I was hoping that some kind soul would grace me with some in- struction or some pointers to links or something.
Problem: I'm running an SCXI chassis with multiple(5) cards in it. Two of the cards are 1120's. One of 1120 modules is in slot one and the other is in slot five. I need to be able to read the voltages from these analog cards simultaneously.
Currently I have a VI with two parallel loops each doing a read on one of the cards. Leading into each loop I have a AI config function and an AI start function. It doesn't work something about resource in use is the problem. What I think the problem is is that there should be a group(which I hope someone will explain what this is) that both AI modules are in and then treat the m as one "meta-module"?
Am I totally off base?
Any help or suggestions will be greatly appreciated! --

Check your SCXI chassis' user manual. I believe that there is a heirarchy of those cards, and that the 1120 is near the bottom. This means that it can't be in clot one, one of the others must be ahead of it. I honestly don't recall the details, but I'm pretty certain that you can't plug the cable into th e back of it - it must go into the back of one of your other 3 cards.
