So I was reading panbo
and came across this nugget:
If you know your display's IP address you can use a GoFree enabled plotter as an Ethernet TCP server for NMEA 0183 data. Go to Network > NMEA0183 > Ethernet for information on how to connect your app. My HDS is only connected to NMEA 2000 sensors, but it generates a full NMEA 0183 stream with all available data (sensors, GPS, AIS). It even includes a non-standard sentence so that air temperature, heel, trim, barometer and rudder data can be transferred. Very well done!
I am a bit numpty at this marine
networking - but let's assume I have the HDS connected to onboard network, and my laptop
is connected to the same network.
I should be able to add the TCP stream from the HDS as a data connection, right?
But does OpenCPN
recognise all the different sentences in a TCP stream? I ask because I understand that most NMEA0183 is 4800 baud but AIS
is 38400 - would I need to add the TCP stream twice at different baud rates? Or will OpenCPN filter and use as appropriate all the sentences in a TCP stream?
Just trying to figure out if this would work
as a nice backup/second chartplotter
solution before I spend $$$.
