I went with one of the basic Nexus start packs (image below, detail on this page

http://www.nexusmarine.se/templates/Pro ... 06D81C9%7D.

 

It does fail one of your criteria, in that it has a box about the size of a fag packet that collects the data from the masthead transducer, joins it up with the data from the through-hull transducer and flicks the whole lot on to the displays. But if I could install it... :roll: there are maybe only three or four plugs that you need to hook up anyway.

 

I did play around with the calibration a bit before realising that it worked best exactly as it was supplied.

 

As Gappy posted (somewhere) they have a practice of pulling the gear out of the box and checking that it works before they let it go out to a customer.

 

One thing you might want to bear in mind is that if in future you want to move beyond the basic functionality of that package, you will need to add a server and doing it that way will possibly work out more expensive than going straight there in the first place.

Yes NX2 simple and works! May even fit existing skin fitting!!

 

You can add on in stages, add big displays behind mast or in cockpit. Useful for more experienced sailors now that their sight is knot as good as they tell others its OK :thumbup:

 

The wind display may be connected to a wired sensor if you have one already at masthead, but the wireless is easier and keeps everything the "same" brand, so already well tried & tested.

 

Download the manuals and pre-read before buying.

KM,

 

Not sure how you're going to get it to talk to each other better if you don't go for either a standards based network or lock in with one manufatcurer.

 

NMEA data straight from the sensor (so the same data can be used in all of your instruments, plotter, laptop, etc) without any black box, is your best way to achieve that. Then you can choose any display you want.

wireless and a black box.....

2 things that make me nervous.

 

 

Kiwi Yaching have a specially designed suitcase with a FULL system so if you talk nicely to them, you could have a play / test sail.

Yes I've noticed that while many say they chat with others it appears that only happens in a very strict and often limited way. I'm thinking a single manufacturer is the way forward.

 

As the most important instrument for me is Ray, my auto driver, I may have to start there and work forward. Currently have Navman and never had an issue but it just won't talk nice to Ray. Seems to be a NZ V Aussie like situation. You can understand most of what they say but then there is the odd WTF? that just chucks it into some disarray causing random actions. My boat doesn't need more random, it can only just cope with me as it is :)

My Raymarine autohelm talks to my Navman via NMEA. Admittedly, it mostly says things like "You know what, Mr Plotter, I couldn't give a toss where you want me to go, I'm thinking of doing my own thing today.... here goes..." etc. So I have a bunch of Navman/Navstar talking to each other on proprietary Navbus and the odd man out (Ray) chipping into the conversation (mainly making idle threats) speaking NMEA.

:lol: :lol: :lol:

 

Hmmmm.... OK maybe I should revisit the current crop of stuff them. The paperwork I had shows the strings both use and only the odd one matched up. Must suss what this Navbus dodacky is. The word Proprietary can be scary these days.

 

I must admit to having a desire to have some knowledge of how things work so I can at least attempt to try and work out why I'm in a reported 90kts of wind yet fully sailed and still drifting.

As I understand it, in my limited knowledge, often the "proprietary" NMEA sentences are sent more frequently than the basic NMEA sentences, hence the statements that "we have faster data" in our equipment. Some instruments need to be told exactly what sentence to "listen for" and so ommits reading the other "say ten" sentences running around your wiring (network). So some instruments (or systems) require you to set up what NMEA sentence to "actually send" as well as the receiving instruments need to be told (setup) exactly what sentence to listen to.

 

So the GPS had to be told to send a GLL out on the Output 2 channel that was then connected to the VHF and now we have Lat & Long appearing on the VHF screen, which will be sent in the DSC distress message if activated.

E.g.

 

$GPGLL,4916.45,N,12311.12,W,225444,A,*1D

$GP = NMEA sentence from a GPS

GLL - Geographic Latitude and Longitude (hangover from Loran)

Where:

GLL Geographic position, Latitude and Longitude

4916.46,N Latitude 49 deg. 16.45 min. North

12311.12,W Longitude 123 deg. 11.12 min. West

225444 Fix taken at 22:54:44 UTC

A Data Active or V (void)

*iD checksum data

 

Note that, as of the 2.3 release of NMEA, there is a new field in the RMC sentence at the end just prior to the checksum.

 

 

Yet to do: Get the depth GRAPH on the GPS / plotter screen.

 

So perhaps your 90kts is a maximum wind speed from a recent gale when you were nice and warm. safely home fast asleep :thumbup:
