MOTU 828 MKII input into Logic Pro

Question

I posted about this earlier, but I think I can simplify/clarify:
I'm using 8 channels of ADAT pre-amp input connected to my MOTU 828 MKII.
Cuemix (MOTU's monitoring software) shows that all inputs are functioning properly.
But when I try to choose an input channel in Logic, I have a problem:
All 8 channels come through inputs 13 & 14 in Logic. Logic will allow me to select inputs 13 through 20 (they're not grayed out), but there's no audio coming to inputs 15 through 20. And, yes, I'm pressing "record" to enable the track.
I should be able to assign inputs as follows:
ADAT 1 = Input 13
ADAT 2 = Input 14
ADAT 3 = Input 15
ADAT 4 = Input 16
ADAT 5 = Input 17
ADAT 6 = Input 18
ADAT 7 = Input 19
ADAT 8 = Input 20
Any ideas on what's happening here?

Answer 1

The reason it is 2 out is because Logic doesn't recognise the names of the inputs. They are simply numbered. So, the front 2 inputs on the MOTU are inputs 1 and 2 in Logic. So the next input in Logic is 3, but the next input on the MOTU is on the back..... which (rear of MOTU) is input 1..... and on it goes.
Logic 4, Motu (rear)2.
This got me at first until I realised that Logics input chanels were just numbered straight through, not differentiating between front, rear, analog, ADAT etc.... I think inputs 11 to 18 in Logic correspond to ADAT 1-8 on MOTU.
