be recalled using the Recall Preset menu item, the values for new features must be

Configuring the GPI Inputs
The 7825DSK2-LG(-HD)(-3G) 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.
The GPI script files are text files therefore they can be easily edited in notepad. See appendix 10 for
more information on GPI scripting.
