The Camera Name Is Partly Hidden in the Experiment Settings

In the Windows Control Panel, choose Display and reduce the text size, for example select 100%.

Cannot See the Camera Image 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.

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 does not 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, such as installing Windows 10 on an older PC which is not compatible with Windows 10.
4. If none of these examples fit your situation, contact Noldus Support for further assistance. Please also make a PC report for Support.

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. See 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 and install the correct driver.

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. See Assign IP Addresses.
• Check whether that camera is already selected in a different input. For example, you may 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 cameras 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 for that camera. Click OK, and do the same for the remaining cameras.

The Settings for Color Space Are Not Available

For a color camera such as the Basler AcA1920-40gc, when choosing the color space, the settings for BYRG may not be available.

Solution:

1. Select BYRG as the 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 set to BYRG.

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 and 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 not match the values accepted by the software. Select for example 800x600, not 640x426. See the tables in Cameras Supported by EthoVision XT.

Cannot Select a High Frame Rate

For example, in the EthoVision XT Experiment Settings, when the resolution is set to a range of 1280x960, the maximum attainable frame rate may be as low as 7.5 frames per second.

1. Check that the Exposure Time setting is not 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 an on-board video card. Please contact Noldus Support and make a PC report for Support.

Video Frames Are Dropped and Reducing Exposure Time Did Not Help

Check that the camera settings match those of the Ethernet board by referring to the following resource:

EthoVision Crashes When Selecting the Second GigE Camera

In the Experiment Settings, next to each video source, select a standard resolution such as 640x480. Avoid non-standard resolutions such as 640x426.
