Tee switch position while redundancy mode is enabled, a mode error will result.
See Table A-1 for a matrix of how OFM use affects operations.

Table A-1 Notes:
This table applies to LPOD 1:1 Redundancy System operation when the
Redundancy State is set to Tx+Rx (ESW=2).
The operational settings in this table – i.e., “0-7 (for the OFM command), and
“0/1” or “0/1-4” for the Online Unit entries, and “0” or “1” for the Offline Unit
entries – conform to the “Description of Arguments” format for remote
command and query operations as they are tabulated in Chapter 5. SERIAL
INTERFACE OPERATION .
The available operational settings for the Online Unit or Offline Unit serial
remote commands are as follows:
•
AMP=0 (the Rx power amplifier is turned OFF), or 1 (the Rx power
amplifier is turned ON)
•
MUT=0 (disabled, i.e., the Tx is NOT MUTED), or 1 (enabled, i.e., the Tx is
MUTED – no data is transmitted). Note that, in the Online Unit, the Tx
Mute setting (MUT) drives that unit’s LNB Bias Tee setting (SBT) – if
MUT=0, then SBT=1; if MUT=1, then SBT=0.
•
AUX=0 (disabled, meaning that the Auxiliary Mute Mode is turned OFF, or
NOT MUTED), or 1 (enabled, i.e., the Auxiliary Mute Mode is turned ON,
or MUTED)
•
SBT=0 (LNB Bias Tee in
Off State
, i.e., MUTED – no data is received), or 1
(LNB Bias Tee is in Through State , i.e., NOT MUTED). Note that, in the
