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, 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 Controller Console, you will need to download the latest Operating System.
Steps
Start up the REV Hardware Client 2. Once the hub is fully connected, it will show up on the front page of the UI under the Hardware Tab. Select the Control Hub.
After selecting the connected device, the Navigation Tab will pop up. Select the Update Tab on the right, highlighted by the orange box.
Once in the Update Menu, confirm the desired Control Hub OS version, then click the Install Button below.
Keep the Control Hub powered while the update is installing. The Control Hub will reboot to complete the update.
Once it reboots, you'll see a green Update Complete banner at the bottom, meaning the update was successful.
