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
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

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.
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
The Grablink series interfaces many different cameras.

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
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
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.
