DC-DRIVE AUTO IRIS LENS SETUP

Before using a DC-drive auto iris lens, you must adjust the DC offset setting.
Use the following steps to match the camera’s DC voltage setting to the drive circuit
on the auto iris lens:
1. Remove the lens from the camera.
2. Place the front end of the camera face down on a flat surface to block all light
from the camera imager.
3. Connect the auto iris lens connector to the camera’s rear panel.
