Mute State MUT= 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

Number of
Unread stored
Events N/A 3 bytes Query only.
Unit returns the Number of stored Events, which
remain Unread in the form of xxx.
Example: <1/NUE?’cr’
>0001/NUE=126’cr’’lf’
NUE= NUE? NUE=xxx
Number of
Unread stored
Statistics N/A 3 bytes Query only.
Unit returns the Number of stored Statistics, which
remain Unread in the form of xxx.
Example: NUS=126
NUS= NUS? NUS=xxx
