Product Description
The M64450G25 Mobile Radio works within a frequency range of 450-506 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 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.
Figure 1: IPSeries High Speed Mobile Radio (Front View)
Product Functionality
The IPSeries High Speed Mobile Radio utilizes a high-performance, 4-level Frequency-Shift Keying (FSK)
wireless data modem for 32 kbps operation, 16-level FSK for 64 kbps in 25 kHz channels; a multi-layered
approach to signal reliability. It 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 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) antennae 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.

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.NNN –n 25 –l 500 –w 4000
After entering the command, press [ENTER] to continue.
When entering a command, pay special attention to the spaces and the
characters being typed.
# If the calibrated base station does not respond, check the syntax of the Ping command and verify
the IP address is correct.
If the ping command runs but high packet loss figures are shown, perform the following:
1. Verify that the calibrated base station and mobile radio antennae are separated by at least
10 feet. If the antennae are too close, the mobile radio receivers can be overloaded by the
transmitters resulting in intermittent communication and high data errors.
2. Verify the calibrated base station parameters are correct for the mobile radio. Such
parameters include IP addresses and complementary RX/TX frequencies.
3. Check to ensure the data and power cables are connected correctly.
4. If the Ping command continues to fail, test using a mobile radio that is known to be working
properly.
Step 10 Check the test laptop and verify that the Packets Lost Percentage is zero to 1%
packet loss. Greater losses may indicate a problem with the transmitter/receiver
1, or modem circuitry.
Step 11 Change the antenna on the mobile radio to the RX2 antenna input.
Step 12 Connect the RF attenuator to the mobile radio’s TX/RX1 antenna input.
Step 13 Connect the second antenna to the RF attenuator. In the IPMessage window,
enter receiver=2. This will allow the mobile radio to only receive via Receiver 2.
Step 14 Type the following command at the MS-DOS prompt replacing
NNN.NNN.NNN.NNN with the IPNC IP address:
Ping NNN.NNN.NNN.NNN –n 25 –l 500 –w 4000
After entering the command, press [ENTER] to continue.
Step 15 Check the test laptop and verify that the Packets Lost Percentage is zero to 1%
packet loss. Greater losses may indicate a problem with the receiver 2, or
modem circuitry.

SECTION 4: FACTORY TEST PROCEDURE
M64450G25-FCCRpt.doc Page 36
Transmitter Power
Step 1 Set the Service Monitor to measure the transmitter frequency of the base station.
Step 2 Set the Service Monitor filters to “<20 Hz HPF” and “15 kHz HPF”.
Ensure the Service Monitor can handle the full power transmission of the

Step 3 Connect a coaxial cable from the output of the base station (or connected
attenuator) to the Service Monitor’s RF In port.
Step 4 In IPMessage, type the command “X = 1400,20”. The base station will transmit
20 packets of 1400 bytes each. This continuous transmission will last
approximately 10 seconds.
Step 5 On the Service Monitor note the transmitter power at the beginning of the
transmission and observe whether the transmitter power drops over the course of
the transmission.
Step 6 Transmitter Power Output must begin at a level between 20 and 35 watts and
must not drop by more then 5 watts over the course of the “X = 1400,20”
command.

MSR does not meet 94% proceed with Hardware Time Verification for trouble
shooting.
SECTION 4: FACTORY TEST PROCEDURE
M64450G25-FCCRpt.doc Page 37
Step 11 After completion of Data Quality and MSR tuning, record Firmware Settings. File
the Tune and Align Data Sheet with the Firmware setting in the IPMN Network.
Hardware Timing Troubleshooting
For trouble shooting data quality and MSR failures hardware timing can be verified as follows. The figure
below is an oscilloscope plot of a down-link data message from the base station to the mobile. Channel 1
is connected to the mobile's RSSI test point, Channel 2 is connected to the mobile's recovered
modulation (TP1), and Channel 3 is connected to the mobile’s modem chip select line. The scope’s
acquisition mode is high-resolution.
As can be seen from this plot, the base station'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.
The recovered modulation from a base station should look similar 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.
Below is another oscilloscope plot of an up-link data message from the mobile radio to the base station.
As in the last plot, Channel 1 is connected to the mobile's RSSI test point, Channel 2 is connected to the
mobile's recovered modulation test point (TP1), and Channel 3 is connected to the mobile's modem chip
select line. The scope's acquisition mode is now in the peak detect mode. This enables the mobile’s
modem CS (Chip Select) line to be viewed.
SECTION 4: FACTORY TEST PROCEDURE
M64450G25-FCCRpt.doc Page 38
The mobile radio’s microcontroller, upon detecting a step response in the RSSI (caused by the base
station's transmitter coming up to power), waits a period of time equal to the programmed value of the
mobile'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 base station's transmitter causes a step increase in the mobile'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.
The figure below is a plot of the down-link 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. Note there is a very short period of quiet time (no
modulation) followed by approximately 12 milliseconds of modem synchronization time (sync time).
SECTION 4: FACTORY TEST PROCEDURE
M64450G25-FCCRpt.doc Page 39
The next plot 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 mobile 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 the amplitude
of approximately 800 mV peal-to-peak as indicated in the plot above.
SECTION 4: FACTORY TEST PROCEDURE
M64450G25-FCCRpt.doc Page 40

‘serial number’ and ‘radio mac address’.
Step 3 Modify firmware settings as needed and run IPLinkView on the mobile radio on
the highest and lowest frequencies programmed in the mobile radio.
Step 4 Run IPLinkView until a GPS connection is established.
Step 5 Run ‘firmware check’ for the specific Customer.
SECTION 4: FACTORY TEST PROCEDURE
M64450G25-FCCRpt.doc Page 41
Final Inspection
The final inspection of the mobile radio is a critical step that translates directly into confidence in the
product. Several areas must be checked on every base station before it can be shipped:
Screws- every screw hole must have the proper screw tightened the proper amount. The screws must
be new and cannot have rounded shoulders. Screw heads must be flush to the case.
Connectors- all screws must be tight and the internal portions of each connector must not be
damaged.
Covers and panels must not be dented or unduly scratched.
