Alarm Code Definitions - GE TransNET 900 Reference Manual

With the exception of alarm code 00 (network address not programmed),
major alarms generally indicate the need for factory repair. Contact the
factory for further assistance.
Minor alarms report conditions which, under most circumstances, will not
prevent transceiver operation. This includes out-of-tolerance conditions,
baud rate mismatches, etc. The cause of these alarms should be investigated
and corrected to prevent system failure.

Alarm Code Definitions

Table 18 contains a listing of all event codes that may be reported by the
transceiver. Additional alarm codes may be used in future firmware releases
or are used by the factory.

Description
The network address is not programmed.
Improper firmware detected for this radio model.
One or more of the programmable synthesizer loops is reporting
an out-of-lock condition.
The system is reporting that it has not been calibrated. Factory
calibration is required for proper radio operation.
The DSP was unable to properly program the system to the ap-
propriate defaults. A hardware problem may exist.
Receiver time-out alarm.
The unit address is not programmed.
A data parity fault has been detected on the DATA connector.
This usually indicates a parity setting mismatch between the ra-
dio and the RTU.
A data framing error has been detected on the DATA connector.
This may indicate a baud rate mismatch between the radio and
the RTU.
RF output power fault detected. (Power differs by more than 2
dB from set level.) Often caused by high antenna system SWR.
Check antenna, feedline and connectors.
The system is reporting an RSSI reading below –105 dBm.
The transceiver's internal temperature is approaching an
out-of-tolerance condition. If the temperature drifts outside of
the recommended operating range and the transceiver may fail.
