hello gang

Because of firmware issues with Symbolic sound's Caparana system , I had to purchase an extra Soundcard. I opted for the MOTU Ultralite MK3 , which works fine.

I would like to 'daisy chain' the  SPDIF/out from the MOTU to My Fireface 800 (So I can use my Fireface Card) , Also I would like to be able to then send the SPDIF out (from my FireFace) to my recently purchased ERGO  from KRK.

Now I imagine that IN/OUT IN/OUt would sufice , but for some reason I can not even get the MOTU to the  FIREFACE to communicate

Could someone help me out on how to set this up ?

Thanks !
