RME Madi hdsp - PT11

Upgrading very old system. Need new PT 11 rig to accept RME Madi fiber cable from Logic slave computer. Can someone recommend what I need on the PT rig to receive the incoming ? Just a another pcie Rme Madi on the PT rig (connect card-to-card), or is there an interface required in-between the two?

Thanks for any advice.
