Abstract
A plug-in detection module includes an impedance network for producing a plug-in signal in response to a supply signal that varies when one of a plurality of plug-in receptors is coupled to a plug connector and when one of the plurality of plug-in receptors is decoupled. A reference signal generator generates a reference signal having a plurality of reference signal values. A comparator generates a detection signal when the plug-in signal compares favorably to the reference signal. A processing module detects which of the plurality of plug-in receptors have a plug connector coupled thereto.
