Some commands have ranges, while others are absolute. If a number greater than the maximum range is received, it is
automatically set to the maximum number for that function. If a command is received that is not understood, a "?" is
returned. With absolute settings, "0" is off, 1-9999 is on. The one exception is the Power command, where 0 is off and 1 is
on.

Limitations
The CLI cannot respond to commands coming in at a high-rate. Therefore, a delay must occur between commands to
ensure that the command gets properly executed. To assure the projector can process a command, wait 3 seconds
before entering the next command.
