Generic Serial Interface DCI-GSI2

Function bypassing, measurement, ECU calibration and flash programming

The generic serial interface DCI-GSI2 can be used for function bypassing, measurement, ECU calibration, and flash programming. The broad range of available connector adapters lets you connect the DCI-GSI2 to individual electronic control units. 

  • Very low communication latencies for bypassing and high data throughput for measurement
  • Support of standardized XCP on Ethernet interface
  • Connection to a wide range of ECU types through target-specific connector adapters

Application Areas

With the continuing technological advances of ECUs, broadband access to ECUs is becoming a crucial feature. It can be used for tasks such as monitoring internal ECU variables or integrating bypass functions. Debug interfaces readily provide this kind of access without significant influence on the ECU microcontroller.   

For this purpose, dSPACE provides the generic serial interface DCI-GSI2, which can be used for function bypassing, measurement, ECU calibration, and flash programming. You can connect the DCI-GSI2 to individual types of ECUs using a wide range of available connector adapters.

Key Benefits

The DCI-GSI2 features bypassing without requiring any ECU source or binary code changes. It is synchronized with the ECU application and enables very high measurement data throughputs as well as extremely fast measurement rasters  (up to 100 kHz) via Gbit Ethernet. Because XCP on Ethernet is an open and standardized interface, it is also possible to connect XCP-aware third-party tools to the DCI-GSI2.

Connectors
  • Connector to on-chip debug bus:
    • Various connector adapters are available from dSPACE. Particular adapters also have a tool connector for connecting an additional tool, such as a debugger.
  • Ethernet connector:
    • 8 pin LEMO connector for connection to the host PC and/or the bypass system
  • Power connectors (only one power connector can be used at one time):
    • External 2 pin LEMO power connector on the enclosure for connection to an external power supply
    • Internal power connector for connection to the vehicle battery via the ECU. An internal power supply cable is provided.
Physical characteristics Enclosure
  • Aluminum box (to be ordered separately)
  Size
  • DCI-GSI2 with enclosure (DCI_GSI2_ENC1): 102.5 x 71 x 26.5 mm (4.04 x 2.8 x 1.04 in)
  • DCI-GSI2 without enclosure: 70.05 x 62.4 x 10.5 mm (2.76 x 2.46 x 0.41 in)
  Weight (without connector adapter)
  • DCI-GSI2 without enclosure and without connector adapter: approx. 28 g (0.06 lb)
  • Connector adapter (depending on type): approx. 20 g (0.04 lb)
  • Enclosure (DCI_GSI2_ENC1): approx. 190 g (0.42 lb)
  Temperature range
