Got my Ultrex mount 360 installed. Connected the Ethernet cable to the Ethernet hub. Also have my Helix 12 and 10 connected to the hub. Connected the 360 to power. When I power up my Helix 12 at the bow and go to system status the 360 shows disconnected. I see the heading sensor and if I go to the menu and network I can see my other graph but nothing for the 360. I verified there is power to the wires I used for the 360 and checked the Ethernet cables and connections. Does the 360 need to be in the water to work? Not sure what else to check.
