Hi Frank,

As you probably remember, I use your gadgetpool multiplexer on my boat. It works perfectly well.
I use OpenCpn on a PC as a chart plotter and I decided this year to connect the PC using Wifi on to the multiplexer.
So I added a Wifi access point to my installation.

http://www.usriot.com/p/serial-wifi-ethernet-converter/

Everything works fine except that I can not get the true wind using Wifi while I get it using the USB plug.

Do you have an idea on why I have the true wind via the USB and not via Wifi ?
NMEA sentences seems to be correct :
$IIMWV,112.50,T,005.30,N,A*3A
$IIMWV,112.5,R,005.3,N,A*3C

The relative wind is displayed both by USB and Wifi.

Connections of the whole stuff is as follow :

Best regards

Pierre

Hello Pierre,

I just checked my source codes - and you are absolutely right.
Currently the muxer calculates true wind and sends it to the USB port only.

I guess that comes from the time when I implemented that true-wind calculation for one user who asked for it, and I simply forgot to finish that new function properly.
Most users only needed true wind on the board computer, which is connected via USB port.

I will add sending true wind to the NMEA-Out ports as well.
I just need a couple of days to implement and test it.

Thank you for reporting that.

Best regards
Frank

Hallo again

you also asked :

Quote:
Another question : could you tell me if Seatalk sentences coming up from my tiller (pilot RAYMARINE ST2000+) are processed by the multiplexer in order to have a remote control on the pilot from the chart plotter (PC using OPENCPN).


The multiplexer does receive compass data from the ST2000.
I know that from the time when I tested my first SeaTalk Nmea Bridge with a ST2000+

Regarding the "remote control" -
What you can do is make a waypoint ( or a route with several waypoints ) in OpenCPN and send that waypoint to the ST2000+.
It will than steer the boat to that waypoint.
OpenCPN sends waypoint-name, distance, direction and cross track error via NMEA to the multiplexer and the multiplexer forwards that data to the seatalk bus.

The manual says :
Quote:

In Track mode, the tiller pilot maintains a track between waypoints created on a navigation system. The tiller pilot computes any course changes to keep your boat on track, automatically compensating for tidal streams and leeway. To operate in Track mode, the tiller pilot must receive cross track error information from either:

Bring the boat to within 0.1 nm of track. 2. Press auto. 3. Press -10 and +10 together to enter Track mode. 4. An alarm will sound and the display will alternate between: • the bearing to waypoint, and • the direction the boat will turn to take up the new track


That should work. I never tried it with a ST2000+ myself, but I tried it with other autopilots, and I'm pretty sure it will work with the ST2000+ as well.

Of course you have to make sure, that "sending data to seatalk" is enabled. ( See config tool )

Best regards
Frank

Ok thank you very much Frank. I will now stop scratching my head Laughing

And I look forward to updating the firmware.

My best regards.

Hi Pierre - and everybody else how might be interested.

I just uploaded a new package to our download section.

It contains
* latest Firmware V2.4
* new config tool V1.13

- With this firmware and config tool, you can configure to which port you could like to have sent true-wind data calculated by the multiplexer.

- This firmware also contains some bugfixes for problems we found over the last weeks.
A user from the far north Smile really help us a lot to find and fix problems that could arise when the multiplexer is operated at its limits.
He used all 4 Ports + SeaTalk, some ports set to 38400 Baud and others with just 4800 Baud. In this situation it could come to data corruption due to buffer overflow.

- Since I don't have a NMEA wind instrument for testing, maybe you could test it give a short feedback, so that I know if it works as expected.

Thank you and best regards
Frank

Ok Frank, thank you very much for this update.

As you saw it on the shema of my installation on board, the multiplexer is very solicited too.

So it is with pleasure that I will report to you on the operation of the multiplexer.

Best regards.

Pierre

Hi Frank,

I uploaded the new versions of the config tool v1.14 and firmware V2.8.
Everything works perfectly well, especially the "true wind" data are now being sent over NMEA ports.

Thank you very much for this great work.

Best rregards

Hi,

Is the true wind calculation based on STW or SOG, or is it configurable? I'd prefer SOG if present.

Thanks,

Harri
