1. C/CS mount Focus Switch 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 CS-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 for preventing losing focus.
4. DC Lens Connector (4 pin socket)
To connect to the lens plug of the auto iris lens.
5. Camera Setting DIP Switches
There are 6 DIP switches located on the sideboard, which are for camera setting. The
switches in order from top is Flickerless, Back Light Compensation, Electronic Shutter,
Automatic Gain Control, Line-Lock and Auto Iris Lens type. Please see camera DIP
switch setting section.
6. IRIS Level Control
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.
7. V-Phase Adjustment Screw
The vertical phase may require adjustment to synchronize the vertical phase of the camera
with other camera in the system when it is being used in the line-lock sync mode. Make the
adjustment when the vertical phase of the camera does not match with other cameras.

8. Mounting Base and Fixing Screws
The mounting base can be attached to either the top or the bottom of the camera, fix the
mounting base onto the camera by using the 4 fixing screws in the accessory pack.

INSTALLATION
1. Remove the lens cover cap.
2. If a C-mount lens is used, please make sure to turn the C-mount/CS-mount focus switch ring
at C position before fixing the lens.The default is CS mount.
3. Screw the lens firmly onto the lens mount. Insert the lens plug into the DC lens connector if
the auto iris lens is used.
4. Tighten the focus locking screw.
5. Connect the video output of the camera to a color monitor or other video device through a 75
ohm type coaxial cable with BNC female connector.
6. Connect the Power.
7. Once the image appears on the monitor, adjust the focus and diaphragm of the lens to obtain
the best picture.
8. If the subject is not in focus when adjusting focus of lens, turn the C-mount/CS-mount focus
switch ring to do focal length adjustment as following:
i. Loosen the locking screw of the focal length adjustment ring.
ii. Take picture of subject at a distance more than 20m away from the camera.
iii. Rotate the focal length adjustment ring to bring the subject in focus.
iv. Tighten the locking screw while the adjustment is completed.

Camera Setting DIPSwitch
Fluorescent ON/OFF
This is a compensation function for against the images flicker fiercely during fluorescent light
condition. Shooting the images in fluorescent light by using turn on the Fluorescent function,
the default setting is Off.
BLC (Back Light Compensation) ON/OFF
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 OFF.
ES (Electronic Shutter) OFF/ON
ES ON: The camera continuously adjusts the shutter speed from 1/60 (NTSC), 1/50 (PAL) second
to 1/100,000 second according to the luminance conditions of the scene.
ES OFF: The shutter speed is fixed at 1/60 (NTSC), 1/50 (PAL) 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: The cameras feature AC line lock for external synchronization, using the AC power

frequency (60Hz) is possible but not available in using DC or other operation power such as
NTSC in 50Hz or PAL in 60Hz power system.
VD/DD (Auto Iris lens Type)
For video drive auto iris lens, please set switch to VD. For direct drive iris lens, set switch to DD.
The default setting is DD. Wire the cable of lens to lens connector according to the following
