As a follow-up, I should have noted that I have an NX2 server, but not the
so-called “black box.” The replacement Garmin masthead unit works fine on my
NX2 system.

I can’t speak to the NMEA issue. However, be advised that when
my NX2 masthead unit was damaged (by a wave, no less), Garmin replaced it
through an exchange program it had at the time. I sent in the old unit, and
they sent me what appeared to be a new one (which I still have). As I recall,
the cost of the replacement was $150. Great deal – you may want to inquire.

Subject: Stus-List Wind instrument conundrum
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,
