Show control for etcnet3 house light system with a hog4 full boar

My question is simple in its base form. It is that I need to know what interface do I need between the console and the house to control it. 

the house system consists of a paradigm based etcnet3 with sensor 3 cem. All rooms have an etcnet Ethernet port, but keep n mind that this system was recently upgraded from etcnet2 unison based system and those ports were from then. I don’t know if that makes a difference. I have all the dmx address’s and ip address’s of the components in the system. I’ve already done all the mapping to know hat controls what. So I just don’t know if or what I need now in line to properly control the system. Any help. Thank you
