Hi Mosgaard,
I have replied your thread in Labview forum, but please only create one thread pr. issue in the furture. It makes our job much easier

You question about the PCI-6534 should be answered in this forum(Digital I/O), however I have already replied your thread in Labview forum, when I found this thread. So let's keep tracking the thread in the Labview forum this time around.
Best Regards!
