The Capture Module CAN Combo is an active tap device that is used to capture traffic from the conventional CAN busses, as well as CAN-FD, FlexRay and RS-232. The traffic is captured without causing interference on the network and is delivered with a 40 ns resolution hardware time stamp. With a traffic shaping feature included, the logged output of many bus channels is transferred to a data logger or test PC in a steady manor, eliminating bursts that might lead to a loss of data.

All logged data are provided in standard Ethernet frames via the open 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 CAN 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 (or Standard Ethernet).

Several devices can be used to capture data on the same setup, as soon as more CAN 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 CAN Combo together with the other IVN2Eth Capture Modules. This means that the cascading with any other device within Capture Modules group of Technica Engineering is possible, but also with other products like the Enhanced Ethernet Switch.

Via the built-in webserver of the Capture Module CAN 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 CAN Combo includes a Startup Buffer and High-Speed Startup feature (<200 ms), so the initial startup information of the system is instantly captured. This way, the device is able to record all the important information emitted by the network, 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 active tap 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 of OEMs in the field.

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