Description of Arguments
d = Rx 2 Traffic status (future):
0=Rx Traffic OK
1=Demodulator unlocked
2=Rx FIFO Overrun
e = Change in modem fault status since last poll
0=unchanged
1=changed
f = Change in modem configuration since last poll
0=unchanged
1=changed
xx=spares
Command only.
This command takes no arguments. Forces the unit to toggle the
Unit Fail relay to the "fail" state for approximately 500ms.
If the unit is a 1:1 pair and it is currently the 'Online' unit, this forces a
switchover so the unit will then be in 'Standby' mode.
The command is always executed by the unit regardless of whether it
is stand-alone, or in a 1:1 pair.
Command or Query.
Monitor Port State control, where:
0=Off
1=On
Example: MOP=1 (Monitor Port On)
Query only.
Returns the redundancy state of the unit, where:
0=Offline
1=Online
Example: RED=1 (which is Online)
Query Only.
Returns the value of the Rx signal level, in dBm, between –25 and
–55 dBm with a tolerance of +/- 5 dBm. Resolution = 0.5dB.
Note the following:
If in the range of –25 to –55dBm, returns SL1=-xx.y
If >–25dBm, returns SL1=GT-25 (GT = 'greater than')
If <–55 dBm, returns SL1=LT-55 (LT = 'less than')
Example: SL1=-45.5 (indicating –45.5 dBm)
Query only.
Returns the value of the internal temperature sensor (in degrees C), in
the form of xxx.
Example: TMP=+26
A–22
