Reply to Setting up my Numark ndx400's and M101 to vdjpro

Can someone please help me setup my cdjs and mixer.
I have literally just started mixing so please talk slowly and clearly ;-)
I bought an external usb soundcard from Amazon a digiflex, it says it has 6 channels
All the connections on it are 3.5mm so have bought a few rca to 3.5mm cables.
How do I go about hooking it all up to vdjpro. ?
Cheers
