Problem when configure polarity on PCI-6023E

[Stephan Zuiderwijk]

I tried to set the polarity of an analog input channel with AI_configure. When I call AI_Configure with polarity Bipolar(default) anything works fine. but when I change the polarity to unipolar, the status code -10003 is returned, indicating that the value of my parameter is invalid. The PCI-6023E is software configurable, isn't it?

The AI of the 6023E can't be set to unipolar ! Have at look at page A-1 of the user manual.

Stephan;

The 6023E board can only be configured as bipolar mode.
Take a look at the board Users Manual to double check that information.
