Image Acquisition Checking The major debug feature is to be able to see if the control tool can take pictures. Once it can, then it is assured that AutoVISION/Visionscape can. To take a picture, click on the “Start Acquisition” button on the menu bar. A window will open up to show the image. Image time stats will show up in the bottom bar. Observe the image. Any ripping in the image is an indication of dropped packets and that packet parameters may have to be adjusted. If the Jumbo Packet setting is correct, then increase to the Interpacket delay. Do this iteratively until the image is solid. Another way to observe this is to go to the Feature Tree Tab.
Scroll down to see the GigE Image Acquisition section. This will show you if packets are being dropped as it is taking pictures. Again, adjust the packet parameters on the camera to keep this from happening. You may also experiment with lowering Interpacket Delay. 6000 is a high default. On a good PC and NIC, this can be lowered to reach the fastest camera rates. The Missing Packet indicator, along with the FPS reading at the bottom of the screen are the guides for this operation. Once you are done tuning these values, they should be copied to the registry so they get set explicitly by Visionscape when new jobs are created.
