NI 9401 with NI DAQmx

Hello,

 

  I'am I new user of the DAqmx, I use a Ni 9401 ( 8 DIO, 5 V/TTL, Bidirectional, 100 ns) to have angular speed spped with a NiCdaq 9174. 

  I start doing a Labview VI but I have some errors, the first one is as shown in the picture.

  If somone used with the NI 9401 can help.

 

Thanks a lot,

 Firestorm100

You've selected an incorrect channel for the DO operation - you should be selecting DO channel of 9401, instead you have selected a AI channel of some other module

Hello,

 

What you have in cDAQ1Mod1 is an analog input module and you cannot configure a digital Output task with it.

Looks like you reused a DAQmx AI example and the control is filtering only AI channels.

 

Try deleting the control and creating a new one from the Create DAQmx Task API.
