You can change the name of a page by double-clicking the page's name field and editing its
text. Changing the name of a page does not cause a change to the caption of the navigation
button and vice versa.
During configuration, you will use 'Navigate' buttons to create new pages. During configuration,
you can double-click a 'Navigate' button to jump to its page.
During operation, panel operators will press navigation buttons, global navigation buttons, or
category buttons to jump to other pages.
Navigation buttons do not jump to global suffix pages or global navigation pages. Only
global navigation buttons jump to global navigation pages; only category buttons jump to
suffix pages. However, the operator will probably see no appreciable difference between the
button types. See
When you double-click the page number field of a page you want to edit, the image of that
page appears in the panel graphic area.
The "Links to Page Num(s)" column lists, for any page, the other pages that refer to it. Using the
links column you can mentally examine the tree structure or create a sketch of the tree struc-
ture. You might note that if the link field of a page is empty, the page is inaccessible during
operation. (The exception is the default page which is always available after reset. It might
become unavailable in a configuration that has subpages with no 'back' buttons.)
Tally (GPIO) Window
Below the tree window is the tally section of the configuration page.
It has two sections: inputs and outputs. By clicking on one of the input or output buttons, you
can configure the input or output.
(The NV9640 has no actual tally buttons. These buttons represent the DB25 connector at the
rear. The buttons are present in the configuration page to allow you to configure the tally
interface.)
If you are interested in configuring the tally interface, read Chapter 6, GPIO, on page 75.
Selection Buttons
Selection buttons have many functions, not the least of which is to provide feedback (e.g.,
source and destination mnemonics on the face of the buttons) when the operator is performing
takes.
Selection buttons support level selection in XY mode and device selection in multi-destination
mode.
You should configure at least one selection button (for feedback). You may configure as many
selection buttons as are suitable for your system. For instance, if your system has a maximum of
12 levels for any device, it might make sense to have 12 selection buttons.
