  2. RS 232 Serial Communication • A simple, universal, well understood data interface was introduced in 1962 • Max 256 kbps, line length 15 M (50 ft) or less • Signal representation (bipolar: +3 to +15v, -3v to –15v) • MARK (negative voltage) – idle or off state • SPACE (positive voltage) – active or on state Prof. Paul Lin
