ABSTRACT:
A lighting control system includes a plurality of lighting control modules where each module includes function switches for generating command signals to control light intensity levels to run a plurality of lighting channels connected thereto. A programmable central processing unit transmits the command signals and also generates an ID code indicating a unique identity for each. The light control modules are interconnected on a local area network for carrying the ID codes and the command signals. Each of the lighting control modules is programmable for selecting predetermined ID codes whereby command signals generated by selected control modules may be executed by other control modules.
