Hi,
I'm having some trouble with my GigE camera (Allied Vision Prosilica GT1920) connected to the computer via a PoE injector. I have been using this camera for several years, and it ran perfectly until 2 days ago. Every time I start to grab image either in my LabView vi or NI MAX, it can take image without any issue for a random amount of time (sometime a few seconds, sometimes a few minutes), after that I start to see a flickering garbled image and eventually a black image. At the same time the ethernet receive of the computer will decrease from 700Mbps to 40Mbps. If I use the Vimba Viewer to grab images, The receive fps and the display fps can sometimes become super lower (e.g. 0.3Hz), while the camera fps is normal (16Hz). Sometimes the frame number may get stuck when the three fps numbers are all 16Hz. Btw, the computer CPU and RAM looks normal when this happens.
The interesting part is, every time I stop the image acquiring and then restart, it works properly again (at least for a while).
I have checked the wiring and replaced two ethernet cables (camera to PoE injector and PoE injector to computer). Wiring shouldn't be the problem.
Can anyone help me out? I welcome any suggestions.
