Set the context to the device you want to work with.
Click the Controls panel's header to open the panel.
The writable properties of the device are listed. If the device has
components, the properties will be organized under their respective components.
Locate each property you want to set and select its check box. (Alternatively, you can select the Select All check box in the header to select all properties.) For each selected property, type a value in the corresponding text field, set the value with the slider, or select a value from a drop-down list, whichever is applicable to the property.
Then click Update
