通用串行接口 DCI-GSI2

功能旁路、测量、ECU 标定和 flash 编程

通用串行接口 DCI-GSI2 可用于功能旁路、测量、ECU 标定和 flash 编程。具有各种接头适配器让您可将 DCI-GSI2 连接到各个电控单元。

应用领域

随着 ECU 技术不断发展,宽带接入 ECU 这一功能愈发引人注目。使用该功能可以执行 ECU 内部变量读取或旁路功能集成等任务。通过调试接口恰好可以实现这种接入方式,而且不会对 ECU 微控制器造成显著影响。

因此,dSPACE 推出了通用串行接口 DCI-GSI2,该接口可用于功能旁路、测量、ECU 标定和 flash 编程。各种可用接头适配器让您可将 DCI-GSI2 连接到各个电控单元。

主要优点

DCI-GSI2 在以太网接口上提供了一个开放式标准 XCP,用于连接第三方工具。另外,DCI‑GSI2 无需更改任何 ECU 源代码或十六进制代码便能设置旁路。它与 ECU 应用高度同步,可以实现极高的测量数据吞吐量和极快的测量栅格

Parameter Specification
Host Interface

  • For further interfaces, please contact dSPACE.
Connectors
  • Connector to on-chip debug bus:
    • Various connector adapters are available from dSPACE. Some adapters also have a tool connector for connecting an additional tool such as a debugger.
  • Ethernet connector:
    • 8 pin connector for connection to the host PC and/or the bypass system
  • Power connectors (only one power connector can be used at the same time):
    • 2 pin LEMO power connector on the DCI-GSI2 enclosure for connection to an external power supply
    • Internal power connector in the DCI-GSI2 for connection to the vehicle power supply in the ECU via the internal power supply cable
Physical characteristics Enclosure
  • Aluminum box (to be ordered separately)
Size
  • DCI-GSI2 with aluminum box: 102.5 x 71 x 26.5 mm (4.04 x 2.8 x 1.04 in)
  • DCI-GSI2 without aluminum box: 70.05 x 62.4 x 10.5 mm (2.76 x 2.46 x 0.41 in)
Weight (without connector adapter)
  • DCI-GSI2 with aluminum box: approx. 220 g (0.49 lb.)
  • DCI-GSI2 without aluminum box: approx. 28 g (0.06 lb.)
Temperature range
  • -40 ... +85 ºC (-40 ... +185 ºF) operating temperature
  • -40 ... +105 °C (-40 ... +221 °F) operating temperature on request
  • -65 ... +125 ºC (-85 ... +257 ºF) storage temperature
Electrical characteristics Power supply
  • 4.3 ... 30 V (38 V transient)
Protection
  • Protected against reverse battery up to -32 V
Power consumption 1)
  • 4 W typ. at room temperature, 12 V, and 1 GBit/s Ethernet. Using 100 Mbit/s Ethernet instead of 1 GBit/s saves about 0.7 W
  • 30 mW typ. in standby mode
1) 如果使用带有 MPC5xxx 微控制器的 JTAG/Nexus。
