Abstract

A central station generates grouped clock pulses in recurring selection cycles, separated from each other by an extended control pulse (or pulse gap); particular loads are associated with particular counts of a central counter in the central station. The separate counts of the counters are connectable to a control bus of a combined power bus, clock bus and control bus cable system which passes by all the loads associated with the power supply. At the loads, receiving counter step in synchronism with the pulses occurring during the selection cycle. Specific loads are assigned specific count numbers and when coincidence between the count, as stepped by the counter and a pulse on the control bus, (as controlled by a switch setting at the central station) occurs, switching function, such as connection, or disconnection is effected at the load. An additional answer back line may be included in the cabling system, likewise connected upon stepping of the counter and recognition of the specific count associated with any receiver, connecting the receiving reply signal generator for example a sensor or transducer to an indicator at the central station, specific indicators being associated with specific switches at the central station.
