摘要: In one embodiment, an apparatus includes a circuit coupled to line, where the may power device, and is transmitted device over line as pulse-width modulated signal. The set duty cycle of signal in order transmit determined level device. vary frequency data while fixed continue A variation be detectable by represents at least portion data.
