I just purchased a couple of Solix MEGA 12 & 10 graphs, 360, and Ultrex for my boat. I'm wondering is I need to purchase a Ethernet hub to get all of these units connected ? I have two wires coming out of both the 360 and Ultrex. One of the two on both I know are the power wires I got those hooked up and getting power. The other two wires are what I can't figure out, are these my Ethernet cords? One is male and the other female and they connect to one another, but I'm pretty sure that's not the way they are supposed to be hooked up. The Solix doesn't have a place to plug either of these wires either. Do I need to purchase additional cords to connect them to the Solix? I've attached a diagram of how I have things setup to help explain if my wording is to confusing to read.
