Title: Wiring RM Young - HD model 05108 to Davis universal anemometer interface
Post by: jconley2 on October 15, 2019, 10:59:37 PM
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?

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

Thanks in advance!

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.

https://video.nest.com/live/bxHi99uZFx (https://video.nest.com/live/bxHi99uZFx)

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!

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.

Post by: twcmaster on October 18, 2019, 04:18:46 PM
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.

Post by: jconley2 on October 18, 2019, 04:25:43 PM
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.

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)

(http://rogerscityweather.com/weatherdata/Davis-Young-MPH.png)

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

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

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!

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?

Standard prop is 18 cm DIA x 30 cm PITCH. HD prop is 18 cm DIA x 50 cm PITCH.

Good question; I had wondered the same and awaiting word from RMY.

jconly:
Look on eBay, they often have props also on sale there, and I don't recall any of them being that much, even with shipping.

Young is a good company and makes quality products, and I've bought some replacement parts from them, generally well priced.  Some Met One stuff has been eye blinkingly high, as well as some stuff from Campbell, but then other things Campbell has are reasonable.  I guess you can't second guess what it costs to make stuff.

Let us know.  Dale

I just got my setup working! I hooked up only the wind speed for now, but everything is looking good so far at low speeds. I am really looking to test higher speeds, but of course winds are forecast to be fairly light over the next couple days. The good news is the Young wind monitor and the Davis console attached wirelessly to the universal anemometer interface are very much in sync. I am now curious to see how the Davis console does with wind gusts now that they are coming from the same instrument.

It is really nice to see the young monitor, and the two Davis consoles (one hooked up to a 6410 on the same pole as the 05106 and the other hooked up to the universal anemometer interface) dance in unison. I will share further results here when we get some higher speeds.

Dale -- Good idea, but no props are currently available (that I could find.) No worries though, I've one coming directly from RMY.

Twcmaster -- Great to hear! Saw that on your live video stream just now. Ordered a new prop yesterday, so my 05108 + Davis setup should report accurately very soon.
Btw, re: benefits of 05108 (HD) prop -- per RMY, "The HD’s are built for extreme, constant, high wind conditions.  Since the different pitch allows the prop to spin at a slower RPM for a given speed it is less stressful to the prop and bearings." That makes total sense and is good engineering on their part. Where I am in Vermont I won't have constant wind, so even with the standard propeller the ceramic bearings should not wear out any time soon.

Good news! I swapped out the propeller earlier this week and immediately noticed improved wind speed measurements. Feels good to finally have accurate wind reports. BIG thank you to everyone who helped bring this to resolution! :grin: Couldn't have done it without you!

I'm Curious how the Davis and Young peak wind speeds are comparing after you made the change. Does one always seem to be higher still?

Whoops, I really dropped the ball on following up on this thread. The overall storm peak gust speeds at high (50-70 mph) speeds are very close with the Young and the Davis. If one unit broke, I would feel very confident in the other even if that other is the Davis.

Things weren't always that way (the Davis used to always be ~4 mph greater when I tested this setup under different conditions a while back). I am not sure exactly what I could have been dong wrong, but that was also with an older 6410, so maybe that was the issue. Regardless, whatever I did, both are very well in sync right now, although not always exact.

I am also comparing the gusts from the RM Young Wind Monitor displayed on the RM Young display updated once per second and the Davis console through the anemometer interface. The Young will definitely catch gusts that the Davis won't, but overall it doesn't seem to be too bad.

Thanks for the update! I had tried a refurbished Young 05103 a few years back with a universal anemometer kit device from Davis. I ran a comparison with the Young and a Davis 6410. They were mounted close to each other on the same pole. I had a similar issue where the peak gusts were almost always 1-4 mph higher on the 6410, sometimes more. I was tired of the bearings wearing out on the 6410 and wanted to try something different. I even tried a NRG 40C and that worked well, but would ice up really easy with any sort of freezing drizzle. How well does the Young 05103 perform in freezing rain/drizzle?

A bunch of years back,  I purchased a 05106 off ebay and did the same with not great results. I am not sure if it was the unit or I just didn't know what the heck I was doing (have learned quite a bit since then).

I go through a new 6410 every 2 years like clockwork. The bearings sieze up and the cups won't spin at all. I was lucky enough to get the new RMY 05106 http://www.youngusa.com/news/marinewindmonitorupgrade.html which has ceramic bearings like the HD's have so hopefully that will maximize my time between service since I have to pay a roofer to go up there every time I need something done.

I have not had an issue with any type of frozen precip yet, but I have really not had a good ice storm to test it yet. The wind in the winter never slows down enough so the propeller would need some really thick rime to make an impact which I just haven't seen yet. We ironically had more frozen precip in May this year than February in this part of NY. If we get a good ice storm in the future, I will try and update this thread.  Of course, they also sell an Alpine version with black paint that can absorb heat a little better, but not sure how much better that would actually be in real life.

I have some 5103s around here that have aged to a decade or more.  Of course we don't have constant gales and thank goodness no salt spray to deal with.

Never had one give me trouble (yet), but since they are way up on a tower at just above tree tops, they are hard to get to.  The guys I used to have climb (ham radio guys) have all aged along with me.  A young dude who does tree work climbed it like a scared squirrel, but he moved and I haven't been able to get ahold of him lately.  The need to work on these things is always on my mind.  I look at the antennas and wind and weather stuff on Navy ships and wonder what poor guy gets to go up there to retrieve and fix stuff, especially in heavier weather.

I have had a 5103 get weathered up twice.  both times were with heavy wet snow with no wind.  And of course the cold afterwards made it freeze solid for a day or two until the sun thawed it enough to drop off.

I can't find it right now but a few years ago I took some close ups of my 'test' 5103 on the back porch with ice hanging off the prop and body.  Was sort of neat.  The fortunate thing was it was when there was a slight breeze and the prop kept rotating, and the centrifugal force kept spinning the water off, so there were 2 to 3" ice icicles off radially all the way around.   I'm sure the imbalance caused errors in wind speed, but my hobby doesn't demand incredibly accurate results, just the fun of doing it.  If I find the pix, I'll send them on.  By the way, the same thing happened to a Rainwise wind sensor too, with the icicles hanging off it.  When the heavy wet snow came down the RainWise was froze up for awhile too.  The record looked like it went dead calm.  The worse one for freezing up with snow is the Vaisala WXT520, which even with the heater, has a bit of a time getting the frozen precip off the stainless steel dome.  I hear the RM Young version of the ultrasonic is much better.

The 05108-45 Alpine in all black also has a special ice resistant coating which may help. However, it uses the 05108 Heavy Duty propeller which has a different pitch and is not compatible with the Davis universal anemometer kit, so will under report wind speed. However, swap it with the standard prop (used on 05103) and that will resolve the issue.

The 05108-45 is the one I am leaning toward. It actually is compatible with the Davis universal anemometer kit. Instead of shunting the pin for the 05103, leave the pin in the other position then enter the correct calibration number in the Vue console, 1666 for the 05108-45.

Glad that's a configurable option for Vantage Vue owners. Thanks for sharing. Unfortunately, for Vantage Pro 2 and WeatherLink Live customers, that is not an option in the configurable settings, so using the standard prop is the only way to go if using the 05108 Heavy Duty or 05108-45 Alpine with those Davis stations. That said, the 05106 Marine uses the standard prop by default, so no swap needed.

This information is on page 2 of the 05108-45 manual, under calibration formulas. The number you want is the WIND SPEED vs OUTPUT FREQUENCY in m/s, 0.1666. You then take this number and multiply it by 1000 per the Davis universal anemometer manual, and enter it in the Vue console.

I spoke with a person at RM Young asking about how well the 05108-45 has been performing in the field, especially in harsh icing conditions. He said that there are two at the top of Mt. Everest and they have been performing well in those harsh conditions. I figured if they can work up there, they should work anywhere! Here is an article on that weather station. https://www.washingtonpost.com/weather/2019/12/13/worlds-highest-weather-stations-reveal-intense-sunshine-may-be-melting-ice-mount-everest/ (https://www.washingtonpost.com/weather/2019/12/13/worlds-highest-weather-stations-reveal-intense-sunshine-may-be-melting-ice-mount-everest/)

Just an update, I have successfully interfaced the 05108-45 Alpine with the Davis universal anemometer kit. I noticed a small typo from a previous post of mine, the calibration number entered in the Davis Vue console should be 166.6 not 1666. Since the Vue does not allow one to enter tenths, I rounded up to 167 for the calibration number.
