cRio NI9215 wrong values

[zerosun]

cRIO 9014-LX50

cRIO 9114 back plane

C-Series  Moduls AO NI9269/AI NI9215

Labview 2009 SP1

App:

Generate voltage value with 9269 and

Measure the voltage with the 9215

Error:

Channel AI0, AI1 work fine, AI2&AI3 don’t work.

Even if I short cut the Input of AI2 and AI3, I measure a random voltage.

Dose some no this problem I don’t have any idea what that is. I already changed the NI9215 but the error stays the same. I also changed the slot of the NI9215. I recompiled a couple of times.

Hi @ all.

Problem solved, the connecter of the NI9215 model was not correct connected. J one week of search.
