2.3 Optical Interface
The lens mount depends on the type of camera.
For XCM80160CXP, M72×0.75 screw mount is used. For XCM60160CXP,
XCM40160CXP, Nikon F mount is used.
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.

Depending on the frame grabber board, it is possible to connect up to four cameras
at the time of [writing].
＜Note : Choosing a coaxial cable＞
Please use a 75Ω coaxial 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 the coaxial cable and BNC
connector. We have been able to verify operation over 100m using the below
combination of coaxial cable and BNC connector:
Coaxial cable: L-5CFB (CANARE)
BNC connector: BCP-B5F (CANARE)

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.

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.

5 Camera Control
The camera can be controlled by the frame grabber board through the camera’s
control registers. The camera supports GenICam, and so can be easily controlled by
a GenICam-compatible frame grabber. The camera control software which came with
your frame grabber should be used for camera control.
Once the camera settings have been made and saved, the camera will operate
without further setting.
5.1 Flow of Camera Control
5.1.1 GenICam overview
The camera control register information is saved inside the camera (XML file)
The frame grabber board reads the XML file during Discovery, and acquires the
register information.
Camera control is enabled after Discovery.
5.1.2 Camera Control registers
The camera can be controlled the function through camera register by frame grabber
board.

5.4 Digital Processing flow in FPGA
The figure below shows the digital processing flow in the FPGA.
5.5 Startup
When you power on the camera, the camera goes through a series of startup
procedures. During startup, the LED lights orange.
The startup procedure is as follows.
① The camera initializes the hardware.
② Reads out the latest camera settings from the flash memory. (User settings if any
or factory default settings)
③ Sets up the camera with the setting values from the flash memory.
When this sequence finishes, the camera is ready to capture and output images. In
order to output images, the Discovery procedure must be done from the frame
grabber board.

5.6 Saving and Loading Camera Settings
The camera setting data is saved in the internal memory (flash memory) and is
loaded from the memory when turning on the power supply or loading.
The number of times the flash memory can be rewritten will vary depending on
actual operational conditions. After turning on the power supply, the camera always
checks the memory status. If the data is not within the designated range due to a
malfunction or other type of trouble, the memory will be automatically rewritten with
the factory settings.
If disconnecting camera power while rewriting the memory, all data saved in the
memory will be deleted.
As it takes several seconds to rewrite the memory, do not disconnect the power
supply before receiving the response from the camera.
Registers for rewriting the memory are as follows.
Reset to factory settings(User set_Reset To Factory Default)
Store present setup data in memory (User set_Lead)
Store pixel correction data in memory (Pixel Correct Data Save)
When changing the factory setting exposure mode, be sure to send the control
input signal (Trigger packet) from the frame grabber board. If you do not send or
sending control input signals are out of the designated range, you cannot get
images and can not change the setting. See 5.9.2 and 5.9.3.

Figure 5-7-1 Assignments of Digital Data
The A/D converter of the camera has a 10-bit resolution. For 8-bit output, the upper
8-bit signal can be output as a video data.
5.8 XML file
The XML file is a file saved in the camera which contains the register information
described in chapter 5.
According to the CoaXPress specification, when “Device Discovery” is performed
from the camera control software supplied with the frame grabber, this file is read
out, and the camera control registers are displayed in the camera control software
(in the case of some manufacturers, they may not be displayed)
However, if the frame grabber does not support GenICam, this function is not
available.

5.12 Pixel Correction
As a rule, image sensors (CCD, CMOS and so on) have fixed pattern noise and
photo response non-uniformity. Lens shading and light sources can also cause
non-uniformity. The camera is set to the optimal correction before shipping in order to
provide images of the highest grade.
The camera also has a user white correction function to cope with lens shading and
non-uniform illumination, or to be able to completely clear the uneven brightness
generated by changing the spectral response level of the light source. Cal_bl:
Output data of each pixel at perfectly dark (digital) Cal_wh: Output data of each
pixel in uniform illumination (digital) Target_Val : Target value for correction (10bit
digital) Vin : Input data (digital) Vout : Output data (digital) The corrected data is
expressed in the following equation. Vout=(Vin-Cal_bl) x Target_val /

6.3 During Operation
(1) Does an acquisition time out error occur?
<Cause>
<1> Captured images are too large.
If there are many filtering processes, the assignments to the driver may be
insufficient.
<2> The cable is detached from the connector
Ensure that the power cable and coaxial cables are connected to the camera firmly.
<3> Camera Link cables are susceptible to noise when the cables are laid near a
light source inverter line or a power line. The personal computer in use may be
freeze and need to be reset.
(2) Are there dark lines in the direction of vertical scanning on the image?
<Cause>
<1> Dust on the sensor window
Dust may get onto the sensor window from the inside or the outside of the camera.
Remove the dust with air or a lens cleaner.

7 Dynamic Range Control (Multi-Slope Mode)
By setting the “ExposureMode” register to “Multi Slope”, it is possible to change the
slope of the photoelectric conversion curve at multiple points in order to increase the
dynamic range of captured images. In this mode, the registers “MultiSlope_Level1, 2, 3”
set the knee point levels of the linear response, and “MultiSlope_Timing 1, 2, 3” set the
integration time of each slope. The greater the integration time ratio, the more the
dynamic range is extended; however the minimum value should not be less than 1.
This function only operates in Exposure Mode “Multi Slope” (5.3.4). This function
cannot be used in “Free Run” mode or external trigger modes (“External egde”,
“External level”).
The scan cycle becomes longer than normal
7.1 MultiSlope Mode Default Setting Operation
Let us take as an example 5 levels of light intensity (Strong: A ~ Weak: E). The 5
coloured lines/dots labeled intensity A~E illustrate light entering the camera during the
exposure time period set by “ExposureTimeCounter”.
The default settings are as follows:
MultiSlope_Timing1: 0, MultiSlope_Timing2: 1, MultiSlope_Timing3: 10
MultiSlope_Level1: 0, MultiSlope_Level2: 5, MultiSlope_Level3: 10
ExposureTimeCounter: 61
1. Exposure starts at exposure time 0
2. At exposure time 50, the signal is reset to 1/3 of the saturation level. “Reset”
means that any signal above the set value (in this case 1/3 of the saturation level)
is discarded. With this first reset, the portions of signals A-C which exceed the 1/3
saturation level are discarded, but D-E are unaffected.
3. With a further exposure time of 10 (from 50 to 60), the signal is reset a second
time to 2/3 of the saturation level. With this second reset, the portion of signal A
which exceeds the 2/3 saturation level is discarded. There is no effect on B-E
from this reset.
4. Exposure stops at exposure time 61.
*Actual settings & exposure times may vary depending on the camera model being used

After the second reset, the line characteristics change such that it bends at the pink and
green points (shown in the figure above right). In the case of the blue line in the figure
above left, without Multi-slope, the photoelectric conversion function is a straight line to
A’, and the camera is saturated with incident light. By curving the linear response of the
photoelectric conversion, this can be changed to line A. Similarly, the green changes
from B’ to B, and orange from C’ to C. In this case, the light exposure of pink and red
need no change.
By doing this, even with large amounts of incident light that would normally cause
saturation, it is possible to turn it into a signal without saturation, resulting in a wide
dynamic range image.

[The following guide uses the XCM80160CXP as an example]
7.2 Standard Mode
The minimum line period is 53.6 μsec. The dynamic range is determined by the sensor’s
saturation output and dark output. The sensor specification is 60dB.

7.3 1 When bending the response curve
① To set the integration time ratio of each slope to 10, use the following settings:
ExposureMode: MultiSlope
MultiSlope_Level1: 0, MultiSlope_Level2: 0, MultiSlope_Level3: 8
MultiSlope_Timing1: 0, MultiSlope_Timing2: 0, MultiSlope_Timing3: 10
ExposureTimeDividing: 16
ExposureTimeCounter: 110
As can be seen in the figure below, the integration time of the first slope will be 100
(110-10), the integration time of the second slope is 10, and the reset level is half the
saturation level. Note that as the reset level increases, the output of the graph below
becomes smaller.
The minimum line period becomes 92.8 μsec. The dynamic range increases 5.5 times
(Saturation level ratio: 0.55/0.1) to 75dB (60dB + 20log5.5=74.8)

②To set the integration time ratio of each slope to 5, use the following settings:
ExposureMode: MultiSlope
MultiSlope_Level1: 0, MultiSlope_Level2: 0, MultiSlope_Level3: 8
MultiSlope_Timing1: 0, MultiSlope_Timing2: 0, MultiSlope_Timing3: 11
ExposureTimeDividing: 16
ExposureTimeCounter: 66
As can be seen in the figure below, the integration time becomes 55 in the first slope,
11 in the second slope, and the reset level is half the saturation level. The minimum
line period becomes 57.6 μsec. The amount of saturation exposure is 0.05+0.25=0.3.
The dynamic range becomes increases 3 times (Saturation level ratio: 0.3/0.1) to
69.5dB (60dB + 20log3=69.5)

7.4 Bending the line three times
① For an integration time ratio of 10, use the following settings:
ExposureMode：「Multi Slope」

MultiSlope_Timing1：1, MultiSlope_Timing2：10, MultiSlope_Timing3：100
ExposureTimeDividing ：16
ExposureTimeCounter：1023
The integration time becomes 1000 in the first slope, 100 in the second slope, 10 in the
third and 1 in the fourth. The reset levels become ¼, ½, ¾ of the saturation level, as the
diagram below indicates.
The minimum line period is 823.2us. The dynamic range becomes 284 times 1 (ratio of
saturation exposure amount: 28.4/0.1), i.e. 109dB (60dB + 20log284 = 109)

ExposureTimeCounter：156
The integration time becomes 125 (156-(1+5+25) in the first slope, 25 in the second
slope, 5 in the third slope and 1 in the fourth slope. The respective reset levels become
¼, ½, ¾ of the saturation level, as the diagram below indicates. The minimum line
period becomes 129.6us. The dynamic range becomes 39 times 1 (ratio of saturation
exposure amount: 3.9/0.1), i.e. 92dB (60dB + 20log39 = 91.8).

8 Sensor Handling Instructions
8.1 Electrostatic Discharge and the Sensor
CMOS sensors are susceptible to damage from electrostatic discharge and can
deteriorate as a result. Take care when handing the sensor.
8.2 Protecting Against Dust, Oil and Scratches
The CMOS sensor window is part of the optical path and should be handled like other
optical components with care. If you use the camera in a dusty area, prepare a
dust-proof enclosure. Dust can obscure pixels, producing dark lines on the image.
8.3 Cleaning the Sensor Window
Cleaning the Sensor Window
Dust: Can usually be removed by blowing the window surface using a compressed air
blower.
Oil: Wipe the window with a lint-free cloth wiper moistened with ethyl alcohol carefully
and slowly.
