AIA Releases Camera Link HS Interface Standard Draft

POSTED 11/07/2011

rong>Camera Link HS will be demonstrated at VISION 2011

(Ann Arbor, Michigan, USA)  The Automated Imaging Association (AIA) has released the Camera Link HS draft standard (version 1.0). After a period of review by a committee of industry experts, the standard will be finalized and released to the public in 2012. Camera Link HS is a new high-speed camera communications protocol standard. The standard is hosted by AIA and is being developed as a global standard as outlined by the cooperation agreement on global machine vision standardization between the AIA, European Machine Vision Association (EMVA) and the Japan Industrial Imaging Association (JIIA).

Camera Link HS is the next generation advancement to AIA’s well-established Camera Link standard. It features high bandwidth (up to five times faster than Camera Link with up to 33.6 Gbit/s and future versions to 67.2 Gbit/s), data reliability (packet re-transmit which significantly reduces errors is available now in draft 1.0), low jitter, plug and play ease-of-use, built-in fault tolerance with CRC (cyclical redundancy check), cable lengths of up to 300 meters on fiber optic cable and 15 meters on copper cable with CX4 connectors. It is also GenICam compliant which will allow for an easy transition from Camera Link to Camera Link HS.

“With the release of Camera Link HS, the industry will have the best interface for demanding applications,” said Bob McCurrach, AIA’s Director of Standards Development. “Camera Link HS is truly a real-time connection, there are no latency issues. Because Camera Link is so well known and widely used, we’re sure to see Camera Link HS products multiply in the next year. Camera Link HS will increase the speed and throughput of vision systems, helping companies run faster with fewer errors,” added McCurrach.

Camera Link HS will be demonstrated in the International Standards Booth at the VISION 2011 trade show in Stuttgart, Germany, November 8-10. Silicon Software and PCO will demonstrate a camera and frame grabber with an image transfer rate up to 32 Gbit/s over fiber optic cable. Mikrotron and Silicon Software will demonstrate a camera and frame grabber with an image transfer rate up to 32 Gbit/s over CX4 cable. Teledyne DALSA will show a Camera Link HS Falcon2 area scan camera. 3M will display CX4 optical cables and SFP, plus flat twinax cables for Camera Link HS. Components Express, Inc. will display Camera Link HS CX4 copper cables.

“Teledyne DALSA looks forward to making use of this new standard in early 2012 with our new Falcon2 area scan cameras, Piranha4 line scan cameras, and Xcelera Camera Link HS frame grabber,” said Mark Butler, Teledyne DALSA Manager of Product Management. “These products will greatly benefit from the high bandwidth and compact cabling capabilities associated with Camera Link HS. In addition, the guaranteed data delivery feature ensures that our customers will have 100% reliable inspections, while the resend technology of Camera Link HS ensures smaller and lower power heads are possible over competing technologies,” added Butler.

Companies displaying Camera Link HS technology in their booths at VISION 2011 include: Components Express, Inc. (Hall 4, B33), Intercon 1 (Hall 6, B31), Matrox Imaging (Hall 4, C18), Miktrotron (Hall 6, D35) and Silicon Software (Hall 4, D72).

With the addition of Camera Link HS, the Camera Link family of standards offers a protocol for a wide variety of needs. AIA also just released Camera Link 2.0, an update to the existing Camera Link standard. This standard will remain active for those who need reliable real-time speeds up to 6.8 Gbit/s over 10 meter cable. Power Over Camera Link (PoCL) allows the camera to be powered by the frame grabber through the Camera Link cable, which saves space and money. PoCL-Lite offers a smaller form factor for low-cost solutions.
