DS4201-S Serial Interface Board1)

Serial communication

The DS4201-S is an interface for serial communication between a dSPACE system and external devices. The DS4201-S provides communication on four separate channels.

The end of life for this product has been set. Please see the footnote for more detailed information.

  • Supports RS232, RS422, and RS485 line transceivers
  • Useful for connecting two systems over long distances

Application Areas

The DS4201-S Serial Interface Board can be used to set up communication connections between the dSPACE modular system and any external device via the RS232, RS422, or RS485 interface. You can connect external devices such as sensors, measuring instruments, or displays.

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.
