Datatraslation's DT-LV link, DT9801

[RobinC]

Hi, guys.  I'm really stuck, if you can help me out that would be great.  The attached upload is the part of the program that I'm not able to figure out.  Basically, I need to take take samples (simultaneous if possible) from 3 different analog input channels on the Datatranslation DT9801 (www.datx.com) and writing to a digital port at the same time.  I will need to graph each of these channels separately and save data so that each channel is separated by columns.  I have viewed all the DT-LV examples, but couldn't find the solution.  My questions are below:

1. Using other DT VIs seems to return many subsystem related error to me.  Therefore, in the diagram, I am using the AI continuous scan, which does give me errors so far.  Is this the correct approach?
2. With the current setup, the resultant Labview measurement file (.lvm file) only gives me 2 pieces of data, one at time 0, another at time = 1, while it really should be taking 1000 data points during this time.  The graphs also don't seems to appear correctly.  What is wrong with my approach?
3. Is there anyway to pre-configure the channels?

Some years ago I used a DT98xx device and had similar problems with
their labview driver. I found some kind of racing conditions errors in
one or some of the driver VIs and fixed them.

Could you share your "repaired vis" with us? I have the same problem. The vis produce a lot of subsystem errors.

Thanks in advance
