Hello V.GRAF,
Thank you for contacting National Instruments.
The problem may be that you need to reset your board for DAQmx in Measurement and Automation Explorer (MAX).
Open up MAX. Expand the Devices and Interfaces tree under My System. Expand the NI-DAQmx Devices tree. Right click on our DAQ card and select Reset Device.
After you have done this, try running the example again. Cycle through the entire range of inputs using the Data to Write control. If it still does not work correctly, let me know.
