Lens control port
The lens control connector is a Hirose 3260-8S3. This connector provides the
signals necessary to control the iris, focus, and zoom of most commercially
available TV Zoom and Video-type auto-iris lenses. The cable side connector is
Hirose 3240-8P. The camera can be configured to operate lenses with unipolar
voltage requirements of 6 to 12 V or lenses that operate with bipolar voltages from
±6 V up to ±12 V. This voltage level can be controlled through software. The default
voltage is set to 6 V. The current capacity for each axis is 50 mA.
