DS4201-S Serial Interface Board

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.

  • 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.
