Routing / new to Cubase - using RME Fireface 800

New to Cubase (and Cubase 8)

While my setup appears to be hooked to the Fireface 800, I see all in/out as ‘‘inactive’’…

All I get when I try to set a IN or OUT to a track in Cubase is a ‘‘Input 1, Input 2, Master Out’’

As I am using ADAT channels from the Fireface to an external mixer , I want access to all stereo channels of course.

What am I missing so I can select IN and OUT for each trackm just as I can easily do it with Pro Tools, Logic, or in the past with Sonar under Windows ?

Thanks,
Rob

hit the F4 key and you can setup ins and outs from there.
