Button Definitions
Selection Buttons
 Selection buttons are available only when the panel is configured under the LCD XY/MD
model.
Operators use selection buttons to select levels when the panel is in X-Y mode and MD devices
when the panel is in MD (multi-destination) mode. Selection buttons also provide feedback
(e.g., source and destination mnemonics on the face of the buttons) when the operator is
performing takes.
A set of selection buttons supports (1) level selection in XY mode and (2) device selection in
multi-destination mode.
You should configure at least one selection button (for feedback). You may configure as many
selection buttons as are suitable for your system. For instance, if your system has a maximum of
12 levels for any device, it might make sense to have 12 selection buttons.
Operators can scroll through multiple pages of levels in X-Y mode and through multiple pages
of devices in MD mode.
Selection (of levels or MD devices) is affected by ‘Hold’ mode. 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.
Selection Button Behavior
X-Y Mode
When the panel is in X-Y 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.
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.
 Note that the maximum number of MD destinations is configured in multiples 8, from 8 to
512.
Populating the MD Device List
The ‘Edit Multi-Destination Device’ button appears when you are configuring a selection button.
Click this button to get the ‘Multi-Destination Entry’ window. The window presents a list of all
destinations on the left and a set of MD devices at the right. The MD device set is initially empty
