Info
• If you are controlling the projector from a computer using RS-232C commands, wait at least 30 seconds
after turning the projector on before sending any commands.
• When more than one code is being sent, send each command only after the response code for the previ-
ous command from the projector is verifi ed.
• When using the computer control function of the projector, the projector's operating status cannot be read
by the computer. There fore, confi rm 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.
