1:1 Operational
Mode
ASW ASW? 1 byte, value of 0
or 1
Command or Query.
Sets or returns 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).

1:1 Force Unit
Offline
FSW= FSW? 0 bytes Command only.
This command takes no arguments. 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?

N/A RED? 0 bytes Query only.
Return 1:1 online/offline status in the form x, where:
0=Unit is offline
1=Unit is online
EXAMPLE: <0/RED?
>0000/RED=1 (indicates the unit is online)
N/A RED=x
1:N Redundancy
Enable
R1N= R1N? 1 byte, value of 0
or 1
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: <0/R1N=1 (indicates the unit is enabled for 1:N)

N/A R11? 1 byte, value of 0
or 1
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: <0/R11?
>0000/R11=0 (indicates the unit is not connected to a 1:1 switch)
N/A R11=x
