360 to helix connect with link?

[emeryrob3]

I’m replacing two 998’s with two helix units. One at bow and one at console. I’m also adding non mega 360 to bow. Since 360 connects to Ethernet port how will I link the two helix’s? Is there an Ethernet splitter cable? Or do I need to get the 5 port Ethernet box? And still how would it connect with the bow unit hooked to 360? Thanks I hope this is simple solution

Will need the 5 port box. The two units and the 360 will all connect to the ethernet port.
