# Software

The version number of two versions of software available in the Power Focus XCPower Focus XC controller are under the Software tab.

Installing a second version of the controller software is useful when performing upgrades on multiple controllers. When production is ready for switching to the upgraded software, activation of the new software version is done locally on the controller GUI, from a remote computer with the web GUI, or with Tools Talk.

A new software distribution can be installed either by connecting a USB flash drive containing the software to the controller’s USB port, or by using the web GUI.

The software update option is visible only when accessing the controller GUI from a PC. When a mass storage device with a valid software version is inserted in the USB port a prompt to update the software will appear.

The software update file must not be unzipped and must be stored in a folder named PFImages in the root directory on the USB flash drive.

An unexpected failure during software upgrade might lead to loss of data.
Before upgrading software versions, it is recommended to take a backup of the controller configuration by exporting “All controller information”.
