CAMERA LAYOUT
INSTALLATION
Lens Mounting
The CC3500 and CC3600 Series cameras can use fixed iris, manual iris, auto iris, or direct drive
lenses. Cameras are factory-set for CS-mount lenses, but easily adjusted for C-mount lenses.
1. C-Mount Lens Only - Loosen the two back focus locking screws. Rotate the back focus
adjustment ring fully counterclockwise before installing the C-mount lens (refer to the section on
Back
Focus Adjustment
).
2. Remove the cosmetic trim ring from the back of the camera (refer to Figure 1). Set the lens mode
selector switch on the side of the camera to AI (auto iris video drive lens) or DD (auto iris DC
drive lens). Refer to the Switch Settings section. Switch setting is determined by the type of lens
used.
3. Screw the lens onto the lens mount. Be careful to prevent dust from entering the space between the
lens and the CCD element. If necessary, use clean, compressed air to remove any foreign matter.
4. Thread the lens cable through the cosmetic trim ring.
5. Connect the direct drive (DD) or auto iris (AI) lens to the 4-pin iris drive connector located on the
side of the camera. Pin connections for the iris drive connector are as follows.
