User’s Guide
 You cannot perform a name set change using a ‘Nameset Toggle’ button while a category
selection is in progress.
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.
The default button text is “Chop” but a chop button can have any legend.
Select a preset source and press ‘Chop’ to start the chop function. Press ‘Chop’ again to stop the
chop function.
Clear Preset
The ‘Clear Preset’ button removes any preset entries.
The default button text is “Clear Preset” but the button might have any legend.
Default State
This button returns the NV9649 to its most recent power-up state. You may consider this button
an emergency button or a “soft reset” button.
 This button does not affect any previous routes. Only the panel itself is reset.
The default button text is “Default State” but the button might have any legend.
Destination
The button selects a destination. The destination name appears in the ‘Destination’ display. The
destination is the target of an upcoming take, which will route a source to that destination.
Pressing a destination button has two side effects: it clears — or partially clears — the ‘Preset’
display, and (2) it turns off the ‘Take’ button if it is on.
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.
