Auto iris video-type connection
Prosilica GX cameras provide built-in auto iris controls for controlling video-type
auto-iris lenses. These lenses are available from many popular security lens
companies including Pentax, Fujinon, Tamron, Schneider and others.
Remote iris lens control allows the camera to be more adaptable to changing light
conditions. It allows the user to manually control the exposure and gain values and
rely solely on the auto iris for adjustment to ambient lighting.
Hirose connector
This cable side Hirose connector is available to purchase from Allied Vision. Order
code 02-7004A.
Voltage specification
The following diagram uses CAMERA POWER to power the video iris lens, and
assumes CAMERA POWER = 12 V. Most video iris lenses operate at a 8 to 16 V input
voltage. Therefore, this circuit is not appropriate if using a 24 V camera power
supply. Doing so may irreparably damage your lens. Please consult your video iris
lens specifications for the appropriate drive voltage.
