One is to install the SignalK "SignalK to NMEA0183" plugin, and test to see if you are getting anything out on TCP port 10110 (you should). Don't forget to enable to plugin, and check the NMEA strings you want sent out. If you still can't see it, try also installing the "UDP NMEA0183 Sender". That plugin sends out using UDP and does allow you to configure the network (10.10.10.255) and UDP port you need to send data out on (10110 is fine).
If you don't want to mess with SignalK plugins, you can configure an outgoing network connection in OpenCPN. With that one, you have full flexibility to choose port number, TCP or UDP, addresses, etc. Of course, the downside is that you need to have OpenCPN running on your RPI server.
Thanks again for your reply and I'm reasonably technical but I don't understand what is meant to happen here so let me read up on that first before bothering you. What I did on my iPad is use a browser and go to <RPI>:10110 - that didn't work but when you say getting something out of TCP 10110 - I'm guessing that a simple browser won't do the trick.
Again - I think these are basic questions I need to research first not to bother you too much. If I get stuck: I'll come back to you.
