Cubase input from RME FF400/Digimax

I have a Mac mini running OSX. RME fire face 400. Presonus Digimax 8 channel feeding the RME input via ADAT. With a mic plugged in to channel 3 on the Digimax I cannot get any signa in Cubase. I tried Logic Pro X and it came up on channel 13 woth no problems. Any thoughts ?

Many… not properly set up… would be the first…
Can you provide a screenshot of you audio connections?

I rebooted everything and lo and behold it worked. Channel 3 on the Digimax came up as channel 13 in Cubase as it was in Logic Pro.
