RS-422 Mode

Set the respective switch to OFF position to use RS-422 interface. This means the

port is always ready to transmit and receive data simultaneously (full-duplex).

RS-485 Mode

The Opt8J supports only 2-wire RS-485 communication. Set the respective switch

to ON position to use RS-485 interface. This means the port can transmit data only

when RTS is asserted, and receive data only when RTS is not asserted (half-duplex).

Refer to Chapter “Connection Option (Opt8x) and Cable Wiring” for RS-

422/RS-485 cable wiring, and also to Chapter “Serial Programming Tools” for

Opt8J RS-485 programming details.
