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

To RS-232C
terminal
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 rst, 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.

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).
3
The personal computer checks the
command and conrms 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.
• 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
available. Note, however, that the response becomes slightly slower than when using the RS-232C terminals.

START
Check the following.
•Check that the function code is
correct.
•Check that the data code is correct.
•Check that the projector is able to
issue the return command.
→Check the projectorʼs operation
using the 00vST command.
Note: In the following cases, NAK is
returned even when the
projector is in normal condition.
•
Immediately after the power is turned
on (about 20 seconds to 2 minutes)
•During input switching
•During auto positioning
•During password lock
Check the following.
•Check that the command begins
with “00”.
•The projector is not supplied with
AC power.
→Check that AC power cord is
connected.
→Turn on the power. (Turn on the
circuit breaker or main switch.)
•Not connected with the projector.
→Check that the RS-232C cable is
connected.
→Check the RS-232C cable for
electrical discontinuity.
[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.)

4.7 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 gures 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 com-
mand with “0” at the end. There is no reconrmation of the password. The password input command is for en-
abling projection 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 gures 1 to 4 at the end.
