RS485 Wind Direction Transmitter

[pylon]

@zeldhris

  node.begin(2, Serial);   // wind sensor id = 

This says that the hardware serial interface should be used for Modbus.

@zeldhris

  if (resultMain == node.ku8MBSuccess) 
  {
    Serial.print("Result: ");
    Serial.println(node.getResponseBuffer(0x10));
  }  

This writes debugging output to an interface that was previously reserved for Modbus.

Do you see the problem?
