RS-422 - Network Encyclopedia

RS-422 is also known as TIA/EIA-422.

RS-422 is a high-speed full-duplex serial interface that uses balanced lines and has more immunity from noise than the RS-232 interface.

RS-422 was originally designed to supersede RS-232, but they now coexist. RS-422 typically transmits data at rates of 230 Kbps, but the speed can be increased to around 1 Mbps.
