[aprssig] Davis Vantage Vue and RF APRS

Yes, I agree and that's why I own Peet stations.  The guy I'm trying to help already has the Davis online feeding CWOP and he is feeding APRS-IS.  That's how I found him.  I approached him about getting it on the RF side and he's onboard.  I just have to come up with a solution to help him do that.

Guess if you already have a Davis it might not help, however if someone is still looking for hardware that could be a huge selling point.

There was some kind of authentication or handshaking that required adding an EEPROM to the adapter and getting the correct contents loaded into the EEPROM. 
  
  I initially attempted a similar project, but ended up giving up and using a WeatherLink Live to get the data to the internet, then pulling the data down to my APRS node to send over RF.

   Well, maybe I should have researched JUST a little more.  I found out that the adapter plugs into a multi-pin expansion port on the Davis display console.  I found a pinout for the port and there is TTL level serial, along with ground and +VCC to power the adapter.  Looks like an easy ST3232 TTL-Serial adapter mod job using a PCB.  I'm curious to see what format the serial data is coming from the port.

       Does anyone on the list have any experience with getting a Davis Vantage Vue weather station on RF APRS?  I am trying to help another guy get this going.  From what I have found out so far, it looks like Davis makes an (RS232 Datalogger) that looks like some kind of TTL to RS232 adapter going from an RJ45 to a terminal block that I guess is putting out RS232 levels and still needs a cut off serial cable or something similar to complete the wiring job.  The major problem with this is, the adapter is another $225.
  
  Has anyone found a better (lower cost) option.  I see that WeeWX running on a Pi has native USB support for the Davis and even feeds to the CWOP servers, but I can't find any support for APRS whether through a direct TCP/IP feed to APRS-IS and/or a way to reformat the data to a Peet Bros or other similar format and then spit it back out at serial (TTL or RS232) levels that I can then feed to an OpenTracker or similar APRS device to get the data to the actual RF network.
  
  Any guidance would be great!
