The system offers six TAPs with a total of twelve H-MTD ports and two SFP+ uplinks for bandwidths of up to 2 × 10 Gbit/s. All captured data is transmitted via standardized protocols such as ASAM CMP v1.0 and PLP. Timestamping is performed with nanosecond resolution, complemented by synchronization via gPTP/PTP, enabling precise alignment of multiple interfaces.
Configuration is fully web-based or via REST API, with import and export functions simplifying the transfer of settings in complex test environments. A 4 GB buffer with timestamp recalibration ensures that no data is lost even under high load. In addition to pure mirroring, the device supports functions such as traffic shaping, packet filtering, and targeted injections for diagnostic purposes. The Plus variant forwards traffic even without power supply, increasing operational safety.
The FL3X TAP captures all Ethernet packets and layers, including AVB/TSN, making it suitable for modern vehicle architecture. Its combination of technical precision and ease of use makes it a practical tool for developers and test engineers. In ECU communication validation, the FL3X TAP enables lossless capture of traffic between control units to verify protocol compliance and timing.
For infotainment and driver assistance systems relying on AVB and TSN, nanosecond-accurate timestamping provides precise evaluation of real-time capability. Even in cases of sporadic network errors, the FL3X TAP delivers complete packet data to quickly identify causes such as faulty frames or timing issues. In hardware-in-the-loop environments, the device can be configured automatically via REST API and integrated seamlessly into test workflows.
Outlook:
STAR® is already working on the next generation: the FL3X TAP 10GBASE-T1. This device will support two TAP channels for 10GBASE-T1 and is expected to be available in the second quarter of 2026, taking high-speed Ethernet analysis in the automotive sector to a new level.
