Tally (GPIO) Window
Tally (GPIO) Window
Below the tree window is the tally section of the configuration page.
It has two sections: inputs and outputs. By clicking on one of the input or output buttons, you can
configure the input or output.
(The NV9642 has no actual tally buttons. These buttons represent the DB25 connector at the rear.
The buttons are present in the configuration page to allow you to configure the tally interface.)
If you are interested in configuring the tally interface, read Chapter 6,
, on page 63.
Selection Buttons
Selection buttons have many functions, not the least of which is to provide feedback (e.g., source
and destination mnemonics on the face of the buttons) when the operator is performing takes.
You should configure at least one selection button (for feedback) and up to 8 selection buttons (on
any particular button page) if you want to support level selection in XY mode or MD device selec-
tion in MD mode.
S
Scrolling with ‘Page Up’ and ‘Page Down’ buttons advances MD device lists or X-Y level lists
modulo the number of selection buttons appearing on a button page.
S
It is possible, but not recommended, to place more than 8 selection buttons on a page. The
result might be confusing, but it is otherwise harmless.
Selection (of levels or MD devices) is affected by ‘Hold’ mode. (See the
button,
page 26.) The user may toggle Hold mode at any time. Using the selection buttons follows hold
mode or normal mode, whichever is in effect at the moment. Normal mode is the default
—
unless
you specify otherwise in the
.
Selection Button Behavior
XY Mode
When the panel is in XY mode, a set of selection buttons presents a set of virtual levels. The levels
displayed on the buttons correspond to the levels in the level set of a selected destination device. If
a selection button is dark and blank, the level does not exist in the level set. If a selection button is
dark, but has text, the level exists, but is not defined for the selected device. If a selection button is
high-tally, the level is selected. If a selection button is low-tally, the level is not selected.
If there are more levels than selection buttons, the operator can scroll through the levels using ‘Page
Up’ and ‘Page Down’ buttons. The levels list scrolls module the number of selection buttons as
long as the number of selection buttons is 8 or less.
S
The up/down buttons next to the display scroll the display only.
