Channel Count / Footprint
The Channel Count, also called the DMX Footprint, is the number of consecutive DMX slots used by the selected fixture personality.
Different modes of the same fixture may have very different footprints.
For example, the MegaPointe includes personalities using:
- 7 channels
- 10 channels
- 34 channels
- 39 channels
while more complex pixel fixtures can use significantly larger footprints.
The selected personality therefore affects both:
- Which functions are available
- How much DMX space the fixture uses
TRP’s addressing and patching systems use the selected personality’s channel count when calculating fixture addresses.
