Controlling the projector using a personal computer

This projector can be controlled by connecting a personal computer with RS-232C terminal.

In addition, by connecting multiple projectors to each other in a daisy chain conﬁguration, you can control each

projector from one personal computer.

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

[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. ID code

cannot be designated at command sending.)

(For the recommended procedure to use the former command systems, see “Controlling the projector using a

personal computer” for FL7000U.)

Connection

Important:

• 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.)

• To use a daisy chain conguration, make sure to use Mitsubishi projectors supporting RS-232C communication. If

the projectors or other devices made by other manufacturers are connected, operation is not guaranteed.

2. Control command configuration The command consists of the address code, ID code, function code, data code, ACK/NAK, and end code. The length of the command varies among the functions. Address code ‘30h’ ‘30h’ 00 ASCII code Character ID code ‘30Bh’ ID ‘30Bh’ ;ID; Function code Function Function Data code Data Data ACK/NAK ‘3Ah’ ‘4Eh’ :N End code ‘0Dh’ [Address code] Fixed to 00.

• 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. For the use of LAN terminals, see page 17.

[RS-232C control flowchart] START Sending out command No NAK returned No response for 1 second or longer Awaiting response from projector NAK returned Command is sent successfully. Command is executed successfully. Checking execution of command (sending out check command) Command is sent successfully. Command execution fails. Check the following. • The ID code is out of the valid range. • Check that the function code is correct. • Check that the data code is correct.

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.

4.4 Direct commands (Not executable in stand-by mode. Possible only to read during BLANK.) The direct commands are used to numerically adjust the geometrical correction and bright uniformity correction. When the computer sends the command without adding the setting value, the projector returns the received command with the current setting value added as a data code.

4.6 Menu setting commands (Not executable in stand-by mode. Possible only to read during BLANK.) The menu setting commands are used for the menu setting of this projector. If the personal computer sends the command without attaching the data code, the projector attaches to the received command its current setting value as the data code and send it back to the PC.

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.

5. Execution procedure of RS-232C commands via LAN When the RS-232C command is executed via LAN, a 32-byte connection certification data must be added before the RS-232C command. To create a 32-byte certification data, following information and procedure are required.
