Fred will need to jump in, but what I recall is SeaTalk NG *is NMEA 2000* more or less, you just need to adapt the physical connections to each other. Joe Coquina

Wish to also connect B923 to a65. B923 has Nema -0183 and Nema2000 connections. A65 has SeatalkNG and Nema2000 ports. A65 currently using SeatalkNG port to communicate with i50/i60 instruments. Nema2000 port unused. Power connector has only three prongs so do not believe this model has the Nema 0183 wiring How do I most easily (and cost effectively) connect the B923 to the a65 so that I can see AIS targets? Can I simply purchase a SeatalkNG to Nema2000 cable and plug B923 into SeatalkNG backbone? https://www.defender.com/product3.jsp?path=-1|344|2028705|2028879&id=1108756#<https://www.defender.com/product3.jsp?path=-1|344|2028705|2028879&id=1108756> That seems too simple a solution and too good to be true. Alternatively do I need to set up a Nema 2000 backbone in addition to (and separately from) the existing SeatalkNG backbone and then connect to the Nema 2000 ports on the a65 and the B923? Will this cause issues since the a65 is also connected using SeatalkNG port to the Seatalk backbone? This seems very complicated compared to the older Nema 0183 connectivity.
