ABSTRACT:
Improvements are disclosed to systems adapted for the control of automated or variable parameter lighting fixtures and devices capable of varying a plurality of beam parameters such as the pan, tilt, size, shape, color, and focus on the basis of desired adjustments stored by the control system for each of a plurality of desired lighting effects. Such a control system is provided with a means, such as a port, for coupling to an external device having at least one output and capable of a plurality of conditions each of which may be used to identify a different lighting effect so that the operation of the control system and the external device may be synchronized. One such external device may be a lighting memory controller adapted for the adjustment of desired intensity values and coupled to dimmers, such that the selection of a desired lighting effect by one such control system can automatically cause the other such control system to recall any stored adjustments for the same lighting effect, whereby the operation of large numbers of conventional lighting fixtures can be synchronized with that of automated fixtures while permitting the use of a separate control system for each.
