Arguments
for Command
(Note that all arguments are ASCII numeric codes from 48 to 57)
or Query
5 bytes Command or Query.
Sets or returns the attenuation level in the form xx.xx, where:
xx.xx=00.00 to 20.00, in dB, in 0.25 dB steps
Default value: 10.00
COMMAND EXAMPLE: <0001/ATT=12.25{CR}
1 byte Command or Query.
Sets or returns the auxiliary mute mode in the form x, where:
0=Disabled (DEFAULT)
1=Enabled
NOTES:
1) 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.
2) 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.
3) Aux 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; the RF mute will then be disabled (MUT=0).
COMMAND EXAMPLE: <0001/AUX=1{CR} (enables Aux Mute)
