OK, here goes. I have 2 - 898's installed at the console, a helix 9 DI Gps at the bow and ether net AS ETH 5 PXG switch connecting the three units. I also have two temp sensors (one to each live well) one connected to the helix 9 and the other connected to one of the 898's. Additionally i have a terrova with i-pilot link and two Gps external pucks ( one with heading sensor) installed as well. I have the transducer that was included with the Helix 9 installed on the foot of the trolling motor and the internal transducer in the terrova connected to the ether net switch. On the stern I have two XHS 9 HDSI 180 T transducers installed side by side. My question after all of that is what is the the best way for me to integrate all of this. And is it ok for the transducers on the stern to be installed side by side?
