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, then apply the protection.
The ‘Destination Protect’ button text is normally “Dest Protect” and when a selected MD
destination is protected, the button legend becomes “Dest Unprotect.”
MD Mode
In MD mode, when you select a protected MD destination with a button, the ‘Destination
Protect’ button goes high-tally.
To protect or unprotect MD destinations, select the destinations and press a ‘Destination
Protect’ button.
X-Y Mode
In X-Y mode, you may protect or unprotect the current destination on each of its levels.
Select the level(s) and press the ‘Destination Protect’ button to perform the protect. Select
protected levels and press the ‘Destination Protect’ button to unprotect them. A protected
level has a “P” next to it when it appears in the display.
See Lock, Protect, and Release on page 67.
P
Free Source
This button selects a phantom device that can be used to release or “free” devices on the
data (machine control) level. A free source can also be used with tielines to free the tieline
for others to use.
Use this button as if it were a source button.
The actual free source is configured in the Level Set Details page of NV9000-SE Utilities.
The default button text is “Free Source” but the button can have any legend.
Forward
Displays and activates the next button page in an automatically generated list.
A forward button is never high-tally. A forward button is generated by the system when a
list has more than 16 elements. Forward buttons are always accompanied by “back”
buttons.
