Alarm mask conditions. If the mask value for a certain
parameter is set to fault then a fault condition will be
registered if specified hardware conditions are not met.
If the mask value is set to alarm then a fault condition
will only appear to be an alarm that will not trigger a
switchover in a redundant system. If the mask value is
set to masked then the fault will never be reported to
the user.
Form of: abcde
Where:
0 = Fault, 1 = Alarm, 2 = Masked
a = Low Forward RF Power
b = External Reference Lock detect
c = Fan Speed
d = LNB Current Detect
e = LNB 22V Power Supply
Example: <1/MSK=22111'cr'
>0001/MSK=1'cr''lf'
Default Value: 22111
1 byte Command or Query.
Mute the unit, where:
0 = Disable (Not Muted)
1 = Enable (Muted)
2 = Unit muted due to AUX mute signal. This value is
only shown in the response to a query, and cannot be
given as a command. When MUT returns a 2 it
indicates that one of the "hardware" mute conditions is
present. For example an auxiliary mute could be
present if the auxiliary mute has been enabled, and
the signal to unmute the unit is not provided.
Additionally, certain faults can generate a hardware
mute such as the BUC lock detect, the LNB current
draw (if enabled by the user), or the LNB voltage (if
enabled by the user). If MUT returns an unexpected
value of 2 then check the active faults, and the status
of the auxiliary mute.
Example: <1/MUT=1'cr'
>0001/MUT=1'cr''lf'
Default Value: 1
