Abstract

Circuits, devices, systems and methods for transmitting power and communication signals are described. The invention can include a system for commanding and monitoring the status of a plurality of electrical devices and can include two or more communication modules. A primary communication module can be connected to a DC power source, and can transmit voltage signals over a single conductor, and one or more secondary communication modules can transmit current signals over the single conductor. The communication modules of the present invention can each include an interface for bi-directional communication, at least one MOSFET, an AUSART, and a microprocessor. The communication circuit of the present invention can be a bi-directional communication circuit and can include a connection to a single conductor, an encoder, a decoder, and a least one MOSFET. The present invention can also include a method for transmitting digital data messages and power, and can include monitoring and decoding voltage pulses transmitted from a first communication module and monitoring and decoding current pulses send from at least a second communication module, where the voltage pulses from the first communication module can be used to power at least the second communication module.
