My Cerbo GX MkII is installed about 20 cable feet from the nearest port on my NMEA2000 network. The Victron VE-Can to NMEA2000 cable is not long enough to reach and I need to either add a coupler and additional Ethernet cable to reach the Cerbo GX or start with an Ethernet cable of adequate length and add a NMEA2000 connector to one end so it can be connected to the N2K bus.
I am feeling somewhat cheap by balking at a $70 cable and $15 for the extension cable and connector, but the DIY cable is only $10 for the N2K end since I already have plenty of Ethernet cables. Why wouldn’t I just make my own?
