or Query
1 byte Command or Query.
Sets or returns automatic fault recovery in the form x, where:
0=Disabled
1=Enabled (DEFAULT)
NOTES:
1) If auto fault recovery is enabled, it causes the output to return to its pre-fault
mute condition if all faults are cleared. If disabled, the output remains muted
even if all faults are cleared. The LPOD output automatically mutes if one of
the following fault conditions occur:
• BUC lock detect fault
• LNB current fault
• LNB voltage fault
2) These faults can be user defined as faults, alarms, or masked (see MSK
command for more info).
COMMAND EXAMPLE: <0001/AFR=1{CR}
1 byte Command or Query.
Sets or returns the RF power amplifiers status in the form x, where:
0=Off (DEFAULT)
1=On
NOTE: Turning the amplifier off disables the +10V supply, and masks it during
fault checking.
COMMAND EXAMPLE: <0001/AMP=1{CR}
5 bytes Command or Query.
Sets or returns the attenuation offset level in the form xx.xx, where:
xx.xx=00.00 (DEFAULT) to 20.00, in dB, in 0.25 dB steps
NOTE: This value is not copied to the offline unit in a redundancy system, but is
added to the attenuation value upon a switchover. This provides a unit-specific fine-
tune to maintain power levels appropriately in a redundancy system.
COMMAND EXAMPLE: <0001/AOF=12.25{CR}
