1 byte Command or Query.
The LPOD output will automatically be muted if one of
the following fault conditions occurs: BUC lock detect
fault, LNB current fault (see Note), LNB voltage fault
(see Note). If auto fault recovery is enabled, it will
cause the output return to its pre-fault mute condition if
all faults are cleared. If disabled, the output will remain
muted even if all faults are cleared.
Example: <1/AFR=1'cr'
>0001/AFR='cr''lf'
Note: these faults can be user defined as faults,
alarms, or masked (see MSK command for more info).
Default Value: 1
1 byte Command or Query.
Turns ON or OFF the RF power amplifiers.
0 = Off
1 = On
Example: <1/AMP=1'cr'
>0001/AMP='cr''lf'
Note: turning the amplifier off will disable the +10V
supply, and mask it during fault checking.
Default Value: 0
5 bytes Command or Query.
Valid attenuation level (00.00 to 20.00), in dB, in 0.25 dB
steps as factory default. This value is not copied to the
offline unit in a redundant system, but will be added to
the attenuation value upon a switchover. This provides a
unit specific fine-tune to maintain power levels
appropriately in a redundant system.
Example: <1/AOF=12.25'cr'
>0001/AOF='cr''lf'
Default Value: 00.00
