Operation
Button Functions
Destination Mode
The button places the panel in destination mode. Category selections in destination mode
select destination devices. Category buttons that are not configured with destination categories
become disabled.
Destination devices are represented on the ‘Destination’ display.
Categories that include both source and destinations appear in both source mode and destina-
tion mode.
Destination Lock
This button is a toggle that sets or clears a lock on the current destination. The lock can be
removed at the panel that originally set the lock, at a panel that has the same user ID, or by a
forced release at any panel.
 The NV9649 provides no explicit indication, during operation, whether a destination is
locked or unlocked.
Destination Protect
This button is a toggle that sets or clears a protect on the current destination device. The protect
can be removed at the panel that originally set the protect, at any panel that has the same user
ID, or by a forced release at any panel.
 Note: a protect prevents others from routing to a destination; a lock prevents anyone — even
the user who issued the lock — from routing to the destination.
 You may lock a protected destination, but you cannot change a locked destination to a
protected destination directly. You must first unlock it.
 The NV9649 provides no explicit indication, during operation, whether a destination is
locked or unlocked.
Free Source
The button selects a pre-defined phantom device that can be used to release or “free” devices
on the data (machine control) level. A free source is also used with tielines to free the tieline for
others to use. The actual free source used is defined in the NV9000 configuration.
Use this button as if it were a source button.
Level
The button selects a level. If the button’s level is not defined for the current destination, the
button is disabled however.
Level buttons are not available in level mode. A level is selected differently in level mode.
If the panel has multiple level buttons, operators can select multiple levels. When all level
buttons are deselected, a take is “all-level.” When one or more level buttons are selected, a subse-
quent take occurs on those levels.
You must select level(s) before selecting the source, otherwise the level selection does not work
and the take will be all-level.
The color of the level buttons reflect the levels of the current destination in a limited way. (With
just two colors, it is not possible to represent all possible combinations of sources taken to a
