Focus/Zoom Control Interface 
Crestron CNXFZ
 
Most lens types operate in rate mode. If position feedback is provided then 
focus/zoom presets can be recalled. Without feedback, lens presets cannot be 
achieved in rate mode. Some lenses can switch between rate and position mode; the 
CNXFZ provides the appropriate connections to facilitate this. This type of lens can 
achieve presets without feedback.
