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.
