10. Accept the default Debounce Time. This input threshold setting in milliseconds is 200 by
default, which means the system will ignore any signal shorter than 200 milliseconds.
11. Click Apply.
12. Set First Input Pin. Options include 0-15, with the zero (0) representing the first pin and fifteen
(15) representing the sixteenth pin, which is the maximum. This numerical value is card
dependent.
13. Click Add Event. The Add New Event dialog box appears.
14. Select the type of event. Options include:
Trigger GPI input. Used for normal, GPI button type; push the GPI button for it to
trigger play, pause, cue, and so forth. The GPI signal occurs only while
the button is held down, usually no more than a fraction of a second.
Level GPI input. Extended on/off. While on, the voltage (usually around 5
volts) will remain high. This is useful for channel-specific actions like
play (active) and stop (inactive), and can also be used for tally tally
restriction/reflection. The signal will stay active as long as the switch
allows the voltage signal to continue.
