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