Abstract
An apparatus for converting a low voltage alternating current (AC) wiring circuit to a high speed data communications link, comprising a primary coupling circuit and a secondary coupling circuit. The apparatus provides low voltage AC power to a data device and couples data signals between the data device and the AC power line via the converted low voltage AC wiring circuit. An example is provided for retrofitting a door chime system to a high speed data link such as a video camera system.
