RJ45 Pinout for the RS-485 Ports of the RP-C Controller
This section provides the RJ45 pinout for the RP-C controller's two RS-485 ports.
The RS-485 ports are labeled RS-485 Com A and RS-485 Com B. Więcej informacji zawiera RP-C Communication Ports .
The RJ45 pinout differs only with regards to pin 2 between the two RS-485 ports.
For the RP-C-12A-F-24V, RP-C-12B-F-24V, RP-C-12C-F-24V, and RP-C-16A-F-230V controller models, the rating for the RS-485 Com A port, the RJ45 pinout for the RS-485 Com B port, and the labeling of the two RS-485 ports differ between different hardware versions of the controllers.
