Pelco Manual C1961M-B (3/01) 7
GENERAL LENS INFORMATION
The CCC1300H-2, CCC1300H-2X, and MCC1300H-2 can use fixed, manual, or passive
(DC-controlled) auto iris lenses. The camera has a standard CS lens mount, but can use
a C-mount lens when a C/CS-mount adapter is installed between lens and camera.
LENS MOUNTING
1. 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, com-
pressed air to remove any foreign matter.
2. Aim the camera and focus the lens to the object or area to be observed.
3. If a manual iris lens is used, adjust the iris for the best picture quality. The largest
aperture gives the best light sensitivity, the smallest aperture the greatest depth
of field.
AUTO IRIS LENSES
Passive auto iris lenses are DC-controlled via the 4-pin iris drive connector (type D4-
152N) located on the back of the camera. Pin connections for the iris drive connector
are as follows:
PIN VIDEO SIGNAL CONTROL DC VOLTAGE CONTROL
1 +9 VDC (40 mA max.) Control coil (-)
2 +9 VDC (40 mA max.) Control coil (+)
3 AI - Video Drive coil (+)
4 GND Drive coil (-)
BACK FOCUS ADJUSTMENT
Do not release the back focus locking ring unnecessarily. Back focus adjustment has
been set at the factory to the standard CS-mount back focus distance. However, once
a lens is mounted it may be necessary to adjust back focal length to match the lens
being used.
FIXED FOCAL LENGTH LENSES
1. Mount the lens firmly to the camera.
2. With the camera operating, position the camera to view an object at least 30 feet
(10 m) away.
3. Set the focus ring to infinity (∞).
4. Set the lens iris to its widest usable opening.
