STARTECH RS-422 Adapter - A point-to-point serial communications standard that defines a differential (or balanced) interface using two separate wires for each signal Simple Type: Adapter

RS-422 is a point-to-point serial communications standard that defines a differential (or balanced) interface using two separate wires for each signal. Differential signals on twisted pair cables allow very high data rates in environments despite electrical noise and varying ground potentials. Signal levels are compatible with RS-485 so equipment is often configurable for either standard. The RS-422 standard does not define mechanical connections or assign pin numbers, but often DB-9 connectors are used. Typically, two wire pairs are used to accomplish two-way communications. In some cases hardware handshake lines (RTS, CTS) are included in an RS-422 interface. Each signal requires one twisted pair.
