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 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.

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 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.
Physical Description
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.

CNXFZ Ports
A number of ports bearing silk-screened labels are located on the CNXFZ. Refer to
the illustration and descriptions after this paragraph.

CNXFZ
NET
This 6-pin, 6-position RJ11 modular jack is used to connect the CNXFZ to the
control system.
NOTE: Review the latest revision of the Network Modular Cable Requirements
(Doc. 5682). Most 4-conductor phone cables are wired in a crisscross fashion and are
not compatible with Crestron equipment.
LENS
This DB15 female connector provides three channels for zoom, focus, and iris, as
well as additional signals depending on lens. Refer to the pinout table on the next
page. A 15-pin D-sub male connector with hood (P/N 748048-1) is supplied and
attaches to the LENS port. To properly wire this male connector, a wiring schematic
for each lens type (A through D) follows the pinout table. Crestron maintains a
limited number of cabling drawings for lenses. Refer to “Appendix: Application
Examples” on page 18 for specific lens applications. The information in the appendix
offers recommended cabling connections with the appropriate lens type.
