Description (under Server Mode)
During operation, the button has 3 functions:
1 Display a source category's device list when the panel is in source mode.
2 Display a destination category's device list when the panel is in destination
mode.
3 Present a suffix (or a digit) to be appended to a device name during category
selection.
Thus, when you configure a category button, it has 3 drop-down lists in the
button definition section: 'Src Category' , 'Dst Category' , and 'Suffix' . You
should choose a category from each category list. (You may choose 'None' in
either category list.)
The button definition section also presents a "level set filter" drop-down list
in which you can select a level set to reduce the number of categories
through which to browse.
Each category button displays 2 lines of text: (1) either the source category
name or the destination category name, and (2) suffix text, in that order. If
the button has no suffix text, the second line shows dashes.
When the operator first presses a category button, the category mnemonic
appears in the 'Preset' display. After the category is thus selected, the
operator uses a keypad (button array) to enter the device index within the
category. (The keypad is a set of category buttons to which indexes or
suffixes have been assigned.)
Pressing a category button when the panel is in source mode starts the
"construction" of a source device name. Pressing a category button when the
panel is in destination mode starts the "construction" of a destination name.
 Operators can also use the knob to scroll through sources or destina-
tions after choosing a category.
The default button text is the category name. You can override the default
text.
See Category List, on page 28.

Note that category buttons in server mode function differently from
category buttons under LCD XY/MD mode and NV9609 mode. There are
differences in the configuration of these buttons too.
When a chop function is supported by a router, the button is a toggle that
enables and disables rapid switching of the selected destination device
between the current source and the preset source. This chop function is used
to test system timing.
The button definition has no fields to configure. Its legend is arbitrary.
The button reverts to the most recent preset. You may think of this as a
"backspace key. " It erases the suffixes you entered under category select in
reverse order. Operators can press 'Clear' multiple times; each press is
another
