case the interpreter system

needs a reboot by activating the reboot in Reset menu

item.

Options

Within the options menu of the interpreter system you

can alter the maximum number of booths, the maximum

number of desks per booth, the operating mode between

and within the booths.

A total of 28 interpreter booths can be connected to the

CONFIDEA CU and within each of these booths 8

desks can be placed. This means that up to 224

interpreter units can be used in a conference

configuration.

Maximum booths and desks

The maximum number of booths stipulates the number

of interpretation languages a conference system will

support. For example suppose you have a conference

room where English, French and German will be

spoken. You even have two interpreters for each

language. The only thing we have to do is configure the

system to have three booths and two desks.

The maximum number of desks defines the number of

desks each booth has. For example, if you set the

maximum number of desks to three, then this means

that each booth may have up to three desks.

Note: The number of interpreter languages supported by

your CONFIDEA CU does also depend upon the

licensing scheme you have bought. A standard system

can configure 2 languages.

Mode in and between booths

In the mode between booths three choices are available.

Mixed mode: more than one interpreter can translate to

the same language. The audio signals of the translation

are mixed and the interpreters are notified of this mixed

audio signal by the flashing of their microphone

indication led when they are translating simultaneously.

For example, booth 1 is translating the floor language to

French (on its A channel) and booth 2 starts to translate

to French (on its B channel). The delegates in the

conference room will hear the two translations mixed

through their headsets. The interpreters are notified of

this mixed audio signal by the flashing of the

microphone led and the red signal ring.

Override: any interpreter microphone in another booth

can override the current active microphone and become

active. The interpreter microphone that was just

overridden cannot return active again until the booth

responsible for the override deactivates its microphone.

Toggle Override: any interpreter microphone in another

booth can override the current active microphone and

become active. The interpreter microphone set to non-

active can return active for this translation by pressing

his microphone button again.

In the mode in booths only Mixed and Override is

available.

Mixed: multiple interpreters may simultaneously

translate to the same language. Whenever two

interpreters translate simultaneously they are notified by

the flashing microphone led and the flashing red signal

ring.

Override: this is similar to the Override mode of the

Mode between booths. The only difference here is that

the override happens on a per booth basis.

The interpreter menu - example Suppose we have the room configuration: a Wired


with a total of 2 languages spoken during a conference.

We will need up to 2 booths and 2 desks per booth for

dual interpreters to set up a correct configuration. You

have to have an additional license to be able to

configure more booths. This license can be purchased

trough your sales agent.

To be able to configure this we would need the

following hardware: one CONFIDEA CU and six

ID2500 interpreter desks. The number of conference

units depends on the conference room.

Let’s start setting up this system starting from a default

configuration. The setup will be described one step at a

time to make it easier to understand. If you feel that the

discussion of the setup is too detailed, feel free to skip

this section.

CONFIDEA CU. This has to be done before initializing

the interpreter desks and before altering the general

settings.

Suppose we want to make our booths responsible for

the following languages: booth 1 for English and booth

2 for Arabic. There are 2 possibilities to make the

necessary changes. You can start from a new

configuration or you can continue with the currently

configuration. Because we started from the default

configuration there will be no difference. Suppose we

choose to continue with the current configuration. Start

configuring each booth in the following sequence:

Alter the settings for the first booth. Start from the main

menu again. Press ENTER, choose Interpretation. Press

ENTER again, now choose Configuration. Press

ENTER. Scroll to Current and Press ENTER. Select the

booth number 1 and press ENTER.

Now we will alter the settings of booth 1. Turn the

wheel and select Language. Now press ENTER.

• Select your new language by turning the wheel. Our

choice for the language of booth 1 is English; so

select “ENG”. Press ENTER to confirm the choice

of our language.

102

NOTE: remember to press ENTER when you selected a

language, otherwise the language chosen will not be

confirmed.

• You have just configured the new language for

booth 1 in the CONFIDEA CU menu. These

changes have not yet been saved however. To save

these changes press EXIT. You should now go to the

screen depicted on the left. Turn the wheel to select

the Yes option and press ENTER to save. Our booth

configuration has just been saved.

• Suppose we wanted to change the auto-floor and B-

channel settings of our booth too. To do this, we

would have changed their settings before saving.

The B-channel may require some explanation

though. The B-channel menu on the central unit

displays numbers. These numbers reference the

other booths. Suppose you want booth 1 to have

Arabic as its default B channel. Arabic is the

language of booth 2. We will configure booth 2 in a

moment but suppose for know that booth 2 is

configured correctly. To set Arabic as the default B-

channel select B-channel = 2 and press ENTER.

Now save the booth as we have just configured the

settings.

• Configure booth 2 now by going through the steps

just described above. Set its language correctly to

Arabic (“ARA”) language. Configure its B-channel

and Auto-floor settings as you wish.

• After you configured and saved the booths, you also

need to save the global interpreter configuration as

Configuration 1 or Configuration 2. This can be

done by pressing the EXIT button in the Select

Booth menu. You should now go to the screen

depicted on the left. Turn the wheel to select the file

you want and press ENTER to save. Our

configuration has just been saved.

Altering the settings of each booth

Now that the booths has been correctly configured and

the room configuration has been saved as configuration

1 or configuration 2 we can start altering the settings for

each booth. The current default settings are the

following: number of booths is ‘2’, number of desks per

booth is ‘2’, mode between booths is Override and the

mode in booths is Override. As these default settings

will probably not match your needs, you can start

changing these settings at this moment. It is important

as Configuration 1Press ENTER to Save

103

to keep the correct order in the configuration procedure

to prevent unexpected errors. In this case the number

of booths and desk are the same as the default values so

it is not necessary to change this.

Configuring the interpreter units

Now that we are done configuring the booth on the

CONFIDEA CU, we will set up the interpreter desks so

that they will receive their information correctly.

• First, reboot the system. You may even check your

booth settings to see if they correspond to the

configuration we have set up in “Configuring the

booths

• ”. If everything was done correctly you will see that

these settings are correct.

• We are going to initialize the interpreter desks. Start

from the main menu again. Press ENTER, choose

Interpretation. Press ENTER again, now choose

Initialize Units and press ENTER.

We are now presented with a Full Init and an Add

Unit. The full init is used when we start with a fresh

system. The add option is used when you have a

configured a system and you want to add a new

booth or desk to you configuration. Enter the full

init mode. Press ENTER. You will notice that the

red signal rings of the interpreter desks will start

flashing. This means that they are in initialization

mode.

• Configure all the booths correctly. Once all booths

have been set correctly, go back to the central unit.

Ending the initialization mode at the central unit

• Back at the central unit. To stop the initialization

phase, press the ENTER button. If everything went

good you should see the screen depicted on the left

on an interpreter desk or a variant of that screen

depending on the booth and desk number of that

interpreter desk.

• This screen tells you that the interpreter unit has

been configured correctly. We can now start

working with the interpreter desks.

The “Add” init possibility

Suppose that we have an up and running system as the

one we just configured but you only have one

interpreter desk in booth 2 for the moment and you want

01 ENG 02 ARA00 00 00 00FLO FLO FLO FLO

104

to add an interpreter unit to this booth, so that it would

have 2 desks. You should then choose the Add Unit

menu item and press ENTER. The red signal rings of the

interpreter desks will now start flashing again and they

will all show the screen as depicted on the left. Ignore

the interpreter desks you already initialized and go

straight to the new interpreter unit. Set the booth of the

interpreter unit to 2 and the desk to 2 and confirm by

pressing the MICRO button. Now go back to the central

unit and press the ENTER button. You will notice that

the new interpreter desk has just been added to our

configuration.

Working with the interpreter units

• You can check the desk and booth number of an

interpreter desks by pressing the MUTE button,

keeping it pressed down and pressing the up or

down MENU buttons a couple of times.

• You cannot alter the A channel of an interpreter

desk at the interpreter desk. The A channel of a

booth is fixed.

• However, you can change the B channel of an

interpreter desk by keeping the B button at the right

of the screen pressed down and pressing up or down

simultaneously. This will cycle through all the

available languages. This means that an interpreter

can choose his own B channel.

• The loudspeaker channel can be changed by keeping

the LS CHAN. button pressed down and pressing the

up and down buttons simultaneously.

• Relay 1 can be changed by keeping the RELAY 1

button pressed down and pressing the up and down

buttons simultaneously.







• The green LEDs at the right of the screen indicate

which channel you have currently selected.

• An interpreter is currently translating the language

of an A or B channel when the red LED at the right

of the screen is lit.

105

The New function

Like already mentioned, you can begin a new

configuration by selecting the new menu. As soon as

you enter the new menu the current configuration will

be deleted. However, if you choose not to save the new

configuration, the previous configuration will be

restored.

After you made a new configuration you can alter the

maximum number of booths, the maximum number of

desks per booth, the operating mode between and within

the booths in the option menu.

Suppose we use currently a configuration that is saved

as Configuration 1 but we want to make another

configuration without deleting Configuration 1.

Immediately beginning with changing the options

needed for Configuration 2 will change the options for

Configuration 1 because after you altered the options a

general save follows which affects the current

configuration, in this case Configuration 1. To avoid

this, start with making a new configuration and save it

as Configuration 2. Afterwards, alter the necessary

options. Now you have two working configurations that

you can load at any time.

106

Auxiliary menu – overview

Usage

The auxiliary menu is used to configure all inputs and

outputs of the CONFIDEA CU. A number of external

devices, like a CD player or a microphone with

preamplifier, could be connected to the auxiliary input.

Other devices, like a recording unit, could be connected

to the auxiliary outputs. Also remote conferencing is

possible between two conference rooms.

The devices which will be connected to the central unit

differ from configuration to configuration. Therefore

the menu allows the auxiliary inputs and outputs to be

configured as needed.

The outputs

The system has 6 auxiliary outputs. The configuration

of the first auxiliary output, labeled AUX OUT 1 on the

back of the CONFIDEA CU, differs from the other

outputs as the channel of this auxiliary output is fixed.

The channel of this output is the floor channel. The

AUX OUT 1 is an XLR-3M output or the first output

that is contained within the D-sub connector. The

volume difference between AUX OUT 1 on the SUB-D

connector and the AUX OUT 1 on the XLR socket can

be adjusted by changing the VOLUME XLR in the

AUX OUT 1 menu item. By default there is no

difference. Also, it is possible to enable remote

conferencing. This will be discussed later in this

paragraph.

The other outputs, AUX OUT 2 – 3 – 4 – 5 – 6, are

contained within the D-sub connector. The pin

assignment of this connector has been discussed above.

Volume: The volume of the outputs can be configured

to the correct level. Just enter the Volume menu item

and set the appropriate level. The volume level will

change as the wheel is being turned. However, if you

want to save the settings so that the system always

booths with a certain volume level on that port, then do

not forget to press the ENTER button to save the new

value.

Channel: The audio signal of the interpretation channel

which an auxiliary output should output is configured

within the Channel menu item. The channels out of

which can be chosen depend on the licensing scheme of

107

your CONFIDEA CU. If you have a basic license, then

you are able to choose two channels.

Status: The status setting of the auxiliary output enables

or disables the selected output.

The headphone output channel on the front of the

central unit is the same as AUX OUT 6. The volume

difference between AUX OUT 6 on the SUB-D 15

connector and the AUX OUT on the headphone jack

can be adjusted by changing the Vol. Headphone in the

AUX OUT 6 menu item. By default there is no

difference.

The inputs

The system has two auxiliary inputs. These inputs are

labeled AUX IN 1 and AUX IN 2 at the back of the

CONFIDEA CU. The two inputs are both XLR-3F

connectors.

Level: The level of the inputs can be configured to the

correct level. Just enter the Level menu item and set the

appropriate level. The audio level will change as the

wheel is being turned. However, if you want to save the

settings so that the system always booths with a certain

volume level on that port, then do not forget to press the

ENTER button to save the new value.

Sensitivity: The sensitivity of the input channel can be

altered through this menu option. The sensitivity setting

has two options: LOW and HIGH.

Status: The status of the auxiliary input enables or

disables the selected input.

echoing. The screen you should go to is the screen

depicted on the left.

NOTE: keep in mind that for remote conferencing only

AUX IN 1 and AUX OUT 1 can be used.

External Equalizer

To avoid disturbing feedback or to equalize the audio

signals it is possible to interconnect external equipment

to the central unit. When such external equipment is

used, the external equalizer option should be set. When

setting the status to ON, the audio floor channel will be

disrupted in a way that all input signals (except AUX IN

1) will be directly routed to the AUX OUT 1. The signal

present on AUX IN 1 will be used as the new floor

channel. This way it is possible to use external audio

equipment like equalizers or feedback destroyers. The

schematic picture below summarizes this feature.

External Equalizer =OFF

External Equalizer = ON

Remark :

(Re)Setting the status for the external equalizer to

ON will change some other functions automatically:

o AUX IN 1 status = ON

o AUX IN 1 level = 18 (nominal)

o AUX IN 1 sensitivity = HIGH (+12 dB)

o AUX OUT 1 status = ON

o AUX OUT 1 volume = 18 (nominal)

o Remote conferencing = OFF

The settings can still be changed manually to desired

values.

Auxiliary menu - example

Recording or sending the audio signals of our translations to other devices

Suppose now that you have some additional audio

equipment installed which you will use to record

translations or which are used to sent the audio signal of

these translations to another device. For this you have to

configure the auxiliary outputs. The Aux Out 1 audio

signal is always the floor channel signal; you cannot

change this. However, the Aux Out 2, Aux Out 3, Aux

Out 4, Aux Out 5 and Aux Out 6 audio signal can be

changed. We will explain how to set the

(audio/interpreter) channel which should be sent to

these outputs on the central unit.

• Start from the main menu, and press ENTER. Now

choose Aux-In/Out and press ENTER. Select Aux

Out 1 and press ENTER. You can change the

volume and the status of the Aux Out 1 output

signal. The volume choice is self-explanatory and

the status menu has two options: On and Off. Set the

status to On if you want to enable the signal sent

out.

• The other output menu choices contain the same

volume and status options. In addition to these

options a channel option is also present. What does

the channel stand for? Recall that we just configured

our interpreter system as explained above. English is

on channel (booth) 1 and Arabic on channel (booth)

2. The numbers describe the booths in our system.

You can therefore set which audio signal you want

to send to your output.

111

System menu – overview

Usage

The system menu contains system wide monitoring and

configuration options. Five different options are

present:

Diagnostics

An overview of the conference terminal strings

connected to the central unit is provided in this menu. It

is also what you’ll see on the main screen (with the

volume bar). Next to this overview you can also check

if there are communications errors on specific ports

from within the Port Errors menu item. The symbol

representing the error will then appear on that port.

Explanation of the symbols:

: means that there is a string of conference terminals

connected to the port described under the symbol.

: is the opposite of the above symbol. It stands for

an unconnected port or a wrongly connected string of

conference terminals. (No string or a wrongly connected

string of conference terminals is connected to that port

number). In the case you have a string of conference

terminals connected to the central unit and the symbol

remains, then check if you have connected the IN port

of the conference terminal to one of the six ports.

: is the symbol representing the communications

error. It will only appear on a port to which a string of

conference terminals is connected as no

communications errors can occur on an unconnected

port. Pressing ENTER will reset the error indicator.

Camera control

If you ordered a Wired Confidea Digital Conference &

Interpretation System with camera control, then this

option is enabled through your licensing scheme.

Otherwise you cannot alter the settings of this option.

More information can be found in appendix A.

Control Panel

The optional control panel must be enabled through this

menu item. A control panel is a miniature physical

representation of the conference room. With this control

The license menu – overview

Usage

The CONFIDEA CU comes with a standard license

which enables the configuration of two interpreter

languages and camera control.

New licenses can be applied for to enable a higher

number of interpreter languages .

The license menu can be used to view:

• the serial number of the CONFIDEA CU,

• and the current license of the CONFIDEA CU.

You can also enter a new license into the CONFIDEA

CU so that the number of configurable interpreter

languages is upgraded. To enter a new license you

should have received a license code in the following

form:

Troubleshooting

If problems occur …

Replacing a fuse

If the fuse of a central unit has blown, the subsequent

delegate units cannot be powered. To replace the fuse of

a central unit, proceed as follows:

• Use a screwdriver to carefully loosen the fuse holder

and pull it out completely.

• Remove the fuse. This is the faulty fuse.

• Now replace the fuse.

The specifications for the replacement fuse are shown

above the fuse holder.

Tips for troubleshooting

Delegate unit does not work

Check if the system cable between the central unit and

the delegate unit is defective or if the system cable has

been pulled out.

Check if the central unit is connected to the mains and if

they are turned on.

No microphones except the chairman microphone can be set active

Check the TMS submenu on the central unit. Check if

the maximum number of microphones that are allowed

to be up is not set to zero. If this is the case, alter this

value and set it to at least 1.

116

Maintenance and care Use a damp cloth for cleaning the components of the

conference system from time to time. Never use

solvent-containing cleansers, as these could damage the

surfaces of the components.

117

Appendix A: Camera Control Protocol

Overview The Wired Confidea Digital Conference &

Interpretation System supports a camera control. The

commands which the camera control should understand

will be described shortly.

The camera control must be connected to the

CONFIDEA CU through a RS232 connection. The

appropriate port to use on the CONFIDEA CU is

COM2. The communications port COM2 operates at a

speed of 19200 bits per second.

A complete overview of the settings of the

communications port for the camera control:


Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

Note however that in order to activate the camera

control on the central unit you have to own a license

which entitles you to.

118

Commands

All commands sent by the CONFIDEA CU start with a

‘%’ sign. The last character is a character which states

the end of the transmission. Just before the end of

transmission character, there are four characters within

the command sent to the camera control which account

for the CRC checksum. The CRC checksum is in

uppercase hexadecimal form while all other numbers

are in decimal form.

The protocol is described as follows:

STX ‘%’ data CRC ETX

With:

STX = start transmit char (0x25 = ‘%’)

ETX = end transmit char (0x0D)

CRC = 16 bit sum of the ASCII characters

between STX and CRC

We will adopt a certain notation to explain the messages

sent. All separate entities in a message are represented

between curly brackets. If the contents of such an entity

is also between quotes (‘ ‘) then this means that this is a

literal string. Otherwise it describes the logical entity. A

logical entity will also contain a number between

brackets. This number states how many characters the

entity will exist of. If the subtext 1+ is attached to the

entity between curly brackets, then this means that one

or more occurrences of this entity may occur.

Maybe this notation seems a little hard to comprehend

at first, but some examples should clarify them.

Whenever a microphone of a delegate or the

microphone of the president is activated, then a

command is sent to the camera control. Whenever an

active microphone is deactivated, another command is

sent to the camera control.

• The microphone of the president is activated:

‘%’‘P’Microphone number (4) CRC (4)

• The microphone of the president is deactivated:

‘%’‘p’Microphone number (4) CRC (4)

• The microphone of a delegate is activated:

‘%’‘M’Microphone number (4) CRC (4)

• The microphone of a delegate is deactivated:

‘%’‘m’Microphone number (4) CRC (4)

119

The remaining commands are control commands.

• First microphone has been activated and the camera

control should become active.

‘%’‘1’‘R’‘00’CRC (4)

• All active microphones are deactivated and the

camera control should reset itself to a neutral

starting position.

‘%’ ‘1’‘r’‘00’CRC (4)

• At a time-interval of around 5 seconds a

synchronization message is sent to the camera

control. The message contains all the numbers of the

active microphones or the number 0 to stipulate that

there are no microphones active.

‘%’‘S’Microphone Number (4)1+CRC (4)

• All active microphones are deactivated

simultaneously.

‘%’‘V’‘0000’CRC (4)

Examples

If the president microphone is activated, and the

president microphone has the number ‘0001’ then the

following message is sent: %P00010111

When the president microphone is deactivated, then the

following message is sent: %p00010131

If a delegate microphone is activated, and that delegate

microphone has the number ‘0003’ then the following

message is sent: %M00030110

When the delegate microphone is deactivated, then the

following message is sent: %m00030130

Suppose now that the delegate microphone with number

‘0003’ is active. On a synchronization check the

synchronization message will look like this:

%S00030116

Suppose now that the delegate microphones with

number ‘0002’ and ‘0004’ are also active. On a

synchronization check the synchronization message will

look like this: %000300020004029C

When no microphones are active, then the following

synchronization will be received: %S00000113

When the camera control system should reset itself to

its start position, then the following message will be

received: %1r000052

120

When all microphones are deactivated simultaneously,

then the following message is received: %V00000116

121

Appendix B: Control Panel Protocol

Overview The Wired Confidea Digital Conference &

Interpretation System supports a control panel such as

AMX, Crestron (ie Dataton, …). The commands which

the control panel should understand will be described

shortly.

The control panel must be connected to the CONFIDEA

CU through a RS232 connection. The appropriate port

to use on the CONFIDEA CU is COM2. The

communications port COM2 operates at a speed of

19200 bits per second.

A complete overview of the settings of the

communications port for the control panel:


Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

REMARK : When TCS 2500 Application

Programming Interface is used to manage the Wired

Confidea microphone system and voting system , then

the appropriate port to use on the CONFIDEA CU is

COM3.

122

Commands

All commands sent by the CONFIDEA CU start with a

‘%’ sign. The last character is a character which states

the end of the transmission. Just before the end of

transmission character, there are four characters within

the command sent to the control panel which account

for the CRC checksum. The CRC checksum is in

uppercase hexadecimal form while all other numbers

are in decimal form.

The protocol is described as follows:

STX ‘%’ data CRC ETX

With:

STX = start transmit char (0x25 = ‘%’)

ETX = end transmit char (0x0D)

CRC = 16 bit sum of the ASCII characters

between STX and CRC

We will adopt a certain notation to explain the messages

sent. All separate entities in a message are represented

between curly brackets. If the contents of such an entity

is also between quotes (‘ ‘) then this means that this is a

literal string. Otherwise it describes the logical entity. A

logical entity will also contain a number between

brackets. This number states how many characters the

entity will exist of. If the subtext 1+ is attached to the

entity between curly brackets, then this means that one

or more occurrences of this entity may occur.

Maybe this notation seems a little hard to comprehend

at first, but some examples should clarify them.

Whenever a microphone of a delegate or the

microphone of the president is activated, then a

command is sent to the control panel. Whenever an

active microphone is deactivated, another command is

sent to the control panel. This is also valid when a

microphone goes into request.

The control panel is also able to send commands to the

central unit. One command is sent to activate/deactivate

a microphone. There is also a command that can be sent

to the central unit if you want to reboot the control

panel. Also the test generator can be activated or

deactivated. Other commands allows you to alter the

volume and conference mode.

We will divide the discussion of the commands into two

categories. The first category describes the commands

coming from the central unit and going to the control

123

panel and the second category describes the commands

coming from the central unit and going to the control

panel.

The Commands sent by the central unit and received by

the control panel:

• A microphone is activated:

‘%’‘1’‘L’Microphone number (4) CRC

• A microphone is deactivated:

‘%’‘1’‘l’Microphone number (4) CRC

When configured, the chairmen units can initiate an

action by selecting a user defined menu and pressing

a function key.

The “menu ID” indicates the selected user menu on

the delegate unit:

Appendix C: Analog Output Device (AOP) manual

Overview The AOP2500 unit allows connecting of analog

equipment (such as IR modulators, sound reinforcement

amplifiers, analog cassette recorders etc…) to the

CONFIDEA CU Digital central unit. It is equipped with

9 D/A converters and outputs the floor language

channel and up till 8 translated channels. Power is taken

from the CONFIDEA CU.

Channel 0 is always the floor language. Channel 1 can

only be configured freely by rotary switch programming

(internal). Channels 2 to 8 are the next consecutive

channels of channel 1.

Three LED’s are on the front: one to indicate power,

one to indicate sync and one to indicate that modulation

is present at the floor channel.

Connectivity

• Nine 3 pin XLR M connectors (balanced, X former

coupled).

• Two RCA phono connectors for floor language

output.

• Eight RCA phono connectors for translated

language outputs.

• One 4 pin Phoenix connector for remote control.

• 2 RJ 45 connectors for separate loop-through digital

bus cabling.

Configuration

• Channel 0 (CH0) is always the floor language.

• Channel 1 (CH1) is the reference channel and is

only by hardware configurable. The other channels

(CH2 to CH8) are the next consecutive channels of

channel 1.

• The configuration of channel 1 depends on the

Rotary switch and the DIP switches. The value of

channel 1 is the sum of the values of the Rotary

switch and the DIP switches.

• The value of the Rotary switch is marked on the

switch.

• The value of the DIP switches is 0 if both switches

are off, in all other cases is the value 16.

Remote Control

There is a voltage free contact that is closed when a

microphone is active and that is open when no

microphone is active. The CONFIDEA CU controls this

voltage free contact. At the backside of the unit, the

Phoenix connector is numbered from left to right (non

removable connector).

Maximum load

current(continuous) = 1A

Maximum load current

(continuous) = 1.8 A

Maximum load voltage =

60V

Maximum load voltage =

60V

On-Resistance = 0.5Ω On-Resistance = 0.15Ω

This connector Phoenix is directly connected to the

LCA710 driver IC.

131

Leds on the front panel

• When the AOP2500 has modulation present at the

floor channel, the floor led (green) will illuminate.

(The voltage free contact will close when the floor

led illuminates).

• When the AOP2500 has sync, the sync led (green)

will illuminate.

• When the power of the AOP2500 is good, the power

led (green) will illuminate.

Appendix E: Connecting Confidea Access Point to CONFIDEA CU

Overview When Confidea system is used in “TCS2500 coupled “

mode , the Confidea Access Point needs to be connected

to one of the PORT1-6 sockets of the CONFIDEA CU

central , just as any other delegate unit

Via this connection , the communication and audio

signals between Confidea Access Point and

CONFIDEA CU are handled.

This connection also provides DC power supply from

the CONFIDEA CU to the Confidea Access point. So

no separate 220Vac/24Vdc adapter needed to feed the

Confidea Access Point, although it is still allowed to use

one.

Initialisation of Confidea WDU’s is done just as any

other type of delegate unit
