EIA-485 (formerly called RS-485 or RS485) is a standard that specifies the electrical characteristics of the physical layer of the OSI model for 2-wire, half-duplex, balanced transmission line multipoint communication. It is a standard jointly issued by the Telecommunications Industry Association (TIA) and the Electronic Industry Alliance (EIA). Digital communication networks that implement this standard can communicate efficiently over long distances in environments with electronic noise. In a linear multipoint bus configuration, there can be multiple receivers on a network. Therefore it is suitable for use in industrial environments.
