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.
