Always the right solution for your productivity

Shaping the future:
TSN Hardware + TSN Software

With the increasing automation of vehicles and the expansion of industrial digitalization, the demand for convergent networks and time-precise communication is growing. Time-Sensitive Networks (TSN) is a technical basis for future-proof solutions.

As experts for time-sensitive network solutions and specialists in E/E automotive development, TSN Systems supplies high-precision measurement and analysis technology: TSN Box, TSN Tools, TSN Switch, TSN Media Converter.

TSN Box is the hardware physical interface to the network and can be configured as either a transparent TAP or as an active network participant or emulator, for example TSN Talker/Listener or SOME/IP endpoint. Paired with the platform-independent TSN Tools software, it provides high-level analysis and visualization to keep track of things at all times.

Both the hardware and software are scalable and can be used in several different scenarios.

In addition, TSN Switch and TSN Media Converter offer solutions in the laboratory and vehicle for Automotive Ethernet, gPTP and AVB.

TSN Box 3.1

Hardware Interface for Automotive and Industry TSN Test & Measurement Applications

The TSN Box 3.1 is designed to assist with automotive network development, particularly in the context of next generation zonal architectures, as well as with planning and analysis of modern field bus systems in industrial automation based on OPC-UA/TSN.

The TSN Box is a highly flexible precision device that supports a large amount of use cases in the TSN Ethernet realm. In general, the use cases can be divided into two different areas:

  • Signal analysis/TAP device: TSN Box serves as transparent link into existing Ethernet connections. With its unique DUT-sync feature, powerful correlations between packet timestamps and network-based presentation timestamps are possible. In addition, other inputs such as SMA events or digital/analog audio input can be timestamped for coherent analysis in TSN Tools or even Wireshark.
  • Signal generation: TSN Box supports many features to generate time-sensitive signals for RESTNet emulation or low-level testing. Whether gPTP master/slave, AVB audio and video, cyclic Qbv traffic, SOME/IP or time sensitive PCAPNG replay, TSN Box can manage even the most complex scenarios.

TSN Media Converter M10

Automotive Ethernet Physical Layer Converter with Auto-Negotiation Algorithmus

The TSN Systems M10 automotive media converter is a highly flexible tool for use in multiple environments like the lab, car or HIL.

Simple, small and flexible, it seamlessly converts 1000BASE-T and 1000BASE-T1 connections, and is also 100Mbps capable. No packets are buffered or filtered and can be seen as a transparent link. For convenience, all settings are intuitively hardware adjustable without a tethered configuration PC.

T1 port speeds and master/slave settings can be manually forced with switches, or for convenience use a novel auto-negotiation method that does not rely on vendor-proprietary methods but compatible with all T1 PHYs on the market.

In Auto mode, the T1 link will automatically negotiate with its link partner without the user having to investigate the settings or use trial and error. This has been found to be a massive time-saver for use in complex and distributed systems.

Firmware can be updated using a provided USB connection, as well as terminal access for more detailed inspection.

Core features include:

  • 1 x IEEE 100/1000BASE-T1 port
  • 1 x IEEE 100/1000BASE-T port
  • 1 x Micro-USB connector for firmware updates & terminal access
  • Fully TSN compliant
  • Instant startup for in-vehicle use as soon as power is applied
  • Small dimensions, full metal case for environmental and EMC protection
  • Status LED’s indicates mode, speed and link status
  • Wide power range from 12V-42VDC for use in practically any application
  • Twin power jacks for use with either common DC barrel connectors or a lockable Phoenix connection for powering from other sources
  • T1 connectors compatible with all TSN Systems products
