Can you describe what you were trying to do, what the hardware is, how it is set up? It is obviously not a GPIB error, don't recall any GPIB enabled cameras, so that means that the error being returned, whatever it is, is being misidentified. We will need more information as to what you were doing when the error occured.

i am trying to do vision aquasition on my webcam.

the only  video mode that labview allow me is 1600x1220 at 5fps.

i need do work with video mode that is 680x480 or so at 30 fps.

so when i select a different video mode, thats the error i get.

Hi,

can anybody help me? (sorry for my bad english)

I have developed acquistion sw based on GC2450C Prosilica-Allied.

The camera acquire an image of about ROI 800x2448 by using an external trigger at 14Hz (generated by an encoder) and extract just 3 lines in the middle of this frame (I am using this camera like a linear camera).

Then, I append these 3 lines contunously until the object is passed completely below my acquisition system.

The ROI so wide is necessary to activate whitebalance - gain in a subregion known as DSP, where GC2450C continuosly performs wbal - gan correction.

After few hours of running (1 - 3 there is no relationship) the IMAQdx grab module give me back a timeout message, like the camera wasn't able to give me any image.

But, if I stop my .vi and run immediately, the program start again without show me any problem.

After few hours again, it stops in timeout mode.

Could it be due to network card? I'm not currently using INTEL PRO1000 but realtek chipset.

If I acquire a ROI of 3 x 2448 and nothing else, the vi run contiuosly with no problems.

Thank you very much for any help could give me!!!
