Controling 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

Important:
• 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 Comport may not function.)
• Adapters may be necessary depending on the PC connected to this projector. Contact your dealer for details.
1) Interface
PROTOCOL RS-232C
BAUD RATE 9600 [bps]
DATA LENGTH 8 [bits]
PARITY BIT NONE
STOP BIT 1 [bit]
FLOW CONTROL NONE
This projector uses RXD, TXD and GND lines for RS-232C control.
For RS-232C cable,the reverse type cable should be used.
2) Control command diagram
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
HEX 30h 30h Function Data 0Dh
ASCII '0' '0' Function Data
[Address code] 30h 30h (In ASCII code, '0' '0') 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] 0Dh (In ASCII code, ' ') fixed.

3) Control sequence
(1) Send 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 command is not received
correctly, the projector will not send the return command.
(3) The personal computer checks the command and confirms if the sent command has been executed or not.
(4) 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.
• During signal switching, the command may not take effect even when the projector sends the return
command. After signal switching completes, wait for the mode indication to disappear before sending the
next command.
• When sending commands successively, wait to receive the return command of the current command before
sending a next command.
• Keep intervals of at least 400 ms between receipt of a return command and sending of a next command.
[Example] When turning the power ON (Figures and symbols enclosed in quotation marks are ASCII codes.):

• Any commands will not be executed for 10 seconds after the power is turned on.
4) Operation commands (Not executable in stand-by mode. When the commands for input select are sent
while the splash screen is being displayed, the splash screen is only canceled.)
The operation commands are used for the basic operation setting of this projector. They may not be executed
while the signals are changed. The operation commands have no data codes.

8) Password lock commands
The password lock commands control the password lock. The password lock enabling or disabling command is
sent with a 4-digit figure (password) 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.

Data (Receive)
The PC sends the command without attaching the data code to it. On the other hand, the projector attaches
to the received command it’s current operating status as the data code and send it back to the PC.

The menu setting commands are used for the menu setting of this projector. If the personal computer sends the
command without attaching the data code, the projector attaches to the received command it’s current setting
value as the data code and send it back to the PC.
