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.)
• RS232C cables may be necessary when you control the projector. Contact your dealer for details.
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.

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 cor-
rectly, 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.

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. (LAMP OPERATING
TIME: “h” and “m” represent hour and minute respectively. )
