Important:
• Make sure that your computer and projector are turned off before connection.
• Boot up the computer fi rst, 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.
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’) fi xed.
[Function code] A code of each fi xed control move.
[Data code] A code of each fi xed control data (number) and not always indicated.
[End code] 0Dh (In ASCII code, ‘ ’) fi xed.

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 confi rms 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.
• Any commands will not be executed for 10 seconds after the power is turned on.

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 fi gures 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 reconfi rmation 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 fi gures 1 to 4 at the end.
