Operation
Operating Concepts
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 49 for more information.
 Pressing the ‘Broadcast’ button turns off the ‘Source is Master’ button and vice versa.
Category
A category button selects either a category mnemonic or a category suffix. Category buttons
exist for the purpose of selecting (i.e., naming) either a source or a destination device.
When you have not started a device selection, pressing a category button (1) chooses a cate-
gory mnemonic as the beginning of a device name and (2) starts the device selection.
Thereafter, pressing a category button appends the suffix represented by the button to the
device name. When you have constructed the device name of choice, you simply stop pressing
suffix buttons.
A category button operates in source mode or destination mode. In source mode, it selects a
source category or a suffix for the source category. In destination mode, it selects a destination
category or a suffix for the destination category.
When the panel is in source mode, category buttons that are not configured with a source cate-
gory become disabled. When the panel is in destination mode, category buttons that are not
configured with a destination category become disabled. Category buttons configured with
both source and destination categories are not disabled in either mode. Category buttons that
have only a suffix configured are disabled until a category becomes selected.
There are fixed and optional category buttons. The fixed category buttons form a keypad within
the array of function buttons at the right:
The keypad is also used under menu mode and under setup mode.
 You cannot perform a name set change using a ‘Nameset Toggle’ button while a category
selection is in progress.
 See also Category Buttons for Rapid MD Device Selection on page 38.
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.
