Configuration
Button Types
Page Down The button scrolls down through the device list of the currently selected
category.
The device selected appears in the ‘Preset’ field of the display.
 The term “page” does not have any meaning here.
‘Page Down’ moves to the next lower device in the category’s device list.
(Example: if the current device is CAM_4, the next lower device would
probably be CAM_3, subject to the device definitions in the NV9000
configuration.)
Scrolling devices is possibly only when a category selection is in progress.
Whether the list wraps around at the beginning or end is governed by the
‘Use Continuous Scrolling’ panel option.
The button definition has no fields to configure.

category.
