5 bytes Command or Query.
Valid attenuation level (00.00 to 20.00), in dB, in 0.25
dB steps as factory default.
Example: <1/ATT=12.25'cr'
>0001/ATT='cr''lf'
Default Value: 10.00
1 byte Command or Query.
Enables or disables the auxiliary mute mode.
0=Disabled
1=Enabled
Example (AUX Mute Enabled): AUX=1'cr'
Note: When enabled, the mute control input on the
remote com connector must be grounded to UN-MUTE
the unit. Otherwise, the unit will be muted, and if a mute
query is given (MUT?) the response will be MUT=2 to
indicate a hardware controlled mute is present.
Aux mute is one of several hardware mute states that
can cause a MUT=2 to be reported. See the MUT
command for more info on mute states.
Auxiliary mute supersedes the user mute state so if the
command MUT=1 is sent, then AUX=1 is sent, and the
user shorts Pin K to Pin S on the discrete control
connector then the RF mute will be disabled (MUT=0).
Default Value: 0
None Command only.
Instructs the LPOD to clear all Stored Alarms. This
command takes no arguments.
Example: <1/CAA='cr'

command takes no arguments.
Example: <1/CAE='cr'
>0001/CAE='cr''lf'
