ABSTRACT:
In this system, the units are capable of transmitting and/or of receiving messages in at least a first format by way of a channel (A). Circuitry included in at least one of these units (B, M) are provided for transmitting on the channel (A), in a second format distinct from the first format, a message for putting the other electronic units (M) into operation. Each unit (M) comprises first circuit (102) for interpreting the messages in the second format in order to command the switching on of at least a portion (200, 202; 300, 302) of the circuits of this unit, second circuit (202); (302) for interpreting the messages in the first format in order to command the switching off or to confirm the switching on of at least a portion (200, 202; 300, 302) of the circuits of unit, the second interpretation circuit being part of the circuits whose switching on is controlled by the first interpretation circuit, and a circuit (101) for supplying the first interpretation means (102) independently from the messages transmitted on the communications channel (a).
