GIGE image goes black

[bmejoe]

I used to operate a GIGE camera at roughly 500x500 pixels and have decided to expand the amount of pixels we're using.  The new pixel resolution is roughly 2000x2000.  After changing the resolution, an image pops up then it turns black.  I suspect there's some kind of memory issue.  I'm perfectly okay with lowering the frame rate, but when I lower it in MAX it still doesn't work correctly.  Does anyone have any advice?  I'm on 8.5.1 with jumbo frames available at 9 kbytes.

I occasionally get an error code: -1074360317, however, this is only when I use LabVIEW.  In MAX it doesn't show any kind of error code.  Thanks in advance!

Have a look at http://forums.ni.com/t5/Machine-Vision/Can-Session-ID-IMAQdx-be-shared-among-threads-getting-image/m... for a possible solution to the error number.

As far as the black screen goes, you've already got jumbo frames on which would have been my suggestion, so I can't be much help there.

Hi bmejoe,

Here is a Knowledge Base article that should fix your issue regarding the error code in LabVIEW.  As far as the black images go, what is your packet size set to in MAX? Try and set it to 500 or 1000 and see if you still get the same error.  I hope this helps!

Thank you both for your responses.  I already had everything programmed correctly, per what I've seen in the forums and the knowledge bases.  

Dropping the packet size to 576 (the minimum the program will allow me) allows me to increase the pixel resolution to 1500x1500 with a huge drop in the frame rate, however, I still can't go to the maximum resolution without having the image go blank.  Is there maybe a jumbo frame ethernet card I'm unaware of that can go higher than 9k bytes (if that's even the problem)?

Hi bmejoe,

What type of ethernet card do you have?  The most common is the Intel Pro/1000 NIC which supports jumbo frames at 9k bytes (as you mentioned).  This Developer Zone is a great resource for troubleshooting GigE cameras.  Specifically for your application, please go to section 3: The camera can be opened in MAX, but it does not acquire images.  If you do indeed have an Intel Pro/1000 NIC, this will be helpful for installing the high performance driver.  I hope this helps!
