Hi V.GRAF, The DAQ 6025E is a special card in terms of digital I/O. This is because it has two different semiconductor chips handling the digital. It has the DAQ-STC chip handling the first port of 8 bits (Port 0). It then has the 8255 chip handling the 3 other ports.
In general, you should be able to use any of the DAQmx programs for digital with this card. However, you have to make sure that you are configuring the entire port at the beginning of your program. This is because if you reconfigure any of the 3 ports on the 8255 PPI chip, it will reset the port. So my suggestion is to not use "line" configuring but instead use "port" configuring. Here are a couple Knowledge Bases that discuss the issue.

Have a good day. Ron Applications Engineering National Instruments
