Operation
Operating Concepts
 ‘Name Set Toggle’ buttons are disabled while a category selection is in progress.
 The panel requires that category/suffix device selection be performed using the names in
the system name set. However, it displays the device you selected using the active name set.
We recommend that you switch to the system name set prior to category/suffix device selec-
tion and return to your preferred name set afterward.
Navigate
A navigate button displays and activates one of the button pages defined in the panel configu-
ration. We call that the “target” button page.
The target page can be an ordinary button page (defined during configuration) or it can be the
first page of a list. Lists are characterized by “back” and “forward” buttons on the panel. Such
lists can be categories (source or destination), sources, destinations, or salvos.
Navigate buttons have no specific default text and it is the configurer’s job to provide text that is
meaningful. The text should help identify the contents of the target page.
Just press the navigate button to access the target page.
Other kinds of buttons can cause the display of a target page. These include ‘Global Navigate’
buttons and category buttons. In practice, navigate buttons, global navigate buttons, and cate-
gory buttons are nearly indistinguishable, although the pages they display can be quite
different.
See the Category button type.
Global Navigate
A ‘Global Navigate’ button functions the same way a navigate button does. Global navigate
buttons exist mainly for the convenience of the configurer. Operators should rarely notice any
difference between global navigation buttons and other navigation buttons.
Global navigate buttons, however, can access only static button pages. They do not access list
pages. That is because configurers have no list options for global navigate buttons.
Page Down
This button scrolls a list of levels in X-Y mode or a list of MD devices in MD mode. There are 3
options for scrolling:
1 Scrolling the display only. The items on the selection buttons do not scroll.
2 Scrolling the selection buttons only. The items on the display do not scroll.
3 Scrolling both the display and the selection buttons at the same time. This behavior can
occur only when the panel has no ‘VFD/Sel Paging Toggle’ button.
If the panel has a ‘VFD/Sel Paging Toggle’ button, you can switch between options 1 and 2. The
button will read either “Paging VFD Display”[sic] or “Paging Select Buttons.”
When you scroll the selection buttons, they scroll modulo the number of buttons. For instance, if
there are 9 buttons, they scroll in groups of 9 items.
This button scrolls the list down. Down means toward the end of the list of scrolled items, or in
the direction of increasing numbers. The ‘Page Down’ button becomes enabled when it is
possible to scroll down and is disabled when it is not possible.
The default button text is “Page Down” but the button can have any legend.
