Tazzy Devil 18 Posted October 8, 2018 Share Posted October 8, 2018 Anyone had any issues calibrating using triton 2 displays? I have a Garmin wind sensor and heading sensor both N2K but for whatever reason my Triton2 displays won't store calibration offsets. overseas reviews say the should work together fine. All the literature says N2K is N2K so was wondering if this was a b and g thing or am I missing something? Try to store offsets (heading and MHU) and the displays think about it for a bit then say failed storing offsets. Will call B and G tomorrow and Garmin but just wondering if anyone else had these issues - it could be a defective unit somewhere on the network perhaps? Quote Link to post Share on other sites
Island Time 1,239 Posted October 8, 2018 Share Posted October 8, 2018 N2k sentences are (should be!) standard. Calibration and how its done is not. Different manufacturers systems do not always play nice. Yes, the devices should talk, but they may not calibrate. The best devices can be calibrated at source (the transducer or whatever) so they don't put "false" info on the bus. Quote Link to post Share on other sites
Tazzy Devil 18 Posted October 8, 2018 Author Share Posted October 8, 2018 Data is all coming through but, yeah offsets aren't storing anywhere. Will see if there is a trick to get it to work a PBO article says it should be no issue. If not I'll try and borrow a Garmin plotter I guess to store the offsets in the TDX (as thats where Garmin says it is stored). Quote Link to post Share on other sites
mattm 98 Posted October 8, 2018 Share Posted October 8, 2018 IT’s onto it, as usual. You can’t store data to a Garmin mhu with a BnG display, you will need a Garmin display. The output data is all nmea2000 and shareable, but whatever sentence is sent for calibration will be somewhat more proprietary. Have you installed a lone Garmin mhu on an otherwise BnG system?

Tazzy Devil 18 Posted October 8, 2018 Author Share Posted October 8, 2018 Yeah lone Garmin MHU on. B and G system as the gwind was the only option that fitted my network plan. I will try to borrow a unit to do the calibration, don’t want to buy one if I can help It. Quote Link to post Share on other sites
Island Time 1,239 Posted October 8, 2018 Share Posted October 8, 2018 Did I forget to say I'm a B&G certified tech, and I do this for a living? Please elaborate on why the B&G Masthead unit was not suitable, either the wired or wireless one. Quote Link to post Share on other sites
Tazzy Devil 18 Posted October 8, 2018 Author Share Posted October 8, 2018 Basically the mast was too tall for wireless and I wanted to terminate the backbone in the mast display box so couldn’t have it terminating at the Masthead. If it hadn’t been for the PBO article claiming it would work I would have gone all b and g drilled more holes in the mast etc. it’s done now though. I have a plan now so will try to sort it after checking in with Garmin. Thanks heaps! Quote Link to post Share on other sites
Island Time 1,239 Posted October 9, 2018 Share Posted October 9, 2018 Wireless 320 will do 25m. Whats the boat? If there is a terminator in the mast display box, isn't it pretty easy to remove it, and plug in a mast head cable? The B&G masthead units have a terminator in them, and are therefore normally one end of the bus... Quote Link to post Share on other sites
Tazzy Devil 18 Posted October 9, 2018 Author Share Posted October 9, 2018 Navico advised against going wireless as the mast is 15.6m and the receiver couldn't easily mount on deck as it's all a working surface - when I spoke to them. The plan was to avoid having to run the backbone into and out of the mast display bracket as that would involve two splices and more holes in the mast plus fishing wire through - doable but the Garmin option was easier as I could hook the blackbox to a drop off the backbone at the mast base and leave only the one cable (backbone) going into the mast bracket. Only have to manually enter the MHU offset (which I have the number - 2 degrees) so have arranged to borrow a Garmin unit for the 10 minutes that will take. Stored in unit so once it's done it's done. As an aside the B & G triton 2 and Vulcan setup I have installed is pretty amazing for an entry level set-up, everything else is working sweet with very visible displays and more options than I can use. very happy with it.

Island Time 1,239 Posted October 9, 2018 Share Posted October 9, 2018 Hah, you spoke with the wrong person at Navico! A 16m mast won’t be an issue. The unit spec is 25m, approx, depending on receiver location, Hull material if inside etc. These are new units, and not everyone has done the training on them yet. Good splices on n2k cable wont be a problem. I’m not sure that a borrowed Garmin unit will make any difference. The calibration still has to be stored, and it won’t be in Navico format.

Tazzy Devil 18 Posted October 9, 2018 Author Share Posted October 9, 2018 According to Garmin calibration is received and stored in the black box then corrected data is output in n2k- will see what happens, failing that a trip up the mast and tweak is in order.

Tazzy Devil 18 Posted October 9, 2018 Author Share Posted October 9, 2018 Then get a b and g wireless unit when the gwind is up for replacement Quote Link to post Share on other sites
Island Time 1,239 Posted October 9, 2018 Share Posted October 9, 2018 Ok, if your keeping that device, that should work, provided you manually select the correct source for the data (under network, sources, in the setup menu on the Mfd). Quote Link to post Share on other sites
Gappy 9 Posted October 9, 2018 Share Posted October 9, 2018 The Garmin Gwind still runs on Nexus Protocol and uses a GND10 Black Box to convert from Nexus to NMEA200 to then talk to the Garmin units. The masthead units are pre calibrated ex factory and you can only adjust this through Nexus race software and a laptop there is no provision for adjust them on a display you uses to be able to with the old units but not the Network units. You can adjust offset of the Masthead bracket but that's it. Quote Link to post Share on other sites
Tazzy Devil 18 Posted October 9, 2018 Author Share Posted October 9, 2018 Thanks, It’s just the mhu offset I want to adjust. Quote Link to post Share on other sites

Not only can I set the mast offset, I can auto calibrate, downwind shear compensate, build polars and so much more. Way cool. Anyway initial problem is resolved, now to build some polars for the boat! No idea why Garmin doesn't market this. Quote Link to post Share on other sites
