Thanks, SUKARA. I have clicked the button on this. I've read that you have to pay attention to the plug's pin-outs to be sure you insert the plug into the motherboard header using the correct wiring orientation, or you could fry both your board and the SPDIF module. I'll be careful... !
Here is the pin-out diagram provided on the Amazon product page for the SPDIF module that I ordered. Looks compatable with the diagram in the MVF user guide. I just need to pay close attention when I plug the module's connector into the board to ensure the connection is correct and not reversed.
