digital device, in accordance with Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference,
in which case the user will be required to correct the interference at his or her own
expense.

Introduction
Thank you for purchasing NED’s Line Scan Camera. We look forward to your
continued custom in the future.
For safety use
◆For your protection, please read these safety instructions completely before
operating the product and keep this manual for future reference.
◆The following symbols appear next to important information regarding safe product
handling.
Warning
If the product is not handled properly, this may result in
serious injury or possible death.
Caution
If the product is not handled properly, this may result in
physical injury or cause property damage.
Safety precaution
Warning
◆Never disassemble or modify this product, unless otherwise specified to do so in
this manual.
◆When hands are wet, avoid handling this product and do not touch any of the
connection cable pins or other metallic components.
◆Do not operate this product in an environment that is exposed to rain or other
severe external elements, hazardous gases or chemicals.
◆If the product is not to be used for an extended period of time, as a safety
precaution, always unplug the connection cable from the camera unit.
◆If the product installation or inspection must be executed in an overhead location,
please take the necessary measures to prevent the camera unit and its
components from accidentally falling to the ground.
◆If smoke, an abnormal odor or strange noise is emitted from the camera unit, first
turn OFF power, then unplug the cable from the camera unit.
◆This product is not intended for use in a system configuration built for critical
applications.

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 fluorescent lamp is recommended. If halogen
lighting is employed, always install an infrared filter into your system configuration.
◆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. Moreover, this irregular sensitivity can be
completely lost by using 4.8 pixel correction function. Please refer to 4.8 pixel
correction function for details.
◆Note that when the sensor is exposed to excessive quantities of light, blooming
may occur, because this product does not have a special Anti-Blooming function.
◆Suitable measures should be taken to protect the colour filter on sensor from bright
light when it is not in use.
If the sensor is continually exposed to excessive amount of light over time, the
colour filter may become faded.
◆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.

2.1 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.

2.3 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, 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.

2.4 Calibration with User White Pixel Correction Function
This camera is set to the optimal pixel correction with a daylight fluorescent lamp
(NEC FL20SD) before shipping.
Light sources and lens shading can cause non-uniformity.
Calibrate the camera with a user white pixel correction function to cope with lens
shading and non-uniform illumination by following below steps.
1) Set the lens and light source which you want to use.
2) Set NED_FFCMode to "Factory White".
3) Adjust the exposure time and gain to set the signal level to about 200 DN.
4) Execute NED_PRNUCalibration.
5) Change NED_FFCMode to "User White".
This calibration can improve the white balance and the waveform flatness of
the camera signal.
See below for more details.
