GigE camera Lost Packets - Jumbo Frame

[gopinathbb]

Using GigE camera own software I acquired video without loss of packet. But using Vision Acquisition in LabVIEW I can't get continuous video data. And, Unable to increase the Byte rate beyond 1500 bytes. I am using LabVIEW on windows 11 pc

I won't be able to give you a full solution because I don't work with GigE cameras anymore, but I had similar issues at my previous job, and I remember it being very frustrating at first.

What you have to realize is that your camera software might automatically adjust settings to optimize the acquisition, while Labview/IMAQ doesn't. IIRC you want to check settings such as the frame rate, bandwidth and maybe others in the camera OEM software, and then set the same values in NI MAX (or programmatically if you need to adjust them).

Best of luck.

Why do you believe this is an issue with jumbo frames?

Not every camera supports jumbo frames.

Start NI MAX, open your camera and check if grab displays images. If not, check the camera parameters in the list.

Possible reasons (not complete): Camera is set to incompatible color mode or trigger mode is activated.

Is this just image acquisition or image acquisition + image processing + image save?

Image acquisition and image saving

Hi Bill,

    I don't think this is due to jumbo. Coz if it is jumbo then the OEM software doesn't stream video continuously.

If this is the case, is saving in a separated loop?  Because saving is slow.  Please post your VI.

[gopinathbb]

I am not even creating VI. Just using NI-MAX to grab the stream.

Is your camera 16 bit gray or 8 bit?

Have you setup the Jumbo packet?

NI MAX might not be the fastest way, LabVIEW might be faster if you do it right.
