Are AOGND and AIGND of USB-6366 X-series connected internally?

[NORTH1997]

I'm trying to use USB-6366 X-series for analog output, but I can't find AOGND on the front panel, is it possible that AOGND and AIGND are already connected internally? Where can I get this information? I don't see that information on the datasheet.

Hi NORTH1997

AOGND should be found at the pins highlighted below.

The grounds for the USB-6366 are tied internally, but you should be using the AOGND if you are using an AO channel.

What you show me is the interface of the 6636screw terminal, I am using a 6636 (BNC), their panels are not the same, as I showed you.

The BNC shell/shield of the Analog Output is AOGND.
