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:
Completely rotate the back focus adjustment counterclockwise before
installing the C-mount lens (refer to
Back Focus Adjustment
on page 14).
2. 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
Switch Settings
on page 15. Switch settings are 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. Connect the auto iris lens to the 4-pin connector located on the side of the camera. Pin connections
for the iris drive connector are as follows:
