# I/O Ports tab (only with GPIO)

**NOTE**This tab is displayed only if the Nodegrid device is equipped with GPIO (Digital I/O ports).

This sets the configuration of the state of digital outputs and DIO0/DIO1 as input or output. When DIO0/DIO1 is configured as output, the state can be set to Low or High. ![](https://cdn.document360.io/763c5fb1-b9af-4ccd-9ad6-cf28ae4cd5a3/Images/Documentation/image-1678373630466.png)
