Actually I only have one incoming connection from my AIS with both GPS and AIS data sent with 4800 baud. I also have an outgoing connection to my autopilot but since I have not managed to get data into OpenCPN I have not tried to configure that connection yet.
It's all they same that worked in my old Pi 3 and since I CSN see data in SK I don't understand why it's not sent to OpenCPN?

You can check that the data is available at port 10110 tcp connection from the command line:
telnet localhost 10110
If that shows the data the error is in OpenCPN configuration.
When your SK server starts do you see any errors in syslog? The only reason I can think of that would prevent 0183 data appearing on port 10110 that some other application has that port already open.

To know if you have network conflicts go to openplotter network app and click on "addresses and ports".
Are you sure you have 4800 baud for GPS+AIS?

Still don't know why it didn't work. I disconnected everything, removed all serial and signalk connections, rebooted, connected and set it all up again in and then I got AIS and GPS-data in OpenCPN!
Now it's just NMEA-out to the autopilot that doesn't work. It's all set up as in the manual (NMEA multiplexing) but no data transmitted. I think something is wrong in OpenCPN, NMEA-logging says inbound data is filtered and outbound data is removed.
Data from AIS/GPS is 4800 baud as it is also sent to the VHF and it does not support higher speed. Another thing to fix when everything else is up and running...
