Dip Switch Functions ALC Video GND Video GND ON ON LEVEL OFF LL AGC BLC FL OFF LL AGC BLC FL ES Board Lens Vari-Focal Lens LL (Line-Lock) Off/On To select the sync mode between Internal Sync.(LL off) and Line-Lock (LL on). Set the line-lock off, the camera will synchronize to the internal time base. Set the line-lock on, the camera’s vertical synchronization can be driven by the AC signal in the power lines.
BLC (Back Light Compensation) On/Normal When BLC is turned on, the AGC, ES and IRIS 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.
IRIS Level Adjustment Brightness Level can be adjusted from the IRIS level VR while using the direct drive lens. Turn counterclockwise to L to get darker picture. Turn clockwise to H to get brighter picture. IRIS ALC Adjustment To select light metering method – Turn the IRIS ALC Adjustment VR counterclockwise for Average Metering. Turn the IRIS ALC Adjustment VR clockwise for Peak Metering.
