New wind sensor - Pypilot + Davis

[Erickalon]

Hi Sean,
I have made some more check on board this afternoon. I have tried to wiggle the connector with no effect. I have measured the voltage on the PCB.
Between Gnd and 5v: 4.97 v
Between Gnd and Speed, 4.7 v with a very low observed wind speed, display 0.0.
Between Gnd and Dir, 4.0 to 4.1 v, observed direction 10 to 20° port, display 65 to 70° (offset is 0 and anemometer is oriented backward).
At home, I have connected the weather sensor on my PC with Putty, without anemometer, and I get the following reading:
Sensor type:davis
Wind Off:0
Baro Off:0
Temp Off:0

I can make the same measure on board later with the anemometer connected.
Have you an idea on this issue? did there is a mean to check the integrity of the software?
Many thanks,
Eric
