A system for remotely controlling electrical devices includes a plurality of identical modules which can be made as multiple copies of an integrated circuit chip. Each chip includes logic for recognizing a code, the logic being programmable by EEPROMs so that each chip can be set to recognize a unique address code. The modules can be connected to input or output devices, or both. All modules are interconnected by no more than four wires. A clock pulse source is connected to the system, the source being periodically interrupted to synchronize the system when the clock pulses restart.

A controller system comprising the combination of a control location having a plurality of programmable control modules, each said module having an input device connected thereto for supplying to said module an input signal capable of having only two states; a plurality of programmable controlled modules, each said controlled module having an output device connected thereto for performing a specified function, said controlled modules being physically separated from said control location; each said control and controlled module being substantially identical to each other said control and controlled module apart from programming, a cable having no more than four operative wires interconnecting all of said control modules and all of said controlled modules and spanning the physical separation therebetween; means connected to one of the wires in said cable for producing and delivering to said control and controlled modules a sequence of clock pulses of uniform duration periodically interrupted by an interval of no clock pulses to synchronize the operation of said modules; and encoding/decoding means including a clock pulse counter in each of said control and controlled modules programmed to permit each said module to respond to a preselected count of said counter to thereby assign to each said module a unique code and thereby uniquely operatively associate each of said control modules with preselected one or ones of said controlled modules programmed to respond to the same count so that a control module responds to an input signal supplied to said control module by the input device connected thereto by producing and coupling to said four-wire cable a control signal at the count unique to said control module and so that said control signal generated by said one control device is recognized and acted upon by only said selected one or ones of said controlled modules programmed to respond to the same count to produce output signals for causing said output device or devices connected thereto to perform said specified functions.
