Supported Industry Standards
GenICam™
Linea cameras are GenICam™ compliant. They implement a superset of the GenICam™ Standard
Features Naming Convention specification V1.5.
This description takes the form of an XML device description file respecting the syntax defined by
the GenApi module of the GenICam™ specification. The camera uses the GenICam™ Generic
Control Protocol (GenCP V1.0) to communicate over the Camera Link serial port.
For more information see www.genicam.org
Teledyne DALSA recommends using Sapera CamExpert as your Camera Link compliant camera
interface application. CamExpert is the camera interfacing tool supported by the Sapera library and
comes bundled with SaperaLT. Using CamExpert is the simplest and quickest way to send
commands to and receive information from the camera.
Sapera uses the GenICam™ Generic Control Protocol (GenCP V1.0 ) to communicate with the
camera over the Camera Link serial port. When communications ar e first estab lished , Sapera
downloads the GenICam™ XML Description file. This file details how to access and control the
camera.
.
ASCII Commands
As an alternative to the CamExpert (or equivalent) GUI, you can communicate with this camera
using ASCII-based commands. Using a terminal emulating program, establish a serial port
connection with the c amera.

System Precautions and Cleaning
Precautions
Read these precautions and this manual before using the camera.
Do not open the housing of the camera. The warrant y is voided if the housing is
opened.
• Confirm that the camera’s packaging is undamaged before opening it. If the packaging is
damaged please contact the related logistics pers onnel.
• Keep the camera’s front plate temperature in a range of 0 °C to 65 °C during operation.
• Do not operate the camera in the vicinity of strong electromagnetic fields. In addition, avoid
electrostatic charging, violent vibration, and excess moisture.
• Though this camera supports hot plugging, it is recommended that you power down and
disconnect power to the camera before you add or replace system components.
Cleaning the Device
To clean the device, avoid electrostatic charging by using a dry, clean absorbent cotton cloth
dampened with a small quantity of pure alcohol. Do not use methylated alcohol.
To clean the surface of the camera housing, use a soft, dry cloth. To remove severe stains use a
soft cloth dampened with a small quantity of neutral detergent and then wipe dry. Do not use
volatile solvents such as benzene and thinners, as they can damage the surface finish.
Electrostatic Discharge and the CMOS Sensor
Image sensors and the camera bodies housing are susce ptible to damage from electrostatic
discharge (ESD). Electrostatic charge introduced to the sensor window surface can induce charge
buildup on the underside of the window. If this occurs , the charge normally dissipates within 24
hours and the sensor returns to normal operation.
Recommended System Requirements
To achieve best system performance, the following minimum requirements are recommended:
• High bandwidth frame grabber. For example, Teledyne DALSA Xtium-CL series frame
grabbers: http://www.teledynedalsa.com/imaging/products/fg/#digital-cameralink
• Operating systems: Refer to frame grabber documentation for supported platforms.

performance specifications are not guaranteed.
Power over Camera Link
The Linea 2k and 4k Camera Link cameras are Power over Camera Link (PoCL) compatible*, but
are not compliant with the full PoCL specification as their operation is dependent on the frame
grabber used. These cameras exceed the 4 W PoCL power specification, but some frame grabbers,
such as the Xtium frame grabber from Teledyne Dalsa, are able to supply sufficient power for the
camera’s operation.
PoCL can be enabled from within CamExpert. Be sure to connect the power supply to the Xtium
frame gabber in the PC.
PoCL power can only be supplied through the Data 1 (base) camera link port.
* The 8K and 16K models do not support PoCL.
Camera Status LED

device is selected, CamExpert will only present parameters applicable to that device. Optionally
select a camera file included with the Sapera installation or saved by the user.
• Parameters pane: Allows viewing or changing all acquisition parameters supported by the
acquisition device. CamExpert displays parameters only if those parameters are supported by
the installed device. This avoids confusion by eliminating parameter choices when they do not
apply to the hardware in use.
• Display pane: Provides a live or single frame acquisition display. Frame buffer parameters are

CamExpert View Parameters O p tion
All camera features have a Visibility attribute which defines its requirement or complexity. The
states vary from Beginner (features required for basic operation of the device) to Guru (optional
features required only for complex operations).
CamExpert presents camera features based on their visibility attribute. CamExpert provides quick
Visibility level selection via controls below each Category Parameter list [ << Less More >> ]. The
user can also choose the Visibility level from the View ∙ Parameters Options menu.

Camera Operation
The following sections describe typical operations performed with the camera. The descriptions rely
on the feature-based Camera Link GenCP protocol, using the Sapera CamExpert application. If you
are using a different application, the display configuration will differ but the category, parameter
(feature) names and possible values remain the same. References to related ASCII commands are
provided.
Factory Settings
The camera has been calibrated and configured at the factory to be ready for operation when first
powered up. The camera ships and powers up for the first time with the following factory settings:
• Camera Link Full, 8 bit pixels
• Internal trigger, line rate 10 kHz
• Internal exposure control, exposure time 50 µs
• 1x horizontal an d ver tical binning
• Offset 0, Gain 1x (lowest value)
• Flat field calibration is not active as this feature is dependent on your light source and lens.

Typical Setup and Evaluation
Optical Configuration
Typically, the first thing you want to do is to evaluate the camera’s image quality under operating
conditions similar to those that you are likely to use in your application. To do this, take the
following steps:
• The illumination, lens magnification, and focus should be set up as per you applicat ion .
• Getting the magnification right is best accomplished by setting the object-to-sensor
distance. Use the formula lens focal length x (2 + 1/magnification + magnification) to
calculate this distance. Magnificat ion equ als the sensor pixel size (7.04 µm or 3.52 µm ) /
(your object pixel size in µm).
• The approximate position of the sensor is at the first groove on the side of the camera case
from the front face of the camera.
Camera Timing & Control
It is easiest and quickest to evaluate the camera using the internal timing setups for line rate and
exposure time. The camera starts up in the default configuration of camera link full, 10 kHz line
rate and 50 µsec exposure time.
• If this line rate is too slow fo r your application, you will get a compressed image in the scan
direction. To increase the line rate, use the Internal Line Rate parameter in the Camera
Control category.
• Adjust the exposure time; refer to the Exposure Controls section.
• Set your camera direction: refer to the Pixel Readout Direction (Mirroring Mode) section.
Acquiring an Image
You can now begin imaging . Unless you have an application employing lots of light, the image is
likely to be too dark.
• Use the system gain to adjust the camera output to achieve the desired response. The
system gain range is from 1x to 10x. Refer to the Gain and Black Level (Offset) section.
• Once you have a suitable response, you can now focus the lens.
• The image may be darker at the edges due to lens vignetting, but this will be improved once
the camera is calibrated.
• Calibration is performed using a white reference where your object is normally located.
Refer to the Calibrating the Camera section. When calibrated, you should see an image from
the camera that is flat field corrected with the lens at the target level you set.
You are now ready to evaluate the image quality of the Linea camera under your operating
conditions.

Check Camera and Sensor Information
Camera and sensor information can be retrieved via a controlling application—for example, the
CamExpert GUI shown in the following examples. Parameters such as camera model, firmware
version, sensor characteristics, and so forth, are read to uniquely identify the connected device.
The Camera Information category groups these parameters.
Verify Temperature and Voltage
To determine the voltage and temperature at the camera, use the Refresh Voltage and Refresh
Temperature features.
The temperature returned is the internal temperature in degrees Celsius. For proper operation this
value should not exceed 80 °C. If the camera exceeds the designated temperature it will stop
imaging and the LED will turn red. After you have diagnosed and remedied the issue use the
Restart Camera function.
The parameters used to select, load and save user sets are grouped together under the Camera
Information category. There are 8 user sets available and one factory set.

Camera Config uration Selection Dialog
CamExpert provides a dialog box which combines the features to select the camera power up state
and for the user to save or load a camera state from Linea CL memory.
Camera Power-up Configuration
Either the Factory or one of the User Settings can be used as the default setting and is the set
loaded when the camera is reset of powered up.
The first drop list selects the camera configuration state to load on power-up (see feature
UserSetDefaultSelector). The user chooses from one factory data set or one of 8 possible user
saved states.
User Set Configuration Mana g em en t
The user setting is the saved set of camera configurations that you can customize, resave, and
restore. By default the user settings are shipped with the same settings as the factory set.
The second drop list allows the user to change the camera configuration anytime after a power-up
(see feature UserSetSelector). To reset the camera to the factory configuration, select Factory
Setting and click Load. To save a current camera configuration, select from User Set 1 through
User Set 8, and click Save. Select a saved user set and click Load to restore a saved configuration.
Active Settings for Current Operation
The active setting for the current operation is the set of configurations that are active while the
camera is currently running, including all unsaved changes you have made to the settings before
saving them.
These active settings are stored in the camera’s volatile memory and will be lost and cannot be
restored if the camera resets, is powered down, or loses power.
To save these settings for reuse the next time you power up or reset the camera, or to protect
against losing them in the case of power loss, you must save the current settings. Once saved, the
current settings become the selected User Set.

The command User Set Save saves the current settings to non-volatile memory as a Use r Set.
The camera automatically restores the last saved user settings when it powers up.
To restore the last saved user settings, select the User Set parameter you want to restore and
then select the User Set Load parameter.
Factory Settings
The factory setting is the camera settings that were shipped with the camera and which loaded
during the camera’s first power-up. To load or restore the original factory settings, at any time,
select the Factory Setting parameter and then select the User Set Load parameter.
