« on: May 31, 2013, 06:20:56 PM »
Hi
I have a sample here of this new 'High precission professional station'
First impressions are very impressive
its huge
its like a Davis VP
The rain gauge is like identicle to the Davis VP
Will update once I have it all setup :)

I didn't realize there was one in the works.  I guess they were tired of getting there butts kicked by Davis.

I found this picture.  Is this the right one?

yup, thats the one...upside down wind and all
see:
http://sandaysoft.com/forum/viewtopic.php?f=5&t=9939

a Davis employee has posted that its a copycat

The data protocol to the PC has changed (the HID device has changed...I have changed that to be able to open..but no data is arriving..so I need to find out what they have changed), compared to the WMR200 anyway

It appears data logging and PC interface (w/software) are included with the system so it isn't a complete Davis copy. Flipping the wind sensor around would be my first modification if I had that. Wind cups and bird feet don't mix. ;)

Think maybe that was an attempt to avoid a Davis lawsuit?

there is no software included with the sample I have
I was hoping it would work like the WMR200 for software so that its compatible
but they must have changed the data protocol a bit..I will try and find out more

There's a YouTube video of the assembly https://www.youtube.com/watch?v=4_tNJ2LEjXM. The inside and out looks like Davis. Interesting the video uploader has disabled comments. Gee I wonder why?

It will be interesting, I have zero faith that somehow OS could jump from the 200 to something functional much less a Davis competitor. The devil will be in the transmission technology, something OS hasn't exactly mastered in the past.

That was one of several thoughts I had about it.  I wonder if they'll require a datalogger or just some software like the 968 (that would be a plus).

And their sensor accuracy and reliability needs a lot of improvement.

But they're way behind Davis in product interchangeability.  They have such a large line of repeaters, accessories, consoles, remote transmitters, etc.

And if OS doesn't improve their customer service, then gold-plated stations won't improve their reputation.

Of course, the outcome remains to be seen.  Stay tuned................

it has a built in data logger
like the WMR200

the windspeed on the console updates every 2.5 seconds...which is great

the radiation sheild for the temp/hum sensor is great...best I have seen yet from OS
(the rain gauge and radiation shield are the same size as the Davis station, as is the windspeed/direction)
There is a plug socket for UV and solar...which is still to be available...and there is mount holes for those on the rain gauge...just like a Davis

(its like that add...sounds like a Golf, looks like a Golf!)

its a very positive move by OS, they have done a great job from what I can see so far...as long as they can avoid any legal copyright or similar


one problem I am having is that I have been testing the pairing of the base station to the transmitter...after 1 hour it says in the manual to reset a DIP switch on the transmitter (SW4)
but I cant get a re pair sync to work again (have reset console and transmitter)
(am doing this because the rain was dashed out on the console)

Have reset the console and the transmitter and still nada? - I'd say you just made my case. And, if the DL is even remotely like the 200 run, don't walk, away.

Many years ago I sold microfilm, Rochester Film was cheap junk, they were bought out and the product dramatically improved, but the horse was far out of the barn by then and they could have made perfect film and no one would buy it at any price, they failed not long after as I recall.

WD does not have too many problems with the WMR200 data logger
(most of the problems are actually with the supplied usb dll file and how that works)


but yeah, I am struggling to get the console to resync/pair up again, after the 1 hour period after first time
(I.e I have powered down/reset the console to test to be able to re sync up again)
looking for a master override to reset the flash memory on the console (and not a bigger hammer), LOL

ok, good news, I got it to sync up again
I had to remove the previously paired up channel (default is channel  8 )..I saw that in the manual how to do that but did not realise that is needed to reset a previously synced up pair that you wanted to re sync up
then reset the transmitter then vola
rain is showing now too on the console and working too (fast response too , like 2 second after tipping the bucket)
impressed
hopefully this thread will help someone in the future with syncing up problems
:)

OSI has the "price" reputation.

Davis
has the "quality" reputation.

Only time and product(s) will re-adjust (or not) their relative reputations.

I will see if I can get it mounted outside today
to test its durability
because chinese stainless steel in chinese made weather stations (i.e the nuts and bolts) I have found rusts badly....

I took a look at the manual last night. What I find interesting, The SIM does contain solar and UV connectors for sensors. The manual also says they're coming out with a leaf/soil station like the Davis 6345. However looking at the console screen shot of start up there doesn't look to be anything on the console for UV solar leaf wetness or soil moisture. And these options aren't mentioned anywhere else in the manual. I'm just curious as to where this data would be displayed?

After a little "diggin" I came across this website which shows system accuracy & specifications (which look GOOD):

http://corporate.oregonscientific.com/template/wmr300/WMR300_proWeatherStation.html

New TX frequency, 915MHz(USA), with supposedly greater TX distance (300m).
Outdoor sensor update interval: 2.5-20 seconds.
Outside (12 sec.) and inside (1 min.) RH accuracy 3% from 0%-to-99% RH.

Capable of handling up to 8 additional T/RH wireless sensors, but those sensors are NOT yet available.

Wireless reception working great here (I have mounted it outside now)
I am impressed with the station
The console LCD numbers font could be a little bit clearer though (they are bit 'chunky' maybe?)

How do its RH% readings compare with reality (ie: second WX system, other local stations, etc.)?

After taking another look at the manual it appears the station like other Oregon Scientific stations report wind speed in decimal numbers instead of whole numbers. How is the sensitivity of the anemometer and wind vane? Does it report at 0.1 mph or is it like the WMR200 that starts at 0.9?

I also noticed the solar panel is smaller. I'm curious as to how well it produces power?

cup sensitivity is really good for low windspeed
and the 2.5 second updates is really good too
humidity-> dew point is tracking similar as my Davis VP (mine is reading a bit high), and the same as my nearst Metar and another station

solar panel is not small

According to the web site for the WMR300 still uses just barometric pressure for the forecast. I wonder how this rates against the VP2's more sophisticated algorithm?

you cant flip it around..the skirt would then be a rain collector instead of rain deflector

Brian. I think the term "flipping" is used metaphorically to explain how the Davis anemometer might be better built or designed if the cups were on top. Personally I like the anemometers that use the cross arms like the Heath Kit wind sensors.
