List of ESC/VP21 Commands

Command List

When a power ON command is sent to the projector, the power for the projector turns on. When the projector is in a command ready state, it returns the "3Ah"

(:)code. Furthermore, when command processing is complete, the projector also returns a ":" code.

The ":" code status can be used to determine whether the projector is ready or busy. If command processing terminates with an error, an error message is output and then the ":" code is sent.
