Send the command from the
1
personal computer to the projector.
The projector will send a return
command after it receives an end
code.
2
The personal computer checks the
command and confirms if the sent
3
command has been received or not.
Use the check command to see
if the projector has executed the
4
command.
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.
Although the projector receives the commands, it
in some cases does not execute the commands.
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.
• Although the projector sends out the return command, the command may not take effect in the following
cases.
(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
• 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.

[Method of checking state of projector]
START
Check the following.
• 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.
• The projector is in the state of being unable to send out
a command.
→ Use command “00vST” to check if the projector
operates normally.
Note: In the following conditions, the projector
does not respond even if it operates
normally.
• Immediately after turning on the power
(for about 20 seconds to 2 minutes)
• During switching signals (about 10
seconds)
• In the process of the auto position
(about 10 seconds)
• During locking the password

The PC sends the command without attaching the data code to 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.

on the menu setting are applied. Refer to “Menu operation” in the User Manual for more details.
How to set the value
Use the character or ASCII code as shown below to set the value.
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 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 figures 1 to 4 at the end.
