Correct command formatting
Add a space between the code and the number when entering commands.
For example, PXT50 can be entered as PXT 50. To increase or decrease a value in some commands,
enter n for the next value and p for the previous value. For example:
(OVS0): OFF
(OVS1): ZOOM
(OVS2): CROP
If the current over scan (OVS) setting is off (OVS n), the command OVS p sets the value to zoom.
Understanding message format
Commands sent to and from GS Series 599 are formatted as simple text messages consisting of a
three letter command code, an optional four letter subcode, and optional data.
