The CV-L108CL follows the Camera Link standard in all respects.
Please refer to the Camera Link version 1.1 specifications for detailed information on bit
assignments of 24-bit RGB and 30-bit bit output.
5.3. Input and output circuits
5.3.1. Trigger input
The External Trigger signal can be applied either through the Camera Link connector or at pin 10 of
the 12-pin Hirose connector. The command to change this setting is TI (Trigger Input). TI=0 for
Camera Link connector (factory default) and TI=1 for 12-pin Hirose connector. The input via the
12-pin Hirose connector is AC coupled.
To allow long pulses, which may be required when using the Pulse Width Control (PWC) trigger
mode, the input circuit is designed as a flip-flop circuit. The leading and trailing edges of the trigger
pulse activate the circuit.
The trigger input polarity can be changed by the command TP. At the 12-pin Hirose connector the
External Trigger input is 4V ± 2V (TTL). It can be changed to 75 ohm termination by an internal
switch setting (SW 801-2).
Fig. 4 Trigger input (12-pin Hirose)

5.3.2. EEN / XEEN output (Exposure ENable)
This output corresponds to the exposure (accumulation) time of the camera. It works together with
all operation modes. It is, however, not active when the test pattern function is enabled.
The EEN signal is available at the Camera Link connector and at the 12-pin Hirose connector at the
same time.
At the Camera Link connector this signal has positive logic.
At pin 9 of the 12-pin Hirose connector the signal has negative logic, and is therefore named XEEN.
The output circuit is a 75 ohm complementary emitter follower. The circuit is powered from the 5V
supply, resulting in an output level of more than 4V. It is not terminated.

6. Functions and Operation
6.1. Basic functions
The CV-L108CL is built around three high-performance CCD line scan image sensors mounted on a
prism block, as illustrated in Figure 6.
During exposure, the incoming light is converted to electrons (electric charge) in the photodiodes
(active pixels). The transfer gate controls the transfer of charge from photodiodes to the shift
register. Activating the transfer gate terminates the exposure cycle, transfers the charge to the
Horizontal Shift Register (2-phase buried channel CCD shift register) and starts a new exposure
cycle. The line is subsequently read out in a single sequence starting with pixel 1.
The exposure time is normally the same as the cycle time (in No-Shutter mode). By using the
Exposure Control Gate (in Shutter-Select or Pulsed Width Control trigger modes) the exposure time
can be individually set to be shorter than the cycle time (the inverse of line rate). This also allows a
fixed exposure time, independent of the line rate. In the CV-L108CL the exposure time can be set
individually for all three channels.

6.2. Pixel Gain (flat-field) correction (PRNU correction)
Pixel Response Non-Uniformity is, as the name expresses, a non-uniformity of the response of each
individual pixel. This means that for a fixed light level each pixel will have a slightly different
output level (response).
To correct for PRNU, the camera‟s internal correction circuit captures one or several lines of data
under non-saturated illuminated conditions (not more than 80% of maximum - recommend level is
half of maximum), and the average across the line is calculated. Based on this average, coefficients
are then generated for each individual pixel. The coefficient has the function of multiplying the
pixel output with factor greater or less than 1. These coefficients are stored in a non-volatile
memory, and are therefore maintained after power down.
6.3. Pixel black level correction (DSNU / FPN correction)
Dark Signal Non-Uniformity or Fixed Pattern Noise is, as the name expresses, fixed pattern on the
sensor output, which is not dependent on the incoming light.
To correct for DSNU/FPN, the camera-internal correction circuit captures one or several lines of
data under dark conditions (the lens must be covered by a lens cap), and the average across the line
is calculated. Based on the average, coefficients are then generated for each individual pixel. The
coefficient has the function of adding or subtracting a value to the pixel output. These coefficients
are stored in a non-volatile memory, and are therefore maintained after power down.
As the dark signal is highly dependent on the exposure time, this correction must be performed
under the operating conditions (exposure time and line rate) that will be used by the application.

6.4. Shading correction
Shading is caused either by illumination with uneven distribution of light across the surface, or by
vignetting towards the edges of a lens.
The shading correction incorporated in the camera will compensate for this effect by as much as
20% of the brightest signal.
Shading is not compensated for each individual pixel. The signal is averaged across groups of 8
pixels in relation to the whole line. The pixel response non-uniformity will be superimposed on the
output also after shading correction has been performed. Therefore, it is recommended to perform
a pixel gain (flat-field) correction after shading correction.
The Pixel Gain (flat-field) correction function is also used to compensate for shading, but it cannot
handle a very wide dynamic range.
The shading correction can be configured to compensate each channel separately or can track the
green channel.
6.5. Binning
The binning function in this camera combines the charge collected in two adjacent pixels. This
halves the effective resolution to 256 pixels, but doubles the sensitivity. The line rate is not
affected by binning.

6.6. Operation modes
The CV-L108CL provides three basic modes of operation: No-shutter, Shutter-Select and Pulse Width
Control (PWC). The Shutter-Select and PWC modes also allow the user to set the exposure time
independently from the scan rate, by making use of the electronic shutter (the Exposure Control
Gate of the CCD sensor).
The following sections describe these modes. The detailed timing of the video output, shown in
figure 8, is common to all modes.
Fig.8 Video output timing
CV-L108CL
14
6.6.1. No-Shutter mode with internal line rate generator
In this mode the camera does not accept an external trigger signal, as the line rate is generated
from an internal clock (user programmable, command LR). The exposure time is directly
proportional to the line rate (T
exp
= 1/line rate). This mode is used when there is no external trigger
signal available, and the speed of the object is fixed or can be pre-determined.
The line rate can be varied from 1 line period (L) to 1024L in 1 clock (25ns) steps, 14.1μs to 14.438
ms. When using this mode, a special function called “One-push auto line rate” is available. This
mode automatically maintains a constant output level by changing the line rate. See chapter 7
(configuring the camera) for further details on this function. The line rate is automatically adjusted
in order maintain sensitivity without reducing the S/N ratio.
To use this mode:
Set function Trigger mode, No-Shutter TR=0
Trigger origin, internal TG=0
Line rate LR=564 to 577536
(14.10 µs to 14.438 ms in 25ns increments)
Optional functions when using this mode:
One-push auto line rate AR=0
Auto line rate reference AL=0 to 1023
One-push white balance WB
Fig. 9 No-Shutter mode with internal line rate generator
Important Note
The “one-push auto line rate” function is not recommended for continuous web applications, as
the speed of motion needs to be adjustable in order to maintain the aspect ratio of the image.
Only gain based One-push white balance functions (WB) is available with this mode.
CV-L108CL
15
6.6.2. No-Shutter mode with external trigger
In this mode, the exposure time is directly proportional to the line rate. The line rate is generated
externally by a trigger signal. This mode is used when an external trigger signal is available, e.g.
from an encoder, and the scan rate can be controlled by this signal. The camera can accept an
external trigger through the Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger mode, No-Shutter TR=0
Trigger origin, external TG=1
Trigger input TI=0 or 1
Important note:
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and duty
cycle used in the application.
Minimum trigger interval is 14.2 μs
Fig. 10 No-Shutter mode with external trigger
CV-L108CL
16
6.6.3. Shutter-Select mode with internal line rate generator
This mode allows the user to have full control of the line rate and the exposure time individually, by
programming separate timing generators. Subsequently the camera does not accept an external
trigger signal in this mode.
To use this mode:
Set function Trigger mode, Shutter-Select TR=1
Line rate LR=14.2 μs to 14.438 ms
Trigger origin, internal TG=0
Individual R, G and B exposure EI=0(individual)
EI=1(tracking with G)
Programmable exposure PER/PEG/PEB=2 to 577536
(50 ns to 14.438 ms in 25ns steps)
Important note:
If using individual exposure, the EEN signal represents the channel with the longest exposure time
The maximum exposure time is that of setting line rate.
Fig. 11 Shutter-Select mode with internal line rate generator (and individual exposure)
CV-L108CL
17
6.6.4. Shutter-Select mode with external trigger
This mode allows the user to have full control of the exposure time, by programming a timing
generator, while the line rate is controlled by an external trigger signal. The camera can accept an
external trigger through the Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function Trigger TR=1
Trigger origin, external TG=1
Individual R, G and B exposure EI=0(individual)
EI=1(tracking with G)
Programmable exposure PER/PEG/PEB=2 to 577536
(50 ns to 14.438 ms in 25ns steps)
Important note:
If using individual exposure, the EEN signal represents the channel with the longest exposure time
The minimum trigger interval is 14.2 μs
The maximum exposure time is the interval of trigger.
Note: Minimum period T1 is 30 clk.
Fig. 12 Shutter-Select mode with external trigger (and individual exposure)
CV-L108CL
18
6.6.5. Pulse Width Control (PWC) mode
In this mode, the user has full control of both the line rate and the exposure time of each line via
the External Trigger input.
At the falling edge of the External Trigger signal, the exposure is initiated, and at the rising edge
the exposure is terminated and read out. The camera can accept an external trigger through the
Camera Link connector or through the 12-pin Hirose connector.
To use this mode:
Set function Trigger mode, PWC TR=2
Important Note:
Possible pulse width:
TTL input (HIROSE 12-pin) 50 μs to 1 sec.
CC1 input (Camera link) 2 μs to 1sec.
The minimum trigger interval is “exposure time + 14.2 μs”.
One-push white balance by gain setting only.
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and duty
cycle used in the application.
Fig. 13 Pulse Width Control mode
CV-L108CL
19
6.6.6. Auto Reset mode
In this mode, when the interval of the trigger pulse is more than 55ms, the CV-L108CL automatically
returns to continuous operation with the line rate of 14.10μs . At this time, DVAL and Video OUTPUT
are disabled in order to prohibit charge due to dark current to add up in the sensor in standby
periods.
While the Auto Reset mode is “ON”, if the trigger interval becomes less than 55ms, CV-L108CL
operates in the original trigger mode selected.
Note: CV-L108CL functions properly according the selected operation mode while the Auto
Reset mode is “ON”. However, if the system uses LVAL, it is recommended to set the Auto

8.19 Command NOSR – Noise reduction
This function deletes the noise component of less than 16LSB composed in the signal.
This circuit used in the CV-L107CL minimizes the deterioration of the spatial frequency.
The improvement depends on the object and it will be approx. 3dB.
Settings 0=ON, 1=OFF
8.20 Command PBC – Enable pixel black (FPN) correction
This command enables (or disables) the “pixel black level” correction function, which
compensates for Dark Signal Non Uniformity / Fixed Pattern Noise (DSNU / FPN) for
individual pixels.
Settings: 0 = Off
1 = Factory setting
2 = user area
Associated functions: Command PBR
Applicable modes: All
8.21 Command PBR – Run pixel black correction and store to user area
This command initiates the “pixel black level” correction function, and stores the settings
in the user area. When this function is activated, lens must be capped.
Settings: 0 = Run this function
Associated functions: Command PBC must be set to 2
Important note:
This function requires that no light reaches the image sensors. The lens must therefore
be covered by a lens cap, or put the F-mount protective cover on the camera, when
executing this function.
As the black level is influenced by the exposure time (especially for long exposure time,
at slow scan rates) it is recommended to perform the pixel black correction at the
exposure time and line rate at which the camera will be operated.
8.22 Command PER – Programmable exposure – Red
This command allows individual setting of the exposure time of the Red channel. It is only
valid for the Shutter-Select mode (see chapter 6.2)
Settings: 2 to 577536, 50 ns to 14.438 ms in 25ns steps
Associated functions: EI (R and G exposure interlocked with G)
The actual Exposure time (ns) is calculated as follows:
T
exp
= 25ns x (Repetition period ([Parameter]) – (T1 ([Parameter]) +21 [Parameter]) )
8.23 Command PEG – Programmable exposure – Green
This command allows individual setting of the exposure time of the Green channel. It is
only valid for the Shutter-Select mode (see chapter 6.2)
Settings: 2 to 577536, 50 ns to 14.438 ms in 25ns steps
Associated functions: EI (R and G exposure interlocked with G)

8.25 Command PGC – Enable Flat-field correction (Pixel gain)
This command enables (or disables) the “pixel gain” (flat-field) correction function, which
compensates for Pixel Response Non Uniformity (PRNU) for individual pixels.
Settings: 0=Off
1=Factory Setting (default)
2=User area
Associated functions: Command PGR
Applicable modes: All
8.26 Command PGR – Run Flat-field correction and store in user area
This command initiates the flat-field correction function, and stores the settings in the
user area.
Settings: 0= activate automatic process
Associated functions: Command PGC must be set to 2
Important note:
The image sensors must not be saturated when executing this function.
When executing this function, the exposure time and line rate should be the same as
when the camera is operated in the application.
Operating procedure for individual R, G and B channel shadings correction:
1. Before making adjustment, it is required approximately 30 minutes warming up.
2. Make sure the output signal is not saturated (80% of full output is recommended)
3. Set command PGC=2 .
4. Set command PGR to 0 to initiate shading correction.
5. If desired, set command SDR to 0 or 1 to activate shading correction to correct the
shading caused by lens or lighting. When the shading correction is performed, the flatfield correction must be activated before the shading correction is performed.
8.27 Command SDC – Select shading correction mode
This function enables (or disables) the shading correction.
Settings: 0 = off (Bypass)
1 = Factory setting (default)
2 = User area
Associated functions: Commands PGR, SDR and SDS
8.28 Command SDR – Run shading correction
This function initiates automatic shading correction, and stores the result to the user area.
This function should be used together with the flat-field correction (commands PGC and
PGR). There are two types of shading correction: Individual R, G and B channel correction
and chromatic shading correction.
(A) Individual R, G and B channel correction (SDR=0)
Shading is calculated and individually compensated for R, G and B channels respectively.
CV-L108CL
31
The calculation is based on the average value of 8 consecutive pixels. The maximum
deviation that can be compensated is -20% of the highest signal level (brightness) of the
line.
Important note:
Depending on the optics and/or illumination used together with the camera, it may not
be possible to fully compensate for shading.
Operating procedure for individual R, G and B channel shadings correction:
1. Before making adjustment, it is required approximately 30 minutes warming up.
2. Make sure the output signal is not saturated (80% of full output is recommended)
3. Set command PGC=2 and SDC=2.
4. Set command SDR to 0 to initiate shading correction.
5. If desired, set command PGR to 0 to activate flat-field (pixel gain) correction to
correct for pixel response non-uniformity.
6. Again set SDR=0 after running the flat-field (pixel gain) correction
(B) Chromatic shading correction (SDR=1)
In this mode, shading correction of R and B signals is referenced to the G signal which is the
reference. When the Green channel detects “undulating” or “parabolic” type shading, R
and B channels are compensated to follow the same curve.
The calculation is based on the average value of 8 consecutive pixels
Important Note:
For this function, no reference value is stored in the camera.
Operating procedure for individual R, G and B channel shadings correction:
1. Before making adjustment, it is required approximately 30 minutes warming up.
2. Make sure the output signal is not saturated (80% of full output is recommended)
3. Set command PGC=2 and SDC=2.
4. Set command SDR to 1 to initiate shading correction.
5. If desired, set command PGR to 0 to activate flat-field (pixel gain) correction to

9 Camera Control Tool for CV-L108CL
From www.jai.com a Camera Control Tool for Windows 2000/XP/Vista can be downloaded.
The control tool contains a camera control program and tools for making your own program.
For the integrator and experienced user, the Camera Control Tool is much more than a program
with a window interface. It also provides an easy and efficient ActiveX interface built for MS
Windows 2000/XP/Vista. The OCX interface has the ability to connect to the camera using the serial
interface of the PC by reading and writing properties for the camera. This integration requires
simple programming skills within Visual Basic, Visual C++ or similar languages in a Microsoft
Windows environment.
CV-L108CL
37
9.1 Control Tool Windows
CV-L108CL
38
9.2 Camera Control Tool Interface
The Camera Control Tool Software is based on a main Tool Bar and a number of associated Tool
Windows. Each button in the Tool Bar pops up a separate Tool Window when pressed. The layout of
the program can be adjusted by arranging the windows the way it is preferred. The program will
store this information and recreate this layout, when the program is restarted.
All Camera Control Tools have a Communication Window and an About Window. The other
window(s) contains camera control commands.
The About window
The about window contains a picture of the camera and
information about the version of the program, Internet
connection to JAI A/S and access to the help
documents.
The List box that contains the help documents will list
all files.
It is possible to download updated operation manuals
from the jai website:
http://www.jai.com
An updated manual can be saved in the folder address
mentioned above .
For newer camera models the About Window also shows
Model Name, camera ID and User ID. It is possible to
edit and save free text in User ID.
At the bottom of the windows (all windows but the Communication Window is a colored bar. The bar
is green when the Camera Control Tool is connected to
a camera and the camera is turned on.
The bar is red when the Camera Control Tool is not
connected to a camera or when the camera is turned off.
The Communication Window
The Communication Window is used to connect the
Camera Control Tool with the JAI camera. Depending on
the camera there are 2 possible ways to communicate
with a JAI camera.
RS-232:
Select the communication port, where the serial cable
is connected from the list box in the „Communication
Port‟ field, or click the „Auto‟ button to search for a
camera on communication port 1 to 16. The camera
control program automatically sends a camera request
on every communication port. The user is prompted to
use a communication port if a camera answers the
request.
RS-232 and Camera Link:
The Communication Window looks a bit different when
it is possible to communicate with the camera using Camera Link and RS-232 com port. The
Communication area contains 2 list boxes now.
CV-L108CL
39
RS-232 communication:
1. Select ‟COM-ports‟ from the ‟CL
Manufacturer/COM-ports‟ list Box.
2. Select the communication port, where the
serial cable is connected to the camera from the ‟Serial Port‟ list box or click the „Auto‟
button to search for a camera on communication port 1 to 16.
The Serial Port list box and the Auto search button are only active when COM-ports is selected.
Camera Link communication:
The „CL Manufacturer/COM-ports‟ list box also
contains DLL file names (or frame grabber names) for
all Camera Link frame grabbers that are installed in
the pc. This is done by using a DLL file called
"clserial.dll" to upload all frame grabber DLLs that are
found in the pc.
Just select the option for the frame grabber that is installed in the pc.
Auto search
Click the auto button to search for a camera on communication ports 1 to 16. The camera control
program automatically sends a camera request on every communication port. The user is prompted
to use a communication port if a camera answers the request.
This button is only used for RS-232 communication.
Off/On-line mode
The Camera Control Tool Application can run Offline (without a camera attached)
and all functions are fully functional in offline mode.
Off line mode is indicated in The Communication Window, where a status field
with graphic and text indicates the on/off-line status.
Changing the selected communication port (from the communication window)
changes the online/off-line status. If a camera is found on the selected communication port the
application runs online otherwise offline.
Changing the settings in the application will automatically update the camera settings when the
application is online.
If the application loses connection with the camera it will automatically go to offline mode and it is
indicated in the communication window.
Synchronize program and camera
The Camera Control software has the ability to synchronize either the camera or
the program. Click Synchronize camera to write all settings from the program to
the camera or click the Synchronize program to load all settings from the
camera to the program.
Files
When clicking the Write to File or Read from File button, the user is prompted for a file using a
standard file dialog. New files are created if they do not already exist.
Files for camera settings have the extension cam. Information about the communication port is not
stored in the files. All settings are automatically sent to the camera when a file has been loaded (if
the camera is online).
CV-L108CL
40
Factory and User Settings
Use the Store button to store the current camera settings into the user settings area in EEPROM.
Current camera settings are not saved when the camera is turned off. To save current camera
settings you have to save them in the available user areas.
Use the Load button to restore previously saved camera settings from either the Factory or the User
EEPROM area.
Write All Camera Data to File.
Click the “Write Camera Data” button to save all camera settings into a
text file. The information that can be saved is:
Model Name, Camera ID, User ID, Firmware Version, Current Settings,
Factory Settings and the available User Areas.
EEPROM Current Area.
Click the „Get Area‟ button to read the power up settings area number.
9.3 Using Camera Control Tool
Here is some practical information about the Camera Control Tool:
1. The Camera Control Tool bar is always on top of other windows.
2. When you minimize the Camera Control Tool bar all open windows will close.
3. It is possible to work with the Camera Control Tool when the camera is online and
when the camera is offline.
4. The newer JAI cameras always start up with the last used user area (but for some old
models it will start up with the last saved user area.)
5. The Camera Control Tool saves the last used settings (not the user area), which don‟t
have to be the same as for the last saved user area.
6. The setup file „CameraName.ini‟ stores all information about camera settings. When
the program is started, the last settings for the program are loaded from the file
„CameraName.ini‟
7. When you turn on the camera and the Camera Control Tool, it is possible that the
Camera Control Tool does not show the actual camera settings (see 4. and 5.).
a. To obtain the camera settings click “Synchronize Program”.
b. To send the settings that are saved in the Camera Control Tool (last used
settings) to the camera click “Synchronize Camera”.
c. To see which area the camera has started up in click “Get Area”.

12 Appendix
12.1 Precautions
Personnel not trained in dealing with similar electronic devices should not service this camera.
The camera contains components sensitive to electrostatic discharge. The handling of these devices
should follow the requirements of electrostatic sensitive components.
Do not attempt to disassemble this camera.
Do not expose this camera to rain or moisture.
Do not face this camera towards the sun, extreme bright light or light reflecting objects.
When this camera is not in use, put the supplied protective cap on the lens mount.
Handle this camera with the maximum care.
Operate this camera only from the type of power source indicated on the camera.
Remove power from the camera when changing switch settings.
12.2 Typical Sensor Characteristics
The image sensors used in the CV-L108CL have been chosen for their superior performance. There
may, however, always be artifacts visible in the scanned image originating from pixel imperfections
in the camera. The Pixel Gain and Pixel Black correction functions will allow the user to compensate
for such artifacts, producing an essentially “flat” image.
12.3. Caution when mounting a lens on the camera
When mounting a lens on the camera dust particles in the air may settle on the surface of the lens
or the image sensor of the camera. It is therefore important to keep the protective caps on the lens
and on the camera until the lens is mounted. Point the lens mount of the camera downward to
prevent dust particles from landing on the optical surfaces of the camera. This work should be done
in a dust free environment. Do not touch any of the optical surfaces of the camera or the lens.
12.4. Exportation
When exporting this product, please follow the export regulation of your own country.
