Driver Boards

The SHOWGUN® fixture is designed with two basic types of motor driver boards. A driver board is

interchangeable with other boards of its type. Standoffs and contact screws allow for position- specific board addressing. The fixture will not function correctly if contact screws are missing from driver boards.

2-Phase Boards

Four 2-phase boards control the motors for all CMY color flags, Soft Edge Flags, Gobo Indexing and Rotation as well as Zoom, Focus and Iris functions. These boards are located together on a bracket inside the electronics housing behind the display panel. Boards 1 and 2 are on the front side of the bracket. Boards 4 and 8 are on the backside.
