RS422/RS485 Communication Topologies and the Versa-Tap RS422/RS485 Sniffer

Full Duplex 4-wire RS422/RS485 Point to Point Connection The simplest and most common RS422/RS485 interface is the 4-wire full-duplex point to point connection shown below. With this signaling arrangement, communication is functionally similar to that of RS232 with the improved performance provided by differential signaling.   Full-Duplex Point to Point Connection   Half Duplex 2-wire…
