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:

• Connect the computer with the projector on a one-to-one basis.

• 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 Com port may not function.)

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

2. Control command diagram

Computer Projecto

The command consists of the address code, function code, data code, and end code. The length of the command varies among the functions.

Address code Function code Data code End code ASCII ‘30h’ 30h’ Function Data ‘0Dh’ Character 00 Function Data

[Address code] 00 (In ASCII code, ‘30h’ ‘30h’) ﬁxed. [Function code] A code of each ﬁxed control move. [Data code] A code of each ﬁxed control data (number) and not always indicated. [End code] (In ASCII code, ‘0Dh’) ﬁxed.

3. Control sequence

Sequence Note

Send the command from the

personal computer to the projector. The projector will send a return

command after it receives an end code.

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. 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.

[Example] When turning the power ON. (Figures and symbols enclosed in quotation marks are ASCII codes.):

[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

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. 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.
