This projector can be controlled by connecting a personal computer with RS-232C terminal.
Functions can be controlled by a personal computer:
• Turn the ON or OFF
• Changing input signals
• Button input by remote control or control panel
• Menu setting

serial port adapter is required. Contact your dealer for details.
1) Interface
PROTOCOL RS-232C
BAUD RATE 9600 [bps]
DATA LENGTH 8 [bits]
PARITY BIT NONE
STOP BIT 1 [bits]
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 is structured by the address code, function code, data code and end code. The length of the
command is different by each function.
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) The command from a personal computer to the projector will be sent in 400ms.
(2) The projector will send a return command 400ms* after it has received an encode. If the command isn’t
received correctly, the projector will not send the return command.
(3) The personal computer checks the command and confirms if the command which has been sent 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 personal computer side.
• * : The sending time of return command may delay depending on the condition (during changing the
input signal, etc.).

INPUT VIDEO vI v1 76h 49h 76h 31h
When a personal computer sends the command, data code will not be attached. On the other hand, the projector
which has received a command will attach the recent operating status and then send.
[Example ] Input was Video when the operating status of the input terminal was confirmed.

8) Menu setting commands
The menu setting commands execute the menu setting of this projector. If the personal computer doesn’t send
the commands without attaching the data code, the projector which has received the command replays the
setting data as data code.
