Transient Pressure Monitoring System...The Transient Pressure Monitoring System is easy to set up and use. The first three sections of this manual will tell you everything you need

Transient Pressure Monitoring SystemThe Transient Pressure Monitoring System is really two instruments that provide pressure informationregarding pipelines:

the Transient Pressure Monitor, and the Differential Pressure Monitor

The Transient Pressure Monitor Processor also produces an output signal during transients. The user canspecify how this output is generated.

The Transient Pressure Monitoring System is comprised of the following components:

The Transient Pressure Monitor is a uniqueinstrument for detecting potentially damagingpressure transients in pipelines. The systemcontinually monitors the pressure in the pipe, andlooks for rapid changes in pressure. These arerecorded in the system Processor. You use awireless device to collect the data from theProcessor and to make adjustments. The data canbe analyzed later on your PC. The TransientPressure Monitor can only monitor one pressuresensor at a time.

The Differential Pressure Monitor measures andrecords two pressures simultaneously. It recordseach pressure at a fixed rate specified by the user.It does not attempt to detect pressure transients.You use a wireless device to collect the data fromthe Processor and to make adjustments. The datacan be analyzed later on your PC.

The Transient Pressure Monitoring System is easy to set up and use. The first three sections of thismanual will tell you everything you need to know to use the system. The other sections will help youconfigure the system to your needs.

Getting Started

Personal DigitalAssistant (PDA)

A PocketPC PDA is the primary device for the user interaction.A laptop with a WiFi card can also be used. (Any desktop orlaptop on a wired LAN can also be used, if the Processor isconnected to the LAN.)

Processor The Processor processes all of the input signals, and performs allof the logic in the system. It also stores all of the historical datauntil it is retrieved using the PDA.

Communications WiFi is the primary communications mechanism. (A wired LANcan also be used.)

Sensors Depending on the operating mode, 1 or 2 pressure sensors areused to measure the pressure in the pipe.

Data AnalysisPrograms

PC programs that retrieve the stored data files from the PDA, andand convert and display the data. The data is also stored in adatabase for analysis by other programs.

Note: This manual will refer to all of the remote devices that are used for userinteraction (PDA, laptop, desktop, etc.) as the PDA, unless there are differencesin their operation.

The PDA displays all ofthe system’s informationto the user, and processesall of the user inputs. Italso retrieves thehistorical informationfrom the Processor.

The Processor processesinput from the Sensors,and creates all of thesystem information. Itcontinuously monitors thepipe and stores the datainternally.

The Sensors measure thepressure in the pipe at twolocations.

2) Install the QViewPlus software on your PDA.

3) Check the hardware installation.

When you are ready to begin analyzing the data, please perform step 4.

4) Install the QAnalyze and ConvertData software on your PC.

* QViewPlus, QAnalyze, and ConvertData are licensed programs from Qameleon Technology, Inc.

Connecting the hardware for the Transient Pressure Monitoring System is easy. The steps to be followed dependon the options that are included.

Please do the following:

Important: If you purchased the PDA option with your Transient PressureMonitoring System, skip step 2 and go on to step 3.

If you are providing your own Pocket PC PDA or laptop, pleaseperform step 2.

Installing the Hardware

1) Install the Processor in a convenient location. It can be permanently mounted usingthe mounting holes, or just placed on a shelf or the ground. The Processor isweatherproof, and can be installed outside.

If you are using the small black standard antenna alone, the Processor needs to belocated where there is no radio shielding between it and the remote WiFi device(PDA or laptop). If you must locate the Processor inside of a cabinet, underground,or in some other inaccessible location, you will need to use the Antenna ExtensionCable or the Outdoor Antenna.

The mounting holes are under the box cover. Remove the 4 screws holding thecover in place. The mounting holes are outside of the sealing edge.

External brackets are available for mounting the Processor without opening thecase.

Important: You must follow the important instructions when replacing thecover. Improper tightening of the screws may cause the case to leak.This will void the warranty.



There is no power switch. Just connect the power cable to the Processor. The Processor will startcommunicating in approximately 45 seconds.

The Processor needs to have an antenna connected to operate.

2) Install the Sensors

3) If necessary, Install the Antenna

4) If necessary, Install the External LAN

5) If necessary, Install the AC Adapter or battery.

Installing The Antenna



In most cases, the standard antenna will besufficient. Attach the antenna to the antennaconnector on the Processor, and turn it so that itis vertical. It does not matter if the antenna ispointed up or down.

The antenna radiates as a cylinder parallel tothe antenna shaft. Mount the antenna so thatthe shaft is perpendicular to the PDA. Youshould test the reception before permanentlyattaching the antenna.



First, locate the antenna in a clear location for the signal. Attach the antenna to a structure where there will notbe any metal blocking the path to the PDA or laptop. It is not essential to have the antenna located at a highelevation.

The Outdoor Antenna Option is used when the antenna will be exposed to the weather.

After the antenna has been installed, route the cable to the Processor and connect it to the Antenna Connector.

The Transient Pressure Monitoring System has 2 sensors that measure the pressure in the pipe. The sensors canbe used as either Sensor 1 or Sensor 2. Remember where each sensor is located, since they are referred to bynumber in the monitors.

The Antenna Extension Cable Option is usedwhen the Processor is located underground,inside a metal enclosure, or in some locationwhere the radio signal will be shielded. Attachthe standard antenna to the cable, and thenconnect the cable to the Processor.

The antenna is mountedvertically, with the cable

pointing downward.

The antenna mounting kitconsists of a metal bracket that

attaches to the antenna. Clamps,suction cups, and mountingscrews are also included..

Installing The Sensors

Note: The sensors that came with your system may have different pressure ranges. They are alreadycalibrated for their respective locations.

If you swap Sensor 1 and Sensor 2 as they plug into the Processor, you will have to recalibrate thesoftware. This can be done using the Calibration screen of the Differential Pressure program.



The appearance of the sensors may differ from the pictures, but they are connected in the same way.

Plug the cables from the sensors into their corresponding sockets on the Processor.

The sensors are already calibrated for their respective positions. If you are replacing the sensors, or switchingtheir positions as they plug into the box, follow the instructions in the Calibration Screen in the DifferentialPressure program.

The External LAN Connector Option is used when the Processor is connected to another computer using a wiredLAN.

The sensors have 1/4" NPT male fittings. Thesensors can be attached to the pipe in any desiredlocation using the appropriate fittings.

You may wish to install the sensor with a valve anda pressure gauge. While this is not necessary it willmake it easier to recalibrate the sensor, ifnecessary.

If you plan to use the system to monitor a pressurereduction valve or a pump, install one sensor oneach side of the device. Sensor 1 is often used asthe input, and Sensor 2 the output.

It is best to locate the sensor horizontal or pointingdownward so that no air is trapped in the line. Thiswill improve the accuracy of the readings.

Using The External LAN Connection



Make sure the PC and the Level 1 are on the same network and that the QViewPlus program is installed on any

The External LAN Cablesupplied with this option is20' (6 M) long. On one end is aweatherproof connector to matewith the socket on the Level 1module. On the other end isstandard RJ45 modularconnector. This is a CAT 5cable.

For direct connection to a PC,plug the External LAN Cableinto the Level 1 module andtighten. Plug the other end intothe Ethernet adapter on the PC.

When using a hub, plug theExternal LAN Cable into theLevel 1 module and tighten.Plug the RJ45 connector intothe hub.



PC you wish to use.

The AC Adapter is designed for 100-240VAC 50-60Hz. Plug the adapter into the Power Connector on theProcessor and into an AC outlet.

If you are going to use the system temporarily, you can use 12 Volt batteries to power the Processor. Justconnect the power cord to the battery (Red +, Black -) and to the Power Connector on the Processor.

Installing The AC Adapter and Connecting Power

AC Adapter Power Cable (optional)

Processor

Important: The AC Adapter is not waterproof. Make sure it is protected.



Occasionally, the sensors may pick up noise from electrical equipment nearby. This may be from high intensitylamps, large motors, or transformers. It is not always possible to predict this noise, and may not be present at all.

Grounding the TP-1 to an earth ground will usually eliminate the noise. Check the data from the TP-1 to see ifthere is noise affecting the readings

The Processor has an internal clock that it uses to timestamp all of the sensor readings. While this is a fairlyaccurate clock, very precise time information can be provided using the optional GPS receiver.

Important: Be sure to connect the RED clip to the POSITIVE terminal and the BLACKclip to the NEGATIVE terminal of the battery. If the polarity is reversed, thefuse will blow. See the "Replacing the Fuse" section for instructions.

Grounding the Processor

If you are using the AC Adapter, just plug itinto a 3-prong grounded outlet. This willautomatically ground the Processor.

If you are using a battery to power the unit,you should not need a ground connection. Insevere noise situations, you should connect awire from the NEGATIVE terminal of thebattery to something that is grounded to theearth. This can be the pipe itself, anotherpipe, the body of a pump, or a metalenclosure that is electrically grounded. Youshould test the system for noise to be surethat the noise is gone.

Installing The GPS (optional)



After the GPS receiver has been installed, route the cable to the Processor and connect it to the GPS/SerialConnector.

The GPS receiver is a self-contained device ina waterproof housing. The receiver must belocated where it has a clear view of the sky,preferably outside or near a window. It is notessential to have the receiver located at a highelevation.

The unit is oriented with the domed partfacing upward. In many cases, it can simplybe placed on a flat surface. If desired, it canbe attached to a plate or the top of a cabinetusing the threaded holes in the bottom.

Use the GPS Setup Program to ensure thatthe receiver is in a good location.



The Processor can communicate with certain devices over 2-wire RS485 using an external adapter. The adapteris plugged into the RS485 socket on the Processor. The use of the RS485 interface is specific to your product.

Installing The RS485 Adapter (optional)



The connections to the RS485 adapter are as follows:

Please check the manual for your remote device for its RS485 connections.

The Transient Pressure Program continually monitors the sensor for rapid changes. When a transient is detected,the Processor turns on a relay. The relay can be set to remain on during the transient, or provide a pulse ofknown duration. This is configured using the Output Setup Program.

Using the Output Signal



The hardware connection and details of this signal are listed in the Connectors section of this manual.

The side panel of the Processor contains two status lights. The red POWER light will show brightly when theunit is running with sufficient power. If this light is dim, and you are using a battery, the battery is probablyweak. You should charge or replace the battery to reduce the possibility of losing data or not being able toconnect using the PDA.

The Transient Pressure RUN Screen isshown at right.

The occurrence of a transient is shown inreal time, and the details are recorded in afile in the Processor.

Whenever a transient is detected, an outputsignal is generated by the Processor. Thissignal can be used to turn on an alarm bell,a warning light, send a signal to a PLC orSCADA RTU, or anything that uses anON/OFF signal..

LINK Light



The LINK light indicates the status of the WiFi communications. When the Processor is first turned on, the lightwill turn on GREEN for a few seconds and then turn off.

After the WiFi has started, the LINK light has the following meaning:

If you are having trouble communicating with the Processor using the PDA, the LINK light will help youdetermine what is happening.

After installing the hardware, check the system using the Pocket PC PDA.

Note: The Level 1 Module will start communicating in approximately 90 secondsafter power is applied. Please wait a sufficient amount of time.

Monitoring System, you must install the QViewPlus software and WiFi cardon your Pocket PC PDA or laptop computer before performing the stepsbelow.

Turn on the Pocket PC PDA. Press the button on theupper right side of the PDA.

If your PDA has built-in WiFi, be sure that it is turnedon. See the Configuring WiFi page for information onhow to turn it on.

Watch the LINK light on the Processor to see if it hasconnected with the PDA.

The PDA should show that the WiFi is connected to"Qameleon".

Tap on 'Start' to display the Start menu. Tap on'Programs'.



Tap on the 'QViewPlus' icon to start the application.

In the 'Select a Device' screen, tap on the itemDifferential Pressure. Then tap the 'Run' button.



The RUN screen shows the current pressures fromSensor 1 and Sensor 2. It should look similar to thescreen at right.

If your hardware setup is correct, you will see pressurevalues under Sensor 1 and Sensor 2 that correspond tothe actual pressures in PSI where the two pressuretransducers are installed.

Now tap 'Commands' in the lower left of the screen, andtap 'Select a Device'.



Tap 'Transient Pressure (SENSOR 1)' or 'TransientPressure (SENSOR 2)', then tap 'Run'.

If your hardware is set up correctly, the RUN screendisplays the current conditions of the monitor. It maytake one to two minutes before this screen displays theBackground Level and Sample Time, since the monitorneeds to calculate an average pressure value before itdisplays the Background Level.

Note: Occasionally, nearby electrical equipment willintroduce noise into the sensor. Remove anypressure from the sensor, click on STOP andthen GO. Note the Maximum and Minimumvalues. If there is more than 3 PSI difference,you many need to ground the Processor.



Now you are ready to use the Transient Pressure Monitoring System to analyze your pipelines.

To stop the QViewPlus program, tap 'Commands' and'Quit'.

Setting up the Internet Hardware



To use your system over the Internet, you will first need to establish an account with a service provider. If youare using the QWICcell cellular option, you will use CrossBridge Solutions as the service provider. See "SettingUp an Internet Connection" for more details.

The QWICcell cellular system establishes a Virtual Private Network to communicate with the Processors in thefield. This secure system makes your Processors appear to be on your own local network, even though they maybe anywhere in the world. The Processors must have their own unique addresses which are assigned to you bythe network service provider (CrossBridge). These addresses will be set up for you when you purchase theQWICcell unit. However, you can reconfigure them if necessary.

Note: There are many different ways to connect the Processor to the Internet. Theseinclude campus-wide WiFi, DSL, corporate networks, etc. However, they areall similar in setup to the cellular system. Please contact Qameleon Technologyand we will help you with other network configurations.



When you install the Processor, simply connect the cellular antenna to the connector on the lid of the Processor.

The Transient Pressure Monitoring System is a wireless system that continuously monitors the pressurein a pipe and stores this data for later retrieval. It consists of three components, a PDA, a Processor, anda set of Sensors.

You interact with the system using a program called QViewPlus that runs on the PDA, laptop ordesktop. Everything you need to do with the Transient Pressure Monitoring System is done from thisprogram, including checking the current data, setting limits, calibrating the sensors, and retrieving thestored data.

The Processor continuously monitors the pressure in the pipe and stores the data for later retrieval.When you come within communication range of the Processor with a PDA, you are shown a list ofpossible applications that can be run. The you can select one of these, and interact with it as if the PDAwere the control panel. When you move out of range of the Processor, the applications disappear fromthe PDA's list, but the last selected application continues to run in the Processor.

The Transient Pressure Monitoring System is really two instruments that can be selected, configured,and run remotely using the PDA:

the Transient Pressure Monitor, and the Differential Pressure Monitor

Both of these instruments share the same sensors and sensor calibration information. The sensors arecalibrated for both instruments from the CALIBRATE Screen of the Differential Pressure Monitor. Allother settings and parameters are unique for each instrument. This means that these settings must beindividually set for each instrument.

Running the Transient Pressure Monitoring System

Note: This manual will refer to all of the devices that run QViewPlus (PDA, laptop,desktop, etc.) as the PDA, unless there are differences in their operation.

PDA Processor Sensors

Page 1 of 61Running the Transient Pressure Monitoring System

12/23/2016file:///C:/Users/efierro/AppData/Local/Temp/~hhFF57.htm

There are two Transient Pressure Monitors that can be selected individually. An auxiliary applicationstops the current running monitor to allow you to retrieve the stored data. There are two setup programsfor configuring the optional GPS receiver and output signal.

QViewPlus runs on the PDA, and provides the graphical user interface to the Processor.

Use QViewPlus as follows:

Differential Pressure Continuously monitors the two sensors, and displays their current readingon the PDA. The maximum and minimum pressures can be seen, as well asthe dates and times of their occurrences. The readings are also stored in theProcessor for later retrieval. The Differential Pressure application is alsoused to calibrate the sensors.

Transient Pressure Continuously monitors one of the sensors to detect rapidly-occurringtransients. The actual pressure readings from the selected sensor are storedin the Processor for later retrieval. The PDA shows you the currentinformation about the transients, such as the number of events, the date andtime of the last event, and the maximum and minimum pressures that wererecorded during the last transient.

Stop Monitors This is a simple application that stops all the monitors so that the datastored in the Processor can be retrieved.

GPS Setup Enables the optional GPS receiver to precisely set the internal clock of theProcessor. Displays the current GPS coordinates and time while installingthe GPS receiver.

Output Setup Allows the user to configure the output signal that is generated when atransient is detected.

Using QViewPlus

Note: QViewPlus must be installed on your PDA before you can use it. The WiFi must also beconfigured.

Note: There is an alternate version of QViewPlus that is used for accessing the Processor overthe Internet or on a corporate intranet. This version only runs on PCs that have access tothe Internet or the intranet.

- monitoring the input and output of a pressure reduction valve- monitoring the input and output pressures of a pump- comparing two different pipes



Using the Differential Pressure monitor is easy.

If you are using a wireless card in your PDA,such as the D-Link Air card, be sure that it isinserted in the compact flash slot on the PDA,and that its light is flashing, or is oncontinuously.

Differential Pressure RUN Screen

The RUN screen shows the current pressures fromSensor 1 and Sensor 2. The colored bars indicate howthe current pressures compare to the user-set limits.

Between the pressures is a green light that flashes everytime a sensor reading is sent to the PDA (approx. onceper second). If this light is not flashing, you are

probably out of range of the Processor.

Tapping on the red Sensor 1 box will display the historyof the sensor. This shows the maximum and minimumpressures for that sensor, and the times when theyoccurred. This history covers the period from the timethe data was Reset (described below) and the presenttime.

Tapping on the green Sensor 2 box will display thehistory of that sensor. You can alternate between thetwo histories by clicking on the appropriate box. When



you are finished, tap in the white box, and the historybox will be turned off.

The red light on the RUN screen indicates the status ofthe ALERT switch. This can be used for anything, suchas a float switch indicating a flood. When the switch isclosed, the red light will flash and the PDA will sound abeep.

The PDA maintains a file of the current readings andthe history of the sensors. Tapping on the SAVE andRESET button will append the readings from thismonitor to the file for later analysis. This is useful fortracking the readings of the monitors over time. The IDof the monitor is recorded with the readings. Having aunique ID for each monitor allows you to collectreadings from any number of monitors in the same file.



The Differential Pressure Monitor SETUP screen lets you set the parameters of the monitor any timeyou wish. These values set the limits for the sensors, identify this particular monitor, and determine howoften the current readings are recorded in the DPhistory.dat file.

A PC program called ConvertData will later retrieve thefile from the PDA and create a comma-separated-variable (.csv) file which is compatible with mostspreadsheet programs.

Differential Pressure SETUP Screen

The colored bars associated with each sensor indicateshow the current readings compare to the preset limits.

You can set the acceptable pressure limits for thesensors whenever you wish by tapping the SETUPbutton.



The SETUP screen shows the current settings of theDifferential Pressure monitor. You can change theseanytime you wish.Monitor ID: a unique number to identify this

To set one of the values, tap in the box surrounding thevalue.



A keypad will appear that allows you to set the chosenvalue (highlighted in orange). Tap each number, andthen SET to save the value, or CANCEL to keep the oldvalue.

When you are finished setting the values, tap on theRUN button to return to the RUN screen. The valuesyou entered will be saved in the Processor and usedwhenever the monitor is started.



The Differential Pressure Monitor CALIBRATE screen is used to calibrate the sensors for the entireTransient Pressure Monitoring System. You must use this screen to calibrate the sensors even if you areonly going to use the Transient Pressure Monitors. The Processor has its own internal clock which isused for the recordings. You can synchronize the clock in the Processor with the PDA clock using thisscreen.

If you wish to calibrate the sensors, or set the time inthe Processor, tap on the CALIBRATE button.

Differential Pressure CALIBRATE Screen

Note: The sensors that came with your system may have different pressure ranges. They arealready calibrated for their respective locations (connectors) on the Processor.

If you swap Sensor 1 and Sensor 2 between connectors, you will have to recalibrate thesoftware. Use this procedure to calibrate them.

The CALIBRATE screen is used to set theparameters that are used by the whole TransientPressure Monitoring System.

Before using the system, you should synchronizethe clock in the Processor with the PDA. First, setthe time zone and time on the PDA. See themanual that came with your PDA to see how toset its time. Be sure that the time zone is setcorrectly on the PDA, as well as the time. If itis not, the time in the Processor will not be set



correctly.

Once the time zone and time are set on the PDA,simply tap on the Sync. button to synchronize thetime in the Processor with the time on the PDA.

Over time, the clocks may drift apart. It is a goodidea to periodically synchronize them.

If you need to calibrate the sensors, you willneed a gauge that will serve as the standard.(The accuracy of the calibration is dependent onthe user's needs. Having precise calibration maynot be absolutely necessary, since the transientpressure detection is based on relative pressurechanges.)

The gauge should be in the same circuit as thesensor and there should be a way to turn off theflow to the sensor.

For each sensor to be calibrated, turn off the flowto the sensor so that there is no pressure. Thentap on the appropriate ZERO button. This will setthe zero point of the sensor.



You can set the zero point of both sensors, if youwish.

Open the valve to each sensor, and read thepressure on each gauge.

Tap in the box surrounding the NOW value of theparticular sensor.

A keypad will appear that allows you to set thechosen value (highlighted in orange). Tap eachnumber, and then SET to save the value, orCANCEL to keep the old value.



The value you see in the corresponding Now boxshould match the pressure shown on the gauge.

When you are finished setting the values, tap onthe SETUP button to return to the SETUP screen.The values you entered will be saved in theProcessor and used whenever the monitor isstarted.

Note: For precise calibration, you should apply a steady pressure that is near the upper limit ofthe sensor. This will minimize errors in calculating the pressure.

For example, a 500 PSI sensor should be calibrated with at least a 400 PSI referencepressure.



The Transient Pressure monitor is a unique instrument that watches for, and records, the occurrences ofrapid changes in pressure. Transient pressures do not last very long, typically from a few milliseconds toseveral minutes. In most pipelines, the pressure is relatively steady most of the time. The TransientPressure Monitor will detect and record only the transients at a high frequency. Steady-state backgroundpressures will be recorded at a much lower rate. This will preserve records of the transient, while savingyou the time of manually examining extensive, redundant, high-frequency data.

Possible applications of the Transient Pressure monitor include:

The Transient Pressure monitor is very flexible and has a lot of features. Please see the section on "Howthe Transient Pressure Monitor Works".

Transient Pressure RUN Screen



As the Transient Pressure Monitor runs, it writes its data to its corresponding TPdata.dat file.

The RUN screen shows the currently selected sensorand Monitor ID. The ID is used by the QAnalyzeprogram to group together the readings for plotting.You should pick different Monitor IDs for each sensorand for each installation of the Transient PressureMonitoring System.

The Background Level is the current Average pressurefrom the sensor. The Average is determined by theSamples Averaged setting in the SETUP screen.

The Sample Time is the time of the last backgroundaverage reading taken.

On the right side is a green light that flashes every timea background average is sent to the PDA (determinedby the Background Sample Rate). If this light is notflashing, there are three possible reasons:

- The monitor was just started with a new SamplesAveraged setting.

- A transient is in progress and is being recorded.



The Transient Pressure Monitor SETUP screen is used to set the parameters for the way the monitor willrun. Both monitors (SENSOR 1 and SENSOR 2) work in exactly the same way. However, each monitorhas its own settings.

The Transient Pressure Monitor is a unique instrument that watches for, and records, the occurrences ofrapid changes in pressure. Transient pressures do not last very long, from a few milliseconds to severalseconds. Most of the time, the pressure is relatively steady.

Transient pressures can occur in a pipe at any time. They can be caused by a number of events, such aspumps turning on and off, valves opening and closing, and power failures. It is a tedious task tocontinually watch the pressure in a pipe for transients, since they occur very fast, and not very often.

Recording these transient pressures with a computer is a matter of taking samples of the pressure atknown points in time. The number and rate of sampling affects how long you can monitor the pipe.

Once the samples are recorded they must be examined to find the transients. It can take a long time for aperson to perform this task. The Transient Pressure Monitoring System can identify the transientsautomatically.

The Monitor can be tailored to different situations by using the SETUP screen and setting the operatingparameters. The following pages explain what the settings do:

How the Transient Pressure Monitor Works

- Sampling and Recording

- Background vs. Transients

- Background Averaging

- Automatic Transient Recording

- Manual Transient Recording



Recording transient pressures with a computer is a matter of taking samples of the pressure at knownpoints in time, and then storing them in a file. The number of samples and the rate at which they aremeasured affects how long you can monitor the pipe. Any pressure recorder is limited by how muchmemory is has. The total number of samples that can be stored determines the usefulness of the monitor.

Sampling and Recording

Sampling is the process oftaking a single reading fromthe sensor. The sample ratedetermines both the accuracyof the recording and theamount of data you mustrecord.

The RED dots represent a fastsample rate. The GREEN dotsrepresent a slow sample rate,10 times longer.

High Frequency sampling(fast) captures most of thedetails of the pressure signal.However, it generates a lot ofdata. Sometimes a slower rateis good enough to capture the"look" of the transient.

A slower sampling rategenerates a lot less data, butcan miss the details of thetransients entirely.

The Transient PressureMonitor always samplesvery fast to detect transients.When a transient is detected,it records the pressure at theHigh Frequency rate. Afterthe transient is finished, itrecords at a slowerBackground Rate. This allowsyou to run for a long timewithout filling up the



The pressures in pipes are never constant. They rise and fall over time due to many factors, such as thedemand or the number of pumps operating. This is normal. So when a transient occurs, we need todistinguish it from the normal pressure variations in the pipe. This is not always an easy task.

The Transient Pressure Monitor detects the rapid change in pressure from the normal background level.So it is important to establish what the "Background Level" is. This is described in the next section,Background Averaging.

monitor's memory, and makesfinding transients in the datavery easy.

The Transient Pressure SETUP screen allow you tochange the High Frequency rate for recording thetransients, and the Background Record Rate forrecording the background readings.

Background vs. Transients

Some transients are easy todistinguish, such as the onesshown in RED. Sometimesthe background is easy to tellalso.

There are many times when itis not easy to tell. Are weseeing a slow transient, or justa normal change in thebackground pressure?



The Transient Pressure Monitor detects the rapid change in pressure from the normal background level.So it is important to establish what the "Background Level" is. The Transient Pressure SETUP Screenhas settings for determining the Background Level of the pipe.

The Background Level is the average pressure in the pipe measured at a fixed rate. Calculating a good,representative average is a matter of selecting the rate at which the samples will be included in thecalculation, and the number of samples considered.

Background Averaging

The Transient PressureMonitor always samples veryfast to detect transients.However you do not want touse all of these readings todetermine the BackgroundLevel, since it will take a longtime and result in a level thatmay not reflect the current"normal" pressure in the pipe.

The two factors thatdetermine the average are theBackground Sample Rateand the number of SamplesAveraged.

The Background SampleRate determines how oftenthe background average iscalculated. If it is too fast, it issusceptible to minor changes.If it is too slow, it will notkeep up with the current stateof the pipe.

Setting this rate is often a trialand error process.

The default setting to theProcessor as delivered to youis 50 mSec, or 20 times persecond.

The number of SamplesAveraged determines howsensitive the BackgroundLevel is to changes in the



The Transient Pressure Monitor detects the rapid change in pressure from the normal background level.So it is important to establish what "rapid" means and what is considered a significant change.

The Transient Pressure SETUP Screen has settings for determining the start and end of a transient.

Automatic transient detection is based on the Threshold for the change from the Background Level and

pressure. In other words, whatis considered the "normal"pressure in the pipe at anygiven time.

Averaging a lot of samplescauses the average to changemore slowly, and makestransients stand out, but canidentify transients that are notreally there. Averaging toofew samples may miss thetransients.

The default setting to theProcessor as delivered to youis 100 samples. You canadjust this as needed..

The Transient Pressure SETUP screen allows you tochange the Background Sample Rate forspecifying when to include a pressure reading in theaverage Background Level. You can also change thenumber of Samples Averaged when determiningthe background.

Other settings are used to automatically recordtransients and to manually control the recording oftransients.

Automatic Transient Recording



the Absolute Difference of the sample from the background level.

The START Threshold andthe STOP Thresholdrepresent the amount that asample can deviate from theBackground Level and not beidentified as a transient. (Thisis actually the StandardDeviation from theBackground Level x10. Butyou can think of it as arelative number.)

When a sample deviates fromthe Background Level bymore than the Start Threshold,the monitor starts recording itas a transient, shown inPURPLE.

When the sample deviates lessthen the STOP Threshold, themonitor terminates thetransient and records onlybackground readings, shownin BLUE.

The STOP Threshold is oftenset lower than the STARTThreshold, to ensure that theentire transient is recorded.

Because these thresholds arebased on standard deviation,their absolute value variesaccording to the amount ofvariation in the actual pressuredata. When the pressurevalues are stable, the standarddeviation is small. When thepressure is changing, thestandard deviation is large.

Determining the Thresholdlevels is often a trial and errorprocess.

Note:

The START and STOP Thresholds are shown asrectangles. This is because they are calculated onlywhen the Background Level is determined. Thishappens less often than the actual pressure sampling,and stays in effect until the background average iscalculated again.

Sometimes the pressure isquite stable, and has little



variation. In this case theThresholds represent verysmall deviations from theBackground Level.

This makes the TransientPressure monitor verysensitive, and it may detect atransient when it is actuallyjust an insignificant change.

The Absolute Difference isused in conjunction with theThresholds to ensure that thesample actually varies enoughfrom the Background level tobe called a transient. TheAbsolute Difference is thedifference between a pressurevalue and the BackgroundLevel.

To qualify as a transient, thesample must deviate from theBackground Level by morethan the Start Threshold and itmust deviate by at least theAbsolute Difference.

When the sample deviates lessthan the STOP Threshold andless then the AbsoluteDifference, the monitorterminates the transient.

In this example, the points atA do not meet bothconditions,. The points at B domeet them, and a transient,shown in PURPLE, isrecorded.

Note:

If the START Threshold is set to 0, only theAbsolute Difference will be used to trigger thetransient recording.

If the STOP Threshold is set to 0, the sample willhave to equal the Background Level EXACTLYbefore the transient recording will stop. It is not agood idea to set the STOP Threshold to 0.

The Transient Pressure SETUP screen allow you to



The Transient Pressure Monitor detects the rapid change in pressure from the normal background level.The monitor can detect the start and end of a transient automatically, or you can manually control thisprocess.

Transients are shown in PURPLE in the following illustrations.

specify that transient recording will START andSTOP Automatically.

The Threshold and the Absolute Difference specifywhen a change is rapid and significant.

You can also manually specify when a transient isrecorded.

Manual Transient Recording

The Transient Pressure SETUP screen allows you tospecify how the recording will START and STOP.

You can specify Manual or Automatic separatelyfor starting and stopping the recording.

The Manual Record Time specifies how long therecording process will last when Manual STOP ischecked.



START RECORD =Automatic

STOP RECORD =Automatic

The monitor automaticallydetects and starts recordingtransients. It stops recordingautomatically, when thestopping conditions are met.

START RECORD =Automatic

STOP RECORD = Manual

In this case, whenever themonitor automatically detectsand starts recording atransient, it will stop recordingafter the Manual RecordTime has elapsed.

START RECORD =Manual

STOP RECORD = Manual

This allows manual recordingof data from the sensor at theHigh Frequency rate.

The recording starts as soon asthe RUN button is tapped onthe Transient Pressure RUNScreen. The recording stopsafter the Manual RecordTime has elapsed.



The Transient Pressure Monitor can be used in many different situations. The choice of the settings areoften best determined by trial and error.

Here are some recommended starting settings for different situations:

Only 1 transient is recorded.

START RECORD =Manual

STOP RECORD =Automatic

In this case, the recordingstarts as soon as the RUNbutton is tapped, but stopsalmost immediately, since thepressure readings are alreadybelow the STOP Threshold.

This combination is notuseful. In most cases, theresults will beunpredictable.

Retrieving the Data Files

Monitor File name Description



When Switch 3 inside the box is set to 'OFF' (see diagram below), the Transient Pressure Monitor has 3single data files as shown in the table above.

When Switch 3 is set to 'ON', a new data file for each of the 3 types is created every day. This keeps thesize of the individual data files relatively small, which is important if the wireless connection is slow orexpensive. The file names contain the date at the beginning of the name, for example: 2009-07-21-PTD_Sensor_1_data.dat

When Switch 4 is set to 'ON', deleted data files are actually moved to a folder named 'Backup' on theLevel 1 Module, rather than being deleted. This is called the 'Hidden Backup' feature.

Differential Pressure DPhistory.dat Settings, current readings, and statistics,recorded at user-specified intervals.

Transient Pressure(SENSOR 1) PTD_Sensor_1_data.dat

Settings, background averages, fulltransient data, recorded as specified byuser.



Note: The Level 1 module stores its data on a USB memory "flash drive" located on the maincircuit board. The Level 1 Module has 1GByte of memory or more available for data,allowing the unit to record for a very long time. However, this will take a long time toupload using the PDA. If you are using the QWICcell cellular option, this will be veryexpensive. You may wish to remove the USB memory from the Level 1 unit and copy thefiles directly to your PC. Instructions for doing this are in the "Accessing the USBMemory" memory section of the manual.



Retrieving Single Data Files

Select the monitor whose files you wish toupload. In this case, select "DifferentialPressure", and then tap on the Files button.

You will see a list of the files that are associatedwith that monitor. Select the .dat file, and tap onUpload.

Note that there may be a file called ErrorFile.txt.In the unlikely event that the Processor has anerror, it will write a message to this file. Uploadthe file, and read it in a text editor. Please contactQameleon Technology if this happens.

If the file is preceded by "Cannot read the file ",it means that either the Processor is performingsome action on the file that cannot be interrupted,or the file has not yet been created. Stop themonitor if necessary, and try again.

You can name the uploaded file anything that youwish. Tap the filename, and use the keyboard tochange it to the name that you want. In theexample at right, the uploaded file will be named'DPhistory 6-10'. The 'Type:' field shows whatwill be appended to the end of the name, in thiscase, '.dat'. The final file name will be 'DPhistory6-10.dat'.



The file will be stored in the '\My Documents'folder on the PDA. If you would like to have itstored elsewhere, use the pull-down list in the'Folder:' field to select another location. In thisexample, the file will be stored in the '\MyDocuments\Business' folder.

Finally, click OK. After a short delay, the filewill be stored on the PDA.

As the monitors run, they append their new datato the existing data (.dat) files on the Processor.After uploading a file, it is a good idea to deleteit, and start over with an empty file.

Select the monitor, and tap on the Files button.

Select the file you wish to delete, and then tap onthe Delete button.



Stopping the Monitors

If you see the text "Cannot read the file ..." in the QView window, it means that the file either has notbeen created yet, or that the monitor is currently writing to the file. Wait a few seconds and then tryagain.

The Monitors lock their data files when they are writing to the files. This can occur if you have specifiedthat the files be written at short time intervals. You need to stop the monitors first. Do the following:

You will be asked to confirm the deleteoperation. Tap Yes to delete the file, or No tokeep it on the Processor.



From the selection screen, select "EmergencyStop for Monitors", and tap on the Run button.

When the red screen appears, tap on Commands.

Tap on Select a Device.



Follow the steps above to retrieve the data filesthat you want.

Do not forget to restart a monitor when youare finished uploading the files. Select the



Retrieving Daily Data Files

monitor you want, and tap the RUN button.

From the 'Select a Device' screen, select'Transient Pressure (SENSOR 1)', and then tapthe 'Files' button.

You will see the 'PTD_Sensor_1_data.dat' file.Select it, and tap the 'Upload' button.

Note that there may be a file called ErrorFile.txt.In the unlikely event that the Processor has an



error, it will write a message to this file. Uploadthe file, and read it in a text editor. Please contactQameleon Technology if this happens.

If the file is preceded by "Cannot read the file ",it means that either the Processor is performingsome action on the file that cannot be interrupted,or the file has not yet been created. Wait aminute, and then try again.

QView will tell you first and last dates on whichit has a data file of the type you selected.

Now, you must specify the first and last file datesthat you want to upload. (QView will upload thefiles from those dates, as well as all the dates inbetween.)

Tap the box to the right of 'Start Date'.

A calendar appears, with the first file datehighlighted. Select the starting date for fileupload, then tap the 'OK' button.



Repeat for the 'End Date'.

Select the 'OK' button.

QView will tell you the number of files and thetotal number of bytes that will be uploaded. Ifyou want to continue with the upload, select the



'Yes' button.

Select the 'Begin Upload' button.

As QView uploads the files, it shows you thename of the file currently being uploaded, and aprogress bar that indicates how much of the filehas been uploaded so far.

The files are stored in the 'DailyFiles' folder onyour PDA. If you are running QView on a PC,



You can use QViewPlus on your laptop or desktop PC to provide the graphical user interface to theProcessor. You must use this version of QViewPlus if you are connecting to the Processor over theInternet.

you specify the folder where the files are storedusing the 'Options' feature.

Hidden Backup Files

If the Hidden Backup feature is enabled, files that are deleted will actually be moved to abackup directory on the Transient Pressure Monitor rather than being deleted. You cannotaccess these files using Transient Pressure Monitor. Because the available flash memory isso large (at least 1 Gb), storing all of these files should not fill up the memory, undernormal conditions.

To enable the Hidden Backup feature, set switch 4 inside the Transient Pressure Monitorto 'ON'.

If you want to retrieve these files, or if the flash memory is full and you want to delete thefiles, do one of the following:

Remove the USB memory card from the Transient Pressure Monitor. Plug it in toany Windows PC, and use File Explorer to access the 'Backup' directory.

Use FTP to access the 'Backup' directory on the Transient Pressure Monitor.

The Data Analysis programs run on your PC (desktop or laptop). They convert the data recorded by theProcessor or PDA (or PC) into a form you can use.

The Processor saves data from the Differential Pressure monitor and the Transient Pressure monitor intheir own data files. You retrieve these files from the Processor by using QViewPlus on your PDA orPC. The data analysis programs, QAnalyze and ConvertData, run on your laptop or desktop PC. Theyupload the data files from your PDA to your PC, and convert the data to a form that you can use. (If youare using QViewPlus on a laptop or desktop PC to retrieve the data files from the Processor, QAnalyzeand ConvertData can be used to convert the data directly.)

Using the ConvertData Program

Database Format

The QAnalyze program runs on your PC, and provides a graphical interface to the data collected by theTransient Pressure program on the Processor.

QAnalyze

Start QAnalyze: From the 'Start' menu in the lower left of your PC screen, select 'Programs','Qameleon', 'QAnalyze', 'Launch QAnalyze.exe'.



With the QAnalyze program, you can:

Read the data file from your PDA or PC and store the data in a database; Graph the transient pressure data; Record details of the Processor (monitor) installation.

If you are using a PDA:

If you are NOT using a PDA:

The Processorrecordspressure data ina file.

WiFi

You use QViewPlus onthe PDA to upload thedata file from theProcessor to the PDA.

ActiveSync

QAnalyze reads the datafile from the PDA, storesthe data in a database,and graphs the data.



The QAnalyze program has many options that let you graph and examine the data.

The QAnalyze Database

QAnalyze reads the data files that are created by the Processor, and stores the data in a database. Thedatabase format is that of a Microsoft Access database, and the database file ends with a ".mdb" fileextension. You do not need Microsoft Access installed on your PC to use QAnalyze. If you do haveMicrosoft Access installed, you can use it to view and analyze the database.

The data in the database includes:

Time and pressure data points, labeled as to whether they were collected in background ortransient mode.

Parameter settings on the Processor, with start and end times Monitor installation details. A Monitor corresponds to the Monitor ID that you entered on the

Setup screen of the Transient Pressure program. You enter the Monitor installation details intoQAnalyze, including items such as date and location of the installation.

Recommendations for using QAnalyze:

The Processorrecords pressuredata in a file.

WiFior

Wired LAN

You use QViewPlus on your laptop or desktopPC to upload the data file from the Processorto the PC. QAnalyze reads the data file, storesthe data in a database, and graphs the data.

Keep databasessmall

As the database grows, it takes longer to record new data, and toretrieve and graph data. It is a good idea to create separate databaseswhen possible; for example, for each installation location, or for eachMonitor ID.

Save the sourcedata files

If your database becomes corrupted in some way, QAnalyze will notbe able to read it or create graphs. Also, once you read a data file intoQAnalyze, it is not possible to "undo" it, or delete that data from thedatabase. In these cases, it is best to recreate the database by usingQAnalyze to read the original data files.

Do not modifythe databasestructure

The database tables have a specific structure that QAnalyze expects. Ifyou use Microsoft Access to view the data, it is possible to change thestructure of these tables. DO NOT DO THIS! Specifically, do notadd or delete any columns in the tables, and do not change any datatypes. You may modify specific data values in the tables. You mayalso delete entire records from the tables, or add new records.



The QAnalyze program builds a database of all of the Transient Pressure data on your PC.

Creating a new Database:

Creating and Accessing Databases in QAnalyze

To create a new database, click on the 'SelectDatabase' item in the 'File' menu.

In the File Opendialog box, go to thefolder where youwish to store thenew database. Typein the new databasename in the 'Filename:' field, thenclick the 'Open'button.



Accessing an Existing Database:

Once you have created or selected an existing database, QAnalyze will continue to use that databaseuntil you create or select a different database.

To access an existing database, click on the 'SelectDatabase' item in the 'File' menu.

In the File Opendialog box, go to thefolder where theexisting database isstored. Click on theexisting databasename to select it,then click the 'Open'button.



You can use QAnalyze to read a Transient Pressure data file in any of the following ways:

When QAnalyze has finished reading the datafile and storing it in the database, it will ask ifyou would like to view a graph of the data thatwas just read. Click on 'Yes' to view the graph,otherwise 'No'.



QAnalyze will create graphs of pressure vs. time. When you read in a new data file, QAnalyze will plota graph of that new data if you desire. At any time, you can create a graph of any pressure data thatexists in the database.

To create a graph:

Graphing Data using QAnalyze

Select 'New Graph' from the 'File' menu.

The 'Graph Data' dialog box appears. Thislets you select the Monitor ID and timerange for the data you wish to graph.Graphs may only be created for oneMonitor ID at a time. It is not possible tocreate a single graph showing two MonitorIDs using QAnalyze.

Notice the text at the upper right. Thisshows the range of dates and times forpressure data for Monitor ID 174 in thisdatabase. Notice that the date and time inthis example is given in GMT (GreenwichMean Time). You can switch betweenGMT and Local time, where Local time isthe time zone of your PC. We will seehow to switch later on this page.



Notice that in this Graph Data dialog, weselected Monitor ID 174, Start time ofJune 3, 2004 at 17:52:00 GMT, End timeof June 3, 2004 at 17:53:59 GMT.

Click on the 'GRAPH' button, andQAnalyze will extract the pressure datafrom the database, and plot the graph.

This is the graph that QAnalyze plots for the selections above.

Notice that the background data is plotted in blue, and the transient data is plotted in red.

Notice the gaps in the graph. Gaps occur whenever the Transient Pressure program isstopped on the Processor. This happens every time the parameters are changed orchecked by the user, and every time the files are uploaded.



To zoom in on a portion of this graph:

Position the cursor at the left edge of the area you wish to view. Hold down the left mouse button and drag the mouse to the right. A purple dashed

line will be drawn around the area you have selected. Release the mouse buttonwhen you have reached the right edge of the area.

Position the cursor inside the purple box. Click the right mouse button. A menu will appear. Select 'Graph'.



QAnalyze zooms in on the graph, drawing it as shown below.

If you wish to see the individual data points:

Move the cursor anywhere over the graph. Click the right mouse button. A menu appears. Select 'Show Points'.

QAnalyze plots the individual data points on the graph, as shown below.



There are two options that you can set for the graphs:

The pressure range to be plotted. GMT vs. Local time

To set these options, select 'Options' from the 'View'menu.

Selecting 'Options' causes the 'Options' dialog to be displayed.

In the example below, notice that there are two selections for the 'Pressure Range inGraphs':

Automatic - QAnalyze automatically selects the pressure range so that all of theselected data is visible in the graph.

Limits - QAnalyze uses the specified maximum and minimum to define thepressure range that is plotted. Some of the selected data may not be visible in thegraph.

In the example below, we are setting the pressure range to 30-104 PSI.



When you click the 'OK' button, the graph is redrawn to have the specified pressure range.

This pressure range will be used by QAnalyze for all subsequent graphs, until youchange it to a different range, or sets the option to 'Automatic'.



The other option that can beset is the selection of GMT(Greenwich Mean Time) orLocal Time for graphs. LocalTime is the time zone of thePC. For example, in Arizona,Local Time is GMT minus 7hours.

Clicking on the "What isthis?" buttons will display anexplanation of the time zones.

When you switch betweenGMT and Local Time, thecurrent graph is not redrawnwith the new times, but allsubsequent graphs are drawnusing the new selection (GMTor Local). Also, the timeranges in the 'Graph Data'dialog and the 'ParameterSettings' dialog are shown inthe new selection.

Note:

"GMT" stands for Greenwich Mean Time. This is the time zone for Greenwich,England. GMT is universally considered to be time zone 0. All other time zonesare expressed relative to GMT.

This program stores all times in the database using the time zone of GMT. In otherwords, the time of a data point in the database is the time that it was in Greenwich,England, when that data point was collected.

"Local Time" is the local time zone of this computer. When displaying the graphs,the program takes the time of each data point, which is stored in the databaseusing the GMT time zone, and applies the time zone correction factor for the timezone of this computer. This is NOT the local time zone where the data wascollected, but rather the local time zone of the computer you are currently using.

Here, the last graph shown above is drawn again using Arizona local time.

Notice that all of the times on the graph are 7 hours earlier than in the previous GMTgraph.



QAnalyze stores the parameter settings that were current in the Transient Pressure program when thedata was collected.

After you have drawn afew graphs, use the'Window' menu toarrange them. You canCascade or Tile them inthe QAnalyze mainwindow. You can alsoselect one of them fromthe list of windows (eachgraph is in a separatewindow).

Viewing Parameter Data in QAnalyze

To show the parameters:

Place the cursor over the point on the graph that you wish to see. Click the right mouse button. A menu appears. Select show parameters.



When QAnalyze reads the first data file containing a specific Monitor ID, it asks you to enter

QAnalyze displays theparameters that were current atthat time for that Monitor ID.

Notice that the time is shown ineither GMT or Local Time,depending on the currentOptions setting.

Click the 'OK' button when youhave finished viewing theparameters.

The Transient Pressure Monitoring System creates a lot of data that you can analyze. The easiest way tolook at the Transient Pressure monitor data is using the QAnalyze program. However, the data from theDifferential Pressure monitor is best viewed using a spreadsheet program like Microsoft Excel.

The monitors store their data files in a format that is very compact to save memory, but is difficult toexamine. The ConvertData program converts the data files to comma-separated variable (.csv) files,which can be viewed in Microsoft Excel. The program converts data files from both the DifferentialPressure and Transient Pressure monitors running on the Processor.

You only need to run this program if you want to look at the data in the four files listed below in aspreadsheet. The conversion can be applied to any of the files that you wish.

Once you have the data in the .csv format, you can use the spreadsheet to generate reports, create graphs,or perform your own calculations.

The ConvertData program will process any of the .dat files produced by the system.

The ConvertData program automatically determines the type of data file it is processing.

StartConvertData:From the 'Start'menu in thelower left ofyour PC screen,select'Programs','Qameleon','ConvertData','LaunchConvertData.exe'

This screen appears when you run theConvertData program.

If this is the first time that you haverun the program, you have to specifywhich files to convert. Click on the'Setup' button.

In the Setup screen, you must firstspecify the source data file. There are3 options, specified by the small round"radio buttons" inside the red box atright:

1. Copy the data file from the PDA .



to the PC, leaving the data fileon the PDA, then convert it.

2. Copy the data file from the PDAto the PC, and delete the datafile on the PDA, then convert it.

3. The data file is already on thePC. Convert it.

In this screen, we select Option 1, andclick the 'Browse' button to find thefile on the PDA.

This is the file dialog box for thePDA. Find the file name, click on it,then click the 'OK' button.



Next, specify the location and namefor the data file on the PC.ConvertData will copy the file fromthe PDA to this location and filename.

Option 2 does the same thing asOption 1: it copies the data file fromthe PDA to the PC before processingit. But Option 2 then deletes the filefrom the PDA.

Networks



The Level 1 Module (Processor) supports both a wired LAN and a WiFi wireless LAN. It can be set to either use fixed IPaddresses or receive IP addresses from a DHCP server for each network The wireless LAN has a specific name (SSID). Youcan change these settings to match your existing networks, by changing the "RegConfig.txt" file on the Level 1 Module.

In addition, the Level 1 Module can support an optional Machine Room Monitor (MRM) on its WiFi wireless LAN. Adding aMRM to the WiFi LAN imposes some restrictions on that LAN. Specifically, the Level 1 Module cannot be set to receive IPaddresses from a DHCP server on its wireless LAN. In other words, when using a MRM, the IP address of the Level 1 Moduleon the wireless LAN must be a fixed address.

The table below lists the available settings for the wired and WiFi wireless LANs.

The Level 1 Module will alternately try to connect to PCs or PDAs on both the Wired LAN and the WiFi network.

The additional parameters for the WiFi network are as follows:

See the section on Configuring WiFi on your PDA for more information.

The Level 1 Module can be used with a wired LAN as well as with the wireless network. (You will need to install QViewPlus on

must use the same SSID.

If using a Machine Room Monitor, this name mustconsist of ASCII (single byte) characters only.

Network name (SSID)

Qameleon The SSID must be identical to the SSID of the Level1 Module. Contact Qameleon Technology forinstructions on setting this value.

Important: All Level 1 Modules, Machine Room Monitors, PDAs, and PCs within range of each other must haveunique IP addresses. If the IP addresses are assigned by a DHCP server, they will be unique. If youset fixed IP addresses on the devices, you must ensure that they are unique. REMEMBER that the IPaddress of the Machine Room Monitor is 1 greater than the IP address of the Level 1 Module. Do notassign that IP address to another device.

The factory settings for the fixed IP addresses and Subnet Masks are listed on the card included withthe Processor. The fixed WiFi IP address for the Processor will be in the range of 192.94.148.2 to192.94.148.254. The fixed wired LAN IP address for the Processor will be 192.94.147.100.

Note: The Wired LAN and the WiFi network must have different network addresses. For the default factory valuesshown in the table above, the wired network address is 192.94.147.nnn and the wireless network address is192.94.148.nnn. You can use any two network addresses that you wish, as long as they are different.

Network Name (SSID): Qameleon

Network Type: '802.11 Ad-Hoc'

Connecting the Wired LAN



any PCs you wish to use.)

The Level 1 Module has a wired LAN connector inside its enclosure. Remove the four screws holding the cover in place.

(If your Level 1 module has the External LAN Connector Option, simply connect the cable.)


Important: The locking tab on the LAN cable will be facing downward towardthe main circuit board. To remove it, TURN OFF THE POWER first.You may need to use a paper clip or a loop of wire to depress thelocking tab.

For direct connection to a PC,plug one end of a LAN cableinto the wired LAN connectoron the Level 1 module. Plug theother end into the Ethernetadapter on the PC.

You can also plug the cableinto a hub on an existing LAN.



The Level 1 Module uses fixed IP addresses by default. If your network requires different addresses or settings, follow theinstruction in the section called Changing the Network Settings.

The Level 1 Module has both a Telnet server and an FTP server. These are common programs that can be used to configure andmaintain the system. They provide external access to the operating system in the Level 1 Module.

You can use either the wired LAN or the WiFi network to access the operating system. To use the WiFi network, you will needto use a laptop or desktop PC with a WiFi card or built-in WiFi configured as described earlier.

Enabling System Access

You can also disable the Telnet and FTP servers to prevent unauthorized access to the operating system. This is done by settingSwitch 1 on the Level 1 Module main circuit board to its OFF position. The switch is located on the main circuit board betweenthe ribbon cable connectors. You can use a pen or other object to set the switch.

The switch setting takes affect when the system is restarted.

Telnet

The Telnet program allows you to use a PC as a console to the Level 1 Module's operating system. This is similar to the"Command Prompt" on Windows, and accepts most of the same commands. There are only a few functions that you canperform, but it is useful for configuration and troubleshooting.

The telnet program is included with the Windows operating system on your PC.

Using Telnet and FTP

Note: The Level 1 Module will start communicating in approximately 60 seconds after power is applied. Please wait asufficient amount of time before using Telnet or FTP.




When the window appears, type "open nnn", where nnn = the IP address (WiFi or wired) of the Level 1 Module.

The Level 1 Module accepts most of the commands that are used in the "Command Prompt" on Windows. Some of them arelisted below, as well as some additional commands that are exclusive to the Level 1 Module.

It is easier to manipulate files using FTP instead of Telnet.

The directories and files of the Level 1 Module are listed on the Files page.

FTP

cd Change directory.

dir Lists the files in the current directory.

exit quits Telnet

help displays all of the available standard commands

ps Lists currently running processes. (look for pm05.exe)

setGMT Sets the date and time of the system. Uses GMT.

type filename displays the contents of a text file

Important: Do not use the Telnet "date" or "time" commands, since the timezone setting may not match your local time. Use "setGMT" instead.



FTP allows you to transfer files between a PC and the Level 1 Module. You can use any FTP program you wish. The exampleshown here is WS_FTP95.exe.

Click on the Connect button. Configure the FTP connection with the IP address of the Level 1 Module. Use the appropriateaddress for the wired LAN or the WiFi network. You will use an "anonymous" User ID. The password is ignored, and can beanything. Then click OK to connect to the Level 1 Module.

The FTP commands are shown in the picture above. You should consult the instructions for your particular FTP program. Themost common use of FTP is to copy the data and error files from the Level 1 Module to the PC. However, it is much easier toretrieve these files from the Processor using QViewPlus.



The Level 1 Module (Processor) supports both a wired LAN and a WiFi wireless LAN. It can be set to either use fixed IPaddresses or receive IP addresses from a DHCP server for each network. You can set it to adhoc or infrastructure mode. Thewireless LAN has a specific name (SSID), and it also supports encryption. You can change all of these settings to match yourexisting networks, by changing the values in the file "RegConfig.txt".

Please see the "Networks" section to view the rules for network addressing and the current settings of this Level 1 Module.

The standard network IP addresses are arranged in different classes, each with their own default subnet masks. The rules fornetwork addresses are as follows:

Other addresses can be used in special cases. Please check with your network administrator before assigning IP addresses oncorporate networks.

Encryption Settings for Wi-Fi

The Level 1 Module's Wi-Fi can be set to have no encryption, WPA-PSK with TKIP, or WPA2-PSK with AES (also calledCCMP). The latter two options are personal mode, and need a pre-shared key (also called a pass phrase). The key must be 8 to 63characters long. A key containing at least 13 characters is recommended for better security. The characters can be any printablealphanumeric character or symbol, including spaces. The same key must be entered into your PDA's Wi-Fi settings (or any otherWi-Fi device that you are using with the Level 1 Module). The Machine Room Monitor only supports no encryption or WPA-PSK with TKIP, so only use these options if you have a MSM.

Changing the Network Addressing

To change the network addressing in the Level 1 Module, you must modify the "RegConfig.txt" file on the USB flash drive.Remove the USB flash drive from the Level 1 Module, as described in "Accessing the USB Memory", and plug it into your PC.You will find the file "RegConfig.txt" in the "NVRAM" folder on the USB flash drive. Edit it using a text editor. It may be eitherASCII or Unicode. Modify it to contain your desired settings.

The file contains one setting per line, as shown in the tables below. The settings can occur in any order. A tag at the beginning ofthe line identifies the setting. Each tag must appear exactly as shown in the table below, all caps, followed by a colon (:). Thecolon may be followed by any number of spaces, including 0 spaces. After the spaces, type your setting value, followed by areturn. If there is more than one entry containing a particular tag, the Level 1 Module will use the last setting. The only exceptionto this is the "EMAIL RECIPIENT" tag. There may be as many as 10 valid email recipients.

When you are finished editing the file, return the USB flash drive to the Level 1 Module.

Important: Do not delete the QWIC directory, or any of the files contained in it. These are essential for the system.Also, do not delete any of the setup files.

The control program has a "watchdog timer" that restarts the system in case of an error. If you deletethe QWIC files, it will cause the system to restart every 2 minutes. If this happens, please contactQameleon Technology.

If you prefer not to remove the USB flash drive from the Level 1 Module, you may use FTP to transfer the "RegConfig.txt" fileto your PC for editing, then transfer it back when done. When you connect to the Level 1 Module using FTP, you will find the"RegConfig.txt" file in the folder "\Hard Disk\NVRAM".

The following table shows the tags, example settings, and a description of the setting.

Following is a sample "RegConfig.txt" file:

After you have modified the "RegConfig.txt" file, reboot the Level 1 Module.

If you have a Machine Room Module (MRM), the SSID must contain ASCII characters only (1 byte per character). These arethe standard English characters. Please contact Qameleon Technology for instructions on how to change the SSID on yourMRM.

The easiest way to set up an Internet connection to a Level 1 Module (Processor) is to use cellular communication. You can orderthe Level 1 Module with a built-in EDGE cellular modem, configured to use the AT&T cellular data network. You then set up acontract with CrossBridge Solutions for air time (www.crossbridgesolutions.com). CrossBridge Solutions resells AT&T cellulardata service, and also provides a secure Virtual Private Network over the Internet from your PC to the Level 1 Module. Thediagram below illustrates the cellular connection. Please contact Qameleon Technology for assistance in setting up the contractwith CrossBridge Solutions.

Setting Up an Internet Connection



You will use QViewPlus on a PC to communicate with the Level 1 Module over the Internet. See the topic 'Using QViewPlus onthe Internet' to make this work. The PC that you use must have a connection to the Internet.

You can also connect the Level 1 Module to the Internet using a different type of modem, such as DSL or cable, or through alocal area network that has a server or modem connection to the Internet. This must be done by an experienced computernetworking professional. To do this, they need to know the following:

You will need the external LAN connector option on the Level 1 Module.

If you need to modify the Ethernet IP addresses on the Level 1 Module, modify the 'RegConfig.txt' file.

The Level 1 Module uses port 49999 to communicate with QViewPlus. Use port forwarding on the modem or server tosend messages to the Level 1 Module through port 49999.

If you have two or more Level 1 Modules to connect through the modem or server, assign each of them a different portnumber on the Internet side of the modem or server. Use port forwarding to map those port numbers to the LAN side IPaddresses and port 49999 of the specific modules. Enter the Internet-side port numbers when configuring QViewPlus.

You will need a fixed IP address on the Internet side of the modem or server that connects the Level 1 Module to theInternet. This IP address is used to configure QViewPlus so that it can connect to the Level 1 Module.

The Level 1 Module stores its setup, configuration, and data files on a USB flash drive. It uses only 3 directories:

Files



The user data files are:

hard disk\NVRAM The main directory directory for the USB flash memory. This iswhere the setup parameters for the Transient Pressure MonitoringSystem are written. Look for the following files after the programsare run the first time. Not all of these files will be present. You shouldnot try to change these files, since they are managed by the programs.

GPSsetup.dat Contains the setup information for theGPS option.

Options.dat Contains information about purchasedoptions for this unit.

OutputSetup.dat Contains the setup information for theoutput signal.

PRVcalibrate.dat Contains the sensor calibration datafor the Transient Pressure MonitoringSystem.

The Processor is protected against connecting the power cable in reverse. No permanent damage to the unit will result from thisaction, but it will be necessary to replace the fuse.

You must use the following fuse: 2AG 1Amp fast-acting

The Processor stores all of its programs and user data on a USB flash drive. This is a standard memory module that can be readby any Windows PC. If you have collected a lot of data, you may want to remove the memory and copy the data directly to yourPC, rather than uploading it from QView. This is especially useful if you are using the QWICcell, cellular option, since you willbe paying for each byte you transfer.

(SENSOR 1) PTD_Sensor_1_data.dat transient data, recorded as specified byuser.



Replacing the Fuse


Remove the 4 screwsholding the cover in place.The fuse is located at thecorner of the main circuitboard.

Remove the fuse by pryingit out of its clips. Replacethe fuse, and replace thecover.

Accessing the USB Memory


Remove the 4 screws



When you insert the USB memory into a USB socket on your PC, a window will open and you can manipulate the files usingWindows. The user data is located in the following folder:

\Hard Disk\NVRAM

The user data files are listed on the Files page.

If the Hidden Backup option is enabled, there will also be a backup folder at

\Hard Disk\NVRAM\Backup

The files in this folder are copies of data and error files that the user has deleted. See the Files page for a description of thesefiles.

If you are going to replace the USB memory with an empty one, you must be sure the necessary files of the the USB module.The easiest way to do this is to copy all of the files from the current USB module onto the new one. Then delete the user datafiles from the new module. You should also delete the "Backup" folder, and the "ErrorFile.txt" file.

The connections to the Processor are shown below.

holding the cover in place.The USB module isplugged into a socket on thesmaller processor board onthe main circuit board. Pullthe USB memory out of itssocket while holding thesocket. If you don't supportthe socket, the board can bedamaged.

Replace the USB memoryby pushing it into thesocket until it snaps intoplace.

Important: Do not disturb any of the other files on the USB memory. These arerequired for the system to operate correctly. You can delete the datafiles after you copy them to your PC.

Important: Some USB memory drives are not compatible with the Level 1module. We recommend SanDisk modules. Do not use Kingston orHP modules.

RS485 Connector

The RS485 connector is dedicated to the RS485 adapter. It cannot be used for any other purpose.

Files on the Level 1 Module that have a .cdv extension are used by the QWIC software to configure the unit for specificapplications, including the user interface. These files are stored on the Level 1 Module in the folder (directory): \HardDisk\NVRAM\QWIC. These files contain an Access Code, which is similar to a password, and limits who can use those files.

Each .cdv file contains a code number that identifies who can use it, and a "mask" that allows many users to use the file. Whenthe .cdv file is read, the Processor compares the file's code number with the QView code number. The mask is then applied tothis comparison, and if there are "significant" differences, the file will not run.

The Access Code is useful to restrict who can run a particular program. For example, you may want all your employees to runthe "Elevator Inspect" program, but only certain people can run the "Elevator Setup" program. Each employee's computer orPDA can be assigned a specific access code that determines what programs they can run.

You can control which users are able run a particular Device by changing the Access Code and mask. The Access Code isrepresented by 4 decimal numbers, to make it more convenient to enter. Each entry can have a value of 0 - 255. (This is similarto the Internet Protocol (IP) address used in networks.)

The mask consists of 4 numbers as well, but it is their binary bit values that are important, not their numeric value. Each bit thathas a value of 1 means that the corresponding bit in the code number is important. If the bit value is 0, the corresponding bit inthe access code is ignored.

The comparison of the file's code number and the viewer's code number is actually performed bit-by-bit.

For example suppose the .cdv file has a code number of 123-245-1-111 and the QView program has a code number of 123-245-2-45. The mask value is 255-255-252-0. The comparison results are as follows:

In this case the QView viewer would be allowed to run the .cdv file, since there are no significant differences in the bits. (Thedifferent bits are ignored by the mask.) If the Viewer's code number was 123-245-4-45, it would be rejected.

Also note that in this case there are many access codes that will match, as long as the significant bit positions match. This allowsyou to construct Device files that match a group of users, such as employees of your company, while preventing others fromusing the .cdv file.

To change the Access Code of a file, use Telnet to connect to the Level 1 Module.

Once you are connected by Telnet, type "ResetAccessCode".

Enter the name of the .cdv file whose access code you want to change.

Enter the file's current Access Code.

Enter the new Access Code.

Enter the new mask.

The program will then change the Access Code in the file and save it.

Note: Make sure you remember the Access Codes of the .cdv files or you will not be able to change them.
