Triton wind/depth/speed/temp not showing any data on the displays

[sealegsjim]

I have two B&G triton displays, one used as wind display and one as depth/speed temp.
Both linked to a Zeus plotter via NMEA 2000
system. For some reason yesterday, both Triton screens are showing no data although they are still ‘lit up’ Does anyone have any idea where I start? Thanks

Are you getting the data on the plotter? Which would indicate the sensors are transmitting fine.

I'd start by checking and re-seating the N2K cabling between the two displays and the backbone.

No data on plotter apart from GPS

So if the plotter and the two displays, all aren't getting the DST800 data, or anything from the wind sensor, then it sounds like an issue on the NMEA 2000 backbone.

Check on the plotter to see if it can see the displays. Do you have a diagram you can post of the N2K layout? Suggest going along the backbone, start to finish checking all connections, and terminators either end, re-seat them. If that doesn't work, make the backbone smaller, moving the terminator as you go, isolating parts, to see where the fault is.

I don't have a layout diagram unfortunately. The boat is a Beneteau Oceanis 31. Does anybody out there have one or know where to get one?

You should be able to trace the N2K cabling without one. Each of displays, the plotter, the DST800 and wind device will all have connections, maybe VHF and other devices too. Follow it and you can map it out.

Should be very easy to produce one yourself.

Yup, and he can use this if he wants it looking nice. https://www.maretron.com/products/N2KBuilder.php

Thanks for that link- extremely useful bit of software.

I am told that the backbone 'end stop', sorry forget its technical name, on the B&G wind transducer can be unreliable. I was warned about this when I bought mine. If you can access a connection in the cable before it goes up the mast you could insert an end stop there to test.

I planned my instrumentation with this software, very useful. However, it does not translate exactly to the B&G kit, one or two items do not have matching male/female fittings. Just something to be aware of.

I have a similar setup but using Garmin and Airmar kit. The cable up the mast is classified as backbone rather than a drop cable and must be connected to the n2k network as such. To achieve this the Garmin wind transducer has a built in terminator.
Maybe your wind transducer isn’t doing this which might mess up things.

 

[sealegsjim]

Thank you all for the useful information. I will check each connection at the weekend.

I'd be with Vyv and separate the wind cable and put in a terminator there to eliminate that part of bus.
It's also worth pulling up the network status screen on the plotter. If it's showing errors then there's a device or cable problem. Also check device list to ensure both Tritons and sensors appear.
