Abstract
The present invention is a system and method for detecting the presence of a cable in a connector. The system may comprise one or more of the following features: (a) a first circuit contact; (b) a second circuit contact; (c) a first capacitive element; (d) an electrical ground; (e) a voltage source; and (f) a logical output. The second circuit contact may be connected to ground. The capacitive element may be driven to ground by connection of the first and second circuit contacts to corresponding cable contacts.
