# Updating Operating System The Control Hub’s Operating System is field upgradable. New updates are released to incorporate fixes, improvements, and new features as they are developed. There are two ways you can update the Operating System. It is recommended to use the [REV Hardware Client](#using-the-rev-hardware-client) as it will automatically notify the user if the Hub's Operating System is out of date, download the latest OS, and install the OS on the device. The second way utilizes the FIRST Robot Controller Console. For using the FIRST Robot Control Console, you will need to download the latest Operating System. [Download the Control Hub OS Version 1.1.6](https://github.com/REVrobotics/REV-Software-Binaries/releases/download/chos-1.1.6/controlHubOS-1.1.6.zip) {% hint style="info" %} Updating the Operating System can take some time depending on the size of the update. Expect the update to take approximately 5 minutes to fully complete and keep the Control Hub powered during this process. {% endhint %} {% hint style="warning" %} The following procedure works with Control Hubs with the part number REV-31-1595.

The Control Hub is ready to connect with a PC when the LED turns green.

Note: With Robot Controller Application versions 5.5 and below the light will blink blue every \~5 seconds. Please update to 6.0.
