GPI Inputs Tab
This sets up the task to execute on each GPI input when activated. Some tasks are level
sensitive (0 volts in = off, 5 volts in = on), whereas others are transition sensitive (a
transition from 0 to 5 volts will toggle the current state). An example of a level sensitive
task is the Hardware Tally: 0 volts will switch the tally off, 5 volts in will switch the tally on.
An example of a transition sensitive task is the Full Screen Toggle: if the relevant window
is currently at its normal size then a transition from 0 volts to 5 volts will switch it to full
screen; if it is at its full screen size then the transition will switch it back to its normal size.
Edge sensitive tasks can be identified as the ones that have "toggle" in their name.
