Crestron CNXFZ Focus/Zoom Control Interface CNX Focus/Zoom Control Interface: CNXFZ Description Functional Description The CNXFZ is designed to provide network control of a remotely positioned video camera site. Control is defined as the two-axis motion of the focus/zoom setting and iris control of a camera lens. Jumper Boards Four supplied jumper boards permit the support of any lens assembly requiring an input voltage in the range of +/-2.5 to +/- 12 VDC. Thus a single CNXFZ with it

Focus/Zoom Control Interface Crestron CNXFZ Presets In conjunction with the Crestron control system, the CNXFZ is capable of “memorizing” focus/zoom settings for a virtually unlimited number of presets. Each preset stores a specific setting. Positional feedback signals are essential to the implementation of presets; unless the lens supports position mode. These analog signals, provided by the lens, indicate current focus/zoom setting. Position/Rate Mode Movement of the lens may occur in

Focus/Zoom Control Interface Crestron CNXFZ NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is the +24V conductor and the GND conductor and the other twisted pair is the Y conductor and the Z conductor. NOTE: When daisy-chaining Cresnet units, strip the ends of the wires carefully to avoid nicking the conductors. Twist together the ends of the wires that share a pin on the network connector, and tin the twisted connection. Apply solder only to the ends of t

Crestron CNXFZ Focus/Zoom Control Interface Positional Feedback Signals Positional feedback signals are generated by the networked CNXFZ and input to the rest of the program. Two analog positional feedback signals, FOC_POS and ZOOM_POS, represent the current focus/zoom lens setting. The CNXFZ converts positional potentiometer wiper voltages to analog positional feedback signals. In general for example, an analog level of 0% on ZOOM_POS indicates that the lens is at its wide shot (wide and

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. Problem Solving Troubleshooting The table below provides corrective action for possible troub
