Instructions before use
Only operate this product within the recommended environmental temperature
range.
Use only the specified power source and voltage rating.
Do not drop this product. Avoid exposure to strong impact and vibrations.
Install the camera unit in a well-ventilated environment, in order to prevent the
camera from overheating.
If the camera must be installed in an environment containing dust or other
particles, take required measures to protect the camera unit from dust
adhesion.
Do not unplug the cable while power is being supplied to the camera unit. To
prevent product damage, always shut down the power supply before
unplugging the power cable.
When the surface of the camera window becomes dirty due to dust or grime,
black smudges appear in the displayed image. Use an air blower to remove the
dust particles. Dip a cotton swab into ethanol alcohol and clean the camera
window. Be careful not to scratch the glass.
Use of non-infrared lighting such as a daylight fluorescent lamp is
recommended. If halogen lighting is employed, always install an infrared filter
into your system configuration.
Please note that exposure to long wavelength light outside of the sensors
visible optical range can affect the image.
For stabilized image capturing, turn ON the power supply and execute aging for
ten to twenty minutes before actually using the camera unit.
Do not share the power supply with motor units or other devices that generate
noise interference.
Do not disconnect the camera while rewriting the embedded memory.
When you change the exposure mode that is set at the NED factory, input
control signal (CC1) from the capture board.
SG (Signal Ground) and FG (Frame Ground) are connected inside the camera.
Please install your system such that a loop is not created by the GND potential
difference.

2 Camera Setting and Optical Interface
2.1 Setting Camera
Use the M4 screw holes or the screw hole for a tripod to set the camera.
2.2 Fixing Camera
Use the M4 screw holes (4 places at the front, 8 places at the side) to fix the
camera. Or use the 1/4"-20UNC screw hole (the screw hole for a tripod, 1 place
at the side) to fix the camera.
If using the front panel M4 mounting holes, the screw length for fixing the
camera should be less than 6mm.
No X-, Y-axis orientation and tilt adjustment mechanism is available. Please
provide an adjustment mechanism yourself as necessary.
The dimensions for camera are shown below.

2.3 Optical Interface
The lens mount depends on the type of camera.
The amount and wavelengths of light required to capture useful images depend
on the intended use. Factors include the property, speed, the object’s spectral
characteristics, exposure time, the light source characteristics, the specifications
of the acquisition system and so on.
The exposure amount (exposure time x light amount) is the most important
factor in getting desirable images. Please determine the exposure amount after
studying what is most important to your system.
Keep these guidelines in mind when setting up your light source:
LED light sources are relatively inexpensive, provide a uniform field and
longer life span compared to other light sources. However, they also
require a camera with excellent sensitivity.
Halogen light sources generally provide very little blue relative to infrared
light (IR).
Fiber-optic light distribution systems generally transmit very little blue light
relative to IR.
Metal halide light sources are very bright but have a shorter life span
compared to other light sources.
Generally speaking, the brighter light sources, shorter life span.
CMOS image sensors are sensitive to infrared (IR). We recommend using
daylight color fluorescent lamps that have low IR emissions. If you use a halogen
light source, to prevent infrared from distorting the images use an IR cutoff filter
that does not transmit IR wavelengths.

3 Hardware
3.1 Camera Connection
Camera Link cables shall be used to connect the camera unit with the frame
grabber board.
1. Connect the camera to the PC with a LAN cable.
Notes:
1)Please use a CAT-5e or higher grade LAN cable to connect the camera to the
PC.
2)In countries requiring CE certification, please use a shielded cable.
3)Please use a Gigabit Ethernet compatible LAN port.
To add additional cameras use a NIC (Intel: Gigabit CT Desktop Adapter
EXPI9301CTetc.) on the PCI or PCI-Express bus.
2. Connect the power to the camera.
Note:
Use a power cable to connect the camera power to the camera. Connect the
plug end of the cable to the camera, and the open end to the power supply. In
addition, a lens, lens mount, illumination, trigger controller, etc may be
required. Please choose equipment suitable for your application’s
requirements.

The camera requires a single power supply (DC+12 to +15V).
When selecting a power source, choose one with the capacity to allow
for inrush current. (15W or more recommended)
Insert the cable plug securely until it locks into position. This is to prevent
the connector from coming loose during power transmission.
Do not remove the cable while image data is being transmitted.
