You can control the projector from an external device using ESC/VP21.
When the power ON command is transmitted to the projector, the power turns on and enters warm-up mode. When the projector's power has turned on, a colon ":" (3Ah) is returned.
When a command is input, the projector executes the command and returns a":", and then accepts the next command.
If the command being processed terminates abnormally, an error message is output and a ":" is returned.
You can also execute some of the ESC/VP21 commands by Web API.
