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

Note:

Using the computer control function of the unit, the liquid crystal projector conditions cannot be read to the computer. Therefore, confirm the conditions by transmitting the display commands for each adjustment menu and checking the conditions at the On-Screen Display. If the unit receives a command other than a menu display command, it will execute the command without displaying the On-Screen Display.
