Enclosure Preparation

The camera and lens are packed separately to the DFNEXT enclosure.

The lens is shipped with a rubber gasket and a brass flange attached to the aluminium flange that holds the lens. The rubber gasket and brass flanges are attached to the lens through 5x M4 bolts.

To attach the lens to the enclosure, first detach the power cables feeding power to the Hard Drives. Then, lift each hard drive individually and carefully detach the SATA cables connected to the Hard Drive. Feed the SATA and power cables to the side of the enclosure opposite to the lenses. This gets them out of the way of the lens and camera that will be installed shortly.

Install Procedure

Feed the LC shutter cable through the lens opening in the enclosure and through the brass ring. Insert the lens and align bolts with bolt slots on the enclosure ensuring that the LC shutter points towards the computer and the white line points straight up.

Place brass ring on the inside of the box and roughly align it with the bolts.

The following step requires the camera and lens cap to be removed. Insert the camera in the enclosure being careful not to damage the LC shutter exposed at the base of the lens.

To attach the lens to the camera body, align the lens and the camera. Twist the lens clockwise about 40 degrees, aligning the line on the lens with the dot on the camera body.

Bring the lens and camera body together and, holding the lens by the flange, twist the lens anti clockwise. When the alignment mark on the lens points up again, a significant clicking noise should be observed and the lens and camera are now attached.

Once the lens is attached to the camera body, align the brass ring with one of the bolts and tighten the bolt until it just grips the brass ring. you might need to clamp the brass ring and camera lens with your hand to ensure the bolts grip to the brass ring.
