Hello, I have a Davis Weather Uploader, or thats how it uploads from my Davis Vantage pro 2 to my USB to my computer to the internet. And the Com Port that i used in in WeatherLink was comport 3 wich i used in weatherDisplay, And WeatherLink is also Set to serial, Im not shure or what have you were i need to get the serial. I do believe i did find it several times but put it in but still no dice. If any one can throw me up some pics of Weather display on how to put in the serial number and or com port and to get this working it would be much apreshiated. Thanks so much. Steve
