Major Parts Names and Their Functions

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) 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 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.

ES (Electronic Shutter) Off/On

ES ON: The camera continuously adjusts the shutter speed from 1/60 (EIA),

1/50(CCIR) second to 1/100,000 second according to the

luminance conditions of the scene.

ES OFF: The shutter speed is fixed at 1/60 (EIA), 1/50 (CCIR) second.

Set ES OFF, when auto iris lens is used or flicker is observed under a very

bright fluorescent lamp. Otherwise, turn ES on for optimum performance.

The default setting is ON.

AGC (Automatic Gain Control) Off/On

AGC ON: The sensitivity increases automatically when light is low.

AGC OFF: A-low-noise picture is obtained under a low light condition.

The default setting is ON.

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.

Note: Line-Lock sync mode operation is possible only when used with an

AC power source; it’s not possible with a DC power source.
