XETK – XCP-compliant ECU Interface

ETK and XETK differ in the way the connection between ECU and host application is set up. ETK-ECUs are connected to the PC by means of an interface module which provides for protocol handling. In contrast, XETKs implement a full functional Ethernet interface on board to facilitate direct connection to the PC. XETKs utilize the XCP-on-Ethernet protocol for data transfer. By use of this standard, they can be integrated easily into existing tool environments.

The XETK is capable of handling up to four XCP communication channels simultaneously. This facilitates concurrent access by several PC-based software applications to an XETK-equipped ECU. Several XETK data lines can be connected to a host computer through a network module. This option is of interest in the calibration of systems which are either distributed across several ECUs or implemented by an ECU equipped with several processors. In such cases, the XETK data of the various ECUs can be reconciled by means of a hardware-based time synchronization process.
