Topic: HDSP 9652 + Motu 8pre in Windows 7 64bit

Hi,
I just installed my first RME product on a Windows 7 ultimate 64bit system and all seems to have gone swimmingly. I rebooted and TotalMix has appeared on my screen.

Essentially for the time being I would like to use my Motu 8pre as my input and output stage via TOSLINK. At present I only have 1 TOSLINK cable which I am trying to use as an output from the 9652 card. What I have done is ADAT on the card to ADAT in on the Motu 8 pre. I don't know how to set up the inputs and outputs in TotalMix or my DAW (Reaper 4) so would love it if someone could guide me through the process. Any help whatsoever would be great!

Thanks
