Collating and Displaying NMEA2000/Seatalk Data on Laptop or Tablet

I'm sure I will figure out Open CPN but it is particularly awkwardand non-user friendly. I simply cannot get any chart addresses into it except NOAA - and the instructions/manual is of no help whatsoever.

I wouldn't have bought Raymarine by choice, to much was already there to bin it.To me the name Raycontrol suggests it controls Raymarine - it doesn't, it merely operates a remote display from which you can't control the boat! That's hardly my idea of "controlling" something!

Anyhow, back to trying to get charts into this bloody CPN.

I see that some AIS transponders have a USB output. It looks as if that might get the info I need into the plotter - is that right?

I'd suggest you start a new thread about your OpenCPN problems, i'm sure you'll get them resolved with some help from the forum.

Raycontrol enables the MFD toe remotely controlled from an Android or iOS device, you can do anything from the device that you can do on theMFD. What chart plotter/MFD do you have ?

Not sure what you mean by "into the plotter".

Some AIS transponders do indeed have USB outputs and/or wifi. For instance, the Emtrak B100 outputs data via USB. If connected to a Seatalk/N2K network it should output everything via USB (needs a Seatalk to N2K adaptor to use Seatalk). Some of the 900 series also have Bluetooth or wifi.

I have a slight bias towards Emtrak devices, as i do supply them, because i like them, but other makes are of course available.
 
It’s more an intellectual exercise for me. It’s running on a Raspberry Pi Zero which doesn’t have the grunt for openplotter, but doesn’t draw much power either. Currently receives and logs data. Just building a web interface exactly how I want it.

+1 for GMI20. Really like mine.
It's signalk which does all the work, should be fine on a zero and is such an amazing swiss army knife for data on a boat it's hard to see why not have it running.

Anyone know why this is being rejected by CPN as not a valid URL?

Where are you trying to put that into opencpn?
If it's in the chart downloader tab then it says it's not a valid url because it's not a valid url.
 
I did give it a look quite a while ago. Will probably take a look again. I couldn’t find an iPhone app I liked for displaying data.
Signalk has some very good apps for display, all on a web page so viewable on any device that can view a web page. KIP is my favourite. Unfortunately not included in the signalk online demo

Though yet to actually try it on a zero, htop show low processor resources being used to run signalk on my Pi3 so should be OK....

If you want to use VMH charts with OpenCPN, just give them a call and tell them the charts you want and get them sent to you on a USB stick. Easy.
 
For the OP, if you want to display realtime NMEA data, try ManMonPc (free download) which runs on a Windows laptop. I have used this for many years and it shows great time histories on wind, depth speed. I find the true wind speed and direction history like an extra sense. All data is received on serial/USB and can be logged to disk for historical analysis. I use it exztensively, but would like to move on and am keen on Signal K etc, but not at a stage to find how it can replace NavMonPc just yet.

If it aint broke....
 
But I would not call it one click away, the website is bewildering to say the least! No obvious numpty guide for yachties.
Download this installer file >
https://github.com/SignalK/signalk-server-windows/releases/latest/download/signalk-server-setup.exe

Double click to run it. Have a quick coffe while it installs. That's about it, I just reinstalled it. There was a ' do you want to log ' message box which I said no to. Then right click on the 'start signalk service' link on the desktop and 'run as administrator'. Signalk is now running in a website at localhost:3000

You can turn it on and off and get it to auto run in the task manager services tab as well.

Give it a go, didn't take long just now but a load of the bits might have been downloaded already.
