want. The new position will be indicated by a slightly heavier black line. The row you
selected is re-positioned where the black line is when you release your mouse button.
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 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 '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
destinations using 'Page Up' and 'Page Down' buttons. Including those buttons on the
button page that has the selection is strongly recommended.
