Abstract
Abstract But interconnection device in a data transmission network where each bus connects multiple modules or stations, characterized by the fact that it comprises electronic comparator (51) for receiving the voltages of various buses and delivering a corresponding voltage to the extreme voltage of various input voltages. A correction device (52) applies a slight deviation to the extreme voltage and a distribution circuit (53) provides the corrected voltage to various buses (1 to 4).
