Info

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

•In the case of transmitting commands during standby, it takes a maximum of 30 seconds until the response code is received.

•When the power is turned on during standby with the “POWER ON” command, wait for at least 30 seconds after the power has been turned on, and then transmit the next command.

Note

•When using the computer control function of the projector, the projector’s operating status cannot be read by 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 command without displaying the on-screen display.

Commands

Example:

•When “BRIGHT” of INPUT 1 image adjustment is set to –10.
