RS-485 is set up for four-wire communication by default. To connect a 2-wire device, you will need to short the transmit and receive signals together on the RS-485 port. Note that this is necessary to connect RJ45 (8-pin modular jack) ports to RJ50 (10-pin modular jack) ports. Follow the instructions below.
