Ultra-fast digital Camera Link image acquisition board

Grablink Avenue is an ultra-fast PCI frame grabber for line-scan or area-scan digital Camera Link cameras. It is ideal for industrial applications such as high-speed moving objects, web inspection or high-resolution acquisition.

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 board acquires the 24-bit data, with any tapstructure, at the maximum speed of 85 MHz.

With line-scan cameras, Grablink Avenue guarantees a constant sensitivity of the image regardless of the web speed variation, thanks to ADR™, a unique patented downweb resampler.
Grablink Avenue is equipped with various I/O lines.

Features:

Support of one Camera Link camera in Base configuration
Up to 24 bits at 85 MHz
Full support of line-scan cameras
ADR™ (Advanced Downweb Resampling)
Line trigger and exposure contro
Full support of area-scan cameras
Asynchronous reset and exposure control
9 various external and internal I/O lines
Including 4 enhanced TTL I/O lines
32 Mbytes on-board memory
64-bit, 66 MHz PCI bus, 3V/5V signaling
Camera Link serial line using API functions or configurable as a PC COM port

Support of the Base Configuration:

Fitted with one Camera Link connector, Grablink Avenue supports the Base configuration of the Camera Link standard. Grablink Avenue supports various types of cameras.

Base configuration	1 tap x (8-10-12 bits)	2 taps x (8-10-12 bits)	-	1 tap x (24 bits)

Extended Base configuration - Multiplex	-	-	4 taps x (8-10-12 bits)	1 tap x (30-36 bits)

Various tap geometries are supported.

ADR™ - Advanced Downweb Resampling

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.

Serial Control of Cameras

Grablink series supports the Camera Link serial line. The application software uses the Camera Link API functions to control the camera. Alternatively Grablink offers the serial line configured as an additional PC COM port.

Nine various external and internal I/O lines

Grablink Avenue is fitted with a male HD26 external connector and a 26-pin internal header. All nine I/O connections are available both from the outside of the PC enclosure or directly from the PCB. System components such as trigger, strobe or motion encoder benefit from different types of interface:

One opto-isolated output for the safe control of external equipment
Two differential, including LVDS compatibility, input lines allowing a high-speed flexible control of the acquisition
Two isolated I/O lines and associated power supply compatible with the other Grablink boards
Four enhanced TTL I/O lines used, for instance, for interface with the user’s application
