I am not a NMEA expert, I just don't see how you would be able to use the 2 different speed NMEA outputs of the GX2100 to the single
input of the c80 without a mux, without losing functionality that is. The brookhouse, although not cheap
, simplifies it and adds more inputs from other devices.
I think I get what you said above.. you want to convert the 2100's nmea port (dsc, etc) to seatalk
and the nmea-HS (ais) to the g80 directly. I was going to go that route
in my system (using a nmea/seatalk converter), but with several different talkers on the line, 3 technolgies, it was proving difficult/impossible. the brookhouse was a nice fit in my case..worked flawlessly and is very flexible, especially being able to hook a pc up to it and the remote
repeater is nice. Plus everything still talks with each other even with the plotter off.
Still the brookhouse is a sweet device, efficient, great support, flexible, customizable, configurable. While not cheap, it is a good value for what it does.
