1 Sepura SRM2000 – IP223 Interface

1 General This application note describes the interface between the IP223 and the Sepura SRM2000 Mobile TETRA radio. The contents include the physical connections and diagrams, the setup of the IP223, setup of the SRM2000 and CSoft PC console configurations. The IP223 to SRM2000 interface give the Dispatcher the ability to control a TETRA Radio asset from a remote IP based hardware or PC dispatch console. Giving connectivity through nation wide TETRA digital trunked systems.

1.1 Hardware Required These item will be needed to connect the IP223 to the SRM2000 Radio ITEM: MFG Part Number IP223 Ethernet Remote Panel 0101240 IP223-SRM2000 Interface Assembly 301961000 Sepura Console SRM2 300-00083* Sepura Application Interface Unit (AIU) 300-00087* Sepura Interface Cable 300-00067 IP223 DB9 Splitter Cable 301953000** *Either the console or the AIU will be needed, but not both. **If both IP223 Radio ports are interfaced to serial data controlled devices, such as the SRM2000, the DB9 Splitter Cable will be required to split the single DB9 port. 2 IP223 and Cable assembly configuration

2.2 IP223 Webpage Setup To enable the IP223 to Sepura SRM2000 interface, the IP223 will need to be placed in TETRA Radio Mode. This is done in the Multicast Port Number Setup page, as shown in Figure 1. Here Channel One is TETRA Radio enabled by using the pull down menu under Channel Type.

Figure 1 Enabling TETRA Radio Mode

Once the TETRA Radio Mode is enabled in the Multicast Setup, the Per Line Setup page will display only those items necessary to configure a TETRA Radio. Figure 2 shows an example of how the TETRA Radio Mode and SSI parameters may be set. The Mode settings are: Trunked Group Call (Trunked GC) Direct Group Call (Direct GC) Trunked User Defined Scan List (Trunked UDSL) Trunked Half Duplex Private Call (Trunked HDPC) Trunked Full Duplex Private Call (Normal Phone Call see notes)

2.2.1 Trunked GC A half duplex point to multi-point call where immediate communication can take place between the calling and the called users. As named, this call is trunked and requires network access.

2.2.2 Direct GC Communication with other TETRA radios without the use of the network. This is called Direct Mode Operation or DMO.

2.2.3 Trunked UDSL The User Defined Scan List is a mean to scan specific group that are predefined in the radio and in the IP223. A UDSL is a collection of pre-defined talk group (or function tones) settings. A UDSL string is entered in the SSI parameter field and is separated by the semicolon as shown in the Figure 2 below. A UDSL string can accept up to 10 Trunked groups.


If a F-Tone number in the UDSL is not assigned to Trunked GC, then the scan list is invalid and the IP223 will not change to that F-Tone. If the F-Tone is correctly configured and in a UDSL, but the group number assigned to the F-Tone’s Trunked GC is invalid, the IP223 will change to that F-Tone, but the invalid group number will not be scanned. In Figure 2, F-Tone 11 is an example of an improperly configured UDSL. Any attempts to change to this F-Tone will not occur as the F-Tone entries correspond to non-Trunked GC channels. The IP223 will catch this improper assignment and skip a channel change to that F-Tone. Transmissions will only occur on the first entry in the UDSL. For example, UDSL (1;2;3;4;5) if scanning stops on group assigned to F-Tone 4, only group 1 is available for retransmit.

2.2.4 Trunked HDPC Half duplex point to point call between caller and called units. Each unit asks permission to transmit before each transaction.

2.2.5 Trunked Full Duplex Private Call (Phone Mode) There is not a specific programming dialog in the IP223 for this mode. It is completed by adding a phone line to the Dispatch console. If more than one phone mode line exists on the console, then another line for the TETRA Trunked FDPC will need to be added. This line should not use the phone mode pool function for selecting the phone asset to use when calling, but instead select the specific line for the Sepura Radio. Once this is complete, normal phone calls to TETRA radio subscriber units can be made. Also, the F-Tone that the IP223 TETRA interface was last on cannot be Direct GC(DMO), or the phone line will return not available. Any trunked mode configuration will work.

2.3 IP223 to SRM2000 Interface Cable The following drawing shows the pin connections and hardware assembly.


3 Radio Information: 3.1 Radio Personality Configurations The following Figures show required setting in the Sepura SRM2000 Radio. The Peripheral Equipment Interface (PEI) port needs to be configured to allow the IP223 direct control. Misc Tab General PEI Parameters. Figure 3 show the General PEI Parameters page. The baud rate format needs to be configured for the IP223 to communicate with the radio. The baud rate should be set to 19200 on logical port 1. Set Serial Port Usage to Normal AT on first physical port. PEI Accessory type to Remote Mic

Figure 3 SRM2000 Serial Port Setup


Misc Tab PEI Profile Parameters: These parameters are required to route voice and data to the appropriate external ports. The proper routings are shown in Figure 4. CC Voice and Data in both Trunked and Direct Mode should be routed to Logical port 1. Trunked Mode Services: SDS Status and TL should be set to Route to MT.

4 Connecting the IP223 and the SRM2000 Figure 7 shows the complete cable assembly connections. There should be no confusion as to the connections, as each cable has a unique end. The cable descriptions follow: DB25 to 10 pin Aux: Used to route audio from the IP223 to the SRM2 console panel. The DB25 can be connected to radio 1 or radio 2, but the 10 pin Auxiliary connector will need to be connected into Audio Accessory Interface 1. See Figure 9 and Figure 10.


Figure 7 Complete Cable Assembly With SRM2 Console panel.

Figure 8 Shows the rear view of the IP223 and the SRM2000 radio. The Serial cable is connected to Interface One on the SRM2000 radio and the DB9 on the IP223. The black transceiver cable is connected from SRM2000 Interface 2 on the radio, to the Transceiver port (Middle connector) on the SRM2 console panel and AIU. Not shown is the power connection, which will be connected to the Power/Audio port on the radio, then to the power supply.

Figure 8 Rear view of cable connections


Figure 9 shows a close up of the connections to the SRM2 console panel. The middle connector is the radio transceiver connection. Audio and serial data are routed to the radio from this port. The far right connector is the Audio Accessory Interface 1. Audio from the IP223 is routed to this connector. The unused connector is the Audio Accessory Interface 2. Audio Accessory Interface 2 is not the preferred connector for the IP223 Audio interface.

Figure 9 Cable connections to the SRM2 Console Panel.

Figure 10 shows the connection to the Applications Interface Unit (AIU). This can be used instead of the SRM2 console panel shown above. The connections are the same.

Figure 10 Cable connections to the AIU.


Figure 11 show the front panel display of the IP223. When Radio one or two is configured for TETRA radio mode and the IP223 makes the connection to the Sepura SRM2000 radio, the display “Sepura”. Top row will display for radio one, bottom row for radio two.

Figure 11 View of IP223 display after connections established.

5 C-soft Full Duplex Individual Call Setup The IP223 uses C-soft phone function for the Sepura full duplex individual call operation. NOTE: This example shows a basic setup for C-Soft. Please refer to the User manual for other Vega IP based consoles if necessary

5.1 Setup IP Multicast List

Figure 12 Setup IP Multicast List – Sepura Full Duplex Individual Call

Figure 12 shows an example of setting a line in C-soft for Sepura full duplex individual call. In this example, the Line Type is selected as Phone mode. The Line Name is arbitrary and called Line 2 in the case. The Rx port numbers need to be unique. Typically they are just the next number in a standard assignment sequence. The Base Radio IP address will be the IP address of the IP-223 that is connected to the Sepura radio.


5.2 Set Global Parameters

Figure 13 Setup Global Parameters - Phone Ring Multicast and Port

Figure 13 shows the Individual Ring Multicast and Port number setting. This value will be the same as that shown in Figure 1.

5.3 C-Soft Phone Control Buttons

Figure 14 CSoft Individual Control Buttons Setup

Error! Reference source not found.14 shows a few of the basic C-Soft Individual Control buttons. Any button can be configured for a task by Right-Clicking on the button, then using the UI Element Function pull down menu. In this case, Phone – On/Offhook was selected and line 2 of the C-soft is selected as phone line. The Remote Phone Line Select tab shows that select line 1 in the case of the IP-223 because line 1 is selected as TETRA radio in Figure 1. Please refer to the C-Soft manual for further details on the button configuration. Figure 15 shows an example of the keypad configuration. The B key is used as a send button in manually dialing an individual call. Take the individual line offhook, dial the number, then press the B key to connect the call.
