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 rst, 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 conguration, 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.

• Example of ID setting (When Group A, which performs multi-projection with two projectors, and Group B, which
performs multi-projection with three projectors, are connected.)
Projector 1
PROJECTOR ID : 01
GROUP ID : A
Multi-projection Group A
Projector 2
PROJECTOR ID : 02
GROUP ID : A
Projector 3
PROJECTOR ID : 03
GROUP ID : B
Multi-projection Group B
Projector 4
PROJECTOR ID : 04
GROUP ID : B
Projector 5
PROJECTOR ID : 05
GROUP ID : B
You can assign the ID code to the control command.
• When the command having the PROJECTOR ID is sent, only the projector having the corresponding ID returns the
response.
(When the PROJECTOR ID is set to ALL on the projector, the projector responds to all the PROJECTOR ID
numbers assigned to the commands.)
• When the command having the GROUP ID is sent, all the projectors having the corresponding ID return the
response.
• When the command having no ID code is sent, all the projectors return response.
When the projectors are connected in a daisy chain conguration, you are recommended to set the PROJECTOR ID
to other than “ALL” and assign the PROJECTOR ID differently for each projector to communicate with each projector
individually. Refer to the operation manual of the projector for setting the PROJECTOR ID.
When you use a daisy chain conguration, set the STANDBY MODE to “STANDARD.” Refer to the operation manual
of the projector for setting the STANDBY MODE.
Important:
• Adapters may be necessary depending on the PC connected to this projector. Contact your dealer for details.

2. Control command configuration
The command consists of the address code, ID code, function code, data code, ACK/NAK, and end code. The length
of the command varies among the functions.
Address code ID code Function code Data code ACK/NAK End code
ASCII code ‘30h’ ‘30h’ ‘30Bh’ ID ‘30Bh’ Function Data ‘3Ah’ ‘4Eh’ ‘0Dh’
Character 00 ;ID; Function Data :N
[Address code] Fixed to 00. (‘30h’ ‘30h’ in the ASCII code)
[ID code] Code specifying the projector to be controlled (For ID, specify either the PROJETOR ID (00 to
63) or GROUP ID (0A to 0Z). When the code is not specied, all the connected projectors are
controlled.)
[Function code] Code unique to each control operation.
[Data code] Data (value) unique to each control operation (Not always indicated.)
[ACK/NAK] Code indicating the NAK return as described below
Fixed to :N (‘3Ah’ ‘3Eh’ in the ASCII code. Not added to ACK.)
[End code] Fixed to . (‘0Dh’ in the ASCII cade)
3. Control sequence

Sequence Note
1Send the command from the
personal computer to the projector.
2
The command input from the
SERIAL IN terminal is sent to the
projector connected to the SERIAL
OUT terminal.
3
After receiving the end code, the
projector sends the return command
to the device connected to the
SERIAL IN terminal.
If the projector does not receive commands
normally, that is, if the projector is not connected
physically or unable to receive commands, it does
not send out a return command.
In addition, when the ID code of the command is not
corresponded to that of the projector, the projector
doesn’t send a return command.
The projector sends out a return command within
one second at the latest.
When the received command cannot be executed,
NAK is returned (as described below).
4
The return command input from the
SERIAL OUT terminal is sent to the
device connected to the SERIAL IN
terminal.
The personal computer receives the commands as
many as the number of the projectors that send the
returned commands. However, the receiving order
of the returned commands may vary depending
on the projector status.
5
The personal computer checks the
command and confirms if the sent
command has been received or not.
6
Use the check command to see
if the projector has executed the
command.
This projector sends various codes other than the
return code. When having a control sequence by
RS-232C, reject other codes from the personal
computer.
• NAK return
In the following cases, the projector returns the command with “:N” added.
(1) Though the command sent from the computer is received by the projector successfully, it cannot be
executed because the projector is in the operation prohibition state.
(2) The data length of the sent command is incorrect or the command is invalid.
(3) The ID assigned to the command is out of the valid range (other than 00 to 63 or 0A to 0Z).
(4) The signal length of the command is 48 bytes or longer.
• When a command is sent out during the following operations, it may not be executed.
(1) During signal switching
(2) In the process of the auto position
(3) After the power is turned on.
After the power is turned on, no command is received until the image is displayed. (Usually, it takes about
20 seconds. However, when the lamp illumination takes time, more time will be required accordingly.) In
this case, the projector returns the received command with NAK added.
• The return command is sent out within 1 second at the latest.
• When sending commands successively, wait to receive the return command of the current command before
sending a next command.

4
• The projector may not receive a command when the splash screen is being displayed immediately after
turning on the power. Use command “00r10” to cancel the splash screen.
• While using the LAN terminals, the LAN functions take precedence.
• For the LAN terminals, the same commands as those for connecting with the TCP/IP (port number 63007) are
available. Note, however, that the response becomes slightly slower than when using the RS-232C terminals.
For the use of LAN terminals, see page 17.

4.4 Direct commands (Not executable in stand-by mode. Possible only to read during BLANK.)
The direct commands are used to numerically adjust the geometrical correction and bright uniformity correction.
When the computer sends the command without adding the setting value, the projector returns the received
command with the current setting value added as a data code.
