Be careful with that Zeus sync tool; when I tried it on a plotter, it treated the external web app source as the "source of truth" and wiped out all the tracks/routes locally created on the plotter.

Hey Nick,

I've written some code that pushes simulated boat data to Expedition, using the Expedition wire protocol over UDP.

Out of all the data fields I've tested, the only ones that do not seem to work are BSP and GPS-related data such as Lat/Long.

The BSP one has me stumped, is there another field of data that Expedition wants, for that to register?  I can see it coming through on the raw data.

For the GPS, I have the network selected as the GPS source and am publishing the following fields/values (with the checksum at the end.)
#0,48,${row.Lat},49,${row.Lon},41,${PDOP},39,${GpQual},43,${GpsNum},44,${GpsAge},45,${Altitude},46,${GeoSep},47,${GpsMode},146,${GPSTime}

For the values, I'm using real values from one of my log files while testing.

Does Expedition not accept the Expedition instrument type as a valid GPS source or are there extra fields that I should include?

Here's a copy and paste from the Raw data window for two updates.
#0,50,38.6,15,23.2,51,11.371,17,-0.2,1,11.728,13,42.7,2,118.5,3,10.42,18,-4.2*3C
#0,48,-27.83562,49,153.605404,41,1.4,39,1,43,12,44,0,45,13.81,46,0.01,47,3,146,45464.92426*0D

Any suggestions?

Cheers.

Hi Volker,

How are you expecting those values to show on the plotter?  When viewing the data, you must look at the external channel source data (on your plotter), not the default data values such as "VMC".  In case that wasn't clear from my earlier reply.

I'm surprised you're able to connect with web sockets without an H5. I did not think you could connect straight to the plotter with that protocol.

To my mind, your plotter is only on the n2k network (not ethernet) and your expedition will have some kind of interface to get it onto the n2k network too (Like an Actisense), unless you have a processer that's interfacing on both web sockets and n2k.

(I do run my plotters on ethernet, but that's for chart/master/slave sharing and FTP access to transfer waypoints.  (Zeus 3s))

Sorry if I'm wrong about this.

Craig.

Also, let me know if your measured boat speed is right?  I looked at my logs the other day and the number matched the BSP, which shouldn't be the case.  I haven't drilled into it yet to confirm that I'm logging the correct ID.

Hey Sparky,

It's been a few years since I've used Raymarine gear. Still, I remember that I could send the active waypoint to the Raymarine instruments using the various appropriate PGNs, but this was likely on older E7-type plotters with older network setups.

Hopefully, the newer ones aren't like B&G Plotters, which won't accept any navigation source except for themselves.  (Though there are tricks)
