I am looking at expanding the network on my boat. I just added a second Lowrance HDS9, both of which are mounted on the console. I have the old HDS7 that I'd like to have the option to mount at the transom or up in the bow depending on what type of fishing Im doing. Currently the HDS9s are linked via network cable and NMEA2000 as Im pulling engine data via the NMEA network. I only have one more Network port available, is there a way to split that port so I can run a network cable both forward and backwards?
