Yes the Lucid is an AES-EBU interface.
I am routing 8 channels of analog in/out from the Lucid into the H8000FW to connect to the DAW over firewire directly (bypassing DSPs). – Firewire1
I am routing 8 channels inside the DAW to the H8000FW over firewire as well (4 to DSPA, 4 to DSP B) – Firewire2

It is difficult to describe it further without a block diagram, but I started with the ADAT & AES8 I/O setting and modified it. I am not using ADAT at all and just want access to the two DSPs seperately from the DAW.
