70 List of ESC/VP21 Commands
Command List
When a power on command is sent to the projector, the power will turn on
and the projector will change to warm-up mode. When the power has
turned on, a colon ":" (3Ah) will be returned.
When the projector executes a command, it returns a ":" and waits for the
next command to be sent.
If command processing terminates with an error, the projector outputs an
error message and then returns the ":" code.
* When issuing any of the above commands, tack a Carriage Return (CR)
code (0Dh) on to the end.
