I have a Euresys Grablink frame grabber , using camera link connectivity for a mega pixel ccd camera and need to use it with labview. How can I communicate with the 3rd party frame grabber via labview?
In order to communicate with a third party framegrabber, you'll need to use the Call Library Function Node found in the Functions>>Advanced palette. From here you'll have access to the dll supplied by the Euresys framgrabber and can call the necessary functions to acquire images. Take a look at chapter 2 in the Using External Code in LabVIEW manual: http://digital.ni.com/manuals.nsf/webAdvsearch/8D930295FFBF9F7686256D2C00624728?OpenDocument&vid=niwc&node=132100_US
If you need more processing abilities, such as pattern matching and edge detection, you may want to look into purchasing the IMAQ Vision add-on software: http://sine.ni.com/apps/we/nioc.vp?cid=2881〈=US

According to Euresys they do have some LabVIEW VIs to do that. Don;t know how well wirtten they are but check it out
Like Julie mentioned above, it is necessary to make function calls to the Euresys frame grabber dll that they provide. It seems Rolf knows of some pre-written LV VIs that are provided by Euresys. You will need to contact them in order to acquire these.
I also use a Euresys Grablink framegrabber with a 1024 pixels AViiVA linescan camera from Atmel. So far I manage to grab and save images of predefined length in Encoder mode (line trigger with encoder on production line). The only way I found to view the images is through a EBW8Image control of Euresys (eVision.ocx). I prefer to use a IMAQ Image Display Control but that's not possible because the SetCluster method of the ECamera activeX object accept only Euresys controls :(( too bad!! So, did any one of you manage to view Euresys Grablink images in a IMAQ Image Display Control or not?
Another problem I have is to start and stop saving images to harddisk. What I want to do is give the operator the ability to start and stop grabbing and saving images. Start and stop grabbing is done using the ChannelState parameter of the grabber; no problems. Start saving is done using a Reg Event Callback when the EBW8Image control refreshed but I don't know how to unregister my callback event. Anyone who knows?
Unfortuantely, I really do not know anything about Euresys framegrabbers. On the other hand, I felt that I should at least poke my head in here and say that I've done the same thing using NI Framegrabber's and have been able to write my code in less than 15 minutes. That said, I understand that changing hardware isn't always an option. I wish you the best of luck!
