MOST

MOST 1 (Media Oriented System Transport) is a serial communication system for transmitting audio, video and control data via fiber-optic cables. This multifunctional, high-performance multimedia network technology based on synchronous data communication requires professional software tools and hardware interfaces.

Software Tools for MOST:

CANoe/DENoe and CANalyzer/DENalyzer

MOST engineering requires powerful development, analysis and test tools. CANoe.MOST respective DENoe.MOST as well as CANalyzer.MOST and DENalyzer.MOST are the ideal solutions.

Application Areas:

• Analysis of a MOST ring
• Complete simulation of up to four MOST devices
• ECU functional and integration test
• Network integration
• Gateway simulation and test

DENoe.MOST and DENalyzer.MOST

New Features:

Both CANalyzer/DENalyzer and CANoe/DENoe now support the new Vector MOST Interface VN2600. Due to its USB 2.0 port the VN2600 provides a high data throughput (e.g. simultaneous Node and Spy mode) as well as low response times (<5 ms). It supports simultaneous operation of Control Node and Control Spy modes and provides access to asynchronous channels.

• Important hardware and network states are displayed clearly in a separate window during the measurement, e.g. Light&Lock, node addresses and operating modes.
• Allocation Table assignments are also shown in a separate window. This window allows channels to be allocated or released, and the user can select an audio channel for listening or to feed in audio data.
• The Trace window features event highlighting of important MOST events, for example Light&Lock, Configuration Status or messages where the NAck Flag is set. Additionally, the parameters will be shown in a symbolic way in the disassembly column. The AMS combiner supports now the offline mode and the import of logging files into the Trace window.

Additionally, with the .MOST option for CANoe/DENoe 5.1 sequential test scripts can be defined with support of the Function Catalog with the syntax used in the MOST specification.

MOST Hardware

VN2600 – USB Interface for MOST ®

The VN2600 offers a very fast and reliable hardware interface for accessing MOST networks.

Features and Advantages:

The MOST interface VN2600 with a USB 2.0 port provides a high throughput (e.g. simultaneous Node and Spy mode) as well as low response times of typically < 5 ms. The easy synchronization of the VN2600 with Vector's CAN and LIN interfaces in combination with CANoe and CANalyzer (version 5.1 or higher) guarantees an effective development and analysis of all automotive bus systems. With the XL-Driver-Library, specialized tools can be created which maximize productivity by meeting exactly the requirements of the dedicated workplace and its environment. The MOST Interface is extremely reliable and robust, which is proved especially when transferring large amounts of data.
