NI 9403: Digital input.

[dist1988]

Hello!

I am new at communicating CRIO 9073,C-series modules and LabVIEW. I found an example of digital input for NI 9403 in LabVIEW help and tryied to make it run. When I press RUN button, my project compiles and starting to work, but when I connect each channel ( DI0, DI1, DI2,DI3 pins) to COM channel (9 pin on NI 9403) LED's in LabVIEW frontpanel doesn't light.

There are two screenshots of project tree and digital input vi.

Can anyone help me, what I'm missing or doing wrong?

When configured as inputs, the pins on the 9403 will return true when they see a voltage greater than 2.2V--connecting them to one of the common pins applies 0V.

Check out the module specs for more info (pgs 8 and 11): http://digital.ni.com/manuals.nsf/websearch/4EC06B18FEFFF68D862574E300195E06

Thank you very much, I didn't notice that this module doesn't have +5V inside.
