Flags; Tally Interface - GRASS VALLEY NV9640 User Manual

Introduction
Panel Organization
In X-Y mode, the preset column represents the levels of a source or the levels of multiple
sources under breakaway. These are called the preset source(s). After the take, they disappear
from the preset column and re-appear in the status column, reflecting that the preset
sources have now become current sources.
In MD mode, the preset column indicates the sources that will be routed to selected destina-
tions in the 'Level/Dest' column. These are the preset source(s). After the take, they disappear
from the preset column and re-appear in the status column, reflecting that the preset
sources have now become current sources.
•
Information (not labeled).
The first entry in this column is "X - Y" or 'MultiDest" unless you have entered salvo mode,
menu mode, or setup mode. See chapter 5 for those topics.
The bottom-most entry in this column is always the page number of the display.
In X-Y mode, the second entry is always the word "Dest" as a title for the third entry which
identifies the current destination. In the preceding illustration, the current destination was
VTR--1.
In MD mode, there are no entries in this column other than "MultiDest" and the page num-
ber.
The display fields can show either names from a name set or system mnemonics for devices
depending on (1) the state of the 'Name Set Toggle' button (if the panel has one), (2) the default
name set (3) the existence of name sets in the NV9000 configuration. (An alias is a name defined
in a name set.)

Flags

The display also shows flags of different kinds next to the sources and destinations.
Selection Marks
At the far right of the display are marks (3 small bars) that turn on to indicate selections.
In X-Y mode, the marks turn on to indicate that a level is selected and are not visible otherwise.
(The operator makes level selections in the button array.)
In MD mode, a mark appears to the right of the currently selected destination (and of all the
currently selection destinations in hold mode).
Other Signs
A plus sign (+) indicates that additional information is available. There is an 'Info' button that
operators may press to view the additional information.
In MD mode, an asterisk (*) directly after a source indicates a breakaway on that destination.
An 'L' indicates that a device has been locked. A 'P' indicates that a device has been protected.
NV9640 operators may lock, protect or release destinations. It is important for operators to
know that other operators may lock, protect, or release sources and destinations.

Tally Interface

At the rear of the panel is a DB25 connector that provides 8 tally inputs and 4 tally outputs. (The
outputs are solid state relay outputs.) Both inputs and outputs are optically isolated.
