Patent ID: 8624577

Claim:
A system, comprising: a signal generator operable to transmit electrical power configured as a signal; and a cable set operable to transmit data and to be selectively coupled to the signal generator, the cable set comprising: at least one pair of power delivery wires operable to transmit electrical power; a first adapter proximate a first end of the cable set, the first adapter operable to be coupled to the signal generator to transmit the signal across the power delivery wires; a logic circuit coupled to the power delivery wires of the cable set; and an indicator coupled to the logic circuit and operable to emit light, wherein the logic circuit is operable to: receive electrical power from the power delivery wires, allow at least a portion of the electrical power to continue across the power delivery wires, identify the signal from the signal generator, and pass a portion of the electrical power to the indicator, upon identification of the signal, to cause the indicator to emit light.
