Apparatus for determining and reporting identification information relative to devices pluggable to a central unit.

摘要

An apparatus for determining and reporting identification information relative to devices which are pluggable to a control unit through connectors (2-1 to 2-2) of a connecting card comprises a digital to analog converter (36) which receives the identification information from the connectors to which devices are plugged, at its inputs. The converter generates an analog voltage therefrom, the value of which is representative of the identification information of the plugged devices. The analog voltage is transmitted to the central unit 8 which comprises an analog to digital converter (52) for measuring and deducing the configuration of the plugged devices from the measured value. This apparatus allow the identification information to be reported to the central unit in an efficient way, more specifically when the connecting card is remote from the central unit.
