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 entering 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, and may have some number of buttons
assigned to alphanumeric suffixes. However, it is possible for a suffix page to have
fewer buttons.
When you press a category button, the NV9641 displays the first of perhaps several pages
of device buttons. You can scroll the pages using the up and down buttons. If you press ‘Up’
while on the first page of the list, the NV9641 returns to the button page containing the
category.
The button text is the category name. Category names tend to be short.
It is an Grass Valley convention to use green for source category buttons and amber for
destination category buttons.
Chop
When a “chop” function is supported by the router, the button is a toggle that enables and
disables chop: 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.
Clear Preset
The ‘Clear Preset’ button erases all preset entries (while leaving the panel in the same
mode). It is generally a “safety” feature.
The clear preset button has the side effect of switching off ‘Save Preset’ mode.
The default button text is “Clear Preset” but the button can have any legend.
