NORVI-EX-Q16 User Guide

Programming #

NORVI-EX-Q16 uses MCP23017 over I2C Communication. The I2C Address of the devices can be configured with the DIP Switches in the bottom of the controller.

Programming Transistor Outputs

Writing HIGH to the relevant GPIO of MCP230008 turns ON the Transistor output.

Refer to the GPIO Allocation Table for Transistor Output GPIO

Refer to the I2C Address setting to set the I2C address of the Expansion
