AUTO-IRIS
LENS INSTALLATION
AND ADJUSTMENT
The KC4500MN and KC6500MN cameras support dc
auto-iris lenses. Perform the following steps to install and
adjust a dc-type auto-iris lens.
1.
Thread the dc iris lens onto the lens mount on the
front of the camera.
2.
If using an Ultrak lens, skip to step three.
If using a non-Ultrak lens, use the manufacturer’s
instructions to solder the connector that comes
supplied with the camera to the lens control wires.
The pin-out and wire color-coding for DC-type auto-
iris lenses can vary from one manufacturer to
another.
3.
Plug the connector into the dc iris jack on the side of
the camera. The connector is keyed and can only be
inserted into the jack one way.
