I have a Garmin 10 series instrument set on Water Phantom with 4 GMI 10 displays, GWS 10 wind transducer and a Garmin knot-meter/depth sounder all on a NMEA 2000 backbone which I installed about 10 years ago (?). This is connected to my Garmin 547(1?) chart plotter and this has worked fine. Now the wind transducer anemometer is 'sticking' in light air and I may need to replace the mast transducer unit entirely or at least the anemometer and wind vane. I can replace the cups and the vane for less than a boat buck and will probably try this before I consider going with Garmin's gwind replacement--the GWS 10 is no longer produced although I may be able to find one. My issue is that per Garmin phone support, if I go with the Gwind I MAY have to also go with the GND 10 black box, depending on the exact model of my GWS 10 transducer. Apparently this is used to make the Gwind talk to Nexus and may be needed to interface to my existing network. Of course I likely cannot get the exact model and serial number of my current transducer without going up the mast! My question for any NMEA experts on the list is: Can I just plug the Gwind cable into my 2000 backbone and forget about the GND Black box? Since I don't use nor plan to use any race software for my club racing, I don't see the point plus adding another box to convert something seems antithetical to the principles of NMEA 2000 which was to let compatible instruments talk to each other without such conversions IIRC. OTOH, if the GND box is necessary to get Gwind data to display on my current system, I may have to bite the bullet and do it or find another transducer that doesn't require the box which could bring a host of other problems mixing instrument manufacturers! Thanks in advance for any wisdom the list may send my way, Charlie Nelson1995 C&C 36 XL/kcbWater Phantom
