to be transmitted and received simultaneously since each signal has its own twisted pair. 5.5 RS-485 OPERATION The PC-COMM+2.ULTRA can be used for both half-duplex (one twisted pair) and full-duplex (two
twisted pairs) arrangements. In half-duplex mode, the link between the TXD and RXD signals is made
internally. The handshaking signals RTS and CTS, although driven by the card, are usually not connected to
