Combo eases MOST testing

STUTTGART, Germany — The combination of Vector Informatik's CANoe.MOST 5.1 and VN2600 MOST interface provides a comprehensive MOST analysis and test too.

The VN2600 MOST interface can be used as a Node as well as a Spy to the MOST control channel and asynchronous channel. A typical reaction time of 5milliseconds data throughputs of 800messages/second can be achieved using the USB 2.0 port.

Added to CANoe.MOST version 5.1 are the dedicated windows displaying important network states and the allocation table. Also, it is now possible to listen to audio channels or run audio data onto them. A test feature set now facilitates the creation of sequential test scripts with the function catalog support.

The VN2600 MOST interface gives the user access to the control channel and asynchronous channel simultaneously, as a Node as well as a Spy. The user has the capability of monitoring audio channels via the headphone output or injecting audio data onto the MOST ring via a Line-In input.

The Control-Spy delivers messages online to the PC at a rate up to the maximum theoretical bandwidth of about 3,000 messages per second. At the same time this interface enables typical reaction times of 5 milliseconds. This allows the user to acquire all events on time and react as necessary, even during phases of high busload.

The VN2600 provides precise time stamps with a resolution of 1microsecond and precise synchronization of time stamps to those of other Vector interfaces. For example, in the context of tasks in a gateway environment users can set up precise sequences of MOST and CAN messages and define transfer times through the gateway.

The CANoe.MOST 5.1 analysis window displays the allocation table and the user can allocate or reallocate channels here. The user interface also makes it easy to select audio channels for monitoring by headphones, or for feeding audio data to the MOST interface via the line-in input.

A display of network states is available in a dedicated window, e.g. Light&Lock, configuration status and node addresses. In the trace window the user can now view messages at a glance in disassembled form, including transmitted parameters. Key events such as Light&Lock, messages with a set NAck bit, and important messages from the Network Master are highlighted in color.
