 Flexible line-scan camera operation with the rate converter

 • 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.

 • to the same card

 • to different cards in the same PC

 • to different cards in different PCs

Including support for

 • GenApi

 • The Standard Feature Naming Convention (SFNC)

 • GenTL

 Windows, Linux and macOS drivers available

 • Including support for Intel 64-bit platforms as well as ARM 64-bit platforms

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.

 • Direct capture of image data to GPU memory is available using AMD’s DirectGMA. Compatible with

AMD FirePro W5x00 and 

above and all AMD FirePro S series products.

 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 

250VDC and 170VAC RMS.

 • Isolated contact outputs.

 • High-speed 5V-compliant TTL inputs/ LVTTL 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

Coaxlink’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 Coaxlink board generates a signal to control

an illumination device connected to one of its output lines.

Buffer metadata are only captured when the first image line of a buffer is acquired.

The metadata are composed with a configurable set of general purpose event counters, quadrature encoder

The metadata are composed with a configurable set of general purpose event counters, quadrature encoder position counters and/or I/O line status.

This feature allows line-scan applications to correlate image data with system events including motion encoder positions.

This provides designers with an amazing degree of freedom in the application development process.

Line Scan Trigger Capability 2/2

– The Coaxlink image acquisition card controls the camera scan rate based on signals received from the motion encoder.

If the part is moving faster, the camera’s acquisition line rate will increase.

If the part is moving slower, the camera’s acquisition line rate decreases.

– The Coaxlink board interprets the A/B signals from the Quadrature Motion Encoder to know in which direction (forward or backward) the part is moving.

– The Coaxlink card can also be commanded to acquire laser lines when the object is moving only forwards or only backwards.

– When a backward movement is detected, the function called ‘Backward movement cancellation’ stops the acquisition.

Line acquisition is automatically resumed when forward motion is resumed at the position where acquisition was interrupted.

– The rate converter enables the camera to acquire lines at any programmable resolution below or above the resolution of the motion encoder.

This provides designers with an amazing degree of freedom in the application development process.
