The GPIO tab allows the user to control external devices connected to the camera, such as triggers or strobes.




Trigger


The image below shows the functions provided in a trigger window.


Type


Use the drop down menu to select the trigger type: Hardware, Software, or None to disable trigger. 


Software


With type set to Software, click "Trigger" to generate a software trigger.


Hardware


Select Mode, Polarity, Delay and Number (if applicable) using the boxes and drop down menus. 


The availability of trigger modes is camera dependant. For more information on trigger modes, see: Trigger


After making any changes to the trigger parameters, click Update to send these parameters to the camera.


GPIO


The image below shows the functions provided in the GPIO window. 



GPO Mode


Represents the type of signal being generated.  For more information on available modes, see: General Purpose Input Output


GPO Polarity


Represents the polarity of the GPO signal (the rising or falling edge of the voltage signal). Select "Positive or "Negative"


Note: "Positive" has a different meaning for enclosed cameras, which has optocouplers and board-level cameras, which have TTL inputs.  See Triggers and GPOs for a detailed description.


GPO Parms


Up to three additional parameter fields may appear dependant upon what "GPO Mode" is selected.


GPO Description


Once the GPO mode is set, the description of the selected mode appears in the Description box.


Update


After making any changes to the GPIO parameters, click Update to send these parameters to the camera.
