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.
