Appendix A: Error Messages
Solution
Connect a detectable antenna (antenna must have some DC resistance).
FAULT_TEMPERATURE_EXCEED_LIMITS – 504h
Cause
The module has exceeded the maximum or minimum operating temperature and will not
allow an RF operation until it is back in range.
Solution
Take steps to resolve thermal issues with module:
Reduce duty cycle
Add heat sink
Power Save Mode (non-DRM Compliant)
FAULT_POOR_RETURN_LOSS – 505h
Cause
The module has detected a poor return loss and has ended RF operation to avoid module
damage.
Solution
Take steps to resolve high return loss on receiver:
Make sure antenna VSWR is within module specifications
Make sure antennas are correctly attached before transmitting
Check environment to ensure no occurrences of high signal reflection back at
antennas.
FAULT_AHAL_INVALID_ANTENA_CONFIG – 507h
Cause
An attempt to set an antenna configuration that is not valid.
