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.
