Erster Gehversuch mit Visual C#, ELV ASH2200 und ELV FS20 WUE

1. ELV FS20 WUE und ELV Mini-USB-Modul UM2102 zusammenlöten
2. USB Treiber installieren
3. Mit RealTerm 02002fb01 (Textmode) aktivieren und schauen Statusabfrage 0201f0 durchführen
4. Sensoren  in Betrieb nehmen 
5. SimpleSerial Beispiel von http://csharp.simpleserial.com/ (Visual C#2010 Express) installieren
6. Beispiel mit FS20 WUE spezifischen Elemente erweitern (initialisiertung, status, reset) - siehe code snippets weiter unten
7. Start SimpleSerial, click auf "start" und dann "status":
   Status: OKBaudrate: 4800 bpsFS20-Pakete: 0Wetterdaten-Pakete: 0
8. Etwas warten, dann trudeln auch schon die Wetterdaten der 3 Sensoren ein
   Sensor: 1Adresse: 1Temperatur: 1,9 C (0x0013)Luftfeuchtigkeit: 86,2 % (0x035E)Windgeschw.: 0,0 km/h (0x0000)Niederschlag: 0 (0x0000)Regen: Nein (0x00)
   Sensor: 1Adresse: 0Temperatur: 12,1 C (0x0079)Luftfeuchtigkeit: 72,5 % (0x02D5)Windgeschw.: 0,0 km/h (0x0000)Niederschlag: 0 (0x0000)Regen: Nein (0x00)
   Sensor: 1Adresse: 3Temperatur: 12,2 C (0x007A)Luftfeuchtigkeit: 67,1 % (0x029F)Windgeschw.: 0,0 km/h (0x0000)Niederschlag: 0 (0x0000)Regen: Nein (0x00)
