The Capture Module Ethernet Combo can be used to capture the traffic from 1 x 1000BASE-T1 line (between two DUTs) and 2 x 100BASE-T1 (between four DUTs) lines correspondingly.

The traffic is captured without causing interference on the network and is delivered with a 40 ns resolution hardware time stamp, making the analysis of AVB/ TSN traffic possible.

All logged data are provided in standard Ethernet frames via the Technically Enhanced Capture Modules Protocol (TECMP). This protocol enables traceability of the source of traffic, on-the-source timestamp, packet counter, etc., making Ethernet the ideal logging network. The PLP protocol is supported, in addition. The Capture Module Ethernet Combo emits messages timestamped with 40ns resolution, providing a fast and efficient solution supported by its Extended Power Mode for car integration. Messages are sent within the PDUs of Ethernet MAC II frames via 100BASE-T1 and 1000BASE-T1.

Several devices can be used to capture data on your setup, as soon as more Ethernet ports are needed, or in case other IVN technologies have to be captured. The built-in synchronization using 802.1AS allows a simultaneous use of the Capture Module Ethernet Combo together with other IVN2Eth Capture Modules. This means that the cascading with any other device within the Capture Modules group of Technica Engineering is possible, but also with third party hardware and software.

Via the built-in webserver of the Capture Module Ethernet Combo, the device can easily be configured on a browser website. Additionally, it includes a rotary switch for the manual configuration of its IP addresses.

The Capture Module Ethernet Combo includes a Startup Buffer and the High-Speed Startup feature, so the initial startup information is instantly captured. This way, the device is able to record all the important information emitted by the vehicle systems, without missing any message in the communication between devices.

Technica Engineering´s Capture Modules are a highly innovative and unique traffic capturing solution, with exclusive characteristics adapted to the current technological requirements in the automotive field.

Our new generation of devices is developed to fulfil the most critical requirements in contemporary automotive ECU development, which is the reason why our products are used by the mainstream OEMs in the field.

The variety of additional features makes the Capture Module Ethernet Combo a great choice for general-purpose testing.
