1. Introduction
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
[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.)

1.1 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.

Sequence
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.
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).
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.
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).

4. Execution procedure of RS-232C commands via LAN
When you use a LAN function, set the STANDBY MODE to “STANDARD” or “LAN”.
You can change the certification password using the NETWORK PASSWORD in the NETWORK menu. The default password is “admin”.
You can skip the certification process by setting the NETWORK CERTIFICATION in the NETWORK menu to
OFF. When you skip the certification process, Steps 2 to 4 described below can be skipped and you can send
RS-232C commands without adding a certification data.
Example:
Sending the POWER ON command (00!) while the NETWORK CERTIFICATION is set to OFF
00!
For the procedure to set the menu, refer to the User Manual supplied with the projector.
To execute the RS-232C command via LAN while the NETWORK CERTIFICATION is set to ON, 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.
Random character string for creating the certification data that is acquired from the projector (8 characters).
Network password of the projector (1 to 32 characters).
MD5 hash calculation.
Based on the above, the execution procedures to connect to the projector and send the RS-232C commands while the NETWORK CERTIFICATION is set to ON are described below.
1. Connect to Port 63007 of the projector from the PC as a TCP/IP client.
2. After completing the connection, send the acquisition request for the certification data
(“$AK ”) from the PC to the projector.
3. Acquire “$AK******** ” on the PC as the response of the request sent in Step 2. (********: Random character string for creating the certification data)
4. Create the data for the certification on the PC.
Create the key of the certification data by linking the data acquired in Step 3 with the network character string.
For example, when the random character string is 12345678 and the password is ABCD, the key of the certification data is 12345678ABCD (character string in ASCII code).
Run MD5 hash on the key of the certification data.
Create the certification data by converting the hash-calculated 16-byte data into the ASCII code character string.
Example:
Calculation result: [4f][3c][5d][a1][7b][4f][b5][ed][2c][99][4e][bb][f6][57][67][54] (hexadecimal numeral)
Certification data: 4f 3c 5d a1 7b 4f b5 ed 2c 99 4e bb f6 57 67 54 (character string in ASCII code)
5. Send the RS-232C command with the certification data from the PC to the projector.
Example:
To send the POWER ON command (00! ) using the certification data created in Step 4:
4f3c5da17b4fb5ed2c994ebbf657675400!
6. Receive the response from the projector on the PC.
Response data has the following patterns.
Normal: 00! (Parameter is added depending on the command.)
Error in the certification data: PRV=ERRA
Command error: 00!:N

5.7 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.
