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 configuration
The command consists of the address code, function code, data code, ACK/NAK, and end code. The length of the com-
mand varies among the functions.
[Address code] Fixed to 00. (‘30h’ ‘30h’ in the ASCII code)
[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’ ‘3Eh’ in the ASCII code. Not added to ACK.)
[End code] Fixed to .(‘0Dh’ in the ASCII code)
3. Control sequence
• 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 avail-
able. Note, however, that the response becomes slightly slower than when using the RS-232C terminals. For the use
of LAN terminals, see page 11.

Computer Projector Sequence Note
1Send the command from the personal computer
to the projector.
2
The projector will send a return command after it
receives an end code. 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).
3The personal computer checks the command and confirms if the sent command has been
received or not.
4
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.

[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 pro-
jection 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.
**** is a 4 to 8-digit password comprised of any figures 1 to 4.

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.
• 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 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 certi-
fication 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 PON 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
You can change the password using the NETWORK PASSWORD in the NETWORK menu.
The default password is “admin.”
When you use a LAN function, set the STANDBY MODE to “STANDARD.”
Refer to the operation manual of the projector for setting the STANDBY MODE.
