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 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. Moreover, this irregular sensitivity can be
completely lost by using 4.11 pixel correction function. Please refer to 4.11 pixel
correction function for details.
Please note that when the sensor 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 an embedded memory.

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

2.3 Optical Interface
The XCM2085DLMT2 comes with a C-Mount as standard, but an F-Mount can be
chosen as an option.
1) Quantities of light and the wavelength etc. of a source of light necessary to take the
image for which the customer hopes are different according to the usage. The factor to
decide these contains physical properties, the speed, the spectrum characteristic of
the object taken a picture of, the exposure time, and the characteristic of the source of
light and the specification etc. of the taking system.
It is a luminous exposure (exposure time × quantities of light) that it is important
because an appropriate image is obtained. Please decide the exposure time and
quantities of light after examining which element the customer values enough.
2) 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 light but have high infrared
light (IR) proportions.
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.
3) Generally speaking, the brighter the light sources, the shorter the 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 cut off filter that does not
transmit wavelengths.

The deviation from the target pixel slope line is shown in the following table, as a
result of having measured ten randomly selected samples.

3 Hardware
3.1 Camera Connection
1. Connect the camera to the frame grabber board in the PC with the Camera
Link cables.
Notes:
1) Use asymmetric Camera Link cables
2) Connect the camera with the connector labeled as “Camera side” if Camera
Link cables have transmission direction.
2. Connect the power to the camera.
Notes:
Use a power cable to connect the camera with the power source. Connect the
plug end of the cable to the camera, and the open end to the power supply.
In addition, a personal computer, the frame grabber board, a lens, lens mount,
a light source and an encoder, etc. may be required. Please choose equipment
suitable for your application.

XCM2085DLMT2 UME-0059-02
<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.
