Use the Trigger dropdown menu to adjust trigger input settings.
Trigger Dropdown Menu
- None: Continuous operation; no trigger defined.
- Digital: Select from available digital inputs on the camera.
- Virtual: Select virtual triggers 1 through 2048.
- Sensor: The sensor input of the camera will trigger.
- Serial Trigger: A programmable serial command can be sent over a programmable port. The text field to the right of the Trigger dropdown menu accepts the following special non-printable characters:
\a bell
\b backspace
\f form feed
\n new line
\r carriage return
\t horizontal tab
\v vertical tab
\’ single quote
\x022 double quote ( ” )
\? question mark
\ooo three digit octal notation ASCII value, i.e. \145 = 'e'
\x0hh hexadecimal notation ASCII value, i.e. \0x04C = 'L'
When a trigger is selected and Wait for Triggers During Acquire and Tryout is selected, the Force Trigger button will appear above the Navigator Bar. This allows you to trigger the camera to acquire images and advance the Tryout Loop.
Precautions for Correct Use: Triggering from AutoVISION is intended for testing only and results in significant processing time variation. Use the actual trigger source for actual timing values.
Trigger Polarity allows you to set whether the trigger is Low > High or High > Low.
Allows the user to set a delay in milliseconds between the time when the camera receives the physical trigger, and when the camera will actually acquire the image. This is useful on production lines where the trigger can’t be physically aligned with the part. Increasing this value will allow the part to travel further down the production line before the picture is taken. Decreasing this value will acquire the image closer to actual trigger position.
Precautions for Correct Use: Trigger Delay only works for physical triggers. It does not work with Serial or Virtual triggers. For the HAWK MV-4000, Trigger Delay only works in Standard Acquisition Mode and not FPGA Assist Mode. This setting is accessed from Camera Advanced Settings.
