odem configuration on RFD900 tools.
First ensure the firmware on the vehicle modem is the same as the one on the TX Pole, the version of
which can be obtained in the first page of the browser interface of figure 2
. If both versions don’t
match download the one currently in use on the TX Pole through the links in
Then on the
RFD900 tools click on ‘Upload Firmware’ and choose the *.bin file you just downloaded.
Wait until the process finishes (a message will appear at the bottom of the page) and reboot the
modem. You have successfully updated the firmware.
Then use the interface to configure the parameters described in
AIR_SPEED, NETID, TXPOWER, MIN_FREQ, MAX_FREQ and NUM_CHANNELS parameters should be
the same as the ones in the TX Pole modem. When connected directly through the FTDI cable the
vehicle modem will appear as local. If these parameters have been not modified on the TX Pole side
or they have been reset to default values by pressing the button 5 times rapidly, the easiest way to
configure them on the remote modem is by pressing ‘Reset to Defaults’ button.
Another important step is to set modem GPIO1.1 as a PPM output. This allows the modem pin 15 to
output the PPM stream received from the TX Pole modem. This will be configured automatically by
the First Run Wizard. In case the wizard were not to be used, enable this by checking the
‘CPI1_1R/COUT’ box in any and ensure
later on that
‘CPI1_1R/CIN’ is unchecked on the
TX Pole. Then
save the settings to upload the configuration onto the modem.
After the modem has been configured correctly it will be able to link with the TX Pole modem,
indicated by a solid green LED on both devices. From this point onwards the FTDI cable is no longer
needed to configure the vehicle modem. Instead this can be done over the air via the TX Pole using
the browser interface. This only works while the modem in the vehicle and TX Pole are linked as
indicated by a solid green LED.
