A computer can be used to control the projector by connecting an RS-232C cable (null modem, cross type,
commercially available) to the projector. (See page 14 for connection.)

Set the serial port settings of the computer to match those of the table on the next page.

Commands from the computer are sent in the following order: command, parameter, and return code. After the
projector processes the command from the computer, it sends a response code to the computer.

When more than one code is being sent, send each command only after the OK response code for the previous
command from the projector is verified.

• When using the computer control function of the projector, the projector operating status cannot be read to the computer.

Therefore, confirm the status by transmitting the display commands for each adjustment menu and checking the status with
the On-screen Display.
