Acquisition: 24-bit/48-bit at a maximum of 66MHz

16Mbytes on board memory

Asynchronous reset, exposure control and

I/O lines (trigger & strobe)

Features

Software Support

The MultiCam driver enables control of several Domino and GrabLink

frame grabbers simultaneously, using an arbitrary number of cameras.

MultiCam allows defined channel linking cameras to be buffered into

the PC memory. The MultiCam channel identifies all parameters ruling

the acquisition process for a camera. All camera features, such as

resolution and control means, are reported through simple parameters.

The MultiCam driver runs under Windows 98SE/ME/NT/2000/XP.

GrabLink Expert 2 Image acquisition from digital Camera Link camera

Ordering Information

General

The EureCard GrabLink Expert 2 is a high-performance 64-bit, 66MHz

PCI bus board capable of acquiring images in 2-Base or one Medium

configuration. The GrabLink Expert 2 is a high-speed PCI frame grabbers

for line- or area-scan Digital Camera Links.

State-of-the-art cameras are easily connected with off-the-shelf Camera

Link compliant cables. The GrabLink Expert 2 is ideal for industrial

applications such as inspection of high-speed moving objects, web

inspection or high-resolution acquisition.

Configuration Supports

GrabLink Expert 2 is a Camera Link compatible frame grabber fitted

with two Camera Link connectors. It's capable of acquiring images

simultaneously or independently from two line-scan or area-scan digital

cameras in a dual Base configuration. GrabLink Expert 2 also supports

one camera in a Medium configuration. It supports various types of

cameras:

Line-scan Systems

Camera Modes: The EureCard 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 inspection of a

continuously moving surface without losing any lines.

Successive Object Scanning: In "page mode", GrabLink acquires a

set of consecutive lines constituting a 2D image. The acquisition starts

when the object enters the cameras 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 can

define any ratio between the camera scanning rate and the encoder

pulse rate with a 1/1000 resolution. Thus, an off-the-shelf encoder can

be used to serve several applications. The exposure control feature

guarantees a constant sensitivity despite the speed variation.

Serial Control of Cameras

The GrabLink Expert 2 supports two Camera Link pseudo RS-232

serial lines. The application software can use the Camera Links API

functions to control the camera. Alternatively, the serial lines can be

configured as additional PC COM ports ensuring interoperability with

existing camera control software.

I/O Board

GrabLink Expert 2 is delivered with an auxiliary I/O board implementing

the trigger and strobe facilities. The bracket is fitted with two connectors.

On the female DB9 connector, system components (such as a motion

encoder) benefit from isolated I/O lines and power supply. TTL trigger

and strobe lines are available on the female DB25 together with 16

fully programmable general-purpose I/O lines.
