SECTION 3: INSTALLATION INSTRUCTIONS Preliminary Testing and Troubleshooting This section provides a functional preliminary test for the mobile radio once installed. It is used to determine the condition of new mobile radios before being placed into service. Checklist of Required Material Table 9 provides a checklist of the tools and equipment required to perform the preliminary test procedure. TABLE 9: CHECKLIST OF REQUIRED MATERIAL TO PERFORM PRELIMINARY TESTING NO.
SECTION 3: INSTALLATION INSTRUCTIONS Base Station Setup for Testing The system must be programmed with the customer’s parameters before any tests are made on the mobile radio. To prepare the base station to be used in the mobile radio test, perform the following steps: Step 1 On the laptop at the Windows desktop, click on the Start button and select Accessories, Communications, and HyperTerminal. Step 2 Power up the base station.
SECTION 3: INSTALLATION INSTRUCTIONS Preliminary Test Procedure and Troubleshooting Prior to performing this procedure, the IPNC IP address must be known. Note taking during preliminary testing is crucial to ensure necessary information is gathered to use for additional testing or if the mobile radio needs to be submitted for repair. To test mobile radio functionality, perform the following steps: Step 1 Perform a visual inspection of the mobile radio and its connections.
SECTION 3: INSTALLATION INSTRUCTIONS # If a message window appears indicating the connection was unsuccessful, perform the following troubleshooting steps: 1. Ensure the serial and power cables are properly connected. 2. Verify that the mobile radio lock LED (light emitting diode) is on, indicating the mobile radio has power. 3. Ensure that the SLIP2IPMN dial-up connection is running. 4. If problem persists after retrying, replace the serial cable with one that is known to be working properly.
SECTION 3: INSTALLATION INSTRUCTIONS Step 8 At the desktop, click on the Start button and select Programs and MS-DOS Prompt. The MS-DOS window displays. Step 9 Ping the IPNC commanding the transmitter to send 25 messages of 500 characters each to the IPNC as well as a response through Receiver 1 back to the laptop or desktop PC by typing in the following command at the MS-DOS prompt replacing NNN.NNN.NNN.NNN with the IPNC IP address: Ping NNN.NNN.NNN.
SECTION 3: INSTALLATION INSTRUCTIONS Confirming High Speed Mobile Radio Receiver Sensitivity This set of instructions provides the user with a list of required equipment and steps needed to confirm mobile radio Receiver sensitivity. Requirements IPSeries High Speed Mobile Radio DC power supply, 13.
SECTION 4: FACTORY TEST PROCEDURE Equipment List The following table lists the equipment required to perform the M64780D25 Mobile Radio Factory Test Procedure: TABLE 10: EQUIPMENT REQUIRED TO PEREFORM FACTORY TEST PROCEDURE QTY DESCRIPTION MANUFACTURER MODEL 2 PC’s One for Mobile One for Base 1 Service Monitor – Communication Test Set 1 Digital multi-meter 1 DC power supply w/ ammeter, 13.
SECTION 4: FACTORY TEST PROCEDURE Programming and Configuring Mobile Radio Once the appropriate equipment for performing the factory test are gathered, perform the following steps to program and configure an M64780D25 Mobile Radio: Step 1 Enter the mobile radio serial number, date test being performed, and tester’s name on the Test Data Sheet (see Appendix B). Step 2 Program the radio to the current Firmware revision using the AVR programming utility.
SECTION 4: FACTORY TEST PROCEDURE Adjustment / Alignment Procedures Receiver Injection Perform the following steps to adjust the receiver injection and injection frequency: Step 1 While monitoring the receiver injection frequency at RXINJ1, input the value for the DAC frequency control for minimum frequency error (+/- 100Hz). Record this value on the Test Data Sheet. Step 2 While monitoring the 44.
SECTION 4: FACTORY TEST PROCEDURE Step 3 While monitoring the DC level of the recovered modulation, adjust potentiometer RV4 for a reading of 350 mV (+/-10 mV) RMS. Step 4 While monitoring the amplitude of the recovered audio signal, adjust potentiometer RV3 for a reading of 2.500 (+/-10 mV) VDC. Step 5 Steps 3 and 4 are interactive adjustments, therefore repeat steps 3 and 4 until further adjustment is no longer required (i.e. when 350 mV RMS and 2.500 VDC are realized).
SECTION 4: FACTORY TEST PROCEDURE Step 3 Using IPMessage send the txpower= command to increase the power level settings until 30 Watts of output power is obtained. Record this value on the Test Data Sheet. Note that values on the table are to plot the codes vs. power output. The 30-Watt setting can be a code not on the table. Adjust txpower until the code is found that does not exceed 30.0 Watts. Record this value on the Test Data Sheet.
SECTION 4: FACTORY TEST PROCEDURE The x=1400,19 command will generate different messages with differing DC components. Each message will slightly slew the frequency off from the center frequency). Be careful to closely monitor the variation in transmit frequency due to these different messages and ensure that on average the transit frequency error has been minimized to within +/-100 Hz.
SECTION 4: FACTORY TEST PROCEDURE Uplink Hardware Timing Verification The figure below displays an oscilloscope plot of an uplink data message from the mobile to the base station. Channel 1 is connected to the base station's RSSI (XXX-12), channel 2 is connected to the base station's recovered modulation, and channel 3 is connected to the base station's modem chip select line. The scopes acquisition mode is high-resolution.
SECTION 4: FACTORY TEST PROCEDURE The figure below displays another oscilloscope plot of an up-link data message from the mobile to the base station. As in the last plot, channel 1 is connected to the base station's RSSI (J5-12), channel 2 is connected to the base station's recovered modulation test point, and channel 3 is connected to the base station's modem chip select line (U16-13). The scope's acquisition mode is now in the peak detect mode.
SECTION 4: FACTORY TEST PROCEDURE Downlink Hardware Timing Verification The figure below displays a plot of the downlink timing characteristics. Channel 1 is connected to RSSI, channel 2 is connected to recovered audio, and channel 3 is connected to the modem CS pin. The scope is in the high-resolution acquisition mode. There is a very short period of quiet time (no modulation) followed by approximately 12 milliseconds of modem synchronization time (sync time). 516.80548.
SECTION 4: FACTORY TEST PROCEDURE The plot shown in the figure below is the same as before but now the scope is in the peak detect acquisition mode. After the mobile radio detects a step response in the RSSI (caused by a down-link transmission), the radio's microcontroller waits an amount of time equal to the programmed value of the "carrier detect delay time" then instructs the modem to look for frame sync.
