We need to use the PFI0 port on the PCI-6133 as a trigger. But doing this we had some problems (mainly because our trigger is a spike-form, not really digital). So here my questions
- Why does the PFI0 port stay on approx 5V when not connected (this interferes with the height off our "spike-trigger'
- It seems weird but, is it possible that the PFI0 port inverses signals.
A second (small) problem we saw, is the fact that every Analog port on the card, keeps rising in tension when it is not connected. Why is this?
