Attached are some of the instructions ... additionally I was using 96kHz with a 2048 buffer in the driver as I recall ... the 512 was just set for DIGU mode I think (not 100% sure here). I uploaded the cable specs, but it did not make it through the reflector so Tim is going to post these in the knowledge base and they should be up this weekend. Steve, N5AC
