Dalsa Coreco : X64-AN QUAD
Description
The X64-AN Quad is a high-performance PCI-X bus compatible frame grabber. Driven by the need to integrate vision automation with multiple view
inspection, the X64-ANQuad is designed to deliver concurrent image acquisition from multiple independent standard and progressive scan analog cameras.
The X64-AN-Quad is capable of grabbing from four independent cameras at the same time, and offers independent control signals for each input channel
to acquire, transfer and track images accurately. Supporting high-resolution 8-bit image digitization, the X64-AN Quad offers independent image paths
creating virtually four frame grabbers in one slot. The X64-ANQuad has been engineered within DALSA’s exacting Trigger-to-Image Reliability technology
framework to more reliably and efficiently control and monitor the entire image acquisition sequence.
In addition to high precision 8-bit digitization and independent camera control signals, the Xcelera-AN also offers 4 independent image paths to the host, creating
virtually four frame grabbers in one PCIe x1 slot.
The X64-AN-Quad has been built within Teledyne DALSAs Trigger-to-Image Reliability technology framework. High-speed in-line machine vision
applications require tight integration between the trigger, strobe, camera exposure and frame grabber acquisition to ensure data integrity. Trigger-to-Image
Reliability leverages Teledyne DALSAs hardware and software innovations to control, monitor, and correct the image acquisition process from the time that an external
trigger event occurs to the moment the data is sent to the PCI bus, providing traceability when errors do occur and permitting recovery from them.
Successful machine vision applications require consistent and predictable results in demanding operating environments. With all image acquisition functions integrated
on a single board and under a single API, the X64-AN Quad ensures highly reliable acquisition control throughout the entire image capture sequence
from the time a trigger is fired to the time an image is available in host memory. Embedded timing logic within the boards Acquisition Control Unit (ACU) provides
timing signals to drive HD and VD for each input channel. A dedicated timer/counter for each module also ensures that the acquired images are tracked reliably
throughout the data path allowing image data to be readily correlated with physical objects on the production line. Capable of acquiring images at rates up to 50MB/s
per input path, the X64-ANQuad makes image acquisition from the new generation of analog cameras more efficient and supports operating modes such as
asynchronous reset, E-donpisha, partial scan, and WEN.
For improved image quality and accuracy, the X64-AN-Quad offers an optional fifth order Butterworth anti-aliasing filter to remove unwanted noise from
the video signal; separate gain and offset controls for each video input span the entire 0.4 to 1.2V range in steps of 780μV. These precise and flexible controls give
operators the ability to adapt input video signals to deliver digitized images that are highly linear and have low jitter noise.
The X64-AN Quad performs acquisitions from up to four independent format analog cameras with a comprehensive suite of independent control signals such
as master mode synchronization, WEN, frame reset, trigger, and strobe outputs. The X64-ANQuad comes bundled with CamExpertTM a proprietary camera
configuration utility specifically designed to leverage the power of Teledyne DALSAs image acquisition boards. This Windows-based utility provides an interactive
environment within which to create a new, or modify an existing, configuration file for both standard and progressive scan cameras.
The X64-AN-Quad features visual status LEDs to simplify system setup and diagnostics. A status indicator LED provides visual feedback once the camera
connection is made and properly synchronized. These visual indicators greatly facilitate the diagnostic process by allowing developers to instantly recognize if
cabling has been correctly set up.
Delivering fast and secure data transfer with zero CPU usage, the Data Transfer Engine (DTE) features a high-speed memory interface, multiple independent Direct Memory
Access (DMA), and onboard tap descriptors, the DTEs powerful architecture delivers robust performance for critical machine vision tasks. The DMAs allow the DTE to
transfer images from the ACU to local frame buffer memory, or transfer the same image to multiple addresses in the host memory. The ACU and DTE use the onboard 128MB
memory to perform these operations concurrently, yet at different rates, yielding optimal utilization of system bandwidth.Conventional PCI bus transfers, utilizing
scatter-gather techniques, rely on the CPU to load the host frame buffer destination memory addresses during live acquisition, which increases the load on the CPU and
slows image-processing tasks. The DTE offloads this task by automatically capturing and storing the destination frame buffer addresses from the host memory. In
addition, it performs autonomous and robust image transfers in non-real-time operating systems, such as Windows XP, Windows 2000.
An optional module offers opto-coupled inputs and outputs for demanding industrial environments. These interrupt-driven, general-purpose input and output controls
allow X64-AN Quad boards to react to external inputs more rapidly and predictably increasing the quality of acquired images.
To synchronize image captures with external events the X64-ANQuadd features an optically isolated trigger input and a strobe control signal for each
input channel. The signals can be programmed as active high or active low, edge or level based and can be controlled independently
The X64-AN-Quad features four independent onboard RS-232C ports that provide integrated support for camera control and setup for machine vision
applications. PC-independent in nature, these communication ports can easily be used with off-the-shelf communication utilities such as Windows-based HyperTerminal.
The X64-AN Quad is fully supported by Teledyne DALSAs Sapera Essential vision software. Sapera Essential is a suite of image acquisition and
processing libraries, tools and utilities. Sapera Essential offers a powerful camera configuration utility called CamExpert and image processing library evaluation
tool, Sapera Architect. In addition to more than 300 image processing functions, Sapera Essential offers a selection of image processing tools for machine vision
including pattern finding (area and edge based techniques), OCR, barcode, calibration and blob analysis. Fully supported by Teledyne DALSAs Trigger-to-Image
Reliability framework, applications based on the X64-ANQuad products deliver robust, reliable and cost effective solutions.In addition, Sapera
Essential applications can be developed using C/C , C#1 and Visual Basic using Microsoft® Visual Studio® 6.0 and higher on Windows XP or Vista 32-bit platforms.
