I'm using the NI SH68-C68-S cable with the PCI-6723 analog output card. I know the cable has twisted pairs but does anyone have information as to which ground pins are paired with which analog outputs?

Hi Nader,

      Is this the information you're looking for: What is the PCI/PXI 6723 Pinout?  Or is there other information that you need?  Have a good one!

Thanks but no.  I need to know which specific ground pin on the pin-out that is paired with each signal in the cable.

Hello nader1234,

So all of the AOGNDs are tied to chassis GN.  This means that if you are using referenced Single ended (RSE), it does not matter which AOGND you connect to because they are all actually identical GNDs.

The same goes for Digital GND.  All of the D GND are tied together and therefore tied to chassis GND it should not matter which GND pin you choose.  

I hope that this helps you, please let us know if there is anything else we can help you with. 

Thank you
