Data acquisition from NI9205

[win2023]

Hi,

I am trying to acquire data (Voltage) from 12 channels from NI9205 but I am getting the following error -

Possible reason(s):

Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.

Property: AI.TermCfg
Requested Value: 4
Possible Values: Differential, RSE, NRSE
Channel Name: Pressure_81

Note: I am using RSE, albeit others are supported too in NI9205.

I have attached the virtual channel part of the code. This code actually works with NI9216 for Pt100.

Please help !!

"4" is different to "RSE"…

Do you spot the coercion dots in your image? Remove them by using the correct datatypes!

Yes, I see the correction dot, however can you please suggest the correct data type? It would be of great help.

Copy the enum from the shipping example Or use the correct value for RSE which is 10083.

LabVIEW basics: right-click the input of a subVI and select Create constant to get a constant of the correct datatype…
