Grablink Series: High-speed digital Camera Link image acquisition boards
The Grablink series is a range of high-speed PCI and cPCI frame grabbers for line-scan or area-scan digital Camera Link cameras. State-of-the-art cameras are easily connected with off-the-shelf Camera Link compliant cables. The Grablink series is ideal for industrial applications such as inspection of high-speed moving objects, web inspection or high-resolution acquisition.

The Grablink Value is a cost-effective board acquiring images from one camera in the Camera Link Base configuration. The Grablink Avenue is a high-performance 64-bit, 66 MHz PCI bus board acquiring images from one camera in the Camera Link Base configuration. This new board includes a patented feature, ADR Technology™, allowing to facilitate line-scan acquisitions. The Grablink Expert 2 is a high-performance 64-bit, 66 MHz PCI bus board acquiring images in two Base configurations or one Medium configuration. The Grablink Value and the Grablink Expert 2 are available in a Compact PCI version.

The New Grablink Quickpack CFA and the Grablink Quickpack ColorScan provide the most appropriate image acquisition and a set of hardware accelerated pre-processing functions. This line of products offers, in quite a way, the right solution to a dedicated application.

All Euresys frame grabbers offer an unprecedented control over the memory allocation process thanks to scatter-gather DMA transfers into user allocated memory. The Euresys boards come with the MultiCam driver available under Windows and Linux.

Serial control of camera
The Grablink series supports the Camera Link pseudo RS-232 serial line. The application software can use the Camera Link API functions to control the camera. Alternatively, the serial line can be configured as an additional PC COM port ensuring interoperability with existing camera control software.


Bus mastering
All Euresys frame grabbers are PCI bus mastering agents that directly store the acquired images into the PC physical memory without CPU involvement. As a unique feature, a Euresys board automatically recovers the scatter-gather virtual memory mapping to present the data as a regular bitmap image in a user allocated memory buffer.


Interfaced cameras
The Grablink series interfaces many different cameras.
An up-to-date list is available on the Interfacing Cameras page.

GrabLink Series, Frame Grabbers for line scan and area scan applications

Line-scan applications

Camera modes: the Grablink series interfaces to state-of-the-art Camera Link line-scan cameras with line rate and exposure control. Free running cameras are supported as well.

Continuous web scanning: the "web mode" allows inspecting a continuously moving surface without losing a single line.

Successive object scanning: in "page mode", the Grablink acquires a set of consecutive lines constituting a 2D image. The acquisition starts when the object enters the camera field of view, as signaled by an external trigger.

Motion Encoder: when the observed web or object moves at a variable speed, the frame grabber imposes a camera scanning rate derived from a motion encoder. This guarantees a fixed pixel aspect ratio. Perfect square pixels are achievable. A built-in rate converter of the Grablink boards defines any ratio between the camera scanning rate and the encoder pulse rate with 1/1000 resolution. Thus, an off-the-shelf encoder can serve several applications. The exposure control feature guarantees a constant sensitivity despite the speed variation.

ADR TechnologyADR Technology*: In many applications, a line-scan camera has to be operated at a constant cycling rate in order to maintain a constant sensitivity. Grablink Avenue implements ADR*, a unique downweb resampling feature, yielding a defined aspect ratio irrespective of web speed variations, even without an electronic shutter on the camera.

A built-in rate converter accommodates an off-the-shelf motion encoder to control the line acquisition process, enabling any programmable aspect ratio, including perfect square pixels. ADR* makes the most of the line-scan camera, as the sensitivity is not impaired by the shuttering.


See our Grablink Quickpack ColorScan for RGB line-scan inspection.


Area-scan applications


Camera modes: features such as asynchronous reset, exposure control, strobe lighting often required in industrial applications are available on Grablink series. The synchronous mode is also supported.


Trigger and exposure control: an external signal can be sent to the frame grabber to trigger the acquisition. Grablink series is capable of consistently controlling the exposure time and the illumination.


Camera tap structure: any tap structure, Grablink delivers a re-ordered bitmap image to the PC memory. Tap-reversal is supported. With the multiplex tap technique, several taps are interleaved over Camera Link as long as the combined data rate remains below the pixel clock frequency specified for the board.


See our New Grablink Quickpack CFA for color area-scan inspection.
