The RS422A protocol is an industrial standard for serial communication, developed to address the limitations of RS-232. It defines a balanced communication interface, featuring differential signal transmission for improved resistance to electrical noise and extended transmission distances up to 4000 feet. RS422A allows for higher transmission rates up to 10 Mbps and supports a multi-drop configuration with one transmitter and multiple receivers.
