Patent ID: 7719133

Claim:
A digital wiring system for vehicles comprising: a synchronization line ( 6 ); a data line ( 7 ) for data transmission and reception; a plurality of multiplexer modules connected in series via the synchronization line ( 6 ) and the data line ( 7 ), said plurality of multiplexer modules at least comprising a first multiplexer module ( 1 b ); and, a second multiplexer module ( 1 b ′); a synchronization generator ( 2 ), which generates a clock signal consisting of pulse trains ( 3 ) separated by rest periods ( 4 ) that represent a at least one multiplexer module identification code, said clock signal is sent to the plurality of multiplexer modules via the synchronization line; being said synchronization generator ( 2 ) regulated in frequency and cycles per sweep; at least one multiplexer module of the plurality of multiplexer modules is connected with at least one electro-electronic device selected from the group consisting of a data transmission electro-electronic device, a data reception electro-electronic device, and a data transmission and reception electro-electronic device; and, the first multiplexer module ( 1 b ) at least comprising: a means for storing at least one multiplexer module identification code; a means for detecting the pulses of the signal received in the multiplexer module via the synchronization line; a means for generating at least one multiplexer module identification code from the detected pulses, said multiplexer module code identification means comprises a counter which performs a count of each clock pulse ( 3 ) of the synchronization signal; a detection decoder that carries out the following actions in the multiplexer module when the generated multiplexer module identification code, obtained from the performed count, and the stored multiplexer module identification code match: activating the multiplexer module during one pulse duration; reading/writing at least one data from/into the data line ( 7 ) during said pulse duration; and, reading/writing a data from/into the outputs/inputs of the at least electro-electronic device connected to the multiplexer module during said pulse duration; being said at least electro-electronic device activated with the data located into the inputs of the at least electro-electronic device connected to the multiplexer module.
