of 806-824 MHz and requires a 1/4-wavelength antenna. The IPSeries High Speed Mobile Radios are intelligent devices designed for the challenging requirements of mobile data and voice applications. Mounted in vehicles, other intelligent devices may connect to the serial or Ethernet ports for connectivity back to the Internet Protocol Network Controller (IPNC) and other such servers. It provides the mobile link to land-based wired networks. The high speed mobile radio circuit boards are built using surface mount technology (SMT) and through-hole components. Figure 1: IPSeries High Speed Mobile Radio (Front View) Product Functionality The high speed mobile radio utilizes a high-performance, 32-level QAM. Further it uses state-of-the-art OFDM technique. This new technique will enable the high speed mobile radio to transmit and receive more than 100 Kbps data in a 25 kHz band. The high speed mobile radio features low power consumption, high performance integrated GPS receiver. Embedding this technology in the mobile radio lowers the cost of acquiring GPS data from vehicles and ensures optimal performance. The high speed mobile radio technology includes Diversity Reception (DR) capability. DR reduces the effects of fades in a multi-path environment. With the use of two (2) antennas mounted at a calculated distance on the roof of the vehicle the Diversity Reception System (DRS) minimizes the effects of fading by intelligently selecting the receiver with a better signal. Diversity is most effective when the vehicle is in motion. 703800.DOC Page 3 SECTION 1: OVERVIEW External Features As seen in Figure 2 below, the IPSeries High Speed Mobile Radio technology is enclosed in a compact and sturdy aluminum case.

Page 14 SECTION 3: INSTALLATION INSTRUCTIONS Antenna Configuration Two (2) antennas are mounted and installed on the roof of the vehicle using specific measurements for distance. To mount and install the antennas, perform the following steps: Step 1 Install antennas (see the figure below). Observe correct separation between antennas (refer to Table 8: Mobile Antenna Distance Matrix). This table provides midpoint distance calculations and minimum and Near-Field Exclusion Zone (NFEZ) for proper diversity reception. The NFEZ distance is an absolute minimum. The greater the distance between the antennas to any other surfaces will result in improved performance. Step 2 Cut a mounting hole in the roof of the vehicle using an electric drill or hole saw. The antenna-mounting hole provides ground connection to the antenna. Ensure that a metal-to-metal connection between the antenna shields exists. Figure 12: Antenna Distance Configuration 703800.DOC Page 15 SECTION 3: INSTALLATION INSTRUCTIONS The previous figure represents the recommended front-to-rear antenna installation. The receiver antenna (RX2) should be the antenna nearest to the light bar. Step 3 All antenna mounts must be environmentally tight. Install or use O-rings to seal the antenna base to the rooftop of the vehicle. Step 4 Route the coaxial cables to the mobile radio through one of the hollow spaces in the roof supports into the trunk compartment where the high speed mobile radio is mounted. Both antennas should be checked and tested to ensure they are functioning properly. If these installation guidelines are followed, it will be safe for persons to stand at a distance no less than 39 inches from the antennas while the mobile radio is in transmit mode. Measuring Return Loss The following test is performed without any power, thus can be performed immediately after the installation of the coax and antenna, following the installation of the N-type connector on the coax. To measure Return Loss, perform the following steps: Step 1 Select the appropriate Antenna Analysts to perform the test. Step 2 Connect the antenna to be tested to the Antenna Analyst. Step 3 Turn on the Antenna Analyst and the Return Loss (RETL) is displayed in dB to the left of the Voltage Standing Wave Ratio (VSWR) curve. The Return Loss Specification is â14 dBm or greater (with good antennas the typical range will be between â14 and â28). Measuring Voltage Standing Wave Ratio To measure the Voltage Standing Wave Ratio (VSWR) Reflected Power, perform the following steps: Step 1 After selecting the appropriate Analyst and connecting the antenna to be tested, press F1 to access the Analyst Menu. Step 2 Press F1 again to access the Display (DSPLY) menu, which lists the modes. Step 3 Press F2 to select the VSWR display mode.

Step 2 Program the radio to the current Firmware revision using the AVR programming utility. Step 3 Connect a PC to the radio and launch the IPMessage program. In the IPMessage window, type factory default, press [ENTER], and the radio displays the radioâs default values. Step 4 Enter the appropriate values for the radio's frequency band. The following values were used for an 806 to 824 MHz mobile radio: 703800.DOC Page 29 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 44.545 MHz 2nd injection frequency at U6 pin 4, adjust trimmer capacitor CV22 for the maximum amplitude of this injection frequency. The maximum amplitude must be between -3 to -5 dBm. Record this value on the Test Data Sheet. Step 3 Repeat Step 2 by monitoring U9 pin 4 and adjusting CV20 for Receiver2 IFLO. Record this value on the Test Data Sheet. Receiver 1 Perform the following steps to adjust receiver 1: Step1 Inject an on-frequency carrier signal with amplitude of -80 dBm, modulated with a 1 kHz test tone at +/- 5.0 kHz deviation into receiver 1's antenna port. Step 2 While monitoring the voltage at RSSI1 Test Point with a DMM, adjust trimmer capacitor CV15 and C16 to midway between the points where the oscillation stops. Step 3 While monitoring the DC level of the recovered modulation; adjust potentiometer RV6 for a reading of 2.500 VDC +/- 1 mV DC. Step 4 While monitoring the amplitude of the recovered audio signal, adjust potentiometer RV5 and RV6 for a reading of 350 mV RMS and 2.500 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). Step 6 While monitoring the recovered audio signal at TP1, verify the distortion is less than 3% adjust CV15 and CV16 if necessary to achieve less than 3% distortion. Record this value on the Test Data Sheet. Step 7 While monitoring the recovered audio signal at TP1, verify the SINAD is -118 dBm or better. Record this value on the Test Data Sheet. Receiver 2 Perform the following steps to adjust receiver 2: Step 1 Inject an on-frequency carrier signal with amplitude of -80 dBm, modulated with a 1 kHz test tone at +/- 5.0 kHz deviation into Receiver 2's antenna port. Step 2 While monitoring the voltage at RSSI2 Test Point with a DMM, adjust trimmer capacitor CV6 and CV7 to midway between the points where the oscillation stops. 703800.DOC Page 30 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). Step 6 While monitoring the recovered audio signal at TP1, verify the distortion is less than 3%, adjust CV3 if necessary to achieve less than 3% distortion. Record this value on the Test Data Sheet. Step 7 While monitoring the recovered audio signal at TP1, verify the SINAD is -118 dBm or better. Record this value on the Test Data Sheet. Transmit Data Perform the following steps to adjust transmit data: Step 1 Use IPMessage to set the transmit power to 0. Step 2 Using the x=1400,n command of IPMessage to generate transmit data messages while observing the transmitted signal on the HP RF communications test set, adjust pot R33 for minimum frequency error while transmitting data messages. Step 3 Turn potentiometer RV1 fully counterclockwise. Step 4 Adjust RV2 for deviation of 4.9 kHz. Step 5 Using calibrated base station, and monitoring the uplink received data quality on the base station's Hyperterminal screen, slowly turn RV1 clockwise until consistent data quality readings of 240 - 248 are achieved using 1400 character test messages. Data quality reading should not be less than 240 for 1400 character messages. Step 6 If unable to reach the data quality readings then ask for Technical Support. Poor data quality readings are indicative of poor group delay performance, or other defect. Verify transmit deviation, frequency error, and transmitting data messages quality and record this data on the Test Data Sheet. Power Setting Perform the following steps to adjust the transmit power control: Step 1 Attach a power attenuator to the transmit port of the radio. Step 2 Using the x=1400,n command of IPMessage, and while monitoring the transmit power level on the HP communications test set, check the level of the transmit power. Using IPMessage set the power setting to txpower=0. The radio should have an output power level of approximately 1 mW. Record this value on the Test Data Sheet. 703800.DOC Page 31 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. Do not to exceed 30 Watts of output power, as this may reduce the life of the amplifier. Receive Data Perform the following steps to verify the receive data performance: Step 1 Using the DOS ping command on the PC connected to the radio, ping the network controller to generate uplink and downlink data messages. The following command will generate one Hundred 500 character messages: >;Ping 192.168.3.3 -n 100 -l 500 Step 2 Observe the data quality readings on the IPMessage window of the PC connected to the radio using the V (for Verbose) command in the IPMessage program. With the mobile radio's antenna connected to receiver 1, verify the received data quality readings are consistently 248s. Data quality readings should also be verified at the base station using the V command on the Hyperterminal window. Step 3 Verify receiver 2 data quality readings are also consistently 240 to 248s by changing the antenna from receiver 1 port to receiver 2 port. In this manner both uplink and downlink data quality can be verified. Record this data on the Test Data Sheet. Final Test A final test must be performed prior to shipping the M64800D25 mobile radio to the customer. This final test will verify that the timing characteristics are correct and that both transmit and receive data quality readings are consistently high. Perform the following steps for the final test: Step 1 Attach the 40dB 100-Watt power attenuator to the transmit port of the radio. Step 2 Program the radio for full power operation. The tx power level setting can be found in the radio's Test Data Sheet. Step 3 The setting must not to exceed 40 Watts. Attach a digital scope to the base station as described in section the next section, Uplink Hardware Timing Verification. Using the x=1400,19 command (which will cause the radio to transmit 19, 1400 character messages), verify the following: Transmit frequency of radio is adjusted for minimum frequency error of +/- 100 Hz. 703800.DOC Page 32 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. This indicates that some of these test messages will be slightly high in frequency, some messages will be slightly low in frequency, and some messages will be right on frequency. Step 4 Verify the transmit deviation is 4.9 kHz Step 5 Verify the timing characteristics are identical to the plots in the next section, Uplink Hardware Timing Verification. Step 6 At the base station monitor PC, verify that all the data quality readings are 240 and higher. Step 7 Move the scope probes to monitor the timing at the mobile radio as described in Downlink Hardware Timing Verification. Generate test messages by issuing a ping command to the IPNC from the PC attached to the radio. The following command will cause 100 pings, 500 bytes in length to be transmitted from the mobile radio and echoed by the IPNC through the base station: .>;Ping 192.168.3.3 -n 100 -l 500 -w 2000 Step 8 Set CRC =1 Enable on the radio Step 9 Verify the timing characteristics are identical to those in Downlink Hardware Timing Verification. Step 10 Verify that both receivers on the mobile radio report data quality readings of 240 or higher (248 is typical). This can be accomplished by installing the antenna on the TX/RX1 port and verifying RX1 is selected by observing the RX1 LED on the mobile radio and installing the antenna on the RX2 port and verifying RX2 is selected by observing the RX2 LED on the mobile radio. Step 11 Reset CRC = 0 Disable on the radio Step 12 In IPMessage, type the ? command to radio. Copy the radio settings and paste them into the Test Data File. Step 13 Perform a close visual inspection of the radio closely inspecting manufacturing related problems (loose screws, solder particles, etc.). 703800.DOC Page 33 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. As seen in the above plot, the mobile radio's transmit carrier has ramped up to full power (channel 1) in just a few milliseconds. The recovered modulation (channel 2) is stable by this time. There follows a few milliseconds of quiet time followed by 12 milliseconds of symbol sync time. 703800.DOC The recovered modulation from a mobile radio should look identical to this plot. The recovered modulation signal should be approximately 1.0 Volts peak-to-peak and should be centered at approximately 2.5 VDC as is indicated in the figure above. Page 34 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. This enables the base station's modem CS (Chip Select) line to be viewed. The base station's microcontroller, upon detecting a step response in the RSSI (caused by the mobile radio's transmitter coming up to power), waits a period of time equal to the programmed value of the base station's carrier detect delay time. The microcontroller then instructs the modem to search for the modem synchronization preamble. When the base station instructs the modem to look for sync tones, the modem's CS line transitions low. This can be seen in the above plot. Approximately 10 milliseconds after the mobile radio's transmitter causes a step increase in the base station's RSSI, the CS signal goes low momentarily. As can be seen, the sync tones are stable by this time and the modem quickly establishes synchronization. 703800.DOC Page 35 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. 703800.DOC There is a very short period of quiet time (no modulation) followed by approximately 12 milliseconds of modem synchronization time (sync time). Page 36 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. When the microcontroller instructs the modem to look for frame sync, it asserts the modem's CS line (active low). In this plot, the modem's CS line can be seen to transition low approximately 3 milliseconds after the base station's transmitter has come up to full power. The recovered modulation should be centered at approximately 2.5 VDC and should have an amplitude of approximately 800 mV peal-to-peak as indicated in the plot above. 703800.DOC Page 37 SECTION 5: FCC LABEL M64800D25 Data Transceiver FCC Label Placement M64800D25 Data Transceiver FCC Label 703800.DOC Page 38 APPENDIX A: CIRCUIT BOARD DIAGRAMS High Speed Mobile Radio OMAP 5910 Circuit Board High Speed Mobile Radio RF Circuit Board 703800.DOC Page 39 APPENDIX B: M64800D25 TEST DATA SHEET Program and Configure Mobile Radio Date Serial Number Firmware Revision Tester Adjustment / Alignment Procedures Receiver Injection Parameter Spec Injection Frequency Error at RXINJ1(within +/- 100 Hz of exact injection frequency) U17 pin 4 power level Measured +/- 100 Hz -3 to -5 dBm Receiver 1& 2 Parameter Spec Audio DC Amplitude (1 kHz Test tone @ 5.0 kHz Deviation) 2.5 VDC +/- 1mV Audio AC Amplitude (1 kHz Test tone @ 5.0 kHz Deviation) 350 mVRMS +/- 1mV Distortion (1 kHz Test tone @ 5.0 kHz Deviation) 3%< SINAD 12 dB (1 kHz Test tone @ 5.0 kHz Deviation) -118dBm > 703800.DOC Receiver 1 Measured Receiver 2 Measured Page 40 APPENDIX B: M64800D25 TEST DATA SHEET Transmit Section Parameter Spec Transmit Modulation Deviation (4.9 kHz while transmitting 1400 character test message) 4.9 kHz Transmit Data Quality (While transmitting 1400 character test messages to the base station) 240 > Transmit Frequency Error (Transmitting 1400 character test message) Measured +/- 100Hz Transmit Power Control Caution: Do not to exceed 20-Watts RF output power during this test.
