Converting data for use with Analog I/O on R-Series Intelligent DAQ

[Evan R.]

Description:

Two VIs for converting between analog voltages and ADC/DAC "counts". For use with ADC and DAC chips which provide 16 bit

Details:

Some customers have asked how we can send voltage data to an analog output or read voltage data from an analog input of an R-Series intelligent DAQ board. The answer is to convert.

We know that the A/D and D/A use a 16-bit converter, and provide a voltage range of +/- 10V. The result is that each "count" is +10V + |-10|V / 2^16 volts per count. I have written two VIs to help convert to and from ADC and DAC counts.
