A. Thread the video-type auto-iris lens on to the lens mount.
B. Connect the lens control wiring to the three position terminal block
on the back of the camera. The following diagram illustrates the pin
connections. Red, white and black are the most common colors
used for wiring on video-type auto iris lens.

D. Apply power to the camera.
E. Adjust the focus ring on the lens for an optimum picture. If a picture
is not visible, set the lens for proper exposure by adjusting the ALC
(automatic level control) and Level on the lens. The ALC setting
can range between AVG (average) or PK (peak). A mid-range
setting is appropriate for most applications.

To slow the reaction of the lens to changing light, set the
range to the AVG setting to average the video level from
the camera. Use when there are bright spots in the
picture such as lights or glare from the sun.
To increase the speed of the lens reaction to the changing
light, set the lens adjustment to PK so the lens will adjust
to the brightest or peak object in the video. Use this
setting if you want to see the brightest object and not the
background objects.
Adjust the Level control for the best picture during the day. A
night adjustment may not provide the proper setting for
controlling the light during the day.
Set the back focus of the camera before the final adjustment
of the video level.
If the lens oscillates between open and closed under bright
lights, slowly turn the gain adjustment counter clockwise until
the oscillating stops.
Increase the light getting to the camera by adjusting the level
control and re-adjusting the gain control as necessary.
