TROUBLESHOOTING
1. Did you check to make sure that Remote, Coms, Basic, or any other part of the
system isn’t trying to use the com port you wish to use for GPRS? Issuing
“status” at the command prompt will list all ports that Remote has been
configured to support.
2. Did you check to make sure the LAN device is turned off?
3. If you just configured a serial port for the first time, have you tried rebooting the
unit?
4. Observe the GPRS Diagnostics Tab while a connection is attempted and verify
that connections are being scheduled, and watch for an issue during the
connection negotiation.
5. Verify that the GPRS device is being powered up correctly by pressing ON in the
GPRS Diagnostics Tab.
6. Issuing “report high” or even “report debug” at the command prompt is a good
way to get real time diagnostic information about the performance of the GPRS
SLL and the system in general. You can monitor SSP messaging by issuing
“report ssp”. SSP over TCP/IP messages may be viewed by issuing “report ssp0”,
or the options may even be combined by issuing “report ssp ssp0”.
7. The system status page will show information about the most recent diagnostic
messages and the current state of the GPRS device. This can also be displayed on
demand at the command prompt with the “info” command.
8. The system.log can be examined to look for status messages, connection errors,
and transmission errors.
9. Use the GPRS Diagnostic page to send test mail messages.
10. If you need to reach your station for maintenance, but it’s configured to turn on
only when transmitting, you may try sending the SMS command “POWER ON”
to the station. The SMS command won’t be able to go through while the modem
is powered off, but it may get through on a retry or if you happen to time it for
when the station is transmitting.
