NOTE: Switch positions 5-9 are not used.

Note the following:

The FT85041 transmitter/FR85041 receiver allows data translation between RS-232 and RS-422 signal levels. Consequently, the Data Selection switch can be set to 0 (RS-232) on the transmitter and to 1 (RS-422) on the receiver. Conversely, the Data Selection switch can be set to 1 (RS-422) on the transmitter and to 0 (RS-232) on the receiver.

If you wish to change the data communication setting after the FT85041 transmitter/FR85041 receiver has been powered on, power off the transmitter/receiver, change the data communication setting, and then power on the transmitter/receiver again.
