(DG) Axiom and Knot meter upgrade

I have a 2012 Leopard 39 setup with a St60+ instruments. TriData, wind and St6002 autopilot connected to a C90w. I am removing the C90w and upgrading to an Axiom 12 with a RKM-10 remote, and an Quantum radar. I also want to add a knot meter input.

Question #1 Is the system diagram I created correct?

Question #2 Which model of knot meter should I purchase. One that connects to my existing St60+ Tridata or one that connects to the SeaTalkNG network?

Thanks
Steve
