Follow up of WP6382
I took advantage of the earlier down time to test the HWS stream images script and swapping CLink around. The original set up after Carlos installed the second PCI-e card was HWSY CLink was plugged into the new card and HWSX CLink remained the same (plugged to old card). HWSX streamed live images without problem while HWSY can't get any sensible image at all (see attachment). So I tried a few more configurations:
We have come to the conclusion that the spare card might be busted. The next thing to try is to order a new card and try again. This way we will know for sure that the card actually works. We don't know where the spare card came from and whether or not it has been tested.
Only HWSX code is left running for now.
The cards were all ordered at the same time for aLIGO but were not individually tested.
It's probably the capture card but It might also be the actual PCI slot on the bus. Have you tried swapping the two cards around?
