The RS-485 communications standard was introduced in 1983 by the Electronic Industries Alliance (EIA) as a two-wire, half-duplex, multi-drop alternative to the point-to-point RS-232 interface. (RS-485 can also be wired using 4-wires to enable full-duplex communication). However, the EIA RS-485 specification does not stipulate the method for controlling the driver, therefore a number of alternatives have evolved.
