5. Troubleshooting Tools and Tips
Problem: I have intermittent successful connections between
the remote and base station modem. The signal strength is
weak and the data transfer speeds are slow.
Solution: The antenna may not have a complete 180° view of
the sky. Some objects and debris such as snow and trees can
interfere with communications. Make sure that there are no
obstructions to the antennas when installing. You may need to
reposition or elevate your antenna to obtain the best reception.
The Signal Quality AT command can be used to confirm signal
strength during the installation/repositioning of the antenna. This
will require the use of a laptop connected to the C2462 interface
and a terminal emulator. Once the terminal emulator is
connected the following command can be entered to check
signal strength:
AT+CSQ
The modem should return a value of between 0 and 5 within 10
seconds. Attempt to get the largest value during your
installation/repositioning.
Problem: LoggerNet immediately brings back an error message
saying that communications with the station have failed.
Solution: Sometimes PakBus© beacons sent to other stations
by LoggerNet interfere with successful communications using
Iridium Satellite Modems. Either turn PakBus© beaconing off or
disable communications with your other stations when you
attempt to download using Iridium. This can be accomplished in
the Setup applet in LoggerNet. Finally, reboot LoggerNet to clear
the communications queue of any tasks.
