<p>PURPOSE: To make an apparatus control correct and easy by connecting a communication control system to a plurality of parameter lamp apparatuses through a data link net work, and providing a plurality of repeaters for monitoring network signals. CONSTITUTION: A control console 24 controls a plurality of parameter lamp apparatuses through a data link 26. The data link 26 is provided with two way paths 38, 40, and the path 38 carries out data communication between each lamp apparatus in the console 24 and a lighting system 20 and another apparatus. The path 40 performs data communication to the console 24 from each lamp apparatus in the lighting system 20. For the purpose of keeping a completeness of an electric command transmitted through the data link 26, repeaters 52, 54, 56, 58 are arranged for amplifying and separating data. Accordingly, a luminous intensity and a color parameter of a lamp apparatus are designated with an operator's selection of a single channel.</p> |
