NMEA 2000 issue

[macca499]

That’s very kind thanks Martin but I’m in NI, I’ll nip over to the chandlers tomorrow and grab a cable and Tee, will be good to have handy for future anyway, going to pull out all trunking today then get some photos and sketch it up, one thing dawned on me last night after re-reading post above - it appears that the dst is plugged into the end of a tee rather than into the top of a dedicated tee unless this is a backbone link cable and there is another leg of the backbone I haven’t found, I had a company install an ais800 when I bought the boat which is beside this part of the backbone, other than that it would have been how it was when it left the factory.

Ok last post until I can provide some solid sketches or photos, I unplugged the cable mentioned above and I lose wind and airmar dst so I must have a third section of backbone somewhere for these two devices presumably with the second terminator on the end

So after all that it was indeed a faulty transducer, an expensive item but happy it is working and have the benefit of Bluetooth with the newer unit. Just want to say a massive thanks again to the forum as i now have an understanding of another system on my boat thanks to your knowledge and kindness to share. I do indeed have three parts of the NMEA backbone with a terminator at each end and also a garmin network input somewhere for the plotter and radar.

well done!
struggling to see the point of broadcasting bluetooth SOG depth and temp but that's probably me in the Med where if you're under 4-5m depth you start panicking...
may I ask what's the healing gauge on this AIRMAR BT mobile app? Do they have an at least 6DOF sensor that feeds it or what?

I think the Bluetooth is more for calibration and setup as it drops out when you get only a few metres away from the transducer, not sure on the heel sensor - I do have this as a parameter on my plotter screen but never thought to check the source for the data

The heel sensor is built into the DST810 vas

thanks Paul, wasn't aware, and obvs needs to configure the deadrise of each hull else you'll be healing in your mooring

There isn't one on my DST200...
would be better if the guys/gals in AIRMAR spent some time to figure out how to make the Temp work reliably for more than a couple of seasons tbh

Yes, i agree.

You calibrate the deadrise and offset with the App.
