SCOTTSDALE, AZ. – October 22, 2004 – VITA, the VMEbus International Trade Association, announced today the successful ANSI (American National Standards Institute) reaffirmation
ballots of ANSI/VITA 5.1, Raceway Interlink, ANSI/VITA 17, Front Panel Data Port (FPDP), and ANSI/VITA 23, VME64 Extensions for Physics and Other Applications.
ANSI/VITA 5.1, Raceway Interlink, specifies a VME P2 secondary bus that allows high speed switched data transfers in parallel with VMEbus operations. This standard provides a
specification of the data link protocol and physical interface of a high performance extension to the VMEbus standard. This extension consists of high bandwidth, low latency interconnects across a VMEbus computer chassis backplane using the P2 connector. Bi-directional
connectivity between boards in a VMEbus chassis is achieved through the use of a network of crossbar switches with point-to-point interconnects. ANSI/VITA 5.1 was originally approved as an ANSI standard in August, 1999.
ANSI/VITA 17, Front Panel Data Port, standardizes a high speed protocol for transferring parallel data between VME modules via their front panels. This extension to the VME standard consists of a multi-drop synchronous parallel non-addressable bus connection between multiple boards in a single chassis. The connection is made to a connector on the front panel of each board by means of an eighty conductor ribbon cable. ANSI/VITA 17 was originally approved in February 1999.
ANSI/VITA 23, VME64 Extensions for Physics and Other Applications, provides implementation rules, recommendations, and guidelines that enhance the use of the VMEbus standard as specified in ANSI/VITA 1-1994, VME and ANSI/VITA 1.1, VME64 Extensions. It was originally championed by VIPA, the VITA International Physics Association, a special users interest group within VITA, and subsequently approved as an ANSI standard in March 1999.
John Rynearson, VITA’s Technical Director, stated, “ANSI procedures require that all standards be reviewed every five years and be reaffirmed, revised, or withdrawn. Each of these reaffirmed standards was judged by the VITA Standards Organization’s membership to be technically correct, free from errors, and relevant to the technical needs of today’s embedded system designers.”
All of VITA’s ANSI recognized standards are available in PDF and are available at no charge to VITA’s members. Non VITA members may purchase standards at VITA on-line web store (www.vita.com/on-line.html).
About VITA
VITA, the VMEbus International Trade Association, is an incorporated, non-profit organization of vendors and users having a common market interest. Founded in 1984, VITA believes in and champions open system architectures as opposed to proprietary system architectures. VITA’s activities are international in scope. The functions performed by VITA are technical, promotional and user related and are aimed at increasing the total market size, providing vendors additional
market exposure and providing users with timely technical information. Today, VITA’s mission includes not only promoting VMEbus, but promoting the very concept of open technology as
embodied in the many standards currently under development within the VITA Standards Organization. Virtually all players in all markets from the smallest to the largest now use the
word “open” in their company and product promotions. The VITA name is now synonymous with open systems.
VITA’s continuing goal is to unite manufacturers and users through the acceptance and implementation of open technology standards. For information about VITA membership, or to find out how to obtain VITA specifications, visit the VITA website at www.vita.com or call
