NMEA2000 to Fastnet (B&G) converter?


Recommended Posts

Is there still no way to convert a modern NMEA2000 signal into an old Fastnet signal? I'm considering upgrading my H2000 system to H5000 but it's really more money than I can motivate to swich everything at once. I would like to use my old 20/20 displays for bsp/TWA/AWA and Target speed/ Optimum wind angle if possible. Is there really no way to use the older displays with the new processor? I'm seeing sailmon can interface with both N2K and Fastnet, but adding a full sailmon processor on top of the H5000 Hercules seems like overdoing it. Is my only option to start from scratch?

Go and check out the B&G website or contact your local B&G supplier There is a Fastnet to 2000 converter available which is only around $200.

Thanks I have it, but it's only a one-way converter so I can use it to get N2K fram a Fastnet processor (in my case into expedition) but not to get Fastnet out of a N2K processor which would be the case if I bought the H5000 processor and kept my old Fastnet 20/20 displays.

Can’t fastnet accept 0183 inputs? Maybe the new computer can output in that format?

The displays do not take NMEA0183 as far as I know - the old H2000 performance processor should be able to take NMEA0183 but I'm not sure which sentences it would accept. Also I would prefer tu run only one processor and remove the old H2000 and H2000 performance processor completely if possible.

Ah that was what I was suggesting, which I understand is not ideal. Basically run two separate systems with the fastnet to N2000 converter into the H5000 and use N0183 to feed data back to the H2000 computer.

Another option is to use the Zues2 or 3 chart plotter as they have a N2K and 0183 interface (send and receive) which does work both ways.

This was covered in these two threads recently

 Since you can't be bothered to use the search function I'll repeat it again here

You'll need to find out which of your FFD displays are NEMA capable. It'll be the one with the blue and red wires, probably attached to your GPS's NMEA0183 output. This is spelled out in grotesque detail in the manual, which is freely available online in PDF format. From there you can wire in any number of NMEA0183 to NMEA2000 multiplexer fun time devices ranging from $150 to $250. There is a remote possibility that someone shelled out $$ boat bucks for a Hydra 2000 but not also wire it up to a GPS, in which case it is possible that yours does not have NMEA0183 on at least one of the FFD.

Works great on mine. Best of luck.

Thanks, I think our needs are slightly different. From what I understand you´re running H2000 as you main instrument system and you’re trying to complement it with additional data. I’m trying to scrap my H2000 processor and go to H5000. All I’d like to keep is my three mast 2020 displays. They work just fine and getting three N2K ones is £2,100 I’d like to spend on more crucial parts as a full H5000 Hercules installation will be a very expensive upgrade no matter what.

I do have the a NMEA FFD as well as a Performance processor which according to the manual should primarily be used for NMEA input if available. But I thought they both required me to keep running the main processor for the H2000 system. Do you say an NMEA input to the FFD could be wired directly to the 2020s with no main processor? I thought contrary the manual stated that an NMEA input to the FFD might very well only show on the NMEA FFD.

From the manual I read ...

"A NMEA Full Function Display (FFD) can be used to interface NMEA 0183 data to a Hercules system. The Performance Processor can also be used as an interface for NMEA 0183 data to the Hercules System. The Performance Processor has two NMEA inputs and outputs, (one of which is disabled if the RS232C interface is required). In the case of multiple NMEA inputs and outputs it should not be assumed that data input to one device will be available for output from any other device,. E.g. Inputting Latitude and Longitude to the NMEA FFD will not ensure it is output from the performance unit. If the Performance Processor is installed on the system it should be used as the primary NMEA input."

My "best case scenario" would be to scrap everything but my three 2020 displays.  Apart from the extra power consumed from running both H2000 and H5000 I'm worried I have to bother with multiple calibration values for both H5000 and H2000 for TWD/TWA for example. But perhaps I can set H5000 to send calibrated values and set H2000 to read them with no further calibration. 

The “B&G H5000 Fastnet Interface” reversed would be ideal – but NMEA0183 to Fastnet would be fine as I can easily go from N2K to 0183. As Sailmon processors take N2K input and output Fastnet to old B&G displays – I’m looking for the exact same function but without paying for all the extra benefits of a Sailmon processor.

Tinley electronics will have options...ld consider www.aandtinstruments.com....

Started with Tinley, they are brilliant and the processor is designed to do exactly what you want, dual fuel so you don’t need to rewire everything!

brilliant support, on a lot of bigger boats now and a very viable alternative to sailmon.

I recommend asking Tinley Electronics if they have some sort of converter. They do a lot of converters NMEA/N2K/Fastnet, have a look at their site:

Thanks - I reached out to Tinley a couple of years ago,  by then they couldn't help me, I tried again last week, but still havn't had an answer.

This is exactly what A&T specialise in. Reach out to info@aandtinstruments.com or romain@aandtinstruments.com.
