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

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

VN8911:

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

VN8914:

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
