4.11. PRESET CONFIGURATION ITEMS
The 7725DSK-LG has 10 user presets that can store pre-defined configurations for such things as
Matte settings, Transition settings and DSK settings. The parameter values stored are the menu
settings that are currently based on the status of the Program Bus. Therefore, if you would like to
store a preset that has a 2.35 matte applied, you must first configure the Matte Aspect and Matte
Enable menu items, and then store the preset at one of the user preset addresses. When presets are
recalled, the settings are recalled to the Preview Bus and will not show on the Program Bus until the
TRANSITION button is pressed, or a GPI trigger invokes the transition.
The PRESET Setup menu is used to store and recall user presets as well as to configure the GPI and
GPO functions. Table 4-6 shows the items available in the PRESET Setup menu. Sections 4.11.1 to
4.11.6 provide detailed information about each of the sub-menus.
"
After upgrading the 7725DSK-LG with new firmware, all presets should be recalled
using the Recall Preset menu item, the values for new features must be set, and the
preset must be saved again using the Store Preset menu item.
IF THIS IS NOT DONE, OLD PRESETS COULD BE RECALLED WITH UNDESIRABLE
SETTINGS.

4.11.1. Configuring the GPI Inputs
The 7725DSK-LG is fitted with 8 general purpose inputs (GPIs) that can be configured to trigger 2
different actions - On Closure and On Open. For example, the On Closure event can be used to load
a preset and perform a transition to the Program Bus. The On Open event for the same GPI can be
used to load a different user preset and perform a transition to the Program Bus. For each event you
can configure a preset to load, transition to perform and logo to display.
GPI can also be configured using GPI script files, which are text-based files that can be programmed
and sent to your unit by Overture™. The syntax is important as the script represents programming code
that will be executed when the allocated GPI trigger event occurs. There are 8 GPI inputs. Each input
has 2 events: close and open. You can program scripts for each of these 16 events. If a script file is
present on the flash file system then the unit will process the script when the event is triggered. If the
script file is not present when a GPI event is triggered, then the internal GPI menu settings will be used.
