Goepel Electronic has expanded its range of LIN communication controllers for testing ECUs (electronic control units) with the introduction of the PXI 3078, a module that provides two LIN bus or K-Line interfaces and supports LIN specifications 1.3, 2.0, and 2.1.

Bus communications includes all LIN-typical message types and diagnosis services like event-triggered frames, sporadic frames, unconditional frames, and diagnostic frames. Configured as a K-Line interface, the module supports the diagnosis protocols KWP 2000, KWP 1281, and ISO 9141 (Ford). Extended command sets such as stimuli/response runs, ramps, or table functions are available as software add-on modules.

The PXI 3078 offers complete galvanic insulation between the LIN bus/K-Line interface and the host interface, which prevents compensating current from occurring between the test system's supply and the unit under test's supply. Therefore, the module can be used in system tests that are performed directly at the vehicle electrical system. In addition, the transceivers' supply is switchable via software, either internally or externally over the LIN bus. The bus termination for master or slave operations can also be switched on/off via software.
