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.
Sensitivity may fluctuate depending on the spectral response level of the light
source. In cases like this, changing the light source to one with a different
spectral response level may reduce this problem.
Please note that when the CCD is exposed to excessive quantities of light,
blooming can occur. (this product does not have an Anti-Blooming function)
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.

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.

2.4 Optical Interface
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, the shorter life span.
CCD 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
(1) Camera Link cables shall be used to connect the camera unit with the frame
grabber board.
If you use asymmetric Camera Link cables, connect the camera with the
connector labeled as ”Camera side”.
(2) Connect with a power supply.
Use a power cable to connect the camera with the power source for the
camera. Insert the plug end of the cable into the camera. Attach the opposite
end (loose wires) to the power unit.
Other than the above, a personal computer, a frame grabber board, a
photographic lens, a photographic lens mount, a light source and an encoder
are necessary, depending on the situation。

<Note: Choosing the appropriate Camera Link cable length >
According to the Camera Link Specification, the maximum cable length is 10m. But
the maximum cable length to be able to transfer data depends on the type of cable
performance and clock speed. The actual maximum transmission distance becomes
less than 10m at faster clock speeds, though the transmission distance of 10m is
feasible at slower clock speeds.
The following table shows values being calculated in accordance with the Camera
Link Specification 2007.Version1.2., using a typical cable (14B26-SZLB-xxx-0LC from
3M) and frame grabber board (Solios from Matrox). Please choose the appropriate
Camera Link cable type and length for your application. We recommend you perform
a connection test in advance.
