Title: Build Your Own Davis Console Datalogger
Post by: DeKay on November 13, 2011, 01:00:39 AM
More good news.

Way back when I posted how to interface to the Davis console (http://www.wxforum.net/index.php?topic=10315.0) without having to buy Weatherlink and the dongle that came with it.  The limitation of that solution was that you didn't get data logger capabilities.  There was no way to get data from the console unless a computer was hooked up to it at all times.

Until now.

We have wxtech to thank for being crazy enough to unpot his logger and reveal what lurked beneath (http://www.wxforum.net/index.php?topic=11675.msg112519#msg112519).  Since then I've been itching to see if I could build a DIY version, but my time has been very short.  That changed this weekend, and I have been able to successfully get something working.  More details can be found in my blog (http://madscientistlabs.blogspot.com/), specifically this post (http://madscientistlabs.blogspot.com/2011/10/build-your-own-davis-console-datalogger.html).

You can put one together for around $5 - $10 depending on what you have at hand.  I'd say that just about anyone who knows which end of a soldering iron is hot could put one together.  To add a bit of suspense to the whole thing, the memory chip I am using has four times the capacity of the Davis version (4 MBit vs 1 MBit).  I don't know if the console will actually make use of that extra memory or not, but I was willing to pay the extra 43 cents to find out.  I'll know in a few days and will let everyone else know.

Good luck should you try to build one yourself.  I'll keep an eye on this thread and the comments on my blog should anybody need a hand.

Here's a teaser.  And no, I do not own The Real McCoy.

Once upon a time there was a company called BlueWave who made a clone logger, that had double the standard memory  ;)

But there is NOTHING stopping an individual from making their own.  And there is some doubt whether they can be commerically sold or not (Magnusson-Moss Act etc.)

Hopefully Dekay will let us know shortly whether his logger supports double the mem.

Dekay, would you agree that this schematic agrees with your connections? I'm using a 3.3V FTDI cable attached to the 6 pin header.

And here is a layout (done in less than 1/2 an hour!) of the above. I have the design files and can make these for anyone and ship at cost plus a little for my time... (say about £40)

Sadly, C2520 is correct.  I topped out at 2560 records, which is the max capacity of the Davis product.  The BlueWave guys must have pulled an interesting trick to get more capacity.  Anybody know if they might have hacked the firmware to do so?  That would explain Davis coming down on them.  Oh well, the gamble was worth 43 cents.

Nice!  And fast!  Looks good to me.

Would you consider providing the design files under some kind of open license like the Creative Commons Attribution Share-Alike license so that people could spin their own boards?  That would very much be in keeping with the spirit of this whole thing, and nothing would stop you from providing a service to people for ready-built units.  Think Arduino (http://www.arduino.cc/en/Main/FAQ).

No offense intended... Looks like the raw output of an autorouter. I would have at least tweaked it to eliminate the trace going through vias.

Electrically it is correct, but the layout could indeed use work.

The trace from pin 1 on the SOIC should be re-routed so it doesn't go through pins 2 and 3.  That would be more DIY friendly by reducing the risk of solder bridges there.  The two vias on either side of BLK could be eliminated completely.  Vias are annoying for anyone doing a homebrew PCB.

Not to continue shooting a dead horse, but I would have taken an extra step and added a bypass capacitor for the flash chip.

not autorouter, I wouldn't touch the stuff, I'd agree with you about the routing, but I was on my lunch hour with a sandwich in one hand. I would be happy to share the design files with anyone that would like them. Likewise I would be happy to assemble them too.

I will try and sort out the layout today to make it easier. I suppose that i'm lucky that I have a board house that will make me free prototypes

Nope.  Progress postponed due to summer.  But summer is over and my time is freeing up to get back in to this stuff.  It is still somewhere on my list of things to do.

While you are at it, you could add an FTDI chip and a USB connector to the schematic and layout.  These could be stuffing options so the board could accommodate both a FTDI cable and a regular mini-USB interface.  An example schematic and layout from the GoodFet open source project is here (https://goodfet.svn.sourceforge.net/svnroot/goodfet/branches/goodfet41/) if you'd like to take a look.

I already have this done!!  :grin: I simply used the sparkfun design files and gave them a tweak. there's even room to put a legacy serial interface on the board.

I do prefee the FTDI cable option, since these are readily available and reduce risk for the DIYer.

That looks better! I always cringe when I look at a board and see unneeded vias.

I, briefly, thought about one sided. I don't think there's as much cost advantage these days as there used to be though. Unless you're going to make the board without silkscreen and solder mask.

I'd agree but if your etching yourself then single sided is easier, if your getting it made by a board house then vias make it easier to lay out. Out of interest do you lay out many of your own boards? I'm fairly new to this and trying to learn, but always appreciate constructive criticism.

I know this was directed at C2520, but I'm hoping to get setup to etch my own boards sometime this winter.  I am debating UV vs. toner transfer vs. direct resist application via inkjet printer.  Either way, single sided certainly makes life easier, both for the board itself and any kind of solder reflow scheme like toaster ovens or hot plates that might be used to actually assemble it.

Thinking of a home process, you could easily be less aggressive on your ground pour and increase the trace spacing a bit to make the design easier to DIY.  There is much more process error at home vs a commercial board house where shorts could creep in.

I used to layout boards at work, it's been a couple years since I've done one though.

I still prefer to minimize vias because they can be trouble spots, especially on a high speed trace. I've had to troubleshoot more than a few boards where the problem turned out to be a bad via.

I also like to make it look nice, by that I mean I would remove excess bends and turns. Like those off of pins 2 and 3 of the IC, the dogleg going to pin 3 of the 2mm connector, the two doglegs in the traces going to pins 4 and 5 of the other connector. Pull the traces from pins 5 and 8 of the IC a little closer to the mounting hole, so that there are only 2 45's, instead of 4 in that area. And maybe push up the traces along the top so they are a little straighter (would have to see how that looked though).

I seem to recall that one should avoid traces between the long sides SMT pads, like you have between 5 & 6, but I can't remember why...

Also, you won't need the center marks for the devices, those are only used for automated assembly.

Have you checked the datasheet/appnotes to see if a bypass cap is recommended? It's pretty rare that one isn't.

If you decide to make the board single sided, it's best to assume the silkscreen won't be used either. So some marks in the copper to insure proper part orientation would be helpful. As it is now, only the 2mm connector has some way to ID pin 1.

OK a bit of background, I work for a UK defence contractor producing a range of electronic equipment. The trace routes that I have used are purely for speed of laying out, the large copper pours are done at the recommendation of the board house (less copper to etch =  less time in etch bath = fewer mistakes)

For the DIYer I would certainly recommend getting your boards knocked up in china using a PCB pooling process, you can have you boards in less than a week, fully silkscreened. I have a "pet" PCB firm here in the UK for instance the cost per board for this design is around £3 (that includes resist layer, silkscreen and gold plating  8-) )

with regards to the "bypass" capacitor, I must admit that I had to familiarise myself with your term, but i agree it is probably necessary, but very simple to add to the design.

Once again, if there is significant interest I will get a stack of board produced (bare board, kit of parts or finished, it makes no difference to me) and distribute them.

I can't say I authored the term, I'm just a user of it.  I thought it was a rather common term.  

Once again, if there is significant interest I will get a stack of board produced (bare board, kit of parts or finished, it makes no difference to me) and distribute them.

Are you only making ones with the FTDI and Flash chip?  I'm more partial to having a level converter, but I'm picky. No offense.
Title: Re: Build Your Own Davis Console Datalogger
Post by: belfryboy on November 16, 2011, 04:57:40 AM
I believe "bypass" is more of an American term, we prefer "decoupling" as it more descriptive of what it does, (but some may argue the same about bypass)

http://en.wikipedia.org/wiki/Decoupling_capacitor

The layout can easily accommodate RS232 level shifting via the 6 pin header with some additional pins for power. I'll be at sea for a few day on a slow connection, but might update the design again during down time.

Out of interest, does anyone know how the console "knows" that a logger is attached? I seem to remember that my VP1 used to bleep 3 times with the davis logger on it, but only bleeps twice  with my clone, and weatherlink does not recognise the the console it attached at all. I suspect that there is a pull up somewhere that I haven't connected. Perhaps WXtech or C520 could point me in the right direction?

I've never gotten Weatherlink to work with my DIY USB->Serial interface based on the Sparkfun part.  I had been blaming it on Vista 64-bit software incompatibilities.  But maybe Weatherlink is somehow expecting the weird converter chip used in the Davis dongle and balks when it can't find it.  Not that I mind so much from a data collection perspective because Cumulus rocks, but I wouldn't mind playing with Davis' Streaming Data Utility.  It doesn't work either for probably the same reason.

Little help, anyone?

This board is the logging memory, the other chip on the Davis logger is a serial communications chip. I have this at the USB plug end, reducing component count on my board. This board can then be generic to serial or USB  :grin:

Everyone, if you are interested in a finished logger these are now available. If have tested it with Cumulus and WeatherDisplay with excellent results. This unit WILL NOT  work with davis weatherlink. I do not intend to pursue this route as it would only promote piracy of the WL software.

The cost will be $45 (or £30 in the uk) plus shipping. Logging interval can be set up using a terminal program like hyperterminal or Realterm, but I should have a setup utility finished by the end of the week.

Also if anyone has some webspace to store the design files for those that wish to make their own then please contact me.

Done and done.  I linked them from a new blog post (http://madscientistlabs.blogspot.com/2011/11/bad-news-and-good-news.html).  The design is cleaned up, more compact, and now single-sided to be more DIY-friendly.  I will add to the archive a little utility to activate the logging function once belfryboy and I sort out an email issue.

Let me know if anybody has an issue with downloading them.  I've mistakenly deleted them once already  ](*,)

I saw a post by belfryboy in another thread insisting quite forcefully that you guys had a davis-logger.  On the madscientistlabs blog, sure enough, complete with crickets.

I can't speak for anyone but myself, but I think the reason for the crickets was perception this may have been an extension of the "davis console pinout" thread, up to something like 300 pages now.  I've thought that thread needed to be pruned/spawned-off for some time and haven't been keeping up.  I missed out on THIS thread by thinking it was the same. 

Glad to see work continuing to move forward.  This thread is a must-see.

I have now received the boards from the PCB manufacturers, First three built and tested, another 17 ready for anyone that wants them. remember that these have the FTDI USB cable attached, and have the same logging ability as the Davis loggers. They will work with Cumulus and Weather Display, but not with Weatherlink.

cost is less than $70 (and that inculdes postage!)

PM me if you want one

Belfryboy, can you confirm a UK price for those who may be interested, please?

Also, (being a total luddite here) is there a way which your datalogger can work with Sloweather's interface? and be used to give the complete "all in one" type experience without paying the extortionate amount Davis want?? (and if not it's about time you two got together and made a bit of money with each other,LOL).

Post by: belfryboy on January 26, 2012, 02:50:39 PM
UKwoody,

this is the all in one package. It is designed to be used instead of the Davis logger and software. I would be happy to share the design files with Sloweather, to improve his simple interface (also it would be easier than me having to ship loggers to the states....).
Title: Re: Build Your Own Davis Console Datalogger
Post by: ukwoody on January 26, 2012, 02:58:57 PM
My appologies, for some strange reason I didnt realise it had the full interface as well, Doh!
So if I bought a Vantage Vue, I could use this and WD straight onto my PC (and thus the web)?

Appologies, I am extremely tired and somewhat slow at the moment!

Post by: belfryboy on February 04, 2012, 11:18:57 AM
 In creating this little beast a few people have found out that unless you are using weather link, you are unable to set the logging interval. this should no longer be a problem. If you use Cumulus the softare does not set the logging interval of the logger, so you have to use a terminal program to set the logger up. If you use Weather display, then just use the Davis datalogger set up facility included.

Thanks to a tame code monkey  (http://en.wikipedia.org/wiki/Code_monkey)I now have a setup program that works with my Datalogger clone. It connects via the virtual com port and sends the required commands, with only a little bit of help from the operator. Follow these simple steps.

1. Install the logger in the console as per the Davis instructions. (unplug the mains supply, remove batteries.)
2. Connect the USB logger clone cable to an available USB port and install the drivers from if here  (http://www.ftdichip.com/Drivers/VCP.htm)promted.
3. Figure out which port your logger is on by following these instructions. (http://www.avitresearch.co.uk/USBTTL/devicemanager.htm)
4. extract the LoggerSetup Zip file (attached to the end of this post) to a suitable location and open the WeatherStation Exe file. you should see a panel like this:
(http://farm8.staticflickr.com/7028/6817338049_b76949ac95_m.jpg) (http://www.flickr.com/photos/77614806@N00/6817338049/)
TEST (http://www.flickr.com/photos/77614806@N00/6817338049/) by belfryboy (http://www.flickr.com/people/77614806@N00/), on Flickr
5. Move the Com port indicator the port that you found your logger on, and hit the "open" button.
6. In the "Message" box type "TEST"  (IN CAPITALS) and hit send, you may need to do this a few times to wake the console up.  Once you get characters in the "received Messages" box you are ready to set the interval!
7. Using the drop down in the message window hit the "CLRLOG" message and hit send. this will clear any previous daa from the logger.
(http://farm8.staticflickr.com/7026/6817336971_e3eac10853_m.jpg) (http://www.flickr.com/photos/77614806@N00/6817336971/)

8. Now set the interval that you require, use the message drop down to select "SETPER" and the parameter drop down to select the value, then hit send. Remember to set this as the same value in Cumulus as well otherwise Cumulus can get upset and hang.
(http://farm8.staticflickr.com/7001/6817335025_08f68e6038_m.jpg) (http://www.flickr.com/photos/77614806@N00/6817335025/)

9. Then use the message drop down to select "START" and hit send.
(http://farm8.staticflickr.com/7170/6817336003_f8ef4f3a21_m.jpg) (http://www.flickr.com/photos/77614806@N00/6817336003/)

10. Close the Com port, and then the set up program and your logger is running! open Cumulus and away you go.

Hi belfryboy and all,

Received my DIY Logger today and after a little bit of fiddling and working out I've got it running perfectly in Cumulus through VirtualVP to boot! One thing to note is to remember to install the VCP drivers from http://www.ftdichip.com/Drivers/VCP.htm so that your weather software is able to connect.

(http://www.maxhawkins.co.uk/uploads/cumulus.png)

I am running this through a Windows Home Server unit, but I can also confirm belfryboy's Datalogger works fine on my Mac Pro on OSX 10.7.2 Lion, at least in WeatherSnoop. Again using the drivers off the website above. Obviously you need a PC to run the app to activate the logging if you want it to start saving data (should be possible in a virtual instance of Windows as well).

Extremely happy with this and will be doing some more testing and playing around with the device. Cheers again Rob!

Ta,

Max.

Looks like a nice little app, should make things pretty easy for anyone that doesn't know how to use a terminal program. A couple of things though...

6. In the "Message" box type "TEST"  (IN CAPITALS) and hit send, you may need to do this a few times to wake the console up.  Once you get characters in the "received Messages" box you are ready to set the interval!

You're supposed to send a LF or CR/LF to wake up the serial port, although I suppose just about anything would work.

7. Using the drop down in the message window hit the "CLRLOG" message and hit send. this will clear any previous daa from the logger.

This is redundant, the SETPER command clears the logger memory (that's done so that all data stored in the logger is of the same time interval).


Title: Re: Build Your Own Davis Console Datalogger
Post by: belfryboy on February 05, 2012, 05:55:19 AM
C5250,

I usually use the TEST message, just to make sure that it's all working, the LF and CR are sent in all the message anyway. (i sometimes like to use the "LAMPS 1" and "LAMPS 0" to prove I am the master of the console!

I wasn't aware that SETPER also clear the log, thanks!

Yep. That's right, it has the same storage capacity as the Davis logger. I can't be certain that it does the firmware upgrade, since I have a VP1 that does not support cable uploads, but if SloWeather's cable can do it, then I don't see any problems, perhaps anyone that receives one of my cables can give it a go and report back?

I have made sure that this will not work with WeatherLink software, even though I now know how to. This is to prevent software piracy, which has previously been a problem.

I would have thought that providing you havent gone out of your way to break their patents etc, and you keep things on a small local scale, it would probably cost them more to sue you then to let you get on with it. Especially since, (Davis take note here!) I only bought a Vue, BECAUSE you have made an interface available at a sensible cost. If I HAD to buy the Davis one, I would have bought the OS WMR200 instead due to lack of funds. So actually Davis have already gained form you.

Anyway, since they havent been onto Sloweather yet either, I really wouldnt worry at this stage my friend.
Looking forward to getting mine this coming week!

apparently Davis have a patent on either SPI communication protocol, or Dataflash chips, I didn't know that, thanks for pointing it out.
 :roll:
I have made sure that this will not work with WeatherLink software, even though I now know how to. This is to prevent software piracy, which has previously been a problem.

I'm sure Davis have been following this thread, and as of yet have received no contact.

I'm sure the datalogger is patented by Davis.  But unless you cloned theirs, yours is an new way of doing the same thing.  Unless the datastream from the connector on the back is copyright (like National Football League broadcasts, I don't think possible) then you are just using what you found, like DeKay with the wireless ISS data in his console project.  But if there is a patent on the protocol, then you can't create a new invention that creates it or uses it like an open standard.  If it was scrambled using a proprietary (trade-secret) method, then you would need their license to use it, like cable-tv signals.  If the chip is commerically available without restricted use, then that shouldn't be a problem, as when you patent a chip, you can control it's use through specific language in the patent.  For example, if it says "this chip is for logging the davis protocol" then they wouldn't be distributing it to the open market.  If the patent says "this chip can be used for logging" and they make it publicly available, you can purchase and use it for your own logger, just not clone/counterfeit the chip.  You can't patent a broad use, it has to be specific.

So, unless the answer to any of these questions is yes, you are probably in the clear, otherwise you will need a license from the patent holder to distribute/sell your derivative invention.  By the way, if you wanted patent protection for your NEW improved device, the clock is ticking.  Under US and EU laws, you have one year from the time you made it public to apply or it becomes public domain.


Note, this is not legal advice.  Consult an attorney for that.  I'm probably making all of this up.  YMMV.  Yada yada.

Davis usually list their patents in their documentation, and having looked through these I can see no reference to the datalogger. The datalogging chip is an off the shelf Dataflash chip, commercially available, and all Davis do is write values to memory addresses, and read them back again. I would suggest that it would be extremely hard for Davis to patent that process.

^^^ This ^^^.  And the entire data exchange is driven by the firmware on the console, which we neither copy nor modify.  The low level interface is Atmel's design, from their processor chip to their memory chip.  The clone logger is analagous to putting Energizer batteries into a Duracell flashlight.

What software piracy??  You can freely download WL if that is your concern.  Sure, they say you need a license, but that sure does not match with their actions.  heck, I think the CD license is really just the cost of the box and CD.

Post by: belfryboy on February 13, 2012, 03:52:52 PM
AFAIK you cannot download WL in it's entirity, just the upgrades. Either way using it without a licence would be deemed as piracy, certainly in the UK it would. Whilst many people do use "hooky" copies of software, I do not wish to promote this. Likewise I would not suggest that any one uses a hacked copy of WeatherDisplay.

BTW I am a licensed user, but when my Davis logger got zapped it needed to find a cheap way of archiving my data, and this thread provided it. I really love Davis kit, even if I have spent a fair bit of time servicing and repairing it.

I switched back to 5.9.2a-beta, because with 5.9.3 I experienced big gaps in my CWOP uploads when it would attempt certain APRS servers.  In 5.9.2 this would crash WL.  In 5.9.2a-beta it would keep trying and eventually hit a working server.  In 5.9.3 if it times out, it would skip it, leaving gaps.  That's not Davis' fault (the slow reponse from certain APRS servers) but the 5.9.2a-beta seems to be the best solution for me.

I misplaced my CD shortly after my first installation.  Every move and re-install has been downloaded from the link mentioned above (5.9.3 and 5.9.2a-beta)

It's good to be concerned about software piracy.  However...

A question:

I have a Davis serial logger, which includes a "license" for WeatherLink.  I have a copy of the WeatherLink Version 5.5 Installation CD, and I also purchased an Extra User License (Davis Part #: 06510X).  I have two consoles, and I'm considering getting one of these Dataloggers (probably with your wireless addition) so that I can connect to the second console and experiment with software on an additional PC.

It's my responsibility to be properly licensed.  So, why shouldn't the Datalogger (as delivered) work properly with WeatherLink?
Title: Re: Build Your Own Davis Console Datalogger
Post by: ukwoody on February 15, 2012, 03:27:53 AM
Dalecoy, you're right that it is your responsibility, however, if I were belfryboy, I would not want to do anything to "encourage" you to break the rules. Furthermore, I personally would also disable the unit from working with WL to avoid any possible future threats from Davis.  Theres no point in deliberatly upsetting them is there?  Sometimes it's better to let sleeping dogs lie...

Dalecoy,

I was working for McMurdo during the upset caused by Bluewave with their datalogger. One of the problems was piracy of Davis software.

Regardless I am not willing to make this work with Weatherlink, the hassles are potentially too much. I have done this for Vantage Pro/Vue users that previously wanted to get their data archived, but had no means to do this other than the Weatherlink route.

Besides if you have bought weatherlink than you have a datalogger, whats the problem? If you have multiple PC's then get another davis license, it's cheaper than my logger.

Who in their right mind would want to pirate Weatherlink  SW?  Heck, even Davis doesn't protect the code.  And at the end of the day, Davis cannot stop an INDIVIDUAL from producing  a device that works with WL.

OK, I respect your thoughtful decision.

Besides if you have bought weatherlink than you have a datalogger, whats the problem? If you have multiple PC's then get another davis license, it's cheaper than my logger.

Please re-read what I posted.  I already have another Davis (Extra User) license from a previous purchase.  And I have two consoles.

The point was that to use that second console for data capture, I need another logger.  And your hardware (with the wireless addition) seemed to offer an attractive way to do that conveniently.

However, it's clearly your call.

I was just hunting a quick example.  I don't know (or want to know) how easy it would be to hack that code, etc  The point I was trying to make was the responsibility of hardware vendors.

Do we expect HP or Dell to be responsible for making sure their computers can't run pirated or unlicensed software?

Of course, if HP or Dell encouraged the use of pirated software, that would be another matter.  But I don't personally consider "ability to be used with WeatherLink" to be encouraging someone to do that.  [Regardless of whether Davis makes unprotected WeatherLink software freely available]

I don't have any problem with belfryboy doing whatever is his preference, of course.  I'm just saying that it's fundamentally the responsibility of the user to make sure the licensing is legitimate.

Curiously, I found and nothing about the workings of the datalogger whilst working for them and have only recently discovered, through this forum, the inner workings of Davis kit. So I honestly have little insider or proprierty knowledge of their equipment.

As a service technician I found it almost impossible to understand the guts of their kit because the "training" revolved around;

"this is how to fix a faulty ISS, first take your screwdriver, removed faulty ISS, replace with working ISS, dispose of faulty ISS....."

I come from a background of component level fault finding, so once you get a feel for the circuit boards the rest just comes naturally.

That's not too surprising though Rob, is it? The VP logger is obviously potted and so there's essentially zero that you can do with it in the way of repair. Though Kevin clearly did work it out - maybe it's not too different from the 7862 logger, which was more open IIRC.

Don't the economics of any repairs also come into it? I guess that on average the total cost of repairing a board in engineer's time has to be eg $80-100 (unless it's an obvious fault like a supercap or a battery connector with a loose wire), by the time you factor in troubleshooting, diagnosis, repair and testing. So for something like a VP2 system it's just not going to cost-effective to do other than just to replace the board in general. I agree that it's shame that there's not more scope for repairs but I can see the economics involved.
Title: Re: Build Your Own Davis Console Datalogger
Post by: belfryboy on February 15, 2012, 06:43:23 PM
Sorry John, but I have to disagree with you to a degree. It is often very cost effective for a skilled technican to diagnose and repair a common fault in a relativly short period, before resorting to replacement. Remember we were supporting VP 1s at their end of life, with no supply of replacement boards, and any request for information was met with a resounding "no". The ill will that was felt towards Davis when customers were told that the best thing they could do was shell out for a VP2 was a little hard to swallow.

Reliability has improved, and the VP2 is well supported, so I would hope we are safe for now.

But I feel this is getting of topic.
Title: Re: Build Your Own Davis Console Datalogger
Post by: johnd on February 16, 2012, 04:17:36 AM
Just to be clear (and at the risk of continuing the OT drift I know, but it's not an uninteresting point) automatic whole-board replacement is not a trend that I welcome. But if the marginal manufacturing  cost of a board were say $25 (which is a total guess for an ISS board, but I suspect not wildly out) then it's fairly plain that - purely on business economic grounds - you can't allow an engineer to spend too long trying to fix a fault before it becomes more cost-effective just to replace it as a matter of course.

Coupled to an Arduino, you have transmit and receive capability for not a lot of cost.
It can do fixed frequency, frequency hopping (Spread Spectrum) and send data in various modes with adjustable power levels.

Arduino library for the RFM22 (433MHz)
http://www.open.com.au/mikem/arduino/RF22/

Maybe use the Arduino to store data as well? (SD card shield).

I don't write software as I'm more a hardware kind of guy, but there is quite a bit of open source code around if you google it out.

I am just knocking up the next 10. I have not tried it with weathersnoop, but see no reason why it shouldn't. Just remember that although it uses an FTDI USB interface, this is a virtual serial port, I see in this link (http://www.tee-boy.com/forums/viewtopic.php?f=4&t=241&p=892&hilit=davis+ftdi#p892) that it is supported though. I of course supply you with drivers for the interface.

The same goes for Meteohub and weatherhub

Do you have any of the wireless data loggers I've seen posted on the Sandy Forum for sale yet??

Any thoughts about building an IP logger.  I really want to pull the trigger on one of these but I don't want it near a computer.

Although I was considering the Acu-rite station, the belfryboy logger has caused me to order the Davis VV.

And in anticipation of the arrival of both I've been trying to read up on the how-to-make-it-works.  After reading the Davis documentation and many of these threads, here's what I've come up with:

 1. Enter console SETUP mode to save current data and to stop writing data
 2. Power down console  (take out batteries and unplug ac adaptor)
 3. Plug logger into console
 4. Plug USB into desktop computer
 5. Power up console (plug in ac adapter and then insert batteries)
     console will beep (4x for VUE?)
 6. Check console baud rate (19200 default/fastest)
 7. Run LoggerSetup (WeatherStation.exe) software?
 8. Run weather software and configure it

Does the WeatherStation.exe file also install the necessary driver(s)?

Have I missed anything?

I got my belfryboy logger on the 16th.  It looks like it took nine days to arrive.  It works great!

I'm going to try to use it with this: http://www.amazon.com/over-Cat5-Extension-Cable-Adapter/dp/B003BDMK3S/ref=sr_1_1?ie=UTF8&qid=1342816269&sr=8-1&keywords=usb+cat5 (http://www.amazon.com/over-Cat5-Extension-Cable-Adapter/dp/B003BDMK3S/ref=sr_1_1?ie=UTF8&qid=1342816269&sr=8-1&keywords=usb+cat5)

It will be at least a 60ft run from where I want the console to the computer.  I'll report back on how it works.

that looks about right, but full setup instructions are also included with the logger. The setup software does not install the usb drivers, this is done separately, they are available from the ftdi website. It should be noted that the console will appear as a virtual serial port, and not USB device. i.e. Set any software to serial not USB.

It is working fine with a 6ft ethernet cable.  I'll find out tomorrow if it works at much larger distances.

The converter says it will work up to 150ft so I expect no issues.

It has been running since yesterday using a long ethernet cable from the console down the hall to my office.  No issues.

I'll be running the line in the crawl space sometime this week.

I shall be ordering a new batch of boards very soon, but with a twist. I have modified my design and added 2 LEDs so that the USB chip shows TX/RX traffic when in use.  Thanks to all those that have purchased the logger. I would love any feedback/suggestions.

just a quick point to note, it seems that shipping to the US takes between 10 and 14 days, I guess that's due to customs checks.

My apologies to all those that have ordered in the last few weeks for the slow delivery, I have been working away from home and just got back to a whole load of orders. I have sent as many finished units out as I can, and just finished potting the next, so your orders will be out in the next day or so.

As of today I only have 5 boards left, so I will order the parts to finish them off and hope to make them in the next week, as long as i do not end up going off site.

Are you trying to emulate the flash chip?  If so, "The data in the status register is constantly updated, so each repeating sequence will output new data."  Ref: 45DB011 Datasheet (http://www.atmel.com/dyn/resources/prod_documents/doc3639.pdf), Section 11.4.  Look at Table 11-1.  Not sure of the page size though.

FEEDBACK!

Hi all, just thought it was about time I posted a little note (and a thankyou) to Belfryboy for his logger/interface.

I ordered one at the end of January this year, so I had one of the early ones.  It has been running almost nonstop for 8 months now.  There was a Small two week hiatus when my pc died, but otherwise it has been on 24/7 ever since, connected to my Vue.

I run WeatherDisplay and WDLive and there hasn't been a single hiccup in that time.

So, for the money this is a superb bit of kit, that has been very reliable and I am well chuffed with the performance. 
just wish I could afford to buy the wielss one,lol.

So if any of you are a bit unsure, speaking personally based on my own experience, I wouldn't hesitate to recommend them.

Just for clarity - Belfryboy had no idea I was posting this and I haven't been in contact with him since purchasing it, so it's totally unsolicited :grin:

Hope this is of interest (especially with Crimbo just around the corner).

Kind regards
Woody

Before you go too far down this road, verify that your console firmware rev is less than 3.0, and/or your console manufacturing code (on the lable on the back) begins with a sing;e letter followed by numbers, not 2 letters. None of the aftermarket serial interfaces currently work with the 3.x firmware/2 letter man codes.

You'd need to be certain that it worked at 3.3v and not 5v, otherwise you will junk your console. I do have 5 boards left at the moment, but I am currently working away from home and will not be able to ship until later next week.

The blue tooth is interesting but the soldering looks way too tricky for me.

My Vue arrived today and it meets the criteria for the serial mod :-)

Found a cheap 20-pin connector on ebay:

you need a 2X10 way connector, and make sure it is 2mm pitch, they usually ship a 2.54mm pitch header.

This is the mating half to the one on the console, cost is £1.76

I have the same question here, as I am considering buying me a Pro 2. Is there any IP logger clone available ?

Thanks !

I bought one of the early SLOweather data logger non-Davis cables for my Vantage Vue but have never been able to get it to work with Linux.

Is anyone using Linux with one of these newer alternative data loggers and a Vantage Vue?

Is anyone using the newer alternative datalogger with a BeagleBoneBlack or Raspi?

Has anyone tried it with weewx?

Thanks!

Does the Clone Logger Setup application posted several pages back still work?

I followed the instructions and pointed it to the com port where my data logger is, and can get it to connect, but when I type TEST and hit send, I do not get any messages back. I have hit the send button several times as well. I do notice on the logger that when I hit the send button, a green LED will flash, so I know its at least getting the message. Anyways, was trying to adjust the archive interval of the device from 30 mins down to 5 mins. Approximately how many entries, or how long can I store data on that logger with a 5 min interval? This is just for power outages.
Title: Re: Build Your Own Davis Console Datalogger
Post by: JHellis on July 03, 2014, 08:24:09 AM
Hi

with the interval set at -
1 minute    = 1.7 days
5 minutes   = 8.8 days
10 minutes = 17.7 days
15 minutes = 26.4 days
20 minutes = 35.4 days

Hope this helps.

John

Awesome, that helps me on that front then. Has anyone tried using that software to update the archive interval of the logger? Still can't seem to get mine to send back messages.
Title: Re: Build Your Own Davis Console Datalogger
Post by: JHellis on July 06, 2014, 05:01:24 AM
OK

I am not sure what software you are using for the Data Logger; I am assuming that you have one of the later models that emulate the original Davis dataloggers. If this is the case then I cannot help you as I have a very early Belfryboy Datalogger that has to be run by custom software.

I have attached the software that I use, see if that works for you.

I'm looking at installing a Davis Vantage 6152 and want to send my data to WU without having to run the pc 24/7.  Would the following work:    Connect a belfryboy's datalogger to the Davis console and TP-Link TL-MR3020 running meteobridge.  The meteobridge connects wirelessly to the wireless router, sending the data on to WU?

Thanks for feedback.  Keith

Sent for one of BelfryBoy's data logger clones on Monday, 12-NOV-15 and it arrived on 19-NOV-15.  Plugged it into my Vantage Pro2 console and into a USB port on my computer.  Windows assigned it the designation of COM4.  Ran WeatherLink software and selected COM4, then opened Virtual Weather Station and selected COM4.  My weather station is back online again and I'm happy.
Thank you Bob for making a fine quality, reasonably priced product available.  =D&gt;

Has anyone got this working with Cumulus MX?  I am not getting any data from it.  I previously had Cumulus MX working with a FineOffsets weather station.  I am running Cumulus MX on a Raspberry Pi under mono.

Have you tried the logger on a pc to see if there us a problem?

Did you power down the console before fitting the logger, and how many beeps did you get when power was reapplied?

I have not tried on a PC yet as I currently only have a Mac.

I did power down the console after putting it in setup mode (per the instruction sheet).

It seems like I am not getting the right number of beeps.  I get 1-1-2.   That is 1 beep and a several second pause, another beep and pause, and then 2 beeps.
Title: Re: Build Your Own Davis Console Datalogger

Are you running a Vue?if you are then 4 beeps would be right.

Yes I have the Vue. The beeps weren't that close to each other so I thought that might be an issue.

The logger will also work with Mac, but I don't own one so I'm not well placed for Mac support. But if the mac recognizes the logger then the two main parts are working.

I have not used Cumulus on a Pi, but if is anything like on the pc then the logger appears as a serial port, not a usb device.

I installed a couple Mac weather programs and got it to work with one of them.  The other didn't for some reason.  I will dig into the Cumulus MX issue a little further and see what I can come up with.

I realize this thread is a bit old, but are the blank PCBs for this thing still available? The link to OSH Park is dead but if I could get the gerbers I can have some boards made, or a schematic to do my own layout.

Unfortunately the dataflash chip is obsolete, although they still can be found for now. Does anyone know what Davis is using in the current production loggers? Have they gone to a new part or do they have a hoard of the original chips? The firmware in my Vantage Pro2 console is 3.6something, does it still authenticate the flash chip? It's really irritating that they do that, I don't mind paying the premium prices for the equipment because it's quality stuff made here in the USA but I hate being gouged for a feature that comes standard practically every $100 Chinese weather station on the market these days. The Davis approach to exporting the weather data is very 1995.

Post by: james_s on February 04, 2017, 12:36:53 AM
Which part stopped working, the logging or the serial port? There are only two semiconductors on the thing, not a whole lot to go wrong. Flash memory does wear out eventually so that may have happened, especially if the console is writing to it frequently.

In what way did it die?

Could your PC still "see" the com port? Or did the console stop recognising the logger?

The computer (Raspberry Pi) stopped seeing the USB port or got errors while trying to connect to it.  I tried the logger in 2 different consoles with the same issue. Multiple USB ports were also tried.  It worked perfectly for about 10 months before slowly getting worse and worse.  My new Davis brand logger is working fine I know the issue isn't on the Pi side.

Potentially yes, it would involve removal of the epoxy resin, and then replacing the cable mount. It's not the easiest thing to do, unless you are trained in advanced PCB repair.

I think removing the resin will be the hard part. Any tips on how to do that?

I usually use heat to break down the epoxy, either a hot air rework tool or a chisel tipped soldering iron. This is done in a fume cabinet as the fumes generated are toxic. It also renders the soldering tip unusable. The epoxy is broken down in small swathes, and then carefully scrapped back, and repeated until the desired area is cleared. The solder pads are then carefully cleaned with isopropyl alcohol and inspected for solderability.

At work I would expect to take about 2 hours to do this properly.

Hi Belfryboy,
I have ordered one of your Davis Clone USB loggers from you and have a couple of questions about linking it to my clone Meteobridge TPLink N150 router with the 3G/4G 2.0 USB input. I have installed Meteobridge firmware on the router to make it a WiFi access point and would like to know what port number to use, along with the TPLink N150 access point IP, with your Davis Clone when configuring the TPlink N150 access point with the Meteobridge configuration program?
