Abstract
A data and power transmitting/receiving system applicable to a home automation system. Plural terminal units and associated communication units are connected via a common signal bus. Each terminal unit may operate an electrical load to be controlled remotely, and may include control switches for operating such loads at a number of remote locations. Each communication unit generates an n-bit data signal, each bit corresponding to the desired function of a corresponding terminal unit. A sync signal is combined with the data signal in time sequence such that the respective communication units can identify which signal operates which terminal unit. The sync signals also can supply DC power to ther respective communication units.
