The Japan Industrial Imaging Association (JIIA; Tokyo, Japan), host of the CoaXPress high-speed digital interface standard for imaging applications, has announced that the first edition of the standard has been "overwhelmingly approved" by its Working Group as a JIIA standard for public release.

The AIA/EMVA CoaXPress Liaison Group, which consists of members from the AIA (Automated Imaging Association, USA) and the EMVA (European Machine Vision Association), have also given their approval, paving the way for global adoption in early 2011. Representatives from both groups voted on the standard during the past month and the results were released in December 2010, showing a total of 31 votes in favor, none opposed and 2 abstentions.

JIIA also announced the launch of a compliance test procedure to test and approve CoaXPress devices as officially compliant products. This compliance program will also manage permission to use the CoaXPress name and logo. Additional details of how this process will work will be announced in 1Q11.

Following this ratification of the standard, reference JIIA NIF-001-2010 - CoaXPress Standard - Enacted on Dec. 6, 2010 - First Edition, the CoaXPress specification will now go through a three-month international appeal process, during which interested parties can comment on a wide range of technical and legal areas. The result of this process, which has been agreed upon by JIIA and the two other major industry organizations -- the AIA and the EMVA, will be announced at Automate 2011 in Chicago, USA and will pave the way for CoaXPress to become an international standard.

“We are well on our way to making CoaXPress a global and widely adopted standard for high-speed digital image data transmission,” said Tadashi Miyazaki, chair of JIIA CoaXPress Workgroup. “The voting results demonstrate the universal approval for the technical validity of the approach, as well as the support for a next-generation method for enabling flexible, high-speed connectivity between the components of imaging systems, including multiple cameras, frame grabbers, and image processing systems.”

“I’d like to thank and congratulate the many people and organizations that contributed to helping us reach this milestone for CoaXPress. I am pleased with the broad ranging support and input the specification has received, which confirms the industry demand for a solution of this type. We are also pleased to see the start of the product compliance process so the benefits of CoaXPress can quickly get into system developers hands,” said Jochem Herrmann, chairman of the CoaXPress Consortium.

CoaXPress was originally developed by Adimec, Active Silicon, and Components Express using chip technology from EqcoLogic. First products were demonstrated in Stuttgart, Germany at VISION 2009 (Nov. 3-5, 2009). These included cameras from Adimec, frame grabbers from Active Silicon and cables from Components Express. The products and technology were well received and the
CoaXPress Consortium won the Vision Award 2009 for innovative new technology. These products used an early version of the CoaXPress protocol referred to as "CoaXPress-TD."

CoaXPress is a digital interface specification that allows the transmission of high speed data from a device, for example a camera, to a host such as a frame grabber in a PC, at a high speed of up to 6.25Gbps over a single coax cable. CoaXPress works over relatively long cable lengths, depending on the precise cable type -- up to 40m at 6.25Gbps and further at lower speeds.

The interest from markets outside machine vision led to the formation of an “Adopters Group” whereby organizations for which machine vision is not a significant part of their business may gain access to the CoaXPress specification.
