I’ve got a C80, not sure how applicable this is to a C70.
I had the same issues with the supplied cables
not fitting in the metal tubes to the plotter and not being long enough. The original plan was to install Seatalkng network for the SR50 and my AIS
so I did the backbone kit plus it fit in the metal tubes. Turns out the C80 can only accept/process AIS traffic via NMEA 0183
. So yea, I now have a Seatalkng network just for the SR50.
Long term my thoughts are to get the kits to convert the analog instruments
and NMEA 0183
traffic to Seatalkng so I can work
with that data across iPads and alike. I’m hoping (?) I can convert and haul the AIS data from 0183 up to the plotter via Seatalkng and convert it back. Seems messy.
I did the install last year so I might be missing some if the details, most confusing part is the C80 is very picky on which inputs which type of traffic comes in.
