Crestron CNXFZ 

Focus/Zoom Control Interface

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.  

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 its 
four jumpers can control nearly any lens in the industry. Refer to the table below for 
exact voltage outputs for each jumper board.  

NOTE:  If no jumper board is connected to the CNXFZ, the lens outputs are 
disconnected.
