Controlling the projector using a personal computer
This projector can be controlled by connecting a personal computer with RS-232C terminal.
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
Connection
Important:
• Connect the computer with the projector on a one-to-one basis.
• 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.)
• 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, function code, data code, ACK/NAK, and end code. The length of the com-
mand varies among the functions.
[Address code] Fixed to 00. (‘30h’ ‘30h’ in the ASCII code)
[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 code)
3. Control sequence
• 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.
• 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.
The projector receives no commands for about 20 seconds (or for 2 minutes at the longest if the lamp does not
light up promptly as the life is expiring). 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.
• 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 avail-
able. Note, however, that the response becomes slightly slower than when using the RS-232C terminals. For the use
of LAN terminals, see page 11.

Computer Projector Sequence Note
1Send the command from the personal computer
to the projector.
2
The projector will send a return command after it
receives an end code. 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.
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).
3The personal computer checks the command and confirms if the sent command has been
received or not.
4
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.

[RS-232C control flowchart]
[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 the recommended procedure to use the former command systems, see “Controlling the projector using a personal
computer” for FL7000U.)

4. Command list
4.1 Operation commands
The operation commands are used for the basic operation setting of this projector. They may not be executed
while the signals are changed. The operation commands have no data codes. (When the commands for input
select are sent while the splash screen is being displayed,the splash screen is only canceled.)
[Example] When setting the input signal to COMPUTER 1. (Values enclosed in quotation marks are ASCII
codes.):
4.2 Reading command diagram
The projectors operating status, such as POWER-ON/OFF and the currently selected input terminal, etc. can be
monitored.
Use the following commands to obtain the values of the items in the INFORMATION menu.
“hhhh” and “mm” represent hours and minutes respectively.
“HHHH” and “VVVV” represent the horizontal and vertical resolutions respectively.
“***.**” represents the vertical frequency(in Hz) or the horizontal frequency (in kHz).

Use the following commands to obtain other information.
The PC sends the command without attaching the data codeto it. On the other hand, the projector attaches to
the received command its current operating status as the data code and send it back to the PC.
[Example] When checking the currently selected input terminal (when the INPUT VIDEO is being selected).

4.4 Direct commands (Not executable in stand-by mode. Possible only to read during muting.)
The direct commands are used to numerically adjust the volume and keystone.
When the computer sends the command without adding the setting value, the projector returns the received com-
mand with the current setting value added as a data code.
How to set the value
Use the character or ASCII code as shown below to set the value.
[Example] When setting the volume to 15. (Values enclosed in quotation marks are ASCII codes.):
4.5 Function commands (Not executable in stand-by mode. When the mute commands are sent while the splash

4.7 Password lock commands
The password lock commands control the password lock. The password lock enabling or disabling command is
sent with a 4 to 8-digit password comprised of any figures 1 to 4 added to the end of the data code. When the
password lock is enabled or disabled successfully, the projector sends a return command comprising the data
code, password, and “1” at the end. When enabling or disabling the password lock fails, it sends a return command
with “0” at the end. There is no reconfirmation of the password. The password input command is for enabling pro-
jection of image when password lock has been set to DISPLAY INPUT. The password input command is sent with
a 4 to 8-digit password comprised of any figures 1 to 4 at the end.
**** is a 4 to 8-digit password comprised of any figures 1 to 4.
