Problem using NI-PCI6713 DAQ board

I have a problem using the analog output device of my NI-PCI6713 board with
RTLinux

I installed comedi v66 and comedilib v20.

My card is recognised, ./info works correctly. Digital Input/output works
good.

But comedi_data_write(.....,0) will give 0.10V  and
comedi_data_write(.....,4095) will give 0.12V.
This is the same on all channels.


The card works good on windows and a different RTLinux computer running v65
and v19 of comedi and comedilib.

Has anyone had this problem ?

Hows could I fix it??

Do I have to compile RT Linux kernel again ????

thanks for any comments...
