Select 100 ohm On to turn on the 100 ohm termination resistance across the S/T transmit and receive pairs. Select 100 ohm Off to turn off the 100 ohm termination resistance across the S/T trans- mit and receive pairs.

The SBus Termination resistors are not present on ISU 2x64 units equipped with the integrated NT1 (part numbers 1200051L1 and 1200051L3). Setting the SBus Termination resistance to on or off on these units has no effect on their operation and can be ignored.
