NORVI EX-F16 – USER GUIDE

Programming #

NORVI-EX-F16 uses MCP23017T-E_SO over I2C communication. The I2C addresses of the devices can be configured with the DIP switches at the bottom of the controller.  It can Daisy chain up to 8 expansion modules.

Expansion Port #

The expansion port of the NORVI IIOT Controllers can be utilized for external sensor connections where raw GPIO connections are required, or they can be used to plug NORVI Expansion Modules. Browse the NORVI Expansion Product Range. How to Connect NORVI Expansion Modules

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, the I2C address of the expansion module can be configured by switching DIP switches at the bottom of the expansion module. The device can be configured in 2 I2C addresses using the 4 switches.
