ABSTRACT:
The present invention provides a system of and a method for multiple transmitters to communicate data over a single uni-directional communication bus. In one form of the present invention, a data communication system using time-domain multiplexing includes a uni-directional current-modulated communication bus, a plurality of sensors coupled to the communication bus, at least one of the sensors capable of detecting the data transmission of a sensor outside of the current loop of the first sensor, the sensors also capable of transmitting data on the communication bus using current loop modulation. In another form of the present invention, a method of transmitting data on a uni-directional communication bus is provided. The method includes the steps of enabling a first device to transmit a data signal on the communication bus, the data transmission followed by an idle period, and the first device including a current sensor; enabling a second device to detect the first device's data transmission and the idle period; and enabling the first device to transmit data upon detecting the idle period, the first device positioned in a first current loop and the second device positioned in a second current loop outside of the first current loop, the second current loop passing through the current sensor of the first device.
