Force Back-Up
State
FBU= 1 byte,
value of 0, 1, 2
Command or Query.
For 1:2 systems only (sent only to the BU unit).
Force one of the online units to be a backed up for maintenance and test purposes, in the form
x, where:
0 = Force BU OFFLINE and place system in AUTO mode.
1 = Force SSPA 1 OFFLINE and place system in MANUAL mode.
2 = Force SSPA 2 OFFLINE and place system in MANUAL mode.

N/A N/A
Online Status N/A 1 byte,
value of 0,1
Query only.
For 1:1 systems only (sent to both units).
Returns the online status in the form x, where:
0 = OFFLINE
1 = ONLINE

Configure
Redundancy
Amp
CRA= 1 byte
value of 0,1
Command or query.
Permits configuration of the redundancy amplifier mode in 1:1 and 1:2 redundancy systems, in
the form x, where:
0 = Disabled - the offline unit's amp state will follow the online unit's amp state (Default).
1 = Enabled - the offline unit's amp state will be Off, if it becomes the online unit, then its amp
state will be On. This affects all units in the redundancy system.
Note: The same CRA value should be sent to all units in the redundancy system.
