Abstract
A self-diagnostic circuit includes an electrical conductor configured to multiplex, a first switch interposing the electrical conductor, and a first module crossing the first switch. The first module includes a first receptor antenna associated with the conductor on one side of the first switch, a first emitter antenna associated with the conductor on an opposite side of the first switch, and a first interfacing microprocessor. The first interfacing microprocessor is configured to receive no signal from the first receptor antenna when the first switch is open thus generating a first open signal and a first address signal indicative of the first module and outputting the first open signal and the first address signal to the conductor via the first emitter antenna. The first interfacing microprocessor is further configured to receive a first induced frequency signal from the first receptor antenna when the first switch is closed thus generating a first closed signal and the first address signal indicative of the first module and outputting the first closed signal and the first address signal to the conductor via the first emitter antenna.
