Installation
LENS MOUNTING
The camera can use a fixed iris, manual iris or auto iris lens. The camera is factory set for a CS-mount
lens, but is easily adjusted for a C-mount lens.
1.
C-Mount Lens Only -
Rotate the back focus adjustment 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 AIV (auto iris video drive lens) or AID (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 auto iris lens to the four-pin connector located on the side of the camera.
Pin connections for the iris drive connector are as follows:

trim ring conceals the
LED light for more
discreet surveillance
operations. The trim
ring also hides the
power connectors and
protects the DIP
switches.
