Message Format; Message Types And Formats - Christie GS Series Technical Reference

Message format

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.

Message types and formats

Commands sent to and from the projector are formatted as simple text messages consisting of a three
letter command code, an optional four letter subcode, and optional data.
You can include optional features such as message acknowledgments with your commands.
