Wiring Diagrams
The following diagram shows an RS-485 full-duplex bus. The ES-R-2x01B-M has a built-in resistor for
terminating its RxD ± input, which can be enabled using a jumper. The Tx ± lines which are outputs from
the ES-R-2x01B-M would be terminated at the receiver at the other end of the bus as shown. Twisted
pair wires are required for each signal pair.
