The first line of the response to the
indicating whether or not alarms are present. The second line is a hexadecimal
numeric code representing the system alarm state. Examples of responses are:
NO ALARMS PRESENT
CODE: 0000 0000
MINOR ALARMS PRESENT
CODE: xxxx xxxx
MAJOR ALARMS PRESENT
CODE: xxxx xxxx
Each bit of the hexadecimal response code represents a unique alarm event.
The first 4-digit number indicates major alarm conditions; if there are no major
alarms, this number is 0000. The second 4-digit number represents minor
alarm conditions; if there are no minor alarms, this number is 0000.
Code values for individual major alarm conditions are given below:

command is a simple message
ALARM
Alarm Conditions
Description
The hardware configuration disagrees with the software.
Model number is not programmed.
Authorization fault (radio option not available).
One or both of the programmable synthesizers is reporting
an "out of lock" condition.
A/D fault
One or more of the radio's internal voltage regulators is
reporting a failure. The radio will not work.
The system has not been calibrated. Factory calibration is
required for proper operation of the system.
The radio was unable to properly program itself to the
appropriate defaults. There may be a hardware problem.
The receiver timed out.
The transmitter timed out.
Output power fault.
Description
The unit address has not been programmed.
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.
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.
Configuration error. The modem setting is incorrect.
