Grablink DualBase

• Support of the Windows Core Isolation security feature
• Windows 11 support
• Support of recent Linux distributions & kernels
• New Python bindings for MultiCam

• Compatible with a wide range of sensors and motion encoders.
• High-speed differential inputs: Quadrature motion encoder support up to 5 MHz.
• Isolated current-sense inputs: 5V, 12V, 24V signaling voltages accepted, up to 50 kHz, individual galvanic isolation up to 500VAC RMS.
• Isolated contact outputs.

Grablink supports continuous web scanning (to inspect infinite, continuously moving surfaces without losing a single line) and discrete object scanning (to acquire the image of objects moving in front of the camera).

• A trigger is used to start the acquisition when the part is in position. Hardware triggers come from the board's I/O lines. Software triggers come from the application.
• After it is started, the acquisition either:
  • Continues indefinitely (for web inspection applications)
  • Continues for a programmable number of lines (to acquire the image of objects of a known length)
  • Continues until an end trigger is received (to acquire the image of objects of a variable length)
• An optional trigger delay is available to postpone the beginning of the acquisition for a programmable number of lines.

• Use longer, up to 15 meters long, Camera Link cables!

• Direct transfer into user-allocated memory and hardware boards that expose PCI addresses
• Hardware scatter-gather support
• 64-bit addressing capability

• The Grablink frame grabber controls the camera scanning rate based on the signals received from a motion encoder. When the parts move faster, the acquisition line rate of the camera increases. When the parts move slower, the acquisition line rate of the camera decreases.
• The Grablink boards interpret A/B signals from quadrature motion encoders to know in which direction (forward or backward) the part is moving.
• Optionally, the Grablink can be instructed to acquire lines only when the object is moving forward or only when the object is moving backward.
• A feature called Backward Motion Cancellation stops the acquisition when a backward motion is detected. The line acquisition automatically resumes when the motion is again in the forward direction, at the exact place where the acquisition was interrupted.
• A Rate Converter allows the camera to acquire lines at any programmable resolution lower or higher than the resolution of the motion encoder. This gives the designer incredible freedom and flexibility during the development of the application.
• A Rate Divider allows the camera to acquire lines at a resolution lower than the resolution of the motion encoder. It divides the frequency of the incoming encoder signal by a programmable integer.

• A trigger is used to start the acquisition when the part is in position. Hardware triggers come from the Grablink's I/O lines. Software triggers come from the application.
• An optional trigger delay is available to postpone the acquisition for a programmable time.
• A trigger decimation function allows to skip some of the triggers.
• Camera exposure control allows the application to control the exposure time of the camera.
• When the acquisition starts, at the appropriate timing, the Grablink board generates a signal to control an illumination device connected to one of its output lines.

• The rate converter is a smart, programmable frequency multiplier/divider.
• Used with motion encoders and line-scan cameras, it allows the user to choose the aspect ratio of the pixels in the image.
• It provides a way to calibrate the acquisition chain to easily reach square (1:1 aspect ratio) pixels.
