Abstract

The systems and methods of the present invention provide for conductive emissions communication without requiring dedicated communications wires. The systems and methods have the capability to send digital messages over the same wires that are used to power DC systems. Hardware filter circuits are combined with advanced algorithms in a communications control chip to permit the elimination of the dedicated wires, thereby needing zero additional wires to accomplish the task of digital control.

Claims

1. A method of transmitting a digital communication comprising:

receiving a command signal from an input source to an input module;

transmitting the command signal from the input module directly over a direct current (DC) system power line to an output module;

processing the command signal;

transmitting the command signal over a command line to a load.
