1. System Precautions and Cleaning
Precautions
Read these precautions and this manual carefully before using the camera.
Confirm that the cam era ‘s p ackagin g is und am aged b efore op ening it. If th e packaging is d am aged p lease
contact the related logistics personnel.
Do not open the housing of the camera. The warranty is voided if the housing is opened.
Keep th e camera‘s fron t p late 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 elect rostatic charging, violent vibration, and excess moisture.
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 o f 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. Further cleaning instructions are below.
Though this camera supports hot plugging, it is recom mended that you power down and disconnect power to the camera before you add or replace system components.
Electrostatic Discharge and the CMOS Sensor
Image sensors and the camera bodies housing are susceptible to damage from electrostatic discharge (ESD). Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the window. The charge norm ally dissipates within 24 h ours and the sensor returns to
normal operation.

Camera Link Drive Capability
The camera link cable drive capability on LA-4K/ 2K cameras has been improved to reach up to 10 meters. This capability has been tested using a number of frame grabbers (listed in the table below) and was tested using standard Cam era Link cables. The cable length drive achieved on the various frame grabbers is as follows:
Table 7: Cable Length and Frame Grabber Pairings
Input Signals, Camera Link
The camera accepts control inputs through the Camera Link SDR26F connector. The camera ships in internal sync, and internally programmed integration.
EXSYNC (Line Readout Trigger)
Line rate can be set internally using the GenICam features. The external control signal EXSYNC is optional and enabled through the user interface. This camera uses the falling edge of EXSYNC to trigger pixel readout.
The EXSYNC signal tells the camera when to integrate and readout the image. It can be either an internally generated signal by the camera, or it can be supplied externally via the serial interface. Depending upon the mode of op eration the high time of the EXSYNC signal can represent the integration period.
Note: Th e EXSYNC sig n al is m easu red at CC1 and w ill g ive a ―tru e‖ m easu rem en t (i.e. within th e
measurement resolution of 25 ns) even though the camera will only trigger at a maximum of 80 kHz.
Output Signals, Camera Link Clocking Signals
These signals indicate when data is valid, allowing you to clock the data from the camera to your acquisition system. These signals are part of the Camera Link configuration and you should refer to the Camera Link Implementation Road Map, available at our Knowledge Center, for the standard location of these signals.

Power Connector
WARNING: It is extremely important that you apply the appropriate voltages to your camera. Incorrect voltages may damage the camera. Input voltage requirement: +5 VDC to +24 VDC, 1 Amp. Before connecting power to the camera, test all power supplies.
Figure 6: 6-pin Hirose Circular Male Power Plug—Power Connector
Table 8. Power Plug Pinout
The camera requires a single voltage input +5 VDC to +24 VDC. The camera meets all performance specifications using standard switching power supplies, although well-regulated linear supplies provide optimum performance.
WARNING: When setting up the camera’s power supplies follow these guidelines:
Apply the appropriate voltages. Protect the camera with a 2 amp slow-blow fuse between the power supply and the camera. Do not use the shield on a multi-conductor cable for ground. Keep leads as short as possible in order to reduce voltage drop. Use high-quality supplies in order to minimize noise.
Note: If your power supply does not meet these requirements, then the camera performance specifications are not
guaranteed.
PoCL Power Over Camera Link
The Linea 2K and 4K Camera Link cameras are PoCL compatible, but 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 by 0.35 W, 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.
LEDs
The camera is equipped with an LED on the back to display the operational status of the camera. The table below summarizes the operating states of the camera and the corresponding LED states. When more than one condition is active, the LED indicates the condition with the highest priority.
Step 3. Establish Communication with the Camera
Power on the camera
Turn on the camera‘s power supply. You may have to wait while the camera readies itself for operation. The camera must boot fully before it will be recognized by the GUI—the LED shines green once the camera is ready.
Connect to the frame grabber
1. Start Sapera CamExpert (or equivalent Camera Link compliant interface) by double clicking the
desktop icon created during the softw are installation.
2. CamExpert will search for installed Sapera devices. In the Devices list area on the left side, the
connected frame grabber will be shown.
3. Select the frame grabber device by clicking on the name.
Note: The first time you set up the camera you will need to establish a communication link between the camera and frame grabber.
Connect to the camera
1. Start a new Sapera CamExpert application (or equivalent Camera Link compliant interface) by
double clicking the desktop icon created during the software installation.
2. In the Devices list area on the left side, select the COM port below the Camera Link label.
Figure 7. CamExpert GUI showing connected camera
Check LED Status
If the camera is operating correctly at this point, the diagnostic LED will shine green.
Software Interface
All the camera features can be controlled through the CamExpert interface. For example, under the Camera Control menu in the camera window you can control the line rate and exposure times.
A note on the CamExpert examples shown here: The examples shown for illustrative purposes and may
not entirely reflect the features and parameters available from the camera model used in your
application.
At this p oin t you r h ost an d cam era sy stem shou ld be setup and you can verify th e cam er a‘s op eration by
retr ieving a test p attern and settin g the camera‘s trig ger and exp osu re time.
Using Sapera CamExpert with Linea Cameras
CamExpert is the camera interfacing tool supported by the Sapera library. When used with a Linea camera, CamExpert allows a user to test all camera operating modes. Additionally CamExpert saves the camera user settings configuration to the camera or saves multiple configurations as individual camera parameter files on the host system (*.ccf). Cam Expert can also b e used to u pgrad e the cam era‘s so ftw are.
An important component of CamExpert is its live acquisition display window which allows immediate verification of timing or control parameters without the need to run a separate acquisition program.
For context sensitive help, click on the button then click on a camera configuration parameter. A short description of the configuration parameter will be shown in a popup. Click on the button to
open the help file for more descriptive information on CamExpert.
The central section of CamExpert provides access to the camera features and parameters. Note: The availability of the features is dependent on the CamExpert user setting.
CamExpert Panes
Figure 8. CamExpert’s Camera Control Window
The CamExpert application uses panes to simplify choosing and configuring camera files or acquisition parameters for the installed device. Device Selector pane: View and select from any installed Sapera acquisition device. Once a device is
selected CamExpert will only present acquisition 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 fram e acquisition display. Frame buffer parameters are shown
in an information bar above the image window.
Control Buttons: The Display pane includes CamExpert control buttons. These are:
Acquisition control button:
Click once to start live grab, click again to stop. Single frame grab:
Click to acquire one frame from device.
Trigger button: With the I/ O control parameters set to Trigger Enabled, click to send a single trigger command.
CamExpert display controls: (these do not modify the frame buffer d ata) Stretch image to fit, set image display to original size, or zoom the image to virtually any size and ratio.
Histogram / Profile tool: Select to view a histogram or line/ column profile during live acquisition or in a still image.
Output Message pane: Displays messages from CamExpert or the device driver.
At this point you are ready to start operating the camera in order to acquire images, set camera functions, and save settings.
4. Camera Operation
Factory Settings
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 and vertical binning Offset 0, Gain 1x
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, etc. are read to uniquely identify the connected device.
The camera information parameters are grouped together as members of the Camera Information set.

Verify Temperature and Voltage
To determine the voltage and temperature at the camera, use the Refresh Voltage and Refresh Temperature features found in the Camera Information set.
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. Once you have diagnosed and remedied the issue use the reset camera function.
Note: The voltage displayed is the cam era‘s input voltage. The voltage measurement feature of the camera provides results within 1% of the actual voltage. The measurement can be used to set the applied voltage to the camera.
Saving and Restoring Camera Settings
The parameters used to select, load and save user sets are grouped together under the Camera Information set of features. There are 8 user sets available and one factory set.
Description of the Camera Settings
The camera operates in one of four settings:
1. Current operation with active settings.
2. User setting.
3. Factory setting (read-only).
4. Default setting.
The settings active during the current operation can be saved (thereby becoming the user setting) using the User Set Save parameter. A previously saved user setting (User Set 1 to 8) or the factory settings can be restored using the User Set Selector and User Set Load parameters.
Either the Factory or one of the User settings can be saved as the Default Setting by selecting the set in the User Set Default Selector. The chosen set automatically saves as the default setting and is the set loaded when the camera is reset or powered up.
