When complete click “OK” as shown in Fig. 8 The Guardian has now been configured and is ready for installation. INSTALLATION As noted on page 1 and page 2 , the Guardian footprint is different than the T - 96SR. Fig. 9 Figure 9 shows the mechanical dimensions for the Guardian. When mounting the radio, orientation should allow unrestricted airflow from the heat sink fins. If radio location, heat dissipation or duty cycle are a concern, the addi tion of the Guardian Fan Kit should b e considered. The following part numbers are available: - 150 - 5008 - 001 Factory Installed Fan Kit - 150 - 5008 - 002 Fi e l d Installed Fan Kit

5. Guardian and T - 96SR Interoperability PN: 009 - 5006 - 001 Page 5 of 9 SET GUARDIAN PARAMET ERS Once the parameters for the existing T - 96SR system are logged, connect the Guardian to proper power supply voltage (10 - 30 VDC 60 Watt maximum at 10 watt RF power). Connect the antenna port to 50 ohm termination. Connect DB - 9 to DB - 9 data cable (PN# 697 - 400 8 - 408 or equivalent) to Guardian “Setup” port. - Note: Guardian FPS is defaulted to COM 1. Change if necessary. - Programming parameters are 57,600 8, N, 1, DTR – None - Handshaking should be set to “Buffered with no HS” With the Guardian connected to proper po wer source, antenna terminated and programming cable connected to the “Setup” port of the radio/modem , press the “Config” button in the upper left corner as shown in Fig. 4 . Fig. 4 The Guardian FPS will read and display the current configuration of the radio/modem connected to the computer. The configuration screen will display the Long and Short ID numbers of the modem. The Long ID number will typically be a 6 digit number. This number can be changed to suit the application’s needs (Fig. 5). Fig. 5 - The “PTT Watchdog” performs the same function as in the T - 96SR. This can be adjusted or left at factory default. - Information and real - time diagnostics are available on this screen. Used to prevent radio from transmitting over the top of another radio/signal Mode setting allows for Modem or Loader (analog) operation Click L ink Configuration for additional settings ID can be adjusted as required Morse Code identifier

7. Guardian and T - 96SR Interoperability PN: 009 - 5006 - 001 Page 7 of 9 - The Guardian uses a slightly different yet compatible modulation scheme as the T - 96SR o T - 96SR uses DRCMSK modulation o Guardian uses 2 Level FSK Refer to the parameters collected from the T - 96SR programming to set the “Modem Settings”. Pay close attention to the “Online Diags” settings. If Online Diagnostics are selected in the T - 96SR system , they MUST be enabled in the Guardian. Whether or not the Online Diagnostics are output to the Setup Port is left to the discretion of the customer. By selecting “Output Online Diagnostic Data to Setup Port” , the end user can view Online Diagnostics the same as a T - Base Diagnostic Port would show them. (Fig. 6) The remainder of the Modem Settings should match the T - 96SR sys tem. Dynamic Carrier Detect acts the same as the T - 96SR. The Carrier Sense level is set by selecting the “On” level. This is the RSSI (Receive Signal Strength Indication) or signal strength required to open the squelch setting in the receiver. The Carrie r Sense “Off” level is set automatically to 5 dBm below the “On” level. (Fig. 6) The comm port s ettings must match the RTU/PLC equipment used in the system. Typically these settings will be the same as the RF Link Settings but can be set differently. When used in an existing T - 96SR system , these will be the same as the RF Link Settings. - Select the correct Baud rate, Parity bit and Stop bit values. - Transmit control mode can be either RTS/CTS handshaking mode or DOX (Data Operated Transmit) mode. - The Guardia n also offers the choice of RS422 and RS485 serial connections. When all parameters are selected and verified, press the “Save Changes” button at the bottom of the Link Configuration screen. The Link Configuration screen will close. There are two options for programming the Guardian : Press the “Write Guardian” button or press F10 on the programming keyboard. See Fig. 7. Fig. 7 Option 2: Press F10 to program radio Option 1: Press the Write Guardian button to program radio

9. Guardian and T - 96SR Interoperability PN: 009 - 5006 - 001 Page 9 of 9 Contact you sales representative for further information. The a ntenna connection of the Guardian is a TNC - Fem ale 50 ohm con nector. See page 2 for available cables from CalAmp Corp. Serial connection is a DB - 9 Female. This is a DCE connection. The RTU/PLC control equipment may be DTE or DCE equipment. If the RS232 serial connection is DTE , a ‘s traight through’ serial cable shou ld be used. If the equipment has a DCE connection , a ‘null modem’ serial cable will be required . For RTS/CTS handshaking flow control , 5 wires will be required for operation. These are as follows: (see Table 1) Table 1 - Pin 2 Receive Data – Data received by radio and output to a RTU/PLC - Pin 3 Transmit Data – Data sent to modem to be transmitted by the radio - Pin 5 Signal Ground – RS232 ground and also radio/modem chassis ground potential - Pin 7 Request to Send – RTS raised to RS232 ‘High’ to start transmit m ode and prepare mode to receive data - Pin 8 Clear to Send – CTS return RS232 ‘High’ to RTU/PLC 30 mSec after RTS is raised. Modem is ready to receive data DOX mode operation does not require RTS/CTS handshake control. When data is received on Pin 3 (TXD) , d ata is buffered and the radio is set to transmit mode. Data is transmitted when the radio/modem is ready to send it. DOX mode requires 3 wire connections for operation. These are as follows: (see Table 1) - Pin 2 Receive Data – Data received by the radio an d output to a RTU/PLC - Pin 3 Transmit Data – Data sent to modem to be transmitted by the radio - Pin 5 Signal Ground – RS232 ground and also radio/modem chassis ground potential Summary: Further information is available in the Guardian Technical Manual part n umber 001 - 5006 - 000.

Guardian and T - 96SR Interoperability PN: 009 - 5006 - 001 Page 3 of 9  The 697 - 0000 - 001 cabl e could be removed and the PLC/RTU can be connected directly to the radio.  If cable length is an issue , a short DB - 9 to DB - 9 cable can be added between the PLC/RTU and the Guardian radio. - Mechanical footprint o The T - 96SR and the Guardian do not use the same mechanical footprint. o Reference Guardian Technical Manual 001 - 5006 - 000 which shows the mechanical layout of the radio o See page 13 Section 1.4.7 fig. 1 - 2 for chassis dimensions - Programming o The Guardian uses programming software unique to the Guardian o The G uardian programming cable is simply a standard DB - 9 to DB - 9 serial cable and no longer requires unique cabling. o Programming cable PN# 697 - 4008 - 408 PROGRAMMING AND SETU P Programming of the T - 96SR and Guardian is done using unique FPS for each wireless modem. Since both wireless modems are transparent in their operation with the RTU/PLC there is no need to be concerned about Master and Remote configurations. The first step in adding a Guardian into an existing system is to read the parameters of the T - 96 SR. Log parameter settings so that a thorough record is available for programming the Guardian. See Figures 1 - 3. Fig. 1 Note which parameters are selected Note how all data settings are selected. Guardian is compatible with “Enhanced Only” data type

6. Guardian and T - 96SR Interoperability PN: 009 - 5006 - 001 Page 6 of 9 - CWID is a new feature not available on the T - 96SR. Station /License call si gns can be transmitted at selected intervals. This feature is used when the SCADA system shares a ‘Voice Channel’ with another system and is required to identify itself using Morse code. (Fig. 5) - CSMA (Carrier Sense Multiple Access) is a feature added to t he Guardian that is not available on the T - 96SR. o This feature allows the radio to monitor the RF channel for activity o There are two modes to select from:  No TX when the radio/modem is receiving valid data  No TX when the radio/modem is receiving an RF carri er  See Fig. 5 - There is a new feature added to the Guardian that allows the radio to be used a s a modem (T - 96SR compatible) or be used as an analog radio (DL3400 compatible). For this application , only the ‘Modem’ mode will be used. (Fig. 5) LINK CONFIGURATION Press the “Link Configuration” button shown in Fig. 5 to advance to the modem settings. This is the screen that sets the RF channel frequencies and modem settings. See Fig. 6. Fig. 6 Unlike the T - 96SR where all 8 channels were programmed one channel at a time, the Guardian has a “Default” setting that will set all 8 channels simultaneously. (Fig. 6) - Using the information collected from the T - 96SR programming , set the RF Link information to match the system parameters. - Channel bandwidth is now selectable for either 25 KHz or 12.5 KHz - Set Power Output to the desired power level; 1 - 10Watts - The Guardian allows for the OTA data settings to be different from the user comm port settings. Care must be taken to ensure the OTA settings are the same as the T - 96SR system settings. (Fig. 6) o Channel Bandwidth must match the existing system o Data rate (Baud Rate) must be the same as the T - 96SR o Data bits, Parity and Stop Bits must be the same All 8 RF channels can be set by using the Default Settings RF Link Settings - Ensure parameters match the existing T - 96SR settings Selection of Online Diagnostics is critical to proper system c ompatibility Set CD “On” Level to desired signal strength. Select proper com port settings to match PLC/RTU
