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:
• 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 Comport may not function.)
• Adapters may be necessary depending on the PC connected to this projector. Contact your dealer for details.

This projector uses RXD, TXD and GND lines for RS-232C control.
For RS-232C cable, the reverse type cable should be used.
2) Control command diagram
The command consists of the address code, function code, data code, and end code. The length of the command
varies among the functions.

3) Control sequence
(1) Send 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 command is not received correctly, the projector will not send the return command.
(3) The personal computer checks the command and confirms if the sent command has been executed or not.
(4) 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.
• During signal switching, the command may not take effect even when the projector sends the return command.
After signal switching completes, wait for the mode indication to disappear before sending the next command.
• When sending commands successively, wait to receive the return command of the current command before
sending a next command.
• Keep intervals of at least 400 ms between receipt of a return command and sending of a next command.
• Any commands will not be executed for 10 seconds after the power is turned on.

9) 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 projection
of image when password lock has been set to DISPLAY INPUT. The password input command is sent with a 4 to 8digit password comprised of any figures 1 to 4 at the end.
