1. Introduction
The Boxlight PRO80S3 Projector is a three-chip DLP projector with a native resolution of 1280x720 pixels (16:9 aspect
ratio). The projector accepts 720p video through a DVI-D connector on the rear panel.
1.1
Controllers
The projector is controlled by a pair of MTV312M64 microcomputers. The first is the main controller and is responsible for
lamp ballast and formatter initialization. It continuously monitors the state of the formatters, the ballast and the video input
primarily to prevent the lamp from extinguishing due to loss of video or unintentional resetting of the formatters due to
power fluctuations. Communication with the controller is through an RS-232 interface using a simple command/parameter
protocol. The second processor manages the IR remote control functions: lens shift, focus and zoom. It has no external
communications interface except the IR receiver.
