GPI loading is a “single load” process triggered by a transition to ground: it needs to be activated only for a
short period (around 10 milliseconds) to be detected by the card. Since it is not activated by a level, it is not
necessary to maintain the level at ground after the activation.
GPIs, system and user presets are not operating modes: when loaded, they change only the current card
configuration.
