Abstract

A system for the transmission of data, particularly for use on board motor vehicles, comprises a main unit M and one or more peripheral units S. When the system is in the stand-by position, an electronic switch 14 in at least one peripheral unit S maintains the data transmission line L which connects the various units substantially short-circuited to earth. A reactivation command 10 applied to the peripheral unit S determines the opening of said electronic switch with the consequent transmission towards the main unit M of a signal which produces the reactivation of the system as an effect of the operation of the means of supply 8 envisaged in the main unit M. (Sole figure). <IMAGE>
