Selection
XY Mode — Normal
When the operator selects a destination, all selection buttons that have levels defined for the
destination turn on (high-tally). The operator may select or deselect any levels as required, by
pressing selection buttons and perhaps scrolling the display.
Note that if the operator selects a level when all levels are on, all the other levels become
unselected (low-tally).
Selecting a new destination again turns on all selection buttons that have levels defined.
Source/Destination buttons are "all level"— not subject to level selection.
XY Mode — Hold Mode
In hold mode, when the operator selects a destination, previously deselected levels (defined for
the destination) remain selected for additional takes and previously unselected levels remain
deselected. (Individual levels turn on or off as the user selects them.)
MD Mode — Normal
When the user selects an MD device, all selection buttons are mutually exclusive: when the
operator presses one button, any others that were selected turn off. To perform MD takes, the
operator alternately selects an MD device and then a source until all intended devices have
been preset. Then the operator presses 'Take' .
(In normal mode, any selected MD devices become unselected after the take.)
MD Mode — Hold Mode
In hold mode, selection buttons are not mutually exclusive. To perform MD takes, the operator
selects one or more MD devices. All of them turn on (high-tally). The operator then selects a
source (which becomes preset for all the selected devices).
The operator can preset another source to another set of destinations by deselecting selected
destinations, selecting other destinations, and selecting another source.
When all intended destinations are preset, the operator then presses 'Take' .
(In hold mode, the MD devices remain selected after the take.)
Configuration
You can configure selection buttons on any of your button pages. During configuration, when
you assign a selection button, an additional drop-down menu appears: 'Display Index' .
The drop-down menu for the button's display index has exactly 8 entries — one for each line of
the alphanumeric display.
The display index identifies one of the lines in the display. Assigning a display index to a selec-
tion button makes it correspond to the line of the display.
The range of display indexes corresponds to the number of selection buttons, but the
maximum range is 1–8. More than 8 selection buttons is useless.
1. The term display index means something quite different on certain other panels such as the NV9641.
