Hi Katie
I asume that you're trying to use the DAQ Assistant, isn't it? The problem is that your board is not supported by NI-DAQmx, so you can't use the DAQ Assistant to program it. You must use the Traditional NI-DAQ VI's to program your board. If you open MAX, then you'll see your board "only" under "Traditional NI-DAQ Devices" and not under "NI-DAQmx devices".
Open the "Example Finder" in LV and browse to Hardware Input and Output>>Traditional DAQ>>Counters>>NI-TIO. You'll find some examples for the 6602 board.
Hope this helps.
Luca
