1-8 C168P User’s Manual
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.
