Code values for individual minor alarm conditions are
given below:
Monitoring Alarms
on the Standby
Radio
There is a limited ability to monitor alarms on the standby radio without
using InSite software. You accomplish this using the command line
interface.
The ALARM, STAT, and SER commands take an optional parameter [A | B]:
• If you enter the command without the parameter, the response
applies to the active radio.
• If you enter the command with the [A] parameter, the response
always applies the the A radio.

Description
0000 8000 0000 0000 0000 0000 1000 0000 0000 0000 16 The unit address has not been
programmed.
0000 4000 0000 0000 0000 0000 0100 0000 0000 0000 17 A data parity fault has been detected
on the DB25. This usually means there
is a parity setting mismatch between
the radio and the RTU.
0000 2000 0000 0000 0000 0000 0010 0000 0000 0000 18 A data framing error has been
detected on the DB25. This
sometimes means there is a baud rate
mismatch between the radio and the
RTU.
0000 0800 0000 0000 0000 0000 0000 1000 0000 0000 20 Configuration error. The modem
setting is incorrect.
0000 0015 21 Unit is running on back-up battery
power.
0000 0016 22 Standby radio hardware not installed
or available.
0000 0040 0000 0000 0000 0000 0000 0000 0100 0000 25 The 10-volt power regulator output is
out of tolerance. If the voltage is too far
out of tolerance, the radio might not
work.
0000 0020 0000 0000 0000 0000 0000 0000 0010 0000 26 The DC input supply voltage is out of
tolerance. If the supply voltage is too
far out of tolerance, the radio might not
work.
0000 0010 27 LNA current fault (LNA current is out of
range).
0000 0008 28 Total board current fault (total board
current is out of range).
0000 0001 0000 0000 0000 0000 0000 0000 0000 0001 31 The radio’s internal temperature is
approaching an out-of-tolerance
condition. If the temperature drifts
outside of the recommended
operating range, the radio might not
work.
