Does the NI MyRIO's AGND need to be connected?

Hi

 

Using the analog output (AO0) of the Connector pin C (p. 6 in the manual) on the NI MyRIO 1900, does the AGND port have to be connected externally to ground, or is it connected internally to the minus of the power supply?

 

Thanks!

Hey,

 

The AGND pin is internally connected to the power supply. It is used as a reference for digital lines.
