NuDAQ PCI-9812 Card isn't working properly!

[kev_joyce]

I have four NuDAQ PCI-9812 Cards plugged into my machine. I am a complete beginner with labview and have only been using it for a couple of days. Using the manual and a couple of flukes, i have written a program that should basically test each port when a simple square wave signal is attached. I find that it works for the first channel on the first card but gives me garbled signals or no the program doesn't execute on the other ports on all cards. I know that all the cards work because a visual basic test program was provided and they all work with that!!

If anyone can help me i would be really grateful!!

Attached is a copy of my test program.

Cheers

Kev

Your challenge is with the LabVIEW library for the PCI-9812 board. This library would appear to be the one with the challenge. Have you contacted the author of the 9812 library? Also please note, if you would like to upgrade to a National Instruments data acquisition board, the NI boards come with excellent support complete driver scaling data to engineering units for you, and may examples that work out of the box. Our sales teams may even be able to offer an upgrade discount.
