Modular Network Interface

VN8900 - Modular FlexRay/CAN FD/LIN/J1708/K-Line Network Interface with up to 8 Channels

The VN8900 network interface is a modular designed interface hardware with various possible channel combinations for CAN FD, LIN, FlexRay, J1708 and K-Line.

A particular focus here is on parallel access to multiple bus channels and I/Os with high requirements on real-time and latencies also in standalone operating mode.


  • Keypad for standalone operating mode
  • Network interface with integrated real-time computer
  • Modular concept allows a wide range of channel combinations by simply interchangeable transceivers for different bus physics
  • Optimal performance for CANoe/CANape/ CANalyzer applications with CAN, CAN FD, FlexRay, LIN, J1708 and K-Line bus access
  • Real-time bypassing and rapid prototyping platform in combination with CANape
  • SSD/CFast memory
  • Integrated analog/digital I/O interface
  • Minimal latency times and synchronized interfaces
  • Easy to configure via USB plug & play or Ethernet interface

Base Units and Plug-in Modules

A VN8900 system consists of a base unit and a plug-in module

Base Units:

  • VN8911: Base unit with integrated Intel ATOM processsor
  • VN8914: High performance base unit with integrated Intel Core-i7 processor of the 6th generation.

The base units contain the component “Extended Real Time” (ERT). This component improves the latency and the determinism of CANoe and CANape. It also executes predefined functions under real-time conditions.   

Plug-in Modules:

  • VN8970/VN8972: FlexRay/CAN/CAN FD/LIN/J1708/K-Line modules with analog/digital IO expandability

Application Areas


  • Mobile, stationary as well as standalone applications
  • Applications where access to several bus channels and I/Os is required
  • Suitable for environments with voltage dips and extreme temperature conditions


  • Stationary as well as standalone applications
  • Applications where access to several bus channels and I/Os is required
  • Applications, which need high performance data throughput
  • Test stands with extensive CANoe configurations or MATLAB simulations
  • Huge laboratory test environment
