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.
