The GPIO tab allows the user to control external devices connected to the camera, such as triggers or strobes.
The image below shows the functions provided in a trigger window.
Use the drop down menu to select the trigger type: Hardware, Software, or None to disable trigger.
With type set to Software, click "Trigger" to generate a software trigger.
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.
The image below shows the functions provided in the GPIO window.
Represents the type of signal being generated. For more information on available modes, see: General Purpose Input Output
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.
Up to three additional parameter fields may appear dependant upon what "GPO Mode" is selected.
Once the GPO mode is set, the description of the selected mode appears in the Description box.
After making any changes to the GPIO parameters, click Update to send these parameters to the camera.
