Description of Arguments
Command or Query.
Set or return 1:1 operational mode in the form x, where:
0 = Unit is in Manual mode
1 = Unit is in Auto mode.
NOTE: In Manual Mode, all fault relays are forced to the non-faulted condition. This allows an online unit to be
configured without undesired switchover to a backup unit (Changing Rx frequency would normally cause the
online unit to unlock and a switchover to the backup modem would occur).
Command only.
There are no parameters associated with this command. In a 1:1 switch environment, this command forces an
online unit offline. If the unit is offline, then no action is taken.
Notes:
1. The 1:1 redundancy system must be installed!
2. Both online and offline units must be in Manual Mode for this command to function.
3. If the 1:1 redundancy system is not installed, then the command will return FSW?
4. If the unit is offline, then the command will return FSW?
Example: FSW=
Query only.
Return 1:1 online/offline status in the form x, where:
0 = Unit is offline
1 = Unit is online
Example: RED?1 (indicating the unit is online)
Command or Query.
Sets or returns 1:N operational mode in the form x, where:
0 = Unit is not enabled for 1:N switch operation.
1 = Unit is enabled for 1:N switch operation.
Example: R1N=1 (indicating the unit is enabled for 1:N)
Query only.
Returns 1:1 switch status in the form x, where:
0 = Unit is not connected to a 1:1 switch
1 = Unit is connected to a 1:1 switch
Example: R11?0 (indicating the unit is not connected to a 1:1 switch)
