Focus/Zoom Control Interface 

Crestron CNXFZ

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.  

Movement of the lens may occur in either position or rate mode. A jumper board 
may be selected that best accommodates the mode parameters required by the 
system. Refer to “Position/Rate Mode Definition” on page 15 for a more detailed 
explanation of position and rate mode.  

The CNXFZ, shown below, is housed in a black enclosure with a silk-screened front 
label. All electrical connections, except for the network (NET), are made to the front 
panel. Also on the front panel,  there are three LEDs and five buttons. All of these 
front panel features are discussed in subsequent paragraphs.  

At the shorter sides of the unit, the enclosure extends to form feet at a right angle to 
the side. There are three holes per foot for inserting screws to stabilize the unit.
