Claim 12:
13. A non-transitory, machine-readable, storage device that includes instructions that when executed by controller circuitry in an electric power device controller, cause the controller circuitry to:
supply, via electrical wiring, a periodic voltage to an operatively coupled electric power device;
transmit a forward digital message to the electric power device by encoding digital information in timing edges of the periodic voltage;
transmit a short pattern that allows the electric power device to synchronize to a frequency of the periodic voltage prior to the electric power device transmitting a reverse digital message to the controller circuitry;
perform error detection on the reverse digital message received from the electric power device;
transmit a retry pattern to the electric power device responsive to detection of an error in the reverse digital message; and
receive a retransmitted reverse digital message from the electric power device responsive to the receipt of the retry pattern by the electric power device.
