Abstract

The present invention provides a device for providing communication through power lines (faig. 2) comprised of multiple conductors by transmitting the data signals through a plurality of the conductors. One embodiment of the present invention may be comprised of a transmit circuit (20) communicatively coupled to a first energized conductor for applying a first voltage signal representing the data to the first energized conductor; the transmit circuit being communicatively coupled to a second energized conductor for applying a second voltage signal representing the data to the second energized conductor; and wherein the second voltage signal is opposite in polarity said first voltage signal.
