I've a Vantage Pro2 Plus, universal anemometer interface (discontinued), and anemometer transmitter kit that I would like to use with my RM Young wind monitor HD (model 05108). Does anyone have experience doing this? Model 05108 is very similar to model 05103 (which is referenced in the universal anemometer interface instructions), but wiring it is different. The 05108 does not have a junction box on the side like the 05103 does, so not sure which wires go together. Could anyone guide me through it?

Universal anemometer interface instructions: http://www.davisnet.com/product_documents/weather/manuals/07395-231_IM_06336.pdf

RM Young model 05108 manual: http://www.youngusa.com/Manuals/05108-90(B).pdf

Thanks in advance!
Jim

Hi Jim,

Quick Note: If someone else has more experience with this, please chime in as I am far from an expert, and this info is from years ago, but I do want to share the info that I do have.

I also have a Davis Universal Anemometer Interface and I hooked it up to a 05106 Marine Monitor a few years back. While I believe the 05106 is supposed to be wired more like a 05103, it has 6 wires like the 05108 versus the 5 wires for the 05103. It also has a pigtail instead of a junction box like the 05018, so hopefully the wires are the same.

This is what I have in my notes I took back then as far as which wire to connect to what.  This is just something I jotted down. While I did get the Young wind speed and direction up and running years ago on a Davis Console, I never got to the point where I was able to fully compare the setup to a Davis 6410 anemometer like I intended to make sure everything was actually set up properly.

05106------Davis
Blue--------Black
Red---------Blue
White-------Yellow
Green-------Green
Black--------Red
Ground------Not Used

I do intend to try and get my setup up and running this winter, but I have been so busy I am surprised I have even had time to reply to this, so who knows when that will be. I now also have a Young 32500 compass/serial interface in my setup that I didn't have back then that complicates things a bit, but I will share what I find when I get around to setting it up.

If you get it working or find any good info, I would appreciate if you could share as well.

Good luck!

P.S The thing that held me back from getting this up and working is that I bought a Young wind monitor. Put the Davis on the same pole mm apart from the vanes hitting each other. This allows me to compare the 2 readings and I really enjoy being able to watch 1 second updates during big wind events. Every expensive, but has been well worth the $$ for me. Here is my live setup. Expecting a Nor 'easter tomorrow and probably even stronger winds Thursday:

From looking at the 05103 diagram, the only difference that I can see is that on the 05108 the "Wind Speed Reference" is BLUE, where on the 05103 both the direction and speed "references" (common/ground) are both black.

The 05103 diagram has a jumper that ties both references together. It looks like yours has a "J1" for the same purpose.

I'll attach the table  [ You are not allowed to view attachments ]  that I made when I installed my Wind Monitor Jr. (same pinout as the 05103, the vane is just shorter than the standard one)

Thanks for sharing! Your info matches my table exactly which makes me feel more confident about the whole setup! I may have to try and find some time to get this figured out sooner than later.

It worked! I am receiving both wind speed and direction data. Strangely though, it seems like wind speed is under reporting. It was breezy today (nor'easter on the way) here in southern Vermont, but the strongest wind measured was 14 mph -- it seemed stronger than that. Curious, did you have the same experience?

Before final installation on the roof, I used my Stihl Kombi leaf blower to test it out (haha!) -- peak gust was only 26 mph. So, something seems off...

Thank you for taking the time to post; I really do appreciate it!

Jim

Thanks, Greg! I compared the wiring diagram of the 05103 and 05108 (mine) and the "J1" jumper is referenced, but does not appear to be connected on the 05108. Also, there's a reference in the 05103 diagram that the "J1" may need to be cut/disconnected, but that reference is omitted in the 05108 diagram leading me to believe it's not connected, possibly since there's no junction box interface on the side.

The wiring configuration you both shared is working, but it appears that wind speed is under reporting. See my post above. Not sure what could be the culprit. Any thoughts?

Thank you for all your help!

Yes, I did notice that the speeds seemed what I thought were off. I don't remember exactly what I thought off was, but I do remember being disappointed that the Young hooked up through one Davis Console did not match up with a 6410 hooked up through wireless and side by side with another console. For the record, this was a very anecdotal observation and I was mainly comparing only the gust speeds, but it did warrant me calling Davis tech support (weren't helpful) and eventually buying a brand new 05106 (the one I tested this all with was the first one I bought used off e-bay) and wind tracker display.

I must add though that even with the current setup I have now (the new 05106, and I have been through multiple 6410's), the Young gusts are almost always lower. Not sure if this is due to overspin I have read about on the Davis. At low speeds <15-20mph, the two gusts generally seem to match within 1 mph. Once gusts get above 25-30mph, the Young is generally about 4 mph less than the Davis.

I am just trying to share this info to be transparent on what I have done, but I am not sure there was necessarily an issue, it definitely could have been one of my variables.

The good news is once I can get mine set up (which now I am itching to do more than any recent time), with all the time I have spent looking at the two displays live and remotely, I'll know right away if there is really a problem when comparing the Young to my 6410.

Back to your setup,  can you try the leaf blower on the Davis anemometer on the same setting and see what you get compared to the 26mph the young produced?. Do you have a clear fetch? Or are there trees around that can hamper the wind speeds? Is the wind direction matching (due south is where the pigtail comes out of the base). Just thinking out loud of some things I would try.

Anecdotal, yes, but still valuable info, I think. Thanks for sharing those details.

Yep, once the storm passes I'll blast the Davis anemometer with the leaf blower. :) Although not scientific, it is kinda fun and will be a good litmus test as to whether something is truly amiss with the RM Young setup.

There are trees nearby, which will affect measurements. The unit is mounted 4 feet above the roof apex. Will check on the location of the pigtail. The guys who installed it were meticulous in properly calibrating the wind direction to ensure accuracy, but doesn't hurt to re-check.

Confirmed wind cup type is "Other" on the console. And, on Weatherlink Live console (which I set up this evening), is configured to 3rd party anemometer type.

I would check to see if when the propeller is facing the direcion of where the pigtail protrudes, that the console is showing a 180 degree due south reading. If this is wrong, there could definitely be an issue with the wiring of it all.

Confirmed the pigtail protrudes 180 degrees south. Wind direction readings are accurate, so all good there.

Wind speed is the problem child. I did the same leaf blower "test" on the Davis anemometer -- 93 mph (Young was 26 mph.)

Do you recall having to cut the "J1" jumper cable in your 05106? The wiring diagram on my unit did not show it attached (probably since there's no junction box like with the 05103.) I'm wondering if the jumper may be the culprit.

Ugh, that is a huge difference.

I do remember cutting the jumper wire on my Young Jr. (04101) model, but that is when I abandoned the idea of using that model and bought the 05106 on e-bay and tried that instead. Where is the jumper on your model? Do you have to remove the pigtail bracket on the unit? The 04101 had a junction box.

It's in the anemometer shaft (according to the wiring diagram.) I'd have to go "under the hood." Did you have a jumper to cut with the marine 05106? The wiring diagrams of the 05106 and 05108 (mine) appear identical.

I compared the wiring diagram of the 05103 and 05108 (mine), the "J1" jumper is referenced on the 05108, but does not appear to be connected. Also, there's a reference in the 05103 diagram that the "J1" may need to be cut/disconnected, but that reference is omitted in the 05108 diagram leading me to believe it's not connected, possibly since there's no junction box interface on the side.

Hmm, I never removed the pigtail connector to look at the jumpers when I was doing this, but then again, maybe that was the problem. It definitely looks like it is not connected in the diagram though, but I am no expert on reading these

I did remove the pigtail connector at a later time just to see what was in there, but I did not have this project on my mind at all, so all I can say is I remember it was very easy to do (easier than the junction box, less screws, lol) from what I remember and I wasn't worried about messing anything up.

See this thread: it may or may not be helpful.

https://www.wxforum.net/index.php?topic=31681.msg317736#msg317736

I watch both my Davis and RMY on adjacent consoles. I also have a wind plot showing the speed data (and the nearby Marina, ignore that for now)



See my wind page showing the (almost) real time comparison.

http://rogerscityweather.com/wxDavisYoung.php

If you have access to an oscilloscope, maybe observing the speed signal waveform coming from the RMY might be a good check.

I may drop a message to RM Young to see if they may be able to help.

Ok, please let me know if you find anything out. I sent them a sales question once and they didn't even write me back, so I hope you have better luck than I did.

Very nice, Greg! Looks like the RMY and Davis are closely aligned. And, great website too.

Good idea on the oscilloscope. Now to find someone who has one...

Thank you too, I definitely have renewed excitement to get this figured out, and more heads together is always better than one.

And thank you too Greg! Your insight shared here as well as your website have been an invaluable resource to me on this topic and many others over the years!

Found the source of the discrepancy! RM Young sales tech responded with:

"Jumper J1 just gives you separate references and it is already out (cut) on the 05108.  The difference is probably the propeller as it is very different from the 05103 prop.  The 05103 propeller is 29.4 cm of air passage per revolution, the 05108 is 50 cm so it will report slower for a given wind speed if that is not taken into account."

In looking at the manuals...

Model 05108: mph = 0.3726 x Hz
Model 05103 and 05106:  mph = 0.2192 x Hz

So, I've two options:

Option #1: Build a custom-made universal anemometer interface for my RMY 05108 to take that conversion formula into account.

Option #2: Replace current model 05108 propeller with model 05103 propeller. RMY confirmed my model is interoperable with that prop. It's $40 + shipping

The latter is probably the easiest and most cost-effective solution. :)

Thanks for sharing! I still haven't had a chance to open up my old 05106, but I did notice there were more screws on there than I thought there were.

There is an option in the console to change the calibration number. I believe it is referenced in the manual, but I figured I should mention it. Not sure if that can be helpful if RM Young can provide the values needed to plug into the formulas.

Also, #2 is probably the best option,  but the new 05106 now has ceramic bearings which is one of the main benefits of the 05108. Not sure if yours is returnable, but figured I would mention that as another possible option.

That is definitely interesting about the propellers as they are all listed as the same size on the website, so I guess that means they are a slightly different shape?

Thanks for sharing and keep us updated!

Interesting. I've the new WeatherLink Live hub from Davis, but didn't see an option to change the conversion. Also couldn't find it on the Vantage Pro2 console.

Prop must be a different size or shape, but not sure since I couldn't find measurements. Per RMY, the Marine model (05106) is the 05108 with the 05103 prop. So, I'll soon have a de facto 05106 with the 05108 badge. :)

Will keep you posted!

Re: Wiring RM Young - HD model 05108 to Davis universal anemometer interface

Found the source of my discrepancy! RM Young sales tech responded with:

"Jumper J1 just gives you separate references and it is already out (cut) on the 05108.  The difference is probably the propeller as it is very different from the 05103 prop.  The 05103 propeller is 29.4 cm of air passage per revolution, the 05108 is 50 cm so it will report slower for a given wind speed if that is not taken into account."

In looking at the manuals...

Model 05108: mph = 0.3726 x Hz
Model 05103 and 05106:  mph = 0.2192 x Hz

So, I've two options:

Option #1: Build a custom-made universal anemometer interface for my RMY 05108 to take that conversion formula into account.

Option #2: Replace current model 05108 propeller with model 05103 propeller. RMY confirmed my model is interoperable with that prop. It's $40 + shipping

The latter is probably the easiest and most cost-effective solution. :)

Thanks for sharing! I still haven't had a chance to open up my old 05106, but I did notice there were more screws on there than I thought there were.

There is an option in the console to change the calibration number. I believe it is referenced in the manual, but I figured I should mention it. Not sure if that can be helpful if RM Young can provide the values needed to plug into the formulas.

Also, #2 is probably the best option,  but the new 05106 now has ceramic bearings which is one of the main benefits of the 05108. Not sure if yours is returnable, but figured I would mention that as another possible option.

That is definitely interesting about the propellers as they are all listed as the same size on the website, so I guess that means they are a slightly different shape?

I can't believe I never noticed the props were different, but looking at the website, they clearly are. Do you have any thoughts on what the advantages of the different props are?
