B. Control Panels
NV9642
Tally Interface
At the rear of the panel is a DB25 connector that provides 8 tally inputs and 4 tally outputs. Both
inputs and outputs are optically isolated.
During configuration, you can construct Boolean logic that switches the outputs on. The terms of
the logic expressions are states of the source and destination devices, etc., controlled by the
NV9000 control system.
Modes of Operation
The panel operates in either X-Y mode or multi-destination (MD) mode. A single button ( XY/MD )
can toggle between the modes. A third mode — called “single-bus,” “single-destination,” or “but-
ton-per-source” mode — can be emulated in either X-Y mode or MD mode.
The primary modes of operation are:
• X-Y mode — individual control of all router levels. Choose a destination, optionally choose
desired breakaway levels, choose a source, and press Take to complete a desired route.
• Multi-destination mode — lets you control multiple destinations. The LCD buttons display des-
tinations and sources. You can scroll through destination lists. Select a destination using selec-
tion buttons, choose a source, and repeat for all desired routes. Then press
Take
. Takes are “all
level,” and breakaways cannot be performed.
• The alphanumeric display scrolls independently of the selection buttons. Use the fixed up/
down buttons to scroll the display.
• The
Hold
button allows you to select many MD destinations at once.
• Single-destination mode.
Single-destination” mode is not a distinct mode, but we mention it because it is a mode on some
other panels and can be simulated on the NV9642. It can be combined with the other two
modes. You can create many different forms of “single-destination” mode. This mode may in
fact have more than a single destination.
The secondary modes of panel operation are:
• Setup mode — where the NV9642 is freshly powered up, but disconnected from the network. In
this mode, you can preset the NV9642’s panel ID and perform a few diagnostic tasks.
• Salvo mode — pressing a Salvo button (and then
Take
) executes a salvo. (The duration of a salvo
is indeterminate.)
• Menu mode — pressing a Menu button places the NV9642 in “menu” mode. In menu mode, the
LCD button array becomes a menu that changes as needed during menu operation.
• Hold mode — when you press the
Hold
button, hold mode becomes active and when you press it
again, hold mode becomes inactive.
• Save preset mode — when you press the
Save Preset
button, ‘Save Preset’ mode becomes active
and when you press it again, ‘Save Preset’ mode becomes inactive.
Other Functions
The NV9642 can be configured to perform the following additional functions:
• Previous source, free source, “quick” source, and source/destination buttons.
