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:

3	4	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
1	2	4	Drive coil negative (-)	Ground
