pixels in the image.

 • It provides a way to calibrate the acquisition chain to easily reach square (1:1 aspect ratio) pixels.

Line-scan triggering capabilities 2/2

 • The Coaxlink 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 Coaxlink boards interpret A/B signals from quadrature motion encoders to know in which direction

(forward or backward) the part is moving.

 • Optionally, the Coaxlink board 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.

 Line-scan triggering capabilities 1/2

 Coaxlink 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.

Direct GPU transfer

 • Sample programs for AMD DirectGMA and NVIDIA (CUDA) available.

 • Direct GPU transfer eliminates unnecessary system memory copies, lowers CPU overhead, and reduces

latency, resulting in 

significant performance improvements in data transfer times for applications.

AMD FirePro W5x00 and 

above and all AMD FirePro S series products.
