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.
