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. For NAK response, see page 4. 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.)

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.

To connect with one projector:

To connect with multiple projectors (in a daisy chain conﬁguration):

• Example of ID setting (When Group A, which performs multi-projection with two projectors, and Group B, which

Projector 1 PROJECTOR ID : 01 GROUP ID : A

Multi-projection Group A

Projector 2 PROJECTOR ID : 02 GROUP ID : A

Projector 3 PROJECTOR ID : 03 GROUP ID : B

Multi-projection Group B

Projector 4 PROJECTOR ID : 04 GROUP ID : B

Projector 5 PROJECTOR ID : 05 GROUP ID : B

performs multi-projection with three projectors, are connected.)

You can assign the ID code to the control command.

• When the command having the PROJECTOR ID is sent, only the projector having the corresponding ID returns the

response.

(When the PROJECTOR ID is set to ALL on the projector, the projector responds to all the PROJECTOR ID

numbers assigned to the commands.)

• When the command having the GROUP ID is sent, all the projectors having the corresponding ID return the

response.

• When the command having no ID code is sent, all the projectors return response.

When the projectors are connected in a daisy chain conguration, you are recommended to set the PROJECTOR ID to other than “ALL” and assign the PROJECTOR ID differently for each projector to communicate with each projector individually. Refer to the operation manual of the projector for setting the PROJECTOR ID.

When you use a daisy chain conﬁguration, set the STANDBY MODE to “STANDARD.” Refer to the operation manual of the projector for setting the STANDBY MODE.

Important:

• Adapters may be necessary depending on the PC connected to this projector. Contact your dealer for details.

2. Control command conﬁguration

Computer

Projector 1

Projector 2

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 ID code Function code Data code ACK/NAK End code ASCII code ‘30h’ ‘30h’ ‘3Bh’ ID ‘3Bh’ Function Data ‘3Ah’ ‘4Eh’ ‘0Dh’ Character 00 ;ID; Function Data :N

[Address code] Fixed to 00. (‘30h’ ‘30h’ in the ASCII code)

[ID code] Code specifying the projector to be controlled (For ID, specify either the PROJETOR ID (00 to

63) or GROUP ID (0A to 0Z). When the code is not speciﬁed, all the connected projectors are

controlled.) [Function code] Code unique to each control operation. [Data code] Data (value) unique to each control operation (Not always indicated.) [ACK/NAK] Code indicating the NAK return as described below Fixed to :N (‘3Ah’ ‘4Eh’ in the ASCII code. Not added to ACK.) [End code] Fixed to . (‘0Dh’ in the ASCII cade)

3. Control sequence

[Example] When the personal computer and two projectors are daisy-chained:

Sequence Note

Send the command from the

personal computer to the projector. The command input from the

SERIAL IN terminal is sent to the

projector connected to the SERIAL OUT terminal.

After receiving the end code, the projector sends the return command to the device connected to the SERIAL IN terminal.

The return command input from the SERIAL OUT terminal is sent to the

device connected to the SERIAL IN terminal.

The personal computer checks the

command and conﬁrms if the sent command has been received or not.

Use the check command to see if the projector has executed the

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. In addition, when the ID code of the command is not corresponded to that of the projector, the projector doesn’t send 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).

The personal computer receives the commands as many as the number of the projectors that send the returned commands. However, the receiving order

of the returned commands may vary depending on the projector status.

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. (3) The ID assigned to the command is out of the valid range (other than 00 to 63 or 0A to 0Z). (4) The signal length of the command is 48 bytes or longer.

• 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. After the power is turned on, no command is received until the image is displayed. (Usually, it takes about

20 seconds. However, when the lamp illumination takes time, more time will be required accordingly.) 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.

For the use of LAN terminals, refer to “4. Execution procedure of RS-232C commands via LAN”.

• When the NAK isn’t returned, check the RS-232C command system (00COMMAND).
