Abstract
An adapter for connecting to a connector in a first direction is provided. The adapter includes a plurality of signal pins, arranged in a loop, a power pin, configured to transmit a power signal to the connector, and a detection circuit, coupled to the power pin and the plurality of signal pins. A feedback signal is provided by the connector in response to the power signal that is transmitted through one of the plurality of signal pins, and an interface of the connector is identified by the detection circuit and a pin order of the adapter is defined by the detection circuit according to the feedback signal.
