I 'm wondering if any of you smart guys can help me? I would like to connect the smartcraft system to my raymarine E120's so as to get engine data displayed. Now I understand that the E120 likes NMEA2000 and the smartcraft works on J1939, so I've found a NMEA2000/j1939 Conversion box from Maretron and wondering how to get an output from the smartcraft into this box and then do I need one from each engine.? Also what happens if I put one into each screen if they are networked together through HSB2 - will it screw it up? I'd appreciate any thoughts or directions to take or am I just trying to hard and it's not possibe? Thankyou in advance.
