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 connec-
tions for the iris drive connector are as follows:
PIN DC (AID) AUTO IRIS LENS VIDEO (AIV) AUTO IRIS LENS
1 Control coil negative (-) Lens positive supply
2 Control coil positive (+) Not used
3 Drive coil positive (+) Video drive signal
4 Drive coil negative (-) Ground

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