Problems with ADAT card…

I’m responding to myself here, with kind of a question. I’m thinking that this must be a clocking problem, because by them selves both interfaces worked fine, no clicks. I’m confused on ADAT clocking. I understand that there has to be a master clock and the rest are slaves, when I use the BNC in’s and outs, but what about the ADAT. How should I set the clocks on the interfaces when I’m using them with ADAT out into the ADAT card of the Utrack. If I’m setting the software on the Utrack to clock from ADAT1, then wouldn’t the interface, in this case the Audient, wouldn’t it need to be set to Master? Boy am I mixed up on this one. Sorry to be so tedious here. Marc.
