I ordered a BNC cable. So when that comes I can use S/Pdif coax digital with wordclock @ 88.2k?

I tried choosing optical as the digital in but it says sample rate too high, I tried sending both S/Pdif and AES format optical.

 Strange that ADAT works at 44.1. It  must be going through a sample rate conversion somewhere because I'm recording at 88.2

I'm looking at a RME HDSP 9632 which has an AES-EBU XLR breakout option.

I could use mic cables to plug that in?

Thanks
