Abstract
A half-duplex communication system includes a first half-duplex transceiver. The first half-duplex transceiver includes a first microprocessor and a current sensor connected to an input of the microprocessor, and the half-duplex transceiver is coupled to a first and second voltage source. The first voltage source is at a first voltage level and the second voltage source is at a second voltage level. The first microprocessor is configured to transmit data by alternatively connecting the first voltage source and the second voltage source to a conductor and to receive data in the form of pulses of current on the conductor detected by said current sensor.
