Operation
Operating Concepts
Category
A category button either (1) causes the display of a category’s device list or (2) displays a “suffix
page.” See
Global Navigation on page 44. A category button represents either a source category
or destination category.
The button text is normally the category name, but the configurer can give it any text. Category
names tend to be short.
It is a common convention that buttons for source categories and devices are green and buttons
for destination categories and devices are amber. The NV9654 follows this convention.
Device List
When you press a category button, the NV9654 displays the first of perhaps several pages of
device buttons. You can scroll the pages using back and forward buttons. If you press ‘Back’
while on the first page of the list, the NV9654 returns to the page containing the category
button.
Suffix Page
When you press a category button that produces a suffix page, the NV9654 displays the suffix
page which will contain buttons forming a numeric keypad, other buttons that represent alpha-
numeric suffixes and perhaps a few other buttons. Use the keypad to enter an index or suffixes
of a device within the category. If you make a mistake, press the ‘Clear Preset’ button and try
again.
When you have finished entered an index or suffixes, press either the back button or the take
button if present. The panel will have tracked your entries by concatenating the index or suffixes
to the current destination name (for a destination category) or to a preset source name (for a
source category).
While you are pressing digits to enter an index, some of the numeric buttons can become
disabled. They do so because there are no further categories that can be selected using those
buttons. For example, if you have 14 devices in a category, numbered 1–14, after you press the
digit 1, digits 5, 6, 7, 8, and 9 go dark. The digits 0–4 remain because they can be part of a valid
index.
The same is true for suffixes: if a suffix cannot be used for a device name, it is disabled.
 Keep in mind that device names are limited to 8 characters.
 A keypad normally has 10 buttons, 0–9. However, it is possible for a suffix page to have fewer
buttons.
Chop
When a “chop” function is supported by a router, the button is a toggle that enables and
disables “chop.” Chop is a rapid switching of the selected destination device between the
current source and the preset source.
The chop function is used to test system timing and would not be used during normal
operation.
The default button text is “Chop” but a chop button can have any legend.
Select a preset source and press ‘Chop’ to start the chop function. Press ‘Chop’ again to stop the
chop function.
