RS-422, or Electronic Industries Association (EIA) Recommended Standard 422, is a full duplex hardware protocol that uses two pairs of differential conductors, one set for transmitting (Tx) and one receiving (Rx). These differential pairs are often twisted to travel long distances, up to 1,500 meters, with good robustness to noise, which make this protocol attractive for industrial applications. This multi-drop protocol can support multiple slave devices on one bus at speeds up to 500 Kbps. Implementing an addressing scheme, such as RS485, over RS422 hardware protocol allows the creation of a multi-point network design.
