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. If the projector receives a command other than a menu display command, it will execute the com-
mand without displaying the On-screen Display.
