Anybody know how to connect a Garmin 198C to a Furuno 1622?
I have the manuals from both but they don't use the same terminology.
Garmin uses NMEA Out COM 1 Tx, NMEA In COM 1 Rx, COM 2 TX, COM 2 Rx
Furuno uses RD1-H, RD1-C, RD2-H, RD2-C, and refers to Navigator wires as
TX-H, TX-C, and Sounder wires as TX-H, TX-C.
I emailed Garmin (they've been prompt before) but haven't had an answer yet.
