Control this projector by using a personal computer

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

• Reading warning data

• Menu setting

Note: If your PC (IBM or IBM compatible) is equipped only with a 25-pin serial port connector, a 25-pin

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.

AP – 2

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.).

6) Warning commands

Read the past warning data. The personal computer doesn’t attach the data code onto the warning commands
to send. On the other hand, the projector which has received a command attaches the warning data as the
data code to reply.

INPUT VIDEO 2 vI v2 76h 49h 76h 32h

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 1 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.

The data code of CONTRAST and BRIGHTNESS is structured by the difference data of R from G, the main data and the difference

data of B from G.

[Example 2] Set the difference data of R from G to +10, the setting main data to 0 and the difference data of

B from to -5.
