Abstract: A method and system for bidirectional data, power transmission, electrical/electronic fault isolation, and system recovery is shown and described. An exemplary embodiment includes a DC power source, a main power controller (“MPC”) with a MPC microprocessor and an MPC power switcher driver and fault switching control circuit, and a plurality of Nodes connected to the DC power source through conductors that allow both power to be supplied and bidirectional data transfer between a data receiver and the plurality of Nodes. The fault switching control circuit can provide for short detection and isolation (or other fault detection and isolation) without the direct involvement of the MPC microcontroller. The combined use of the conductors for power, data transmission, and fault detection and isolation offers significant advantages over the prior art in terms of weight reduction, system modularity, and complexity, as well as system protection and survivability.
