Abstract
A communication system between remote locations connected by a common wire conductor where AC power ( ) is supplied from one location to one or more remote locations ( and ). At the remote locations, inductor coil components ( ) and ( ) provide power to an instrument ( ). The AC power is modulated with surface selected discrete frequencies ( ) to operate a specific selected remote location. At the selected remote location ( ), the AC power is rectified and a logic processor detects the discrete frequencies for that location and operates the instrument. Data from the instrument is translated by current modulation ( ) which is demodulated at the one location ( ).
