Switch Bias Tee
SBT=
SBT?
1 byte
numeric
Command or Query.
Sets or returns switching of the bias tee into the through state or into the off state,
in the form x, where:
0=Off State (mute LNB) (DEFAULT)
1=Through State (unmute LNB)
NOTES:
1) The bias tee provides a means of muting the LNB. The SBT state will be
controlled by the amplifier mute state while running in redundancy mode,
but while the unit is not in redundancy mode the bias tee may be set
independently of the amplifier mute state.
2) To send this command the unit must have the bias tee option installed;
otherwise, a mode error will result. A mode error will also result if this
command is sent while the unit is running in redundancy mode.
