DLP™ Projector

XD3500U

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

RS-232C cable

SERIAL

To RS-232C terminal

D-SUB 9-pin D-SUB 9-pin

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.

This projector uses RXD, TXD and GND lines for RS-232C control.

For RS-232C cable, the supplied cable (crossover cable) should be used.

2. Control command configuration

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

Sequence

Send the command from the personal computer to the projector.

The projector will send a return command after it receives an end code.

Note

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.

When the received command cannot be executed,

NAK is returned (as described below).

4

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.

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.

• 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.

The projector receives no commands for about 20 seconds (or for 2 minutes at the longest if the lamp does not light up promptly as the life is expiring). 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.

Check the following.

• Check that the function code is correct.

• Check that the data code is correct.

• Check that the projector is able to issue the return command.

→ Check the projector s operation using the 00vST command.

Note: In the following cases, NAK is returned even when the projector is in normal condition.

• Immediately after the power is turned on (about 20 seconds to 2 minutes)

• During input switching

• During auto positioning

• During password lock

Check the following.

• Check that the command begins with “00”.

• 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.

[Method of checking state of projector]

Sending “00vST”

To normal operation

0–3

Enter password.

Send out “00PASS****.”

Projector error

Send out “00vER” to check error details.

Recover from error state.

5

Projector is functioning.

Use “00FNCOFF” to cancel the current function.

[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 the recommended procedure to use the former command systems, see “Controlling the projector using a personal computer” for FL7000U.)

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.
