1. A BaseT Ethernet device configured to interrogate for predetermined response via at least one direct current (DC) signal, the Base T Ethernet device comprising:
- an Ethernet jack connector of the BaseT Ethernet device, the Ethernet jack connector comprising first and second pairs of contacts, each of the first and second pairs configured to carry BaseT Ethernet communication signals wherein the first pair of contacts consists of a transmit pair of the Ethernet jack connector and wherein the second pair of contacts consists of a receive pair of the Ethernet jack connector; and
at least one direct current (DC) supply of the BaseT Ethernet device, the at least one direct current (DC) supply coupled to at least one of the contacts of the first pair of contacts and at least one of the contacts of the second pair of contacts of the Ethernet jack connector,the BaseT Ethernet device configured to provide or receive at least one direct current (DC) signal via at least one of the contacts of the first pair and configured to receive or provide the at least one direct current (DC) signal via at least one of the contacts of the second pair, the predetermined response carried by at least two different magnitudes in the flow of the at least one direct current (DC) signal.
