DS4302 CAN Interface Board1)

Interface to CAN bus

With the DS4302 CAN Interface board, you can connect a dSPACE system to the controller area network (CAN). The board provides four independent CAN channels, each with a CAN controller and three different CAN transceivers.  

Application Areas

The DS4302 CAN Interface Board has been designed to operate in controller area network (CAN) environments, which are used primarily in the automotive and automation industries. Typical application fields of the DS4302 are:

  • In-vehicle rapid control prototyping
  • Hardware-in-the-loop (HIL) tests
  • Restbus simulation
  • Automation tasks 

Key Benefits

The DS4302 enables dSPACE PHS systems to take part in CAN-bus traffic without the need for extra interface electronics. Its three individual transceivers on each of the four independent channels cover several CAN application areas. They include a high-speed transceiver for hard real-time communication and a fault-tolerant low-speed transceiver, necessary for tasks such as comfort electronics. Every configuration of the DS4302 can be carried out in a Simulink® block diagram, thereby eliminating CAN controller programming. 

Comprehensive Software Support

With the RTI CAN Blockset, you can easily configure all CAN interfaces in Simulink by using a dialog-based method, without any complicated CAN controller programming. The configuration options range from message setup to interrupt configuration, right through to message time-stamping. The easiest way is if you already have communication description files: simply import them, and your CAN hardware is configured. For efficient and dynamic handling of complex CAN setups in HIL applications, we offer the RTI CAN MultiMessage Blockset, which lets you manage large CAN message bundles (> 200 messages) from one Simulink block.

1)The end of life of the dSPACE PHS (peripheral high-speed) hardware for modular systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. After the end of life, no services of any kind will be available for these products. We advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.
