1. Focal Length Adjustment Ring
Use this ring to adjust the appropriate focal length according to the type of
lens. Rotate the ring clockwise for the CS-mount lens, rotate it
counterclockwise for the C-mount lens. The factory setting is C-mount.
2. Lens Mount
To mount an appropriate C-mount or CS-mount lens.
3. Locking Screw
Use the locking screw to fix the focal length.
4. Lens Connector (4 pin socket)
To connect to the lens plug of the auto iris lens.
5. Control Switches
There are 6 control switches located on the sideboard, which are for the
setting of the special features. The switches in orders are for Flickerless,
Back Light Compensation, Electronic Shutter, Automatic Gain Control,
Line-Lock and Auto Iris Lens type.
FL (Flickerless Function) On/Normal
When picture flicker fiercely, turn FL on, then the camera will stabilize the
speed of electronic shutter at 1/100(EIA) or 1/120(CCIR) automatically, and
reduce the flicker immediately. The default setting is Normal.
BLC (Back Light Compensation) On/Normal
When BLC is turned on, the AGC, ES and IR IS operating point is
determined by averaging over the center area instead of entire field-of-view,
so that a dimly-lit foreground object at center area can be clearly
distinguished from brightly-lit backgrounds.
BLC should not be used unless it is needed to compensate for back-lit. The
default setting is Normal.
