Dave 11 Posted August 18, 2020 Share Posted August 18, 2020 I meant to thank you for providing the manual above, so thanks! I had a wireless NX2 system which I changed to wired earlier this year, haven't managed to hook it up yet to see if it works, and if the reprogramming of the server was successful. Hard to find support for this gear I found. If you strike problems with your testing I've still got the old wireless head, welcome to it if it's of any use. Cheers, Dave Quote Link to post Share on other sites
ballystick 72 Posted August 18, 2020 Author Share Posted August 18, 2020 Thanks Dave, it is probably a trip to nowhere trying to keep the system going as something else will fail! What was surprising was the coating of dust and dirt on the unit, a total black-out especially with it being at the top of the mast and inside a fairly sealed unit, it is a wired unit. Maybe there is some ionisation that attracts the dust?? It cleaned up well though. Quote Link to post Share on other sites
Dave 11 Posted August 18, 2020 Share Posted August 18, 2020 Yep it sure looks mint in your photos, well done on the clean up. The dust looked reminiscent of electrical bearing type stuff but you're far more technical than me! I've got a wee fella with a bucket of crap that visits all the nooks and crannies of my boat and sprays it liberally around, industrious soul is he... Quote Link to post Share on other sites
ballystick 72 Posted August 20, 2020 Author Share Posted August 20, 2020 I connected the unit up and used a fan to spin the impellor. Seemed to respond to speed and direction but unsure of the quality of the signal. Periodically there is a packet of pulses that come through, one is direction and the other speed. Still a bit of playing to be done. Quote Link to post Share on other sites
kiwi_jon 26 Posted August 20, 2020 Share Posted August 20, 2020 What you are looking at is rs485 serial datagrams at a 9600 baud rate that contain wind speed and direction information. It is the protocol that Nexus use on the NEXUS/instrument data bus. The original NX2 wind transducers like the one I have just replaced connect to the wind port on the server and data encoding is done in the server whereas with yours and my new transducer the data is encoded and packaged in the head unit and the cable connects directly to the NEXUS/instrument bus. When I pulled my old transducer apart the front bearing was totally flogged out and rusted solid. The shaft was well worn and there was rusty residue throughout the unit and on the electronics. Unfortunately my new transducer doesn't work either. I think I have cable damage inside the mast so the rig is now ready to whip out next week. The riggers are going to replace my rod rigging and 32 year old rigging screws at the same time as I do the electrical work on the mast. Replacing my wind gear has turned into an expensive excercise. 1 Quote Link to post Share on other sites
Island Time 1,234 Posted August 20, 2020 Share Posted August 20, 2020 Might be a good time to update it. $2600 for a B&G wireless (mast unit, rest is wired) Triton 2 depth/speed/wind pack. Comes with masthead unit, receiver, Triton 2 display, N2k starter kit, DST (depth speed temp) thru hull. 1 3 Quote Link to post Share on other sites

IT supplied a B&G system, and it's great. Super easy to read. Plenty of information / display options. 1 Quote Link to post Share on other sites
ballystick 72 Posted August 20, 2020 Author Share Posted August 20, 2020 Yes, the inevitable system replacement is on the cards. I like the pricing of the B&G these days and it seems that the quality and reliability has been retained with the budget range. Quote Link to post Share on other sites
Dave 11 Posted August 21, 2020 Share Posted August 21, 2020 Has anyone got experience with the NX starter system with the WSI box and no server? I've gone with a wired wind transducer but didn't get the brief on where to attach the cable. The WSI box is full so I'm assuming it goes directly to the back of the instrument itself, can anyone clarify please? Thanks Quote Link to post Share on other sites

Thanks You can't plug a wired wind into a standard wsi box as its always looking for a wireless masthead unit signal the only way is to get the wsi reprogrammed so the wireless wind is turned off the mast cable is then wired into the network port piggyback colour for colour 1 Quote Link to post Share on other sites
Dave 11 Posted August 22, 2020 Share Posted August 22, 2020 You Sir, are a legend. Thanks for that, my WSI box has been reprogrammed so I'll hook it all up and see what happens. Be nice to turn that ornament on the top of my mast into something a bit more useful. Final old Nexus question: Is there any way to output the data to a laptop? I'd like to have a play with OpenCPN tactics and build some polars. The interwebs would suggest not... Cheers and thanks again. Quote Link to post Share on other sites

If it is an original Nexus NX2 wired wind transducer then it is going to require a server to encode the pulse outputs. If it is a Garmin wired wind transducer then, yes, it connects directly to the NEXUS/instrument bus. I am not sure what color coding Garmin use in their cable. I have a short adapter cable that converts the Garmin Gwind cable to Nexus mast cable. Quote Link to post Share on other sites

Dave 11 Posted August 22, 2020 Share Posted August 22, 2020 That's grand thanks. It's definitely not NX2 so hopefully it should all work... Cheers Quote Link to post Share on other sites

It doesn't matter with NX both the old and new masthead units work but either way you need to reprogrammed the wsi box. Like wise if you plugged a wireless wind into NX2 server the server had to be programmed to look for the wsi box. Quote Link to post Share on other sites
