To select the controllers to update:
In the tree, select the controller(s) you want to update. You can also choose the controllers you want to omit from the update process.
All controllers of the same type are selected by default. If the controller software is already up-to-date, it is grayed out. To remove a controller from the selection, just click it.
Note! To force a controller to be updated, for example, if you want to down-level the software, press the Control key, then click the controller.
When you are ready to continue, click Next.
The Update summary window opens.
