Configuration
Selection Buttons
If the panel has a ‘VFD/SEL Toggle’ button, operators can switch between options 1 and 2. The
button will read either “Paging VFD” or “Paging Sel Buttons.”
Selection (of levels or MD devices) is affected by ‘Hold’ mode. (See the Information button,
page 27.) 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 Panel Options .
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 selec-
tion 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 ‘Page Up’ and ‘Page Down’ buttons activate
and the operator can scroll through the levels.
MD Mode
When the panel is in MD mode, a set of selection buttons presents a set of MD devices.
If a selection button is blank, an MD device was not assigned to it. If a selection button is high-
tally, the MD device is selected. If a selection button is low-tally, the MD device is not selected.
(Perform MD destination population by clicking lines in the image of the display and scrolling
when necessary. See
Multi-Destination Configuration on page 38.)
If there are more destinations than selection buttons, the operator can scroll through the desti-
nations using ‘Page Up’ and ‘Page Down’ buttons. Including those buttons on the button page
that has the selection is strongly recommended.
S
Note that the maximum number of MD destinations is configured in multiples 8, from 8 to
512.
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.
S
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.
S Source/Destination buttons are “all level”— not subject to level selection.
