Commands from the computer are sent in the following order: command, parameter, and return code.After the projector processes the command from the computer, it sends a response code to the computer.•When controlling the projector using RS-232C commands from a computer, wait for at least 30seconds after the power has been turned on, and then transmit the commands.•When more than one code is being sent, send each command only after the response code for theprevious command from the projector is verified.
