The H8000 family routing is fairly sophisticated, and thus not simple. For your purposes, I would suggest that you use one of the Factory Routings,either "ADAT 8 Track A,B", "ADAT A || B" or "ADAT A->B" as appropriate. See FACTORY ROUTING CONFIGURATIONS on p.26 of the UM for more information.
Once you have this working, you might want to download the Routing Utility from the H8000 Support Page to learn more about the machine's routing capabilities.
