RJ45 Pinout for the RS-485 Port(s) of the RP-V Controllers
This section provides the RJ45 pinout for the RP-V controllers' RS-485 port(s).
The number of RS-485 ports with RJ45 interface differ between the different controller models.
Regarding the differences in the set of RS-485 ports, the RP-V models can be divided into the following two categories:
RP-V-4A and RP-V-5A
Model with “-M” in the product name: RP-V-5C-M
Para obtener más información, consulte RP-V Models .
The RP-V-4A and RP-V-5A models 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.
The RP-V-5C-M model has one RS-485 port with RJ45 interface, which is labeled RS-485 Com A. The RJ45 pinout for RS-485 Com A port is the same as for the other RP-V models.
The wiring recommendations for the RS-485 ports depend on the type of network the ports are used for. Para obtener más información, consulte Communication Port Wiring .
