Abstract:
1. A power controlling device comprising; a power source input; one or more power contacts; one or more digital signal input ports; at least one digital signal detector, the at least one digital signal detector being operatively coupled to at least one of the one or more digital signal input ports and adapted to detect a presence of a digital signal or a lack thereof; a power control relay, the power control relay being electrically coupled to the power source input and at least one of the one or more power contacts, and comprising (i) a first position adapted to energize the at least one of the one or more power contacts based on whether the at least one digital signal detector detects one of the presence of a digital signal or the lack thereof, and (ii) a second position adapted to de-energize the at least one of the one or more power contacts based on whether the at least one digital signal detector detects either the presence of a digital signal or the lack thereof, wherein the one or more digital signal input ports includes a connector adapted to receive an Ethernet signal and the one or more power contacts includes a power outlet adapted to receive a power plug from a power consuming device and the at least one digital signal detector includes a first Ethernet signal detector adapted to detect a presence of transmission activity on an Ethernet connection and a second Ethernet signal detector adapted to detect a presence of power over the Ethernet connection; and a control selector switch adapted to adopt one of either a first position enabling the use of the first Ethernet signal detector or a second position enabling the use of the second Ethernet signal detector.
