DS2482 is I2C - 1-wire bus, so boneIO can read temperature from DS18B20 sensors.
You need to know I2C address of device you want to connect to!
Most common address is set up to 0x18.
For first setup turn on debug logging for app or at least for module
DS2482 will scan for all available devices connected to it. You will see logs like:
