How to identify digital or analog frame grabber installed in PC by NI software

[yu_guo]

Hi,

since NI will not support analog frame grabber so we have plan to use digital frame grabber PCI-8252 to replace analog

one PCI-1405,I have a question, our application software is Labview 8.6 based and the software will be modified since digital frame grabber used, but due to analog one PCI1405 and digital one PCI-8252 may be used in different machines, we'd like the application software can intelligently to identify analog frame grabber or digital frame grabber is installed in an individual PC, from the perspective of software development, how does the program to know digital one or analog one is used, as you know, image acquisition by using digital or analog frame grabber is different, but we need the program to identify which one is installed and therefore respective processing is adopted. anyone has idea about it or is there any similar threads in the board can share with us?

Thanks!

Hi Yu Guo,

As you know, the driver used won't be the same if you use analog or digital board. For the 1405, you use IMAQ driver, but with 8252, you will need IMAQdx. 

So, to identify the board installed on your PC, try to open your camera with either IMAQ init.vi or IMAQdx Open Camera.vi. One of them will return an error and the other won't.

Hope this helps
