Multiaddress remote control of vehicular accessories without microprocessors

U.S. Patent Number: 5394400

Abstract: A multiaddress control system for remotely controlling accessories in a vehicle utilizes a simple encoder and decoders to perform functions previously performed by microprocessors and bus drivers. A transmitter station has an encoder for station addresses and commands that are received from manual switches. The addresses and commands are sent to all of the receiver stations simultaneously on a two-wire common signal bus. The receiver that has been addressed accepts the command and acts upon it. Every word is transmitted twice, and the receivers compare the two transmitted words. Only if the words match does an addressed receiver carry out the command.
