10. APPENDIX A
10.1. GPI SCRIPTING
GPI script files 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
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, which can be easily edited using notepad.
The title of a script is used by the system to determine which GPI event this file is applicable to.
i.e. gpi-h-close, gpi-a-open
In this case,
gpi
states that the script will be running off the state of a GPI trigger. The
h
represents
which specific GPI trigger the script will react to. GPI triggers range from A to H.
Close
shows that the
script will run when the GPI is in a closed state.
In the programming language the script utilizes, a comment is represented by the symbol
#
. Any text
that follows this symbol on a line of code will not execute a command or conduct any sort of action.
i.e. # this file describes the complete state of the keyer
CMD represents a command that is to be executed by the script when it runs.
i.e. cmd load_preset(1)
There are many different kinds of commands that can be run, and each command will perform a
specific action when the script is run.
•
cmd load_preset(1):
This command will load preset 1.
•
cmd udt_start(1):
This command will start up/down timer #1.

•
cmd media_toggle("05.evl"):

faded out it will be faded in, if it is faded in then it will be faded
out.
•
cmd udt_stop(2):
This command will stop up/down timer #2.
•
cmd udt_toggle(1):
This command will toggle the start/stop state of the up/down
