The following diagram shows an RS-422 full-duplex bus with handshaking signals connected. The ES-U-
xxxx-x has built-in resistors for terminating its RxD +/- and CTS +/- inputs, which can be enabled using
jumpers. The TxD +/- and RTS +/- lines which are outputs from the ES-U-xxxx-x are terminated at the
receiver at the other end of the bus as shown. Twisted pair wires are required for each signal pair.
