I2C Address Setting #
In the basic units of NORVI Analog Input Expansion, the Address of the unit is fixed to 0x48 at the factory.
On modules with Address configuration options, I2C Address of the expansion module can be configured by switching DIP Switches in the bottom of the expansion module. The device can be configured in 4, I2C addresses using the 4, switches.
