DAQmx - Read AI digital values

[MK_MTEngineer]

Hi!

Simple question: Is it possible to read directly the discrete values from an analog input channel?

The result of a "normal" DAQ AI aquisition are DBL samples. In fact that the card converts the input voltage with an ADC into a digital value its waste of memory to use DBL for lets say a 12bit conversion. I use the following hardware, but this should be possible for every card:

- NI PCI-6110

- NI PCI-6711

Best regrads,

Ok found it in the VI "DAQmx Read (Analog 2D U16 NChan NSamp).vi". Seems to be that nobody uses this... i never saw a LabVIEW example with such a simple way to read out the REAL AI data.

Best regards,

Michael
