1. Introduction

This projector can be controlled by connecting a personal computer with RS-232C terminal.

In addition, by connecting multiple projectors to each other in a daisy chain configuration, you can control each projector from one personal computer.

PC-controllable functions:

Turning the power ON or OFF

Changing input signals

Inputting commands by pressing the buttons on the control panel and remote control

Menu setting

[Compatibility with the former models]

To use the RS-232C commands designed for the former models of Mitsubishi projector, by inputting “00COMMAND0”, the projector responds in the same way as the former models. (No NAK is returned. For NAK response, see page 4. ID code cannot be designated at command sending.)

(For the recommended procedure to use the former command systems, see “Controlling the projector using a personal computer” for FL7000U.)
