The GPI port of
ISOSTEM
®
features an easy way to recall six parameter
presets remotely. A preset is triggered by pulling the dedicated preset pin to
the device´s electrical ground (GND). The GPI inputs are level-sensed.
Thus, a momentary push-button has to be pressed (to close its contacts)
for a very brief period of time (<1sec.).
The preset is called during state transition from open to closed, i.e. GND.
Thus, a momentary push-button switch is capable of calling a preset.
