Abstract
A method and system for providing pulsed power and data from a main control unit to slave units via a first bus. The main control unit has an AC signal generator for providing a plurality of first pulses (P1) on the bus for providing the power to the slave units. Each slave unit is AC-coupled to the bus via a first series capacitor arranged for converting the first pulses (P1) into second pulses (P2). Data communication from the main control unit to the slave units is established by modulating the first pulses (P1), and by demodulating the second pulses (P2). The modulation may be based on Pulse Position Modulation, Pulse Width Modulation, Pulse Count Modulation, Pulse Amplitude modulation. Zero, one or more bits may be communicated per first pulse. Optionally the slave units may communicate to the main control unit via a second bus.
