Indicates the condition of the summary fault relay.
Where:
0 = Not Faulted (SumFLT_COM J6 pin K is not
connected to SumFLT_NC J6 pin M)
1 = Faulted (SumFLT_COM J6 pin K is connected to
SumFLT_NC J6 pin M)
Example: <1/SFS?
>0001/SFS=0'cr''lf'

numeric Enables or disables the external reference not present
mute. When the XRM command is enabled the unit will
mute if an external reference oscillator is not detected.
Where:
0 = Disable
1 = *Enable
Example: <1/XRM=1
*Note: To enable this command the internal reference
oscillator option must be installed; otherwise, a mode
error will result.
1 byte Command or Query.
numeric Switches the bias tee into the through state, or into the
off state. The bias tee provides a means of muting the
LNB. The SBT state will be controlled by the amplifier
mute state while running in redundant mode, but while
the unit is not in redundant mode the bias tee may be
set indepently of the amplifier mute state.
0 = Off State (mute LNB)
1 = Through State (unmute LNB)
Example: <1/SBT=1
Note: 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 redundant mode.
