[CA] SPX computer conecting to Garmin 4212

[tgsail1]

Chuck- I just noticed this thread. In our new system we have an SPX-10 with a p70 control head, an i70s and an i50 depth. Our chartplotter is a Garmin 741. We also have a Standard Horizon Matrix 2100 VHF with AIS receiver. The Garmin has both NMEA 0183 and NMEA2000 connections. My plan was to connect the Garmin N0183 out to the VHF N0183 in and use the Garmin NMEA2000 to talk to the SPX-10. Will that work? If not, my other option is to connect the Garmin N0183 out to the SPX-10 N0183 in and also to the VHF N0183 in (note although NMEA0183 is single talker multi-listener, Raymarine does not recommend multiple connections to the NMEA0183 in). I could also connect the VHF N0183 in to the SPX-10 N0183 out, but I think the GPS data are not forwarded on that port.
