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 retirn command.
(3) The personal computer checks the command and confirms that 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, playing back the PC card, etc.).
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.

6) Warning commands
Read the past warning data. The personal computer doesn’t attache the data code onto the warning commands to
send. On the other hand, the projector which has received a command, attach the warning data as the data code
to reply.
[Example 1]
The fan was down when the power was ON and the past data of the warning was confirmed.

8) Picture adjustment commands
The picture adjustment commands execute the picture adjustment 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.
How to set the grade
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. Use ASCII letters code to set the grade for setting data. Please refer to the table below for HEX code.
ASCII HEX
CONTRAST P 50h
BRIGHTNESS Q 51h
SHARPNESS R 52h
TINT S 53h
COLOR T 54h
ASCII '+' '–' '0' '1' '2' '3' '4' '5' '6' '7' '8' '9'
HEX 2Bh 2Dh 30h 31h 32h 33h 34h 35h 36h 37h 38h 39h
[Example 2] The TINT was set to +10 when the setting status was confirmed.
[Example 1] 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.

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 then send.
[Example ] Input was Video when the operating status of the input terminal was confirmed.
