3. Product Overview The projector consists of DLP projector controller, Lamp controller, Power supply system, and System cooling controller. The DLP controller captures digital PC data and video data and then converts them into the DMD display device. The Lamp controller dominates the lamp’s power and synchronizes its frequency with color display sequence. The Power supply unit controls the AC line power factor and converts primary voltage to secondary low voltages for digital board.

4.3 Software/Firmware Upgrade Process A. Basic Operating (a) Standby Mode： Mode： User can just plug in power cord, then projector will enter standby mode. Power LED will show Red for around 1 sec, then show Orange continuously as the figure shown below. When the power LED shows Red, it means system is not ready for standby. In another word, if the power LED shows Orange, it means system is in standby mode and the DLP system has no power support, except MCU and its related circuits.
PAGE 49
(c) Power On： On： User can press Keypad Power to turn on projector. User can also use IR remote controller and RS-232 Command：*pow=on# to do this action. When system turning on, power LED will flash Green as the figure shown below. Power On (d) Power Off： Off： If user wants to turn off projector, user can double click keypad Power, use IR remote controller, or RS-232 Command：*pow=off#. Then, system will cool itself via fans for 3 seconds (quick cooling) or 90 seconds (normal).
