In Topic: Connecting TackTick Triducer to Nexus NX2 network - help!

23 June 2015 - 10:57 PM

PROBLEM SOLVED it turned out that the tacktick dst800 triducer was the faulty part of previpous Tacktick instrument system,
I had been going to replace anyway with two separate AIRMAR S & D transducers tthat came in NX2 cruise pack. Obviously this needed a haul out and relaunch plus one or two hours work in the yard - not cheap if done in a hurry.
Realised I could buy and fit a new Garmin smart DST800 nmea2k and calibrate via GNX120 display. Cost £240 but fit and setup went
easily and quickly. Sometimes NMEA 2000 really is plug and play!

PS: Does anybody need a brand new airmar Log/temp 52mm transducer w/8m cable
.and a Depth 52mm transducer w/8m cable (located UK)

1. Expedition (if you have a copy) has supported transfer of route waypoints to a NX2 system and storage in a NX2 server for several years. We need a NX2  navigator display as well as a server. The menu is MARKS/EXPORT/NASTRUMENTS.

This also works for some other systems including NMEA2000 systems that support PGN 12


see help file


Sends mark and course information to instruments (NMEA 0183, NMEA 2000, Nexus FDX etc).

Note that PGN 129285 must be enabled to send for NMEA 2000.

Also available from the application menu.



Hopefully this will soon be extended to support PGN130074 for B&G MFDs.


2. The Expedition system will also now read and import  a cowes week format sms txt file a build a route from it in a few seconds.


3, Alternatively, given a fixed set of race can waypoints, it is possible to program a macro in excel or anorther language 

to read in a set of waypoint names , and output coures and bearing per leg to a pc screen and output a .gpx file with the route to Expedition or a similar program.


Hope this helps

I stand corrected! 

Will try the 19200 option (assuming I can get nexus nx2 to write at that rate).

replying to myself:


I bounght two GNX120s to replace the Tacktick mast displays on my J97.


you cannot use a GND 21 to program the display on  a GNX120, nor to convert NMEA 0183 sentences to NMEA 2000 pgns (pity)


- you need to buy an Actisense NGW-1 or something similar for the conversion to 2000  from 0183 if you need to.


The main problems here is that

tho Actisence are very reluctant to tell you so,  they never got round to making the ISO protocol converter work faster than the standard 4800 baud! 1 to 2 seconds delay.Needs to be

9600 or 19200 baud.


- if you have Nexus stuff you might buy a Garmin GND10 but there are lots of restrictions as to what it will and wont do. It seems it wont actually work with a Nexus 

server btw, at least for now.


The GNX120s are nice!
