Operating CR6400 Routers
Stand-Alone CR6400 Network
When the control panel is locked, the Panel Lock button is bright red and the state of the entire
control panel is protected. Changes from the control panel are disabled. The ‘Panel Lock’ button
is low tally green when the control panel is not locked.
 Remember that a ‘Panel Lock’ button locks that panel only. It does not lock any router, other
control panels, or the network.
Destination Lock
Destination lock prevents an operator from selecting another source for the currently selected
destination. In a network, sources and destinations comprise one or more levels. When you lock
a destination, it is locked on the levels you select. And when you unlock a destination, it is
unlocked on the levels you select.
 To unlock the destination completely, you must select exactly the levels on which it was
locked. But, after you lock a destination on levels, it is difficult to remember on which levels
you have locked it.
To lock a destination,
1 Press level buttons on a panel to select the intended levels.
The following illustrations show a system that has 3 levels (1–3), two of which are selected.
Buttons for selected levels are high-tally.
2 Press ‘Destination Mode’.
3 Press the selection button for the destination you want to lock.
4 Press ‘Destination Lock’.
This sample shows destination 5 locked on levels 2 and 3, but not level 1:
When you press ‘Destination Lock’, immediately goes high-tally red and the selection button for
the destination goes high tally red. Changes to that destination are disabled on all selected
levels. If you subsequently press a destination button that is locked, the button goes high tally
(red), and the Destination Lock button goes high tally, as this sample shows.
Changes to other destinations remain enabled and other destinations remain unchanged,
whether locked or unlocked. Note that you can route the source that feeds a locked destination
to any number of other destinations.
