Operation
Buttons for the NV9609 Model
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.
The NV9649 provides no explicit indication, during operation, whether a destination is
locked or unlocked.
Free Source
The button selects a pre-defined phantom device that can be used to release or "free"
devices on the data (machine control) level. A free source is also used with tielines to free
the tieline for others to use. The actual free source used is defined in the NV9000
configuration.
Use this button as if it were a source button.
Level
The button selects a level. If the button's level is not defined for the current destination, the
button is disabled however.
Level buttons are not available in level mode. A level is selected differently in level mode.
If the panel has multiple level buttons, operators can select multiple levels. When all level
buttons are deselected, a take is "all-level. " When one or more level buttons are selected, a
subsequent take occurs on those levels.
You must select level(s) before selecting the source, otherwise the level selection does not
work and the take will be all-level.
The color of the level buttons reflect the levels of the current destination in a limited way.
(With just two colors, it is not possible to represent all possible combinations of sources
taken to a destination.) If the destination has breakaway levels, some of the level buttons
will be amber; some will be green. Otherwise, they will all be green.
If you want to examine the levels of a destination, press 'Level Mode' and scroll through the
levels. The 'Status' display shows the source for each individual level as you scroll and shows
whether the source is a breakaway source.
Level Mode
The 'Level Mode' button toggles the panel in and out of level mode. "All Level" appears in
the 'Info' display when level mode is turned off.
Level mode allows operators (1) to examine the levels of the current destination and (2) to
perform single-level takes.
Source buttons and destination buttons, and several other button types, are disabled in
level mode. The only means to select a source in level mode are source category buttons.
