With the DS4505 Interface Board, you can connect a dSPACE system to different bus systems via dedicated plug-on modules. The DS4505 is a carrier board that can carry up to four DS4340 (for connection to a FlexRay bus) and/or DS4342 modules (for connection to a CAN FD bus).
With the DS4505 Interface Board, a dSPACE system with modular hardware can be connected to a FlexRay and/or a CAN FD communication system. It is ideally suited for testing applications with a dSPACE prototyping system or dSPACE Simulator. The board can carry up to four interface modules.
There are two additional interface modules for the DS4505 Interface Board: the DS4340 FlexRay Interface Module for connection to FlexRay buses and the DS4342 CAN FD Interface Module for connection to CAN FD buses. The modular structure enables the use of both modules on one DS4505 simultaneously.
FlexRay is a time-triggered communication system for in-vehicle applications with demanding communication needs. It is the standard for deterministic, high-performance automotive communication networks. The basic principle of time-triggered systems is that tasks are executed and messages are sent according to a predefined schedule. In FlexRay, activities are aligned to a global time base, whereas in nondeterministic communication protocols such as CAN, they are mainly event-triggered at run time.
The CAN FD (FD = Flexible Data Rate) protocol was introduced to enhance the classic CAN protocol in terms of data rates and payload data length. With CAN FD, a multiplied data rate allows an average data transmission speed of several Mbit/s and payload lengths of up to 64 bytes (compared to 8 bytes in a classic CAN).
