XL8U / SL4U

Controling 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 to SERIAL terminal

RS-232C cable to SERIAL port

D-SUB 9P 8P

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 LCD projector.

(If you do not follow this instruction, the Comport may not function.)

• There are two RS-232C terminals on the projector. You can use either of them.

• 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.

[Data code] A code of each fixed control data (number) and not always indicated.

[End code] 0Dh (In ASCII code, ' ') fixed.

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.

4) Operation commands

(Not executable in stand-by mode. When the commands for input select are sent while the splash screen is being displayed, the splash screen is only canceled.)

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.

9) Password lock commands

The password lock commands control the password lock. The password lock enabling or disabling command is sent with a 4-digit figure (password) 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-digit figure (password) at the end.
