[thinnker]

Hi In my project i need to interface FRAME GRABBER in order to capture the images. I have epiphan VGA2USB frame grabber device. Device doesnt provide labview VI files. I like to know how to interface this device in labview. Thanks In Advance. Regards, Hari

There are no Driver APIs for this device. So, you can't directly use the device with LabVIEW. However, if the manufacturer has provided any .dll for the device, you might be able to control your device using Call Library Function Node in LabVIEW. Otherwise, there is no other way unless you write your own driver.

Have you resolved this issue? I am trying to do the same thing...

Just FYI for anyone trying this, first install the epiphan provided driver. Then you should be able to use the labview example called "grab" it should work fine. Just be sure the 'camera name' is assigned to the correct one. At first my labview program kept grabbing images from the inbuilt webcam, once I changed the camera, the program worked fine with the epiphan capture card. 

Good luck!

I'm in similar situation to capture frames. Would you please share "grab.vi" example...?

Appreciate your response.

Thanks

Hi all,

I'm also trying to use an Epiphan frame grabber (though I'm using the VGA2PCIe so different bus, but same concept).  I don't have the "grab.vi" example either.  Is that something that comes with a toolkit like NI Vision Development Module, or NI Vision Builder for Automated Inspection, or something like that?  I don't have any of these plugins, just plain ole LabVIEW pro. 

Also, I saw a different discussion that said I should be able to see the frame grabber appear as a camera in MAX... no such luck. It does appear in my Windows My Computer window under "Scanners and Cameras" but I don't see anything in either MAX or LabVIEW that makes it clear that I can use this device.  So posting grab.vi would be a good first step.  Any more detailed tips on how to get things working would be another appreciated step.

Thanks,
