RJ45 Pinout for the RS-485 Ports of RP-C-16C-F-230V
This section provides the RJ45 pinout for the RS-485 ports of the RP-C-16C-F-230V controller model.
The RP-C-16C-F-230V model has three RS-485 ports with RJ45 interface, which are labeled RS-485 Com A, RS-485 Com B, and RS-485 Com C. The RJ45 pinout is the same for all three RS-485 ports and the same as for the RS-485 Com A port on the other RP-C models. For more information, see RJ45 Pinout for the RS-485 Port(s) of the RP-C Controllers .
The wiring recommendations for the RS-485 ports depend on the type of network the ports are used for. For more information, see Communication Port Wiring .
