Abstract

The invention is a power bus data transmission system (10) and method of data transmission. An existing system power bus functions (22) as the backbone data transmission network for transmitting data transmissions between at least one new device and at least one other device in an existing system (11) without the addition of new wiring to transmit the data transmissions. Assemblies of processors (40), device interfaces (50) and modems (130) may be used to connect the devices (12, 14, 16, 18) to the system power bus.
