Abstract
A stage lighting system has a plurality of automated lamp units which can vary the parameters of a light beam for pan, tilt, brightness, intensity and size. A remote console controller system is connected to each of the lamp units via an intelligent data link system. Each of the lamp units includes a microprocessor and a memory. Control programs for driving each of the lamp parameters are stored in the memory and are executed by the lamp microprocessor. The console controller system includes a plurality of controllers, each of which can alternatively or additionally control the operations of the lighting system. The intelligent data link system includes a plurality of signal repeaters, each of which includes a microprocessor and an associated memory for controlling the communication of data and for cooperating in error detection and correction.
