7-1-1. System Block Description
Main Board : Receives various video signals and control signals to control or operate the DMD board, cooling fan,
SMPS board, lamp, and the ballast. It also processes video signals and transmits them to the DMD
board.
DMD Boar : Supplies power controlled by the Main board to the DMD panel to operate the DMD panel and transmits
the color wheel and sensor control signals to the Color Wheel and the Sensor board.
Ballast : Operates the lamp.
SMPS : Receives external AC power and supplies voltage to the Main board and the Ballast.
