Hi ChristianEC,
unfortunately there will be no chance to get the information that you want directly like the serial numbers of your cards.
There might be a chance to get the information via ActiveX and some MAX properties. The idea is to read the information from MAX, but unfortunately I didn't have the time to check this in detail.
Another solution could be to "ping" the PXI-systems from your host computer and to get the information as a result. For sure, this method only works, if your PXI-systems have static IP-adresses.
