ABSTRACT:
A multiplex bus interface enables power and data to be transmitted and received on a two wire bus. Input and output devices operate with transceivers connected to the bus to communicate with each other by placing their data on the bus within specific time slots controlled by a controller, a clock module which broadcasts data to all connected transceivers. A pulsed power waveform provides power to the transceivers and data through pulse width modulation of the pulsed waveform. Data from the transceivers is transmitted during a time slot between power pulses. Data integrity is checked by the initiating input transceiver. Errors are reported at the end of a broadcast cycle. Output transceivers use the data as appropriate for the device and condition being monitored or controlled.
