PRO I/O GPIO AND PRO I/O SW
Use the PRO I/O GPI and PRO I/O SW menus to map input and output (I/O) actions to the GPIO and AUX 
connectors on the Pro I/O Module.
Low and High refer to the voltage. In practice, Low/High correlate to the press/release of a trigger or the on/
off position of a switch.
  Low: The falling edge (transition from high voltage to low voltage).
  High: The rising edge (transition from low voltage to high voltage). 
For example, if you connect a start/stop trigger to the GPIO connector on the Pro I/O Module and keep the 
default GPIO A High and Low settings (Key Disabled and Record: Toggle, respectively), then pressing the 
trigger starts/stops recording.
