5. Operation
Operating Concepts
‘Source/Destination’ buttons are affected by the toggle. In source mode, a ‘Source/Destination’
button selects a source; in destination mode, a ‘Source/Destination’ button selects a destination.
When the panel is in source mode, the ‘Source/Dest Toggle’ button and any ‘Source/Destination’
buttons are green. When the panel is in destination mode, the ‘Source/Dest Toggle’ button and any
‘Source/Destination’ buttons are amber.
All Source Shift
The ‘Source Shift’ button toggles between the first and second source “pages.”
The button affects the operation of any source button (in any mode). Source buttons represent two
sources (and, in multi-destination mode, a destination). One source belongs to source set 1 and the
other belongs to source set 2.
All Undefined
An undefined button cannot be used and appears dark (unlit) on the panel. The term “undefined”
has meaning primarily to the configurer.
Lock, Protect, and Release
In a multi-user system, routes made by one user can be made safe from being accidentally or mali-
ciously change by another user.
Definitions
Owner The user ID of a panel where a lock or protect was issued.
Source lock No one can use the source.
Source protect No one but the owner can use the source.
Destination lock No one can route to the destination.
Destination protect No one but the owner can route to the destination.
Release To remove a lock or protect.
Some control panels can lock or protect both sources and destinations. However, The NV9602 pro-
vides locks and protects for destinations only .
A forced release is when the lock or protect is removed by someone other than the owner. A forced
release can be performed:
• At any panel configured with release mode set to “forced release”.
• At any other panel with “force release” enabled.
The ‘Destination Lock’ and ‘Destination Protect’ buttons are toggles. Press the lock (or protect)
button to lock (or protect) a destination. Press the button again to release the lock (or protect).
S
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.
S
You may lock a protected destination, but you cannot change a locked destination to a protected
destination directly. You must first unlock it.
Locks and Protects with Breakaway
Use this method to lock or unlock selected levels in single-destination mode with breakaway:
1 Verify that the default destination appears in the ‘Destination’ field of the display.
2 Optionally press ‘Source Shift’ to toggle between the source pages.
