The camera name is partly hidden in the Experiment Settings
For example:
In the Windows Control Panel, choose Display and reduce the text size, for example select 100%.
I cannot see the camera image when I click on the Camera icon in the Experiment Settings
1.Make sure that pylon Viewer is closed.
2.Make sure that the camera(s) is connected to the PC and powered prior to opening EthoVision XT.
3.Make sure that the aperture of the lens is fully open (lens ring all the way to Open or O).
4.Make sure the correct camera is selected in the Video Source list of the Experiment Settings. For example: Basler GenICam [Basler acA1300-60].
5.Make sure that the correct camera driver version 7.5.0 is installed. To find the version number, In the Windows Control Panel choose Programs and Features and locate the pylon Camera Software Suite.
6.Check the IP addresses of the Ethernet board ports and the cameras. See Assign IP addresses
When I click on the camera icon in the Experiment Settings, the Video Settings box says “No frames available”
1.When using Windows 10: make sure you installed the camera driver from the installation files. If you installed it from an older installation disk, you could have installed an older driver (for example 4.2.1) which doesn’t support Windows 10. For the driver version that applies to your cameras, check the table in Cameras supported by EthoVision XT
2.If you changed the settings in pylon Viewer, check in that software under Acquisition Controls that the Trigger mode is set to Off.
3.Other causes are possible like installing Windows 10 on an older PC which isn’t compatible with Windows 10.
4.If none of these examples fit your situation, contact the Noldus Support for further assistance. Please also Make a PC report for Supports.
There is no video camera listed in the Experiment Settings
▪Make sure that the IP addresses are assigned to all cameras and ports in the Ethernet board, based on this topic: Assign IP addresses
▪Check in the Windows Control Panel that the drivers for the camera are installed.
▪Check the driver version. If the driver version differs from that reported in the table (see Cameras supported by EthoVision XT), uninstall the driver from the Control Panel. Install the correct driver, which you can find on the Noldus web site.
important Always re-install the camera drivers from the EthoVision XT setup file, using the Modify option. If you need to install the Basler camera driver software from the original installation file Basler_pylon_[version number].exe, do the following:
▪Log in to my.noldus.com. Choose Downloads > EthoVision XT > Drivers and Tools. Download Basler Camera Driver - Noldus - [version number]. Extract its content and copy everything to the local disk.
▪Double-click the file Basler_pylon_[version number].exe. Accept the Terms and Conditions, then click Next.
▪Under Profiles, select Custom and click Next.
▪Under Features, choose GigE Camera Support for GigE Vision cameras, or USB Camera Support for USB 3.0 cameras. Make sure to select pylon Viewer and DirectShow Support.
▪Complete the installation.
One or more cameras are not listed in the Experiment Settings
▪Check that you selected the correct number of cameras.
▪Check that all cameras are connected and powered up. For digital cameras: close EthoVision XT and start pylon IP Configurator. There you should see which cameras are connected.
▪Make sure that the IP addresses are assigned to all cameras and ports in the Ethernet board, based on this topic: Assign IP addresses
▪Check whether that camera is already selected in a different input. For example you do not see a camera for input 4 because that camera was already selected for input 1.
▪It may be that after adjusting the settings for the first camera, those settings are no longer compatible with those still applied to the other cameras.
For example, suppose you select Binning for the first camera, then you decide to de-select it. When you return to the camera list, Binning is still selected for the remaining cameras. This makes the camera views of the other camera incompatible with that of the first one. The result is that the remaining cameras are removed from the list. To solve this, select a new camera from the list at the top, and clear the Binning option also for that camera. Click OK, and do the same for the remaining cameras.
The settings for color space are not available
I have a color camera Basler AcA1920-40gc. When choosing the color space, the settings for the BYRG are not available.
Solution:
1.Select BYRG as color space.
2.Disconnect the camera, so it does not receive power.
3.Reconnect the camera.
4.Fine-tune the camera setup leaving the color space to BYRG.
I cannot select a specific combination of frame rate and color space
This happens because some values of video frame rate and color space are not compatible in some cameras. Those frame rate * color space combinations have been removed in the software.
EthoVision XT stops working when two or more digital cameras are connected
The problem occurs when the video resolution does match the values accepted by the software. Select for example 800 x 600, not 640x 426. See the tables in Cameras supported by EthoVision XT

▪Adjust camera settings in EthoVision XT
I cannot select a high frame rate
For example, in the EthoVision XT Experiment Settings, when I set the resolution to something in the range of 1280x960, the maximum attainable frame rate is for example 7.5 frames per second.
1.Check that the Exposure time setting isn’t too high. See Adjust camera settings in EthoVision XT > Camera/General tab
2.Make sure that the Power Injector is in fact a 1GB Power Injector.
3.Make sure that the network card is in fact a 1GB network card. If that is the case, check that it is set to Auto-negotiate. If it is, then the network card either needs a driver update or is defective.
4.Check the cables. Cheap, incorrect or defective Ethernet cables can also reduce the frame rate.
5.The PC may have insufficient resources, for example only has an on-board video card. Please contact the Noldus Support and Make a PC report for Support.
I notice that video frames are dropped. Reducing Exposure time did not help.
See this page and check that the camera settings match those of the Ethernet board:
After selecting the first GigE camera in Experiment Settings, when I select the second camera, EthoVision crashes
In the Experiment Settings, next to each video source, select a standard resolution like 640x480. Avoid resolutions like 640x426.
When using multiple GigE cameras, if one of the camera signals is lost, the order of the cameras in EthoVision XT scrambles
1.Always plug the cameras into the same ports. Label the ports and camera cables if needed to keep things in order.
2.Restore the camera signal.
3.In EthoVision XT, choose Setup > Acquisition, then choose Setup > Experiment Settings, and then go back to Acquisition. The camera order should now be restored to what you originally setup when first setting up this experiment. Despite the visual swapping of the cameras listed in Source table (via Experiment Settings), the order of the cameras should still load in the correct order matching the arenas.
Error message “Device unplugged”
Check first the cable connections between cameras and PC.
Check the video resolution in the Experiment Settings screen. Probably the resolution of resulting merged view is too large. Reduce the resolution in such a way it is compatible with the software.
▪For eight cameras, 2560 x 960.
▪For sixteen cameras, 2560 x 1920.
