Introduction
General Descriptions

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

(DCR)
1. When RGB value of content input is smaller
than 20%, system will automatically switch to Eco mode, if
RGB value is greater than 60%, the projector will back to
Normal mode.
2. When DCR function turns on, lamp mode function is
grayed out to disable; when DCR function turns off, lamp
mode would return to setting value.
(Viewsonic agreed to take reliability and noise impact
caused by DCR function, but detailed specification of DCR
above would be finalized to suitable for reducing reliability
and noise impact by Qisda after PVT sample)

Software/Firmware Upgrade Process
1. Standby Mode
Low-Power Standby Mode：
：：
：
This mode is applied for normal situation. If you want to enter this mode, you could just plug
in power cord. Power LED will show Red for 1 sec then show Blue flashing.
When the power LED shows Red, it means system is not ready for low-power standby. In
another word, if the power LED shows Orange, it means system is in low-power standby
mode and the whole system is not supported by power except MCU and its related circuits.
Meanwhile, the power consumption should under 1W.
Full-Power Standby Mode：
：：
：
This mode is applied for Download firmware or debug.
One method to enter this mode is that you should press and hold keypad Power and Source
together, then plug in power cord. Release the two keypads until the Power LED flash blue.
