Openplotter hardware

I would use a NMEA 2000 (Raspberry Pi) hat. There are NMEA multiplexer devices that can multiplex many NMEA 0183 signals into one NMEA 2000 signal. You can also use a Ethernet NMEA 2000 gateway. It provides the NMEA network communication as a TCP and an UDP data stream. Multiple gateways make it possible to connect many NMEA 2000 networks together (star topology). If the device supports it, you can write to a TCP/UDP port as thus copy data from one NMEA 2000 network to another NMEA 2000 network. Ethernet connects to a router, or a hub, and make it possible to read the NMEA 2000 communication between your boat's electronics - from your computer.

What kind of USB to rs422 is that ? I dont understand if its an USB to RS232 or to RS422 or if that is the same converter that we need to use when plugging in NMEA 0183 cables...

Hello thank you for your video. Have you try to connect an old depth sensor with coaxial cable after separate and unbraided the + and - pole directly to rs422 adapter? Thank you in advance.

[@muckleyj]

No. From my experience, typically, instruments need to go to their respective control head and then the control head will output a NMEA 0183 signal. That's what I show in my video.

@@muckleyj ok thank you for your answer

[@ETIC-U]

Thanks bro great stuff

[@joel383]

Do you have a source link for the Hub? I can't find a reasonable one, like yours, that will ship to the US.

[@sonnos8653]

Looking simple and easy! Have you tried to access your nmea data from an iOS device? I was thinking it needs a mux server to put the data streams together before output. Good job!

[@dontsplatmatt]

This is awesome. Couple quick questions for ya. What role do the Rs422 serve? Are they necessary? Also what's the purpose for the large router as opposed to a smaller USB dongle? Thanks!

[@dontsplatmatt]

@@muckleyj Thank you that definitely points me in the right direction. Are you still running this setup?

[@signalpresent]

To what autopilot are you sending data?

[@muckleyj]

An older SIMRAD unit that takes NMEA 0183

[@futhaiter366]

High risk and worthless for practical use, because only receiving ais is useless. Really important is SENDING ais, so other ships can see your in time.

[@tmilesify]

Any suggestions for a "cheap" AIS transmitter?

[@mhansl]

Far from useless. If you’re crossing shipping lanes, you need to see the heavies. Not to mention, AIS transmitters are still in the upper three digits price range.

[@Nardypants]

Lol. Total disagrement here. Small crafts benefit greatly from receiving AIS, as observed by my experience of the St. Lawrence Seaway at night.

[@AthelstanEngland]

Sending/receiving AIS is nothing to do with this setup specifically, sounds like an armchair comment to me! And several sailing channels use similar setups and have been cruising for a couple of years with them.

[@AthelstanEngland]

@@Nardypants agreed.... they also benefit from turning AIS transmit OFF when passing piracy areas too.
