How to Talk to a WeatherDuck
Commands to the WxDux & responses
The WxDux sits on the serial port it listens
for and responds to ASCII text sent to it and
returns text. This can be seen by starting
Microsoft's Windows application HyperTerminal.
Use 9600 baud, no parity and no flow control.
Use of flow control will completely halt any
communication with the WxDux.
Send (case sensitive). Do not send the quote
marks, just the letter.
- "T" gets temperature in C and F in the
format CC.CC(FF.FFF)
- "H" gets Humidity in %
- "L" gets Light Level (zero is dark, 100
bright)
- "F" gets Air Flow. Still air is
about 10, rushing air is about 200.
- "0", "2", "4" get the condition of the
three contact closure sensing, zero is
closed, 99 is open.
- "@" gets the internal unique serial
number.
- "X" cycles through and changes the baud
rate.
- "B" begins automatic transmission of the
entire data string every three minutes.
- ":" turns the internal LEDs off.
- "<" turns the LED #1 on
- ">" turns the LED #2 on
- "V" set verbose move on
- "v" sets verbose mode off.
Note sending a "B" gets a
complete string of data such as "67.8, 23.4,
43, 34, 99,99,99" which translates to:
Temperature = 67.8F (23.4C)
Humidity = 43
Light level = 34
Contact sense 1 = 99
Contact sense 2 = 99
Contact sense 3 = 99
