Among other very good devices from for instance Intrepid CS and Vector, we found the Capture Module devices from Technica to be very powerful and flexible. They eliminate lost messages caused by slow startups or performance issues.

‍

Here's what makes them stand out:

‍

Precise Time Synchronization: Capture Modules ensure messages from various bus systems have the same timestamp (thanks to 802.1AS) for seamless analysis.

‍

No Data Bursts: Capture Modules load balance traffic, preventing data bursts that can lead to information loss. Fast startup and a dedicated buffer guarantee capturing all messages from ECU startup.

‍

Modular & Scalable: Capture all in-vehicle traffic with reliable timestamps using this modular, scalable system.

‍

Non-Intrusive & High-Resolution: Capture traffic without network interference, delivering data with a 40ns hardware timestamp for detailed AVB/TSN analysis.

‍

Safety-Compliant: Use these modules in any vehicle, regardless of ASIL level (as long as the system follows best practices).

‍

Multi-Device Synchronization: 802.1AS ensures time synchronization in multi-device setups, allowing cascading for capturing data from many ports or different bus topologies.

‍

Easy Data Access: Capture Modules provide logged data in standard Ethernet frames via TECMP or CMP for easy access and analysis using any Ethernet-capable device.

‍

Simple Configuration: Manage your Capture Modules through a built-in web server or a rotary switch for manual IP configuration.
