Wiren Board 4 controllers are equipped with two RS-485 ports. One of them is galvanic insulated, the other one is not. If the RS-485 network is quite large, it is better use the insulated port for connection. Lines A and B are connected to A and B terminals, respectively. The signal ground (if any) must be connected to the GNDiso terminal. | Wiren Board 4 controllers are equipped with two RS-485 ports. One of them is galvanic insulated, the other one is not.
