# System Overview

The I/O Hub Software consists of three parts:

- I/O Hub Settings

- I/O Hub Web Interface

- Internal Web Pages

## I/O Hub Settings

I/O Hub Settings is used to find and configure all I/O Hub devices connected to the network, and to update device firmware and ARGEE program. To access I/O Hub Settings, contact your local Atlas Copco Service Technician or Sales Representative.

The default password for I/O Hub Settings is password.

## I/O Hub Web Interface

I/O Hub Web Interface is used to configure settings for communication between controller and I/O Hub device. I/O Hub Web Interface is accessed through I/O Hub Settings by selecting the device IP address in the IP address column, or by searching for the IP address of the I/O Hub device in a web browser (I/O Hub IP address/hmi.html Ex: http://169.254.1.254/hmi.html).

## Internal Web Pages

The Internal Web Pages are accessed through I/O Hub Web Interface. It is recommended to contact your local Atlas Copco Service Technician or Sales Representative if any changes are wanted there. Note that changing these setting may permanently affect the functionality of the I/O Hub 8-PS. You are solely responsible for any settings changes implemented without the authorized support from Atlas Copco.
