General purpose I/O lines

• 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.

High-performance DMA (Direct Memory Access)

• Direct transfer into user-allocated memory and hardware boards that expose PCI addresses

• Hardware scatter-gather support

• 64-bit addressing capability

Area-scan triggering capabilities

• 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.

Line-scan triggering capabilities 1/2

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.

Line-scan triggering capabilities 2/2

• 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.
