Re: Seatalk to Seatalk NG
You have to have the 5 port converter, no other way around it.
Once you get it then it's just plug and play for the 60+'s to the NG.
Go to RM site, they have nice network diagrams. If you have more than one NG device you'll need a network hub (different 5 hub piece).
Lessons learned are opportunities earned.
