9.6 Satellite troubleshooting
To identify some possible causes of the common failures in satellite telemetry (IRIDIUM
or BGAN), check the following steps:
1. Power on the logger (reset it in case it is already powered on) and check if the
display turns on and its red LED (modem) is blinking;
2. Check the communication status in the display´s upper right corner. As soon as
the logger detects the Iridium modem, ‘SAT’ should be shown. As for the BGAN
modem, ‘BGAN’ should be shown. A while later, if the logger acquires signal, it
will show on upper right corner the coverage bars according to the signal
strength;
3. If SAT or BGAN is not shown on upper right corner, check the power and data
cable connection from logger to modem, as well as verify that the modem has
been correctly configured;
4. If no coverage bars are shown, then check antenna orientation, antenna cable
proper connections with special attention to the status of antenna cable
connectors. Also, make sure that the satellite´s plan package is active (at least
for 24h);
Remarks:
The BGAN antenna has to be precisely and manually oriented, as described in
the manufacturer´s manual.
The Iridium antenna has to be installed in vertical position with cable entry
facing to the floor. The antenna should have the largest open sky visibility with
the only interference of the tower structure itself.
If all steps above were executed and the communication problem persists,
please do not hesitate to contact our local technical support.
