How to access counters in cDAQ9174 / NI9403 with C / Matlab

[Odysseus]

Hello,

I read that the cDAQ9174 has four counters available. However, they need to be interfaced through some other Card and they're now directly available to the user. How do I do that with the NI9403 digital I/O card? How could I do that with LabVIEW but with C/Matlab?

Thank you

Hello Odyseeus,

hope this helps

Create a Counter Input Channel

this do not work with the NI 9403, because there are not PFI line available. You need instead a module like the NI 9401.

Thank you Alexander for the reply. Sounds like I need to purchase a different NI card. How do i find out which cards have a PFI-line?

Hello Odysseus,

normally all moduls with 8 or less DIO inputs.
