ABSTRACT:
In a motor vehicle air conditioning installation comprising a central control unit (12), a computer network (14) connected to the central control unit (12) and a plurality of peripherals (101, 102, 103, . . . , 10n) connected to nodes (N1, N2, N3, . . . , Nn) of the computer network, the peripherals are connected in series via a common conductor (18). The installation comprises means (120) for inputting at the level of each peripheral an electric signature on a common conductor, means (130) for detecting an electric signal depending upon the electric signatures of the peripherals situated upstream on the common conductor (18), means for generating a data item representing the relative position of the peripheral on the basis of the electric signal detected, and means for identifying the node of the network to which it is connected on the basis of the relative position data item generated. The identification of the node of the network permits the assignment of an address or monitoring of the connection of the peripheral from the central control unit.
