HS Interfaces

Save as PDF

The diagnostic interfaces of the HS family are based on a 32-bit microcontroller platform and are particularly suitable for use in the higher performance range such as, for example, challenging diagnostic tasks and flash applications on the entire vehicle. The HS interfaces are characterized by very secure communication mechanisms regardless of the PC operating system. Users have diagnostic interfaces at their disposal with various wired or wireless interfaces to the PC.

Areas of Application

  • Diagnostic applications for engineering, manufacturing and after-sales service
  • Test and validation
  • Fast and reliable flash programming
  • Functional ECU tests and communication tests
  • Data logging during manufacturing, in development, in fleet tests
  • Future-proof diagnostic solutions with DoIP (Diagnostics over IP)
  • Suitable for cars and commercial vehicle


  • VCIs tailored to the different areas of application
  • Data preprocessing and protocol handling in the interface
  • Galvanic isolation
  • Virtual Machine (VM) for programmable sequences
  • Linux operating system for the integration of customer-specific applications
  • Large number of standardized and OEM-specific vehicle protocols available
  • Several independent channels: CAN, K-line, FlexRay, Ethernet
  • Interface to the host PC over USB, Bluetooth, LAN or WLAN (IEEE802.11 a/b/g/n/h)

The right VCI for every use case

The HSX interfaces and the HSC in particular are perfect for multi-link communication in diagnostic and flash applications on the entire vehicle as protocol processing takes place on the interface with a 32-bit high-performance CPU. With the compact design of the HSC and interfaces to the PC over WLAN and LAN as well as interfaces to the vehicle over CAN, K-line and Ethernet, the VCI is particularly well suited for future-proof mobile manufacturing and after-sales service applications. With the addition of up to two extra boards, the Multibus VCI HSX Breakout can quickly adapt the number of communication channels available on the PC system to the relevant application. Modules with two additional CAN or FlexRay interfaces each are available. With the integrated test sockets , the VCI is optimally equipped for universal use in engineering and testing.The HSX-S is a small and robust version of HSX devices. The VCI has two CAN interfaces as well as K- and L-line. An OBD connector cable gives access to vehicles. The HSX-S can communicate with the host PC via USB or Ethernet.

Standardized and powerful Programming Interfaces

The VCIs of the HS family can be up dated with software upgrades and are thus always equipped for future applications. This is also the way to realize customer-specific software solutions. Based on the D-PDU API as a standardized programming interface, the Diagnostic Tool Set DTS from Softing can deliver a complete solution compliant with the MCD-3D standard (ISO 22900-3) and ODX technology.
