I have a catalog from Davis for 1999 and it list the wireless station. Model #7440w with rain gauge outside temperature, humidity, anemometer and inside barometer, temp, humidity. List for $795. The unit with solar power, model 7440S list for $895. To hook up to a computer you needed the data-logger with the weather-link software package, list for $165. The range of the unit was “100' to 400' ”.
In 2000 Davis introduced the Vantage Pro wireless version with solar pane,l 6160, listed for $595. Go figure the pricing! Oh in the 2001 Davis catalog the wireless 7440w is no longer listed, still could get the cabled version.
From what you say about the data-logger hanging out the back it sounds like you are missing the desk stand/wall mount bracket. The data-logger fits inside and the console fits on top. I hope this information will help, good luck with the unit.
