<p>From what I remember that was one of the selling points of a Peet
Brothers Weather station over Davis. They claim it at #5 ( APRS
Ready) of their Ten Best Reasons to own a Peet Brothers.</p>
<p>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.<br>

<div>I had a friend who made an adapter to connect in the back of
the display console. 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. <br>

<div>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.<br>

<div dir="ltr">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.<br>

<div dir="ltr">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.<br>
</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">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.<br>
