Offline Mute OFM= 1 byte Command or Query.
Mute the unit when it is offline, where:
0 = Disable (Not Muted)
1 = Enable (Muted)
Unit will automatically mute its RF output when it is
offline if OFM is enabled. Otherwise, the unit will
remain at its previous mute state regardless of online
/ offline status.
Example: <1/OFM=1’cr’
>0001/OFM=1’cr’’lf’
Default Value: 1
OFM=
OFM?
OFM* OFM? OFM=xxx
Online Status ONL= 1 byte Command or Query.
Online status (applies only to redundancy), where:
0 = Offline (Query only) (see Note)
1 = Online
The ONL query always returns an online response if
the unit is not running in redundant 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.
Example: <1/ONL=1’cr’
>0001/ONL=’cr’’lf’
Note: 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 redundant 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 redundant
switchover.

Part Number N/A 96 bytes
alphanumeric Query Only
The PNM query will return the DOTCODE string that
was loaded into the unit.
Example: <1/PNM?
