MVS-8500 Series
High-Speed Analog PCIe and PCI Frame Grabbers The Cognex® MVS-8500™ Series of machine vision frame grabbers supports the latest high-speed analog camera technology. Two new additions to the Series support PCI-Express bus architecture and quad-speed analog cameras. With a system cost close to that of direct connect cameras, and the bandwidth, reliability, and integrated I/O of a full-featured frame grabber, the MVS-8500 Series is in a price-to-performance class all its own. In addition, these half-slot frame grabbers are backwardcompatible with legacy analog cameras, while supporting new busses and operating systems – making them the perfect choice for bringing existing applications forward to the future.
Fast Image Transfer in Parallel with Acquisition Unlike direct connect camera technologies, MVS-8500 frame grabbers free up the PC host processor for image analysis by providing high-speed image transfer directly to system memory. They maximize acquisition speed and efficiency with pipelined processing and on-board image buffering, which allows new images to be acquired while the previous image is being transferred. The MVS-8500e models support up to four independent high-speed analog cameras, in a variety of formats.
No Need for External I/O By incorporating on-board triggers, strobes and general-purpose TTL I/O, the MVS-8500 Series eliminates the need for additional I/O hardware in the PC. All input lines generate interrupts based on programmable rising or falling edges and variable pulse widths, providing compatibility with a wide variety of third-party sensors. These features provide uses with a closed-loop system that ensures complete reliability and control from trigger to image transfer.
Camera Support Extensible architecture allows the MVS-8500 to maintain support for existing cameras while easily adding new ones. From legacy cameras to the latest high-speed, color, and large-format analog technology, the 8500 Series meets all application requirements.
Software Development Environments As with all Cognex frame grabbers, the MVS-8500 Series supports Cognex high-performance machine vision software to meet the speed, accuracy and reliability requirements of the most demanding applications. VisionPro® Machine Vision Software is a suite of Cognex software tools for the Microsoft ® Visual Studio ®.NET programming environment. VisionPro combines the power and flexibility of advanced programming with the ease of development of a graphical prototyping environment. This enables OEMs, system integrators and automation engineers to quickly develop and deploy custom machine vision applications.
Advantages • Flexible design supports legacy cameras as well as the latest quad-speed, color, and large format analog cameras • Allows fast and reliable image transfer through PCI-Express bus architecture • Provides the most reliable, accurate, and repeatable results through tightly-integrated Cognex software tools
MVS-8500 Series Specifications MVS-8504e – With four completely independent A/D converters and support for quad-speed cameras, the MVS-8504e PCI-Express frame grabber is built for maximum speed. It manages asynchronous or simultaneous acquisitions from up to four quad-speed analog cameras. The MVS-8504e features 16 configurable I/O points and supports any mix of high-speed, high-resolution, progressive-scan, and rapid-reset cameras. MVS-8500Le – The 8500Le features two acquisition channels multiplexed to a single A/D converter. With eight configurable I/O points and support for quad-speed cameras, this PCI-Express frame grabber is ideal for pricesensitive yet demanding applications. MVS-8504 – The MVS-8504 features four completely independent acquisition channels, 16 configurable I/O points, and PCI bus architecture. This frame grabber can manage asynchronous or simultaneous acquisitions from up to four double-speed analog cameras. MVS-8501 – The MVS-8501 incorporates four channels multiplexed to one A/D converter, and acquires from one channel at a time. This PCI bus frame grabber features 16 configurable I/O points and support single or doublespeed cameras.
