Thank you.
I attempted to upgrade to v3.12 but receiving no serial or USB device is found message.
I am using a Prolific Serial to USB converter with SloWeather's original DataLogger.
Am I unable to update due to this reason?
Or am I doing something incorrect?
Don't update. As I understand it, Davis changed the firmware to render 3rd party loggers/cables incompatible. I bricked my VP2 console while attempting to update with SloWeather's logger and had to ship it back to Davis, and it came back with 3.12. I had to buy a Davis datalogger so I can continue to keep records and share my data to various sources. My repaired console arrived last week, and the logger arrived today. All is connected, though the console is now down in my server room. I have a 50' connection down to the server room from the home office. I'll have to get a cable crimper to attach an RJ-11 connector to Sloweather's cable. I really hate to cut his connection off that cable, but if I want the console up in my office...
Davis really pulled a nasty one with this "update".
I'm working fine with SloWeather logger. Upgraded to 3.12 and haven't had any problems. I did modify my cable to work with Weatherlink so I'm not sure if that is what made it work.
What modifications did you make? Please let us know as I'd like to move my console back up into my office and use the 50-foot cable attached toSloWeather's logger.
I took a standard DB9 cable and cut one end off. If you collect computer parts and cables I'm sure you have one of these laying around. Cut one of the ends off to expose the wires. Depending on the quality of the cable it may be color coded. If it is color coded here is a guide that tells you which pin goes to which wire. You might want to strip back one of these and use a meter to make sure this guide matches your cable.
If the cable isn't color coded you are going to have to use a meter to figure out which wire goes to which pin. These cables are super cheap and if you find yours doesn't have the color wires and you don't want to mess around then go to goodwill or salvation army and they usually have a bunch of these cables laying around. You should only pay around a $1 for a new cable.
Now that you know which one goes to which pin we can use the pinout of a db9 to figure out what cables we have to connect.
If you look at your data logger from Sloweather you can scrape a little of the black off just beneath the three pin connector and you will see that he has labeled them. Use the two guides above to connect the TX, RX, and ground. The pinout guide above calls TX ->TD and RX -> RD. To get these to connect you have a couple options. You can solder them or you can find an old computer fan connector. If you locate an old computer fan you will notice a 3 pin female connector on one end. If you cut it off and strip the wires you can use this as a connector. Now just connect the stripped wires from the db9 cable to the stripped wires on the 3 pin connector. Use some electrical tape to hold them together. This doesn't look very good so you may want to eventually solder them together.
Basically, you have just built the same cable that came with your data logger. The cable should work and I recommend testing it before going forward. If it doesn't work, try flipping the TX & RX connections and see if that makes a difference. Now we need to make this work with Weatherlink and Firmware updates. A big thanks to DeKay's blog post that explains what we have to do.
http://madscientistlabs.blogspot.ca/2012/02/make-your-diy-davis-datalogger-work.htmlFirst you need to strip back wires CTS(7) & RTS 8. Once you have them stripped you can just connect them together. Solder or put tape on them.
Next, strip back DTR(4), DSR(6), and DCD(1). Just like above, connect them all together and solder them or put tape on them.
That's it, your cable should work with weatherlink and firmware updates.
