Davidsonville, MD -- AVT, Inc., designer and manufacturer of vehicle
network interface equipment, announces the new AVT-512 M-Module Network
Interface. The new model 512 is an M-Module unit that supports all
the current popular automotive networks in a single unit.
The following automotive protocols are supported by the AVT-512:
“We designed the AVT-512 to meet the high performance needs of VXI based systems that require an interface to the various automotive networks now on the road” said AVT senior engineer Michael Riley. “The M-Module form factor permits the installation of multiple modules into a single VXI chassis slot. The AVT-512 is a double wide M-Module that packs a lot of capabilities into one very small unit. For example, two AVT-512 units can be installed on one Agilent E2251A ‘C’ sized carrier board and still leave two M-Module locations available for other uses.”CAN, 2-wire CAN, GM Single Wire CAN (SWC) J1850 VPW (GM Class 2 compliant) J1850 PWM (Ford SCP compliant) Keyword Protocol 2000 (ISO 14230) [compatible with ISO 9141-2] Ford UBP (UART Based Protocol)
Mr. Riley went on to say that Agilent Technologies has shown an interest in the new AVT-512. In a recent conversation, Mr. Bob Patera, Agilent Technologies DAC Business Manager stated: “Agilent Technologies plans to use this new VXI based Vehicle Network Interface with our other VXI measurement products and channel partner software to provide more complete Data Acquisition solutions to the Auto Industry.”
The AVT-512 M-Module Interface is easy to use and rugged. Simple software commands control nearly every aspect of operation, including switching between modes of operation. A new Revision “B” unit is under development that will provide electrical isolation between the VXI host system and the external network for protection from faults and surges.
Host communications with the AVT-512 is done by direct register I/O. VXI Plug&Play drivers are under development.
The AVT-512 M-Module Network Interface is supplied with an installation hardware accessory kit and all documentation on disk.
As the content of electronics and the number of microprocessors and
microcontrollers in motor vehicles increases, the number and type of in-vehicle
networks is also increasing. These networks permit the sharing of
information between modules, sub-systems, and systems within the vehicle.
Multiple networks are used to segment the various sub-systems by:
type of information, data rate, reliability, safety, and other factors.
Over the past 20 years a large number of in-vehicle networks have been
developed or proposed by various organizations and companies. They
range from full proprietary, through pseudo open, to full open standards;
nearly all are different and incompatible.
