Image Capture Speed

I am capturing images from a conveyor using a photo switch wired directly to the camera.  The problem is the image capture rate is not fast enough.  The attached basic capture logic is running at about 350 ms but I am only getting every second or third image.  I am using the following equipment:

-Prosilica GC750 GigE camera.

-SMC 8508T Switch.

-Intel PCI Pro/1000 Card.

-Labview 8.6

-Dell Inspiron 530 with Intel Core 2 processor Q6600, 2 Gigs Ram.

When I run Measurement & Automation Pro "Grab" every trigger is captured.   I have configured the network interface for Jumbo frames.  Is there something I have forgotten or is this possibly the limitation of the equipment.

Thanks for the help,

Doug

Hi,

 

open MAX and in the ethernet card of the camera configure the packet size to 9000 (same size as intel card JFrames).

Are you getting every image if using MAX, I am a bit confused from your post.

Try to use this VI, read help to know how to configure buffers.

I allways use this kind of reading mechanism to get the pictures.

Check your network load and CPU load when grabbing.

 

How do you know you are getting every third frame ?

Hi,

I had already set the packet size for 9000, but I will try this approach.  Thanks for the reply.
