Arguments for
Command or
Query
1 byte
Command or Query.
Sets or returns offline mute in the form x, where:
0=Disable (Not Muted)
1=Enable (Muted)
2=Mute RX
3=Mute Tx
4=Mute Rx+LNB
5= Mute Tx+LNB
6=Mute Tx+AMP
7=Mute Tx+LNB+AMP
NOTE: LNB Voltage of Online unit shows on Status page of Offline unit when Offline Mute is set to 4 or 5. This is
caused by voltage feedback from Online unit to Offline unit via RF splitter.
COMMAND EXAMPLE: <0001/OFM=1{CR}
1 byte
Command or Query.
Sets or returns the Redundancy Online status in the form x, where:
0=Offline (Query only) (SEE NOTE 2)
1=Online
NOTES:
1) The ONL query always returns an online response if the unit is not running in redundancy mode. If redundancy is
enabled then the query will indicate the position of the Tx waveguide switch that enables one of the units to be
connected to the antenna.
2) Sending ONL=0 will not generate a syntax error; however setting ONL to zero will not cause the unit to go offline.
The online status is determined by the Tx waveguide redundancy switch position, and only the offline unit may
drive the switches. Instead of sending ONL=0 to the online unit the ONL=1 command should be sent to the offline
unit to generate a redundancy switchover.
COMMAND EXAMPLE: <0001/ONL=1{CR}
96 bytes
Query only.
alphanumeric
Returns the Comtech EF Data part number of the unit. This part number is the unit's DOTCODE at the time of
manufacture. The DOTCODE may be up to 96 printable ASCII characters long.
EXAMPLE: <0001/PNM?{CR}
