Button Specification - GRASS VALLEY NV9649 User Manual

The set of button functions for the 3 behavioral models differ greatly.
There are four classes of button functions:
• Dedicated functions, such as 'Default State' or 'Chop' .
• Variable functions, such as 'Category' or 'Source' . With this type of button, additional
selections are needed to complete the button configuration.
• Special functions, such as 'Navigate' and 'Back' . These functions allow the panel
operator to move from one button page to another. (The Navigate button is unique: it
initiates a dialog in which you create a subtree.)
• System-generated button functions. These are buttons that are generated dynamically
(by the router control system) during operation. An example of system-generated
buttons is a device list generated when the user presses a category button. The set of
devices in a category can change over time (as the configuration database changes);
the NV9649 device list changes also.
The number and names of categories can also change over time and the NV9649 will
track those changes too.

Button Specification

The button definitions section has several controls:
The controls vary according to the button type.
Button Type
Button Caption
Note:
Certain button fields contain a colon (:) and number after the data in the field. The
number is the record ID of the object in the NV9000 configuration database. The record
IDs can be ignored but might be of some use when the configurer is searching for items
in the configuration database.
A pull-down menu where you may select a button type.
Three text boxes in which you can enter three lines of button text up to
8 characters each. SE provides a default for the button caption.
Some buttons do not allow you to enter button text. Category buttons,
for example, use the category name as the button text.
