PRO I/O GPIO AND PRO I/O SW
Use the PRO I/O GPI and PRO I/O SW screens to assign General Purpose Inputs and Outputs (GPIO) on the
PRO I/O MODULE. You can map I/O actions to the GPIO and AUX connectors on the PRO I/O MODULE.
When mapping actions, High and Low refer to the voltage; High is the rising edge (transition from low voltage
to high voltage) and Low is the falling edge (transition from high voltage to low voltage). In practice, Low/High
correlates to the press/release of a trigger or the on/off position of a switch.
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 trig-
ger starts/stops recording.
GPIO CONNECTOR
This table describes the I/O options for the GPIO connector on the PRO I/O MODULE:
I/O OPTION DEFAULT ACTION PIN
GPI A High Key Disabled 2
GPI A Low Record: Toggle 2
AUX CONNECTOR
This table describes the I/O options for the AUX connector on the PRO I/O MODULE:
I/O OPTION DEFAULT ACTION PIN
GPI B High Key Disabled 6
GPI B Low Record: Toggle 6
SW 1 High Key Disabled 7
SW 1 Low Go to: Playback 7
SW 2 High Key Disabled 5
SW 2 Low Record: Toggle 5
