3. Basic format

Commands from the computer are sent in the following order: command, parameter, and return code. After the
unit processes the command from the computer, it sends a response code to the computer.
Command format
C1 C2 C3 C4 P1 P2 P3 P4
Response code format
Normal response
O
Problem response (communication error or incorrect command)
E
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.
