Abstract:
1. An apparatus which integrates power and bi-directional data transmission in order to control the operation of and monitor information from various electrical equipment modules in a control system comprising: a. two conductors of alternating current electrical power including b. at least one controller electrically connected to said two conductors for the generation and transmission of a data signal; and c. at least one addressable controlled device having a device address associated therewith, the controlled device being electrically connected to said two conductors and capable of receiving said data signal generated by said controller; wherein said data signal is comprised of bursts of sinusoidal waves superimposed onto said alternating current electrical power transmitted on said two conductors, said sinusoidal waves being of uniform frequency, said uniform frequency being a higher frequency than the frequency of said alternating current electrical power, said superimposition occurring within a single half-cycle of selected polarity of said alternating current electrical power.
