3.1. The expand command is defined one command / one line that starts "C" and ends carriage return

(0x0D).

3.2. When a projector receives carriage return (0x0D), it starts decoding.

Command.

Note) _ means a space

*Status Read Command

3.4. When it takes more than one second to receive one Command, it clears information of buffer.

(Until the projector receives the carriage return since the projector has received the first data)

3.5. A projector sends a return command in a few ms to 8000ms after the projector has received the

command.

When the computer keeps sending some commands, it must wait sending next

command until the projector has received the response. In short, make sure that the projector

sends a return command, and then the computer can send next command.

not operate properly. Command processing may not be accepted before the current command
