RS-485 Programming for Opt8J
If you intend to do RS-485 communication with Opt8J, please follow the RS-485
programming guide below and also refer to Chapter “Connection Option (Opt8x)
and Cable Wiring” for more Opt8J RS-485 operation details.
The Opt8J supports only 2-wire half-duplex RS-485 communication. Data+/- pins
are served for both data transmitting and receiving, depending on the RTS signal.
The port switch of each port should be set to On position. The port is for
transmitting data if RTS is asserted and for receiving data if RTS is not asserted.
RTS scheme is suitable for any system, including Windows NT and Windows 95/98,
DOS, or UNIX, that permits RTS control from application programs.
