why does the counter work in MAX, but not Labview?

[dav2010]

Please help, I have been away from Labview for over 3 months, and I am quite rusty....

Last year, I successfully configured NI9401 to measure period (seconds) by counting the rising edges of my sensor signal.  Since then, I have aquired a new PC, and loaded all my software into it, including the Labview VI's that successfully worked on the old computer.

I can see the digital signal using MAX and the test panel for the NI9401, so, I know my wiring and my TTL signal is OK, but, when I try to run the attached VI, nothing happens except the error below..  How do I tell this VI to look for the signal on MOD3/CTR0 and channel 14?

Thanks. I am sure it is a small adjustment...this worked fine a few months ago...not sure what is wrong now.

Thanks,

Dave

OK, now.  Resolved the issue. The vi is fine, but, some shaky wires were identified...worked in MAX but not in the vi.  Now that the connections have been tightened up, it works for both.  Sorry for the inconvenience.
