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.
During configuration, you can prescribe NV9640 behavior that depends on the tally inputs.
What you connect to the tally interface is, of course, up to you. Grass Valley provides a breakout
cable (WC0053) for the tally connector as a purchase option.
The NV9000-SE Utilities on-line help documentation calls the tally interface a GPIO interface. On
the rear of the panel, it is labelled a "GPI interface. "
See Chapter 6, GPIO, on page 75, for complete detail.
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
"button-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
destinations and sources. You can scroll through destination lists using the 'Up' and 'Down'
buttons. Select a destination using selection buttons, choose a source, and repeat for all
desired routes. Then press 'Take' . Takes are "all level, " and breakaways cannot be performed.
A '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 NV9640. It can be combined with the other
two modes. You can create many different forms of "single-destination" mode.
To understand single-destination mode, you must understand the different button types.
Please read the Configuration and Operation chapters and then see
Mode
The secondary modes of panel operation are:
•
Setup mode — where the NV9640 is freshly powered up, but disconnected from the net-
work. In this mode, you can preset the NV9640's panel ID and perform a few diagnostic tasks.
•
Salvo mode — pressing a Salvo button (and then the 'Take' button) executes a salvo. (The
duration of a salvo is indeterminate.)
•
Menu mode — pressing a Menu button places the NV9640 in "menu" mode. In menu mode,
the LCD button array becomes a menu that changes as needed during menu operation.
Other modes of operation are:
•
Hold mode — when you press the 'Hold' button, hold mode becomes active and when you
press it again, hold mode becomes inactive. See
•
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. See
page 62.
