PCIe-6323 analog inputs RSE problem

[CE-EM]

Hello,

I have a PCIe-6323 card and connected a signal to AI 8. When I go to the testpanels of the device and try to read an RSE signal on AI 8, nothing is measured. When I read it on AI 0 in the testpanels, I see my signal? I know AI 8 is shared with AI 0-, but I'm using RSE. What happens here?

Thank you

Did you connect signal GND to AI GND, too?

Hi GerdW,

Thank you so much for your answer, Yes I did. The problem is all the (AI +) work and I find my analog inputs but with all the (AI -) I find 10.8 VDC (i use the test panel of NI MAX) the max of the card SCB 68A.

I really don't know why

Hi CE,

when you create a DAQmx task in MAX it will show you how to connect wires to your device. (I think you get the same in the DAQAssistent ExpressVI, but I'm not sure about this one as I don't use it.)

Did you connect the wires as is shown in MAX?

Hi GerdW,

Yes i did but the same problem. Now i check the datasheet of my card SCB 68A. it seems like i must do a special configuration to make the (IA -) connected to AI GND. Is it true?

Thanks for your help
