RJ45 Pinout for the RS-485 Port(s) of the RP-C Controllers
This section provides the RJ45 pinout for the RP-C controllers' RS-485 port(s).
The number of RS-485 ports with RJ45 interface and the RJ45 pinout differ between the different controller models.
Regarding the differences in the set of RS-485 ports and RJ45 pinout, the RP-C models can be divided into the following three categories:
Models with “-F” in the product name:
RP-C-12A-F-24V, RP-C-12B-F-24V, RP-C-12C-F-24V, RP-C-16A-F-230V, RP-C-16B-F-24V, and RP-C-16B-F-230V
Models with “-M” in the product name:
RP-C-12A-M-24V, RP-C-12B-M-24V, and RP-C-16A-M-24V
RP-C-16C-F-230V model
Pour plus d'informations, voir RP-C Models .
The RP-C models with “-F” in the product name have two RS-485 ports with RJ45 interface, which are labeled RS-485 Com A and RS-485 Com B. 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. Pour plus d'informations, voir Differences Between RP-C Hardware Versions .
The RP-C models with “-M” in the product name have one RS-485 port with RJ45 interface, which is labeled RS-485 Com A. The RJ45 pinout for this RS-485 port is the same as for the RS-485 Com A port on the other RP-C models.
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 for these three RS-485 ports is the same as for the RS-485 Com A port on the the other RP-C models.

The wiring recommendations for the RS-485 ports depend on the type of network the ports are used for. Pour plus d'informations, voir Communication Port Wiring .
