Datamarine Anemometer- wind speed cups aren't moving

 

So, I save up, buy a new Raymarine Axiom+9RV? and Quantum 2 Doppler radar combo, they will be wired in next week sometime...only to take the boat out Wednesday and notice my wind direction indicator works but the speed cups are not moving.? No wind speed data. What are my options??
?
I can't seem to find just a replacement for the wind direction indicator and the anemometer at the top of the mast.? (I don't want to buy used. Don't really know what I would be getting.)
Anyone know if this - guessing - 10 plus year Datamarine display at the helm would connect to newer Raymarine atop the mast?? I am guessing, just guessing, the current signal is 0183?? I know they make a 0183 to NEMA 2000, do they make a NEMA 2000 to 0183 going the other direction? - AND OR - does my current Datamarine display connect to the current SeaTalk or RayNet?? If so, can I buy just a new arm with wind direction and speed cups?
?
The local electronics? tech is about to move the birds nest of connections of my SeaTalk from under the starboard v-birth to the storage locker up near the companion way.? So now would be the time to fix this, adding a little scope creep to my install project.
?
So, is it time to bite an even bigger bullet and replace the whole thing for a project cost of almost $2K.Please someone give me a good answer to save some dollars here!
?
My running riggers suggested I go wireless and use the new Axiom+9RV as the display.? But, that seems to be a crowded display in that scenario?? Bottom pic, Nav screen,? adding wind speed and direction too?? I just want and wish wish I could just use my existing Datamarine display at the helm and only replace what is needed topside the mast.
?
**ALSO - side note - I just bought a new Airmar P79 Transducer (internal) to give me bottom views and depth for the Axiom+9RV.? Anyone have any experience with how well that will or won't work?
?
Any and all suggestions would be appreciated !

Sorry, but there is no hope.? The connections between masthead wind sensors and displays were totally proprietary in that era.? More specifically, Database used an 8 wire connection and Raymarine (then if not now) a 5 wire connection.? Neither is NMEA 0183 or anything remotely standard.

What Jim said. You can't get the DMI masthead unit to talk to anything other than the DMI display. I replaced mine with ?Raymarine ST60 which was a great upgrade as it talks to both my Vesper system and Simrad autopilot. I preferred the hardwired sensors as I was going up the mast anyway to install the new sensor and pulling the new cable through the mast wasn't that big a deal (with help of course).

I was able to re-use the cable when I replaced an old Standard Horizon system with a new Raymarine system. I had to splice the wires at the top of the mast so that will be a weak point but it¡¯s been working ok for several years. But I think the sensors and the indicator will both have to be replaced.?

On a previous boat I had a wireless B&G wind sensor with N2K connection to a B&G Zeus. Worked great with no wires clanking in the mast. Easy to take off for mast down storage.

Verne,
?
Two years ago (summer 2023) I sent my DataMarine wind masthead unit to DMI Marine in MA.? They were able to rebuild it, and it has been working fine since.
?
They were moving locations in 2024 and it isn't clear to me if they've reopened/are still in business but probably worth a shot if you haven't checked on them.? Their website is still up with an email address.??

I have the P79 mounted in my Shamrock fishing boat, solid glass hull. It is connected to a Garmin MFD with CHIRP sonar. It works great, provides accurate depth, structure, bottom density and fish. I would say TMI for sailing. The deepest I¡¯ve been in was 90¡¯ and got good readings.?

I didn't read this thread, so maybe I'm duplicating what's already here, but here is what I know:
DMI Marine website is :
Website is still working, but not sure for how much longer. What you need is a Speed PCB for the MHU - pretty simple install if you can find one, but they don't list it on their website anymore as an available spare.
For a new MHU they want $850.00 (We sell a complete Raymarine Wind pack (Display, Masthead Unit and Mast Cable) for $899.95 so a new DMI MHU doesn't make sense. You really need to be at a boatyard with a manlift to run a new cable comfortably,? unless you are the mountaineering type and have ascender gear. Not sure if a Sabre 32 has a deck stepped mast, but if so that can be an issue running a new cable in a mast that is already stepped.

Further to my last reply and now I have a little more time, I wouldn't go wireless. We see far to many problems with both the Raymarine and B&G versions. Signals coming down from the old DMI MHU are analog voltages, nothing digital about it and the current Raymarine Short Vane MHU takes the same approach - which I like. Absolutely no compatibility between Datamarine & Raymarine though. I totally agree about keeping the wind display separate. I really don't like the presentation on an Axiom, too busy, like the B&G Triton displays and worse the B&G sailsteer overlay on the Zeus/Vulcan chartplotters which blocks out anything close to you on the screen.
The P79 50/200Khz Shoot thru the hull Txdcr will work well for traditional sonar with a transducer cable that has a DSM/CP370 style plug and then connected to the Axiom using an A80489 Adaptor cable? - as long as the hull is solid glass and not cored.
