Problem using NI9205 with expansion chassis NI9151

[Matteo_Orciari]

I'm having some problem using a NI9205 on a NI9151 expansion chassis.

The 9151 is connected to a NI7852R which is in a pxi chassis with a real time embedded controller.

When I`m trying to read the channels, i get all -10V on the first channel, and zero in all others.

I`ve tried DIFF, NRSE and RSE.

Ive tried to use a different module, a different chassis and a different cable.

Automatic discovery of C modules doesn`t seem to work, but I don`t remember if it is normal.

I`m trying to use this AI module in a custom FPGA personality for veristand.

I`ve made a similar bitfile using a CAN C module in the extension chassis and it worked.

Any ideas?

Thanks,

Matteo

Hi,

are you sure that the pxi and expansion chiassis is connected in right way? In the link below in the link below explains how to:

The detection should be automatic, I am attaching a second link of checks you can do.
