Locks
A “lock” prevents anyone — even the user who issued the lock — from routing to the destination or
source. A “protect” prevents others from routing to a destination or source, but not the user who
created the protect. Locks and protects are useful for preventing accidental routes. For more infor-
mation on “protects”, see
Protect on page 45.
Locking a destination prevents any user, including the panel’s owner, from switching the locked
source to any other device. Similarly, locking a source prevents any user, even the panel owner,
from routing from a source device any destination.
Locks are applied by an “owner” of a panel. The owner is identified by the User Name. To users of
other control panels, when a device is locked a “+” appears in the ‘Preset’ column in the display
area. The user can press
Info
to learn which user applied the lock (see Information on page 40). If a
lock was applied by the current user of a control panel, no “+” displays. To remove a lock applied
by another user, Forced Release mode must be enabled. For instructions, see
Force Release on page
39.
The ‘
Dst Lock
and ‘
Lock
buttons are toggles. Press the button to lock a device. Press the button again
to release the lock. In addition to having a Lock button on the control panel, Lock mode must be
enabled in the Panel Options (‘Enable Source Lock’; ‘Enable Destination Lock’) (see NV9000-SE
Utilities User’s Guide).
Locking and Unlocking Sources
How a source is locked depends on whether you are in X-Y or MD mode. Only the user that
applied the lock can remove it unless Forced Release mode has been enabled (see
Force Release on
page 39). Once locked, the source cannot be routed to any destinations until the source is unlocked.
When a lock is applied to a source, the following displays:
• ‘L’ in ‘Status’ column when the lock is initially set by owner at owner’s panel.
• ‘L’ in ‘Preset’ column when source is preset by owner at owner’s panel.
• ‘L+’ in ‘Preset’ column when lock set by another user.
• ‘I’ appears if applying a lock to a machine control (data) device indicating that an implicit lock
has been applied.
