Is it possible to split at single gps signal without amplification for 3 different devices needing NMEA data: Navman 7100eu, Raymarine C70 Chart Plotter and Raymarine ST60+ Tridata?
Thanks. I ended up ordering a Raystar gps to connect all Raymarine devices through Seatalk as you suggest. Non Raymarine devices can probably be connected either to the old gps or the NMEA on the C70.
