How to use a GPIO as Input

You can use one or more of the IO's as an Input in order to trigger any sequence or event in Neets Project Designer. It might be an external button or switch which enables an event in the controller, like combining two rooms and locking buttons on the slave room.

An input can trigger in two different ways, high or low. 

In the schematic below, you can see that the controller accepts voltages up to 24 volts and a short to ground.

In the Systems page of Project Designer you assign one of the IO's as an Input as shown below:

Then go to the Feedback section and give the input a function as shown here:
