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.
