This connector provides the signals necessary to control the iris, focus, and zoom of
most commercially available TV Zoom lenses. The camera can be configured to
operate lenses with unipolar voltage requirements of 6V up to 12V or lenses which
operate with bipolar voltages from
± 6V up to ± 12V. This voltage level can be controlled
through software. The default voltage will be set to 6V. The current capacity for each
axis is 50mA.
CARE MUST BE TAKEN NOT TO EXCEED THE LENS MANUFACTURERS
VOLTAGE SPECIFICATION.
This connector also provides the signals necessary to operate a video auto iris type of
lens.
The lens control connector is a Hirose 3260-8S3. The mating cable connector is Hirose
3240-8P-C(50). This connector can be purchased from AVT Canada Inc. or from
