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.
Once upon a time there was a company called BlueWave who made a clone logger, that had double the standard memory ;)
can you buy a console separately, cos you'd need one to work with your logger, right?Did that a few weeks ago, converted my wireless ISS to cabled (more reliable, and I can 8-) ) now just doing the logger thing, Thanks DeKay

It won't.
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.
<snip>
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)
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.

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.(http://1.bp.blogspot.com/-B-ByS5H21tY/TsGuHdXafUI/AAAAAAAAAR4/phP4GNdNb_E/s1600/Archive+-+47+hours.JPG)

Any more results on the IM-ME device? Would be neat to strap a radio interface to an Arduino or similar and have a home-brew console.
here is the updated layout, I may even change the 6 pin header to SMD so that all the baord can be made single sided.
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.

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.

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.
It reads the PROM status register.there is a solder bridge between pins 5 and 6. The logger is working succesfully with Cumulus, but not weatherlink.
Looking back at your pics, I don't see a connection to the VCC pin...

As long as you weren't trying to use that USBExpress (or whatever they call it), I doubt WL cares what the chip is.
I would suspect a flow control issue.
I thought there were 2 chips on the datalogger and not just one. Is your board just an interface with no memory ? Or does it hold records ?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:
Here are some snaps of the latest issue board
Also if anyone has some webspace to store the design files for those that wish to make their own then please contact me.
Here is the logger setup utility,
download and use it as you wish.
Crickets??
My latest post (http://madscientistlabs.blogspot.com/2011/12/please-read-this.html) reveals the connection between Britney Spears and the great physicists of our time, but is totally unrelated to weather stuff.
And in honour of our great Chip-meister,I dropped a C-note to the Sally Ann today. I figure anyone who can ask for cash from drunks in a bar deserves some help.
Can't wait for mine to arrive, the WeatherLink is so overpriced which is a shame considering Davis' stations are so good!
BTW Max, this is your one on soak test in my VP1 console! On it's way to you today!

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.
belfryboy,The cable length is 1.8m and has a USB termination.
what length of cable is attched to your unit please, also what does it terminate in? is it a USb plug or serial??
many thanks

Maybe I missed this, but does this item also store data like the Davis version for a period of time in case WD gets hung or is shut down?yes, that is posted in the information in this thread
Maybe I missed this, but does this item also store data like the Davis version for a period of time in case WD gets hung or is shut down?
I currently run sloweather's cable which works fine... Also is this cable capable of doing software updates to the console should Davis release one in the future?
Ref belfry boy
Is there a way to configure your datalogger to work wirelessly from a Vantage Vue to a PC?
I will not be able to run a cable from here my console is situated to my PC, so I'm looking for a workaround to allow me to save the data to my PC.
Any help / guidance much appreciated
Hi Rob Received and installed the logger
All is working beautifully thanks very much!
The only thing that caught me is in the configuration screen of Cumulus
Make sure communication is set to serial not USB, I thought as it had a USB connection that was the one to choose,
After a few minutes of playing around, clicked on serial and hey presto!
I have data!

Thanks Chris, i hadn't thought to point this out, but that is correct. since the PC sees the logger on a virtual com port, then Cumulus should be set for serial.

Nessimmersion
Belfryboy logger is priced at £50 (and that includes postage.) although I could add acouple of wireless transponders for about £30, give me a couple of days and I'll let you know if I have a solution...

So the question is when will the lawyers be calling regarding patent violation. Or perhaps you have a arrangement with Davis to market their patented technology?
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.
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.=D> Brilliant example of free-market capitalism.
I'm sure the datalogger is patented by Davis.

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.

Sure you can! Right off the Davis website.. In fact they promoted it when all the 5.9.3 issues arose.

Dalecoy,
...
Regardless I am not willing to make this work with Weatherlink, the hassles are potentially too much....
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.
Including (for instance) Weather Display if I'm violating the license terms?huh?
was working for McMurdo during the upset caused by Bluewave with their datalogger.I did wonder if you might have worked for them ;)
QuoteIncluding (for instance) Weather Display if I'm violating the license terms?huh?
If users want to install WD on another pc they just need to email me for a new code, simple as that
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]As I said, Davis see it very differently!
I did wonder if you might have worked for them ;)
Curiously, I found and nothing about the workings of the datalogger whilst working for them
If the logger had a WLan interface added or the board had a layout that one could be soldered in I would buy it immedeately. I am currently using http://www.rovingnetworks.com/products/RN_174 and it works like a charm.The serial logger would do this, it has an RS232 output.
Have you thought of these for wireless transponders?

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??Yes I do. I make these to order, and have already delivered a few. I'll PM you details, or follow this link. (http://www.wxforum.net/index.php?topic=15739.0)
one left for immediate despatch. 5 more on their way.

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.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.
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?
Thanks,

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.

Correct!
Please do let us know how/if it works.
I finished the crawlspace cat5 run yesterday and everything is working just fine with the USB-cat5-USB converter. I would say this is a reliable and feasible solution to any who need to have their console and computer separated.
@ belfryboyI can sell the bare PCB, and I would of course send a parts list and short assembly instructions, PM me for details.
Do you/would you sell a barebones PCB?
Nigel (in the UK).
Okay -- Is there a driver for this to work on a Mac? If so I'm on the train.There certainly is, it uses the ftdi chipset which does support max use. To order just hit the PayPal button at the bottom of my post, and leave a "note to seller" that you require a mac version.
Thanks
On initial power up, at some point in the sequence, on the expansion connector the following happens:
Slave Select goes low.
An attempt is made to read from address 0xD7.
Address 0xD7 is the Status Byte for the 45DBXXXX. Can someone with a data logger tell me what the returned Status is?
Are you trying to emulate the flash chip?
Not sure of the page size though.
So, for the money this is a superb bit of kit, that has been very reliable and I am well chuffed with the performance.

Hello Belfryboy,
Do you have anymore dataloggers available?
Thanks,

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?
Are you running a Vue?if you are then 4 beeps would be right.
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.
Mine died recently after 1 year. I don't suppose there is any warranty. I had to buy a real one. :sad:In what way did it die?

Could your PC still "see" the com port? Or did the console stop recognising the logger?
That sounds like the cable came away from the board. I have changed the design now to give more support to the cable.
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.That sounds like the cable came away from the board. I have changed the design now to give more support to the cable.
