# GPIO Connector Pinout for Omnia.9

## Scope

This document provides the pinout for the rear panel GPIO DB25 connector.

## Question

What is the pinout for the rear panel DB25 GPIO connector?

## Answer

There are 8 GPI's and 2 GPO's.

Pins 2 through 9 are GPI inputs 1 through 8.

Ground is at Pins 13, 23 and 25.

GPO A is at pin 24, and GPO B is at pin 12.

+5V is at pin 1 and pin 14.

You can program pretty much any function to GPIO using the Task Script feature. This is described in the latest version of the manual in chapter 23 starting on Page 186. You can also download the NfRemote app from this page.
