 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.

XCM20160T2CXP UME-0054-01
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.
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 (Trigger packet) from the capture board.

2.3 Optical Interface
This camera is equipped with a Nikon F mount.
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.
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.

3.1 Camera Connection
 Depending on frame grabber board; up to two cameras can be connected to a
frame grabber board with operating mode - XCM20160T2CXP, and up to four
cameras can be connected for operating mode - XCM20160CXP.
<Note: Choosing a suitable coaxial cable>
Use a 75Ωcoaxial cable with a BNC connector according to the CoaXPress
standard.
The maximum cable length is not prescribed by the standard. The maximum
cable length to be able to transfer data depends on factors such as a attenuation,
diameter and manufacturer.
We recommend that you use a standard approved cable.
Refer to JIIA (http://jiia.org/cxp/) for more information about standard approved
cables.
As specifications for each manufacturer differs, please contact the cable
manufacturer directly for details.

3.3 Power Supply
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.
Compatible Cable (Compatible plug): DGPSA-10 (HIROSE: HR10A-7P-6S )
Power supply voltage: DC+12-+15V ( +/- 5%)
Consumption Current (rated): DC+12V: 600mA
The LED lamp illuminates when +12V to +15V power is being supplied to the
camera.
If the lamp fails to illuminate even after power is supplied, turn OFF power
immediately. Inspect wiring. Check the voltage and capacity of the supplied power
source.

Unable to process commands (System crash) : Blinks red
Transmitting image packets (Acquisition Start =1) : Lights green
Not transmitting image packets (Acquisition Stop =1) : Blinks green
* When the scan rate is close to 1.6s, the LED may flash orange and green alternately.
When Acquisition Start and Stop are performed repeatedly, the green LED may
appear to be flashing.
* Moreover, when repeating the operation rapidly, the green LED may appear dark.

4 Camera Startup
4.1 Camera Startup Procedure
This camera does not immediately output stream data packets (image data) after
powering on. In order to output stream data packets, it is necessary to perform Device
Discovery (Camera and Frame Grabber connection).
Please check your frame grabber’s manual for how to perform device discovery.
The below example uses Matrox’s Radient eV-CXP as an example. The Radient
eV-CXP performs device discovery on opening a “DCF” file.
1. Open Intellicam from the Matrox Imaging Library
2. From the Intellicam “File/Open” Menu, open “DefaultLineScan”
3. If the contents of the DCF file are displayed, then discovery has been performed
successfully.
