By applying such techniques as single chip microcomputer, network communication and long-range vision, a master/slave distributed long-range LED display control system based on the RS-485 bus has been developed. It can simultaneously monitor and control many LED displays distributed in different distant places and dramatically refresh their display contents, which can also be previewed on the PC. The design principle, hardware construction and software design for the said system is present. The telecommunication principle and method for the multi-LED display are given in detail.
