• Proper programming of the radio’s operating parameters, especially
Operating Mode (
MODE), Network Address (ADDR), and interface
Baud Rate (
BAUD). For TransNET 2400 check the sub-band (BAND).
• The correct interface between the radio and the connected data
equipment (proper cable wiring, data format and timing).
• In store-and-forward systems there are several areas that should be
checked or evaluated:
• Look for duplicate
XADDR values on MODE M and MODE X radios.
Duplicates will cause failures unless the radios are too far apart to
hear each other.
• Check for errors in the synchronization qualifiers,
XPRI and XMAP,
on corresponding Remote radios.
•Verify
SAF is enabled at the Master radio.
9.1 Alarm Codes
When an alarm condition exists, the transceiver creates an alarm code. These
codes can be very helpful in resolving many system difficulties.
Checking for Alarms—STAT command
To check for the presence of alarms, enter
STAT. If no alarms exist, the
message
NO ALARMS PRESENT appears at the top of the display.
If an alarm does exist, a two-digit alarm code (00–31) is displayed, and it is
identified as a major or minor alarm. A brief description of the alarm is also
given. Alarm codes and their meanings are listed in Table 23.
If more than one alarm exists, the word
MORE appears at the bottom of the
screen; additional alarms can be viewed by pressing .
Major Alarms versus Minor Alarms
Major alarms report serious conditions that generally indicate a hardware
failure, or other abnormal condition that will prevent (or seriously hamper)
further operation of the transceiver.
With the exception of alarm code 00 (network address not programmed),
major alarms generally indicate the need for factory repair.
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.
