The OBDSTAR M040 is the adapter cable for the round 10-pin diagnostic port found on BMW motorcycles. On the vehicle side, it features a cylindrical connector with ten pins; on the device side, a standard 16-pin OBD2 (J1962)-connector to which you connect your diagnostic scanner.
BMW retained this round connector on its motorcycles for many years, at a time when the automotive OBD2 connector was not yet standard on two-wheelers. Depending on model and year of manufacture, communication runs via the K-line or via the CAN-bus. The cable contains no active electronics: the signal lines are routed directly through the connector, so the cable functions purely as a passive pin translator. Through this connection, you access the engine control unit and other systems connected to the diagnostic bus. Which functions and protocols are available depends on your specific model and year of manufacture and is determined by your own device's software; the cable itself adds no additional protocol support.
