Operation
Operation
At present, there are 35 button types, not including “undefined” which is not a true button type:
Back
Redisplay the previous button page. (The previous buttons become active.)
A back button may have any legend and be any color, but typically its legend is just “BACK” and
typically, its color is blue, as for back buttons generated automatically for lists. A back button is
never high-tally.
A back button has no effect on the contents of the alphanumeric display.
See also Forward .
Broadcast
A broadcast button applies to a data (or machine control) level only. The button assigns one
controlling device (the master) to multiple controlled devices (the slaves). The function is useful
in dubbing applications. See
Broadcast Routes on page 67 for more information.
 Pressing the ‘Broadcast’ button turns off the ‘Source is Master’ button and vice versa.
The default button text is “Broadcast” but a broadcast button can have any legend.
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 40. 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.
Device List
When you press a category button, the NV9640A 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 NV9640A returns to the page containing the category
button.
