| Setting | Description | 
|---|---|
| Direction | Configure the input signals coming into the device, or the output signals sent out. Select the GPIO port configuration: Input, Output, Static High, and Static Low.  Static High sources the current for an external load. Static Low sinks the current for an external load. | 
| Signal Type | Configure the Signal Type: Normal or Hardware Trigger. Normal Trigger - signal is routed through the device software. Normal Trigger is useful for Continuous, Level, periodic, Presentation, and Burst modes. Hardware Trigger - signal is routed through the device hardware directly to the sensor, bypassing the processing of the trigger. Hardware Trigger is more responsive and useful for Single Trigger use cases. | 
| Advanced Settings | Use Input to configure Input Debounce and Input Delay. Use Output to configure Pulse Width and Output Delay. | 
| External Illumination Mode | Toggle this setting to automatically configure the pins in this port to power and control external illumination. |
