DLP™ Projector
UD8400U/UD8400LU/UD8350U/UD8350LU
Controlling the projector using a personal computer
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. 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.)

Connection
Important:
• Make sure that your computer and projector are turned off before connection.
• Boot up the computer first, and then plug the power cord of the projector.
(If you do not follow this instruction, the Com port may not function.)
• To use a daisy chain configuration, make sure to use Mitsubishi projectors supporting RS-232C communication. If
the projectors or other devices made by other manufacturers are connected, operation is not guaranteed.
To connect with one projector:
