Claim 0:
1. A system, comprising:
a source for delivering DC power integrated with control data for operating a light emitting diode (LED) within an endpoint, comprising:
a power supply with a source low-pass filter coupled to a supply output and configured to provide the DC power to the supply output;
a source microcontroller configured to receive an external input relating to the control data and to output at a data frequency a first information signal comprising the control data; and
a source modulator coupled to the source microcontroller and configured to generate a first modulation signal, the first modulation signal comprising a first carrier frequency modulated with the first information signal, wherein the first carrier frequency is greater than the data frequency, the source modulator being configured to pass the first modulation signal through a source high-pass filter to the supply output;

a cable configured to communicate the DC power and the first modulation signal from the source and to the endpoint; and
the endpoint positioned remotely from the source for receiving the DC power and the first modulation signal from the cable, comprising:
an endpoint input coupled to the conductor to receive the DC power;
the LED with an endpoint low-pass filter coupled to the endpoint input, the low-pass filter configured to separate the DC power from the first modulation signal to provide the DC power to the LED;
an endpoint demodulator with an endpoint high-pass filter coupled to the endpoint input and configured to demodulate the first modulation signal received within the DC power; and
an endpoint microcontroller configured to receive the control data from the endpoint demodulator and to output signals for controlling operation of the LED based at least in part on the control data.
