It is possible that your combo unit uses the same pinout on the RJ12 connector.
You can check it easily:
With the TX board unpowered connect the RJ12 connector from the unit to the RJ12 connector on the board:
- While rotation the anemometer, check continuity between pin 3 and pin 4. Contact should close twice on each rotation. If it does, anemometer is working.
- While slowly rotating the wind vane, check resistance values between pin 3 and pin 5, if they change for each cardinal point, wind vane is working. If your wind vane uses resistors with the same values than the stand alone unit, then you can use it. Later, when you finish the board you can test this by looking to the readings from the wind vane. TX software includes some debug options, which will help.
