I purchased an Apex 13 to put on the bow of my Z518. I moved my Solix 12 G3 to the console. So, when I connect the ethernet cables. Apex to Solix direct to each unit and then Ultrex (si/di) to 5 port hub or Apex. I also have 360 with a y cable. Transducer cables direct to each unit. I wanted to confirm best way to set up. Thx
