The CM 1000 High MATEnet is an active tap device that is used to capture the traffic with 6 ports and up to 6 point-to-point 100/1000BASE-T1 connections (12 ports in total). The traffic is captured without causing interference on the network and delivered with a 40 ns resolution hardware time stamp, allowing for AVB/TSN traffic analysis. With a traffic shaping feature included, the logged output of many bus channels is steadily transferred to a data logger or test PC, eliminating bursts that might lead to a loss of data.

The Capture Module 1000 High provides all logged data in standard Ethernet frames via the Technically Enhanced Capture Modules Protocol (TECMP) and thus allows for traceability of the source of traffic, on-the-source timestamp, packet counter, etc., making Ethernet the ideal logging network. The Capture Module 1000 High emits messages timestamped with 40ns resolution, providing a fast and efficient solution that is supported by its extended Power Mode for car integration. These messages are sent within the PDUs of Ethernet MAC II frames via 1000BASE-T1 (or Gigabit Ethernet).

Several devices can be used on the same setup, if further 1000BASE-T1 ports are required, or if you want to log other bus systems. The built-in-synchronization using 802.1AS enables a time-synchronized, simultaneous use with other devices. This also enables the cascading of multiple Capture Modules via the Enhanced Ethernet Switch.

Via the built-in webserver of the Capture Module 1000 High, the device can easily be configured. Additionally, it includes a rotary switch for the manual configuration of its IP Addresses.

The Capture Module 1000 High includes a Startup buffer and High-Speed Startup feature, so the initial Startup information of the network is not lost. This way, the device can record all the important information emitted by the vehicle systems, without missing any message in the communication between devices.

Via the configuration website, the Marvell 88Q2112 A2 PHY’s “IEEE mode”, as well as the “Legacy mode” are supported by the Capture Module 1000 High. For a detailed technical description, please check the User Manual.
