Can You ID This ?

Its made by Airmar with a Furuno three pin plug on it......and I think it has something to do with temperature? Why it is so large is anybodys guess.
Could it possibly be differential to nmea convertor? Has ELEC-NAV J-box T80 on the plug end of cable. No other markings....

rs 232 to nmea 7 pin furuno is my guess. The 7 pin furuno has 12 volt ground and two NMEA in and out. I could be off on that but thats my best guess. I was just futsing with one of those furuno cables the other day.

Obviously is smart, and high precision...

clearly a junction box. google search for "ELEC-NAV J-box" shows a few different autopilot junction boxes matching the description. Should probably call airmar.

For something so "smart" it is being rather coy. If it doesn't do something soon I'll have its cable & bin the rest!

I don't know what the box is but Airmar make a "Furuno" high precision "smart" temp sensor that comes with furuno connections to go to the likes of an RD30.
Measures 2 places after the decimal.
If that was what it was you should have a probe in the hull somewhere tho.

I got one but it doesn't have any box like that as part of it.

*Edit* - Isn't this that same box here - answer = its an Interface box

Great detective work 2una! I guess knowing 100ths of a degree is important to someone.
In the bin it goes.

Yep, tools of the trade for pelagic fishing- alot of us also use F instead of C, 180deg differance between freezing & boiling point as opposed to 100 using Celcius,just makes the readings finer again....sometimes it matters other times it don't.
