The HSLink interface is a new machine vision connectivity interface pioneered by Teledyne DALSA with the support of a number of other industry vendors. As a group we are working with the Camera Link 2 subcommittee to bring reference designs and a more complete specification to the table for industry use as the next generation Machine Vision interface.
HSLink is designed specifically to meet the needs of all machine vision applications and therefore carries image data, configuration data and low jitter, real time triggering signals over a simple network topology supporting cameras, intermediate devices and frame grabbers. The interface has taken the key strengths of Camera Link, and added new features and functions to meet the customer demands of today and tomorrow. HSLink is designed from a system point of view, ensuring the ability to create low cost cameras and frame grabbers, while meeting the ease of use, flexibility and data reliability demanded by end customers.
The HSLink IP Core takes in Camera Link signals and priority manages trigger, image data and configuration data and sends this information to the PHY via GMII (Gigabit Media Independent Interface) and/or NBI (Nine Bit Interface) in order to ensure guaranteed data delivery and it further simplifies design implementation in both framegrabbers and cameras. Multi-vendor PHYs, that operate on NBI and GMII, are available that serialize and de-serialize the data transmitted over the cable medium. For low bandwidth applications (<300Mbytes/s), Infiniband (IBx1) or Coax cabling offers a low cost solution. For applications up to 2100Mbytes/s, a single CX4 cable is used, which significantly reduces the size and number of cables required with today’s machine vision standards, and still delivers 15m transmission distances.
HSLink forms the basis for the Automated Imaging Association's new Camera Link HS standard. The standard, to be officially released in 2011, has widespread industry support from camera, frame grabber, and cable manufacturers.
