Olly. Interesting, - I assumed you had a NMEA2 from this post being in the NMEA2 area? But you mention ports 1-3 and 5? Do you actually have a NMEA4 ? 4 (P1-4) inputs, one (p5) output? That does open up more possibilities! It would help greatly if you have a simple ‘wiring diagram’. So often it is p...

Follow up: I think I now see from earlier posts that you are trying to send the Multiplexed output from the NMEA2 ("P3" =Pins A3/B3) to a TackTick NMEA wireless interface. To do this you presumably have already set the UDP>P3 . But you need to know the Baud rate to use: (and connections). The Manual...

I have got everything plugged in on a test rig now When on simulate I can get data to the instruments and all works well The issue is that the iRegatta app is outputting the attached sentence which none of the systems can read? Is this something that the multiplexer isn’t reading right? Olly, if I ...

I bought the NMEAwifi 4 unit to link into my signal K server on a Raspberry Pi4. Signal K running OK. I want to enter simulation mode and see if my pi can see the demo data. Are there any 'idiot' guides to configure the units to talk to each other? Any help would be appreciated as the multiplexer o...

Bonjour, Dans les traces NMEA je vois que la phrase VHW est fabriquée avec uniquement ST20. de ce fait il manque les infos Cap true et Cap magnétique pourtant présente dans HDG et HDM. Cela provoque un affichage incohérent sur ma tablette, Sailgrib prenant en priorité VHW avant HDG. Je peux filtrer...

Joel, Verizzen. I must also apologise. I had discovered and corrected that bug in some updated code Luis and I called "V16", but we failed to publish it in the Binary updates for NMEA3. The code corrects the bad COG in ST53 and also bad XTE in datagram 85. It also adds an automated (RMC/GPS)COG to (...

I had previously written a post with advice regarding Navionics in the nmea2 forum, which has grown as I have identified more navigation Apps that can use features of NMEA2/4 and now NMEA3. To avoid two posts with very similar data, I will include here a link to the main post that is occasionally up...

Alfredrive.. With the NMEA2, if you can connect your Raymarine Autopilot NMEA input to the NMEA2 "output" (A3/B3) then you should be able to route GOTO waypoint commands from a suitable navigation app. Use TCP>P3 to route from TCP to the P3 output of a NMEA2. UNFORTUNATELY, The Navionics app itself ...

One of the great things about NMEA3 is that it can use its Seatalk "output" capability to simplify connections to Raymarine autopilots, and avoid the need to connect to the autopilot using NMEA. But I discovered a small Seatalk issue in V15 where Bearings to waypoints (generated by InavX, but the sa...

Most users will use a GPS (mushroom etc) on the boat to support the boat VHF DSC, and so will connect the GPS serial output to the VHF, and also to the NMEA4.. But if you have a Tablet with GPS, it might be helpful if the Tablet could send GPS data to the NMEA4WiFI, and then you can send this "out" ...
