Her forsøger vi at tilbyde dig præcise forklaringer til tekniske termer, der ofte vises på denne hjemmeside.


Den “Controller Area Networkbus is a relatively recent (by automotive standards) way for control units to talk to each other, and is nowadays (since the mid-2000s) also used to perform diagnostic functions. It has, in fact, been mandatory for new vehicles in certain markets since 2008. To talk to an ECU via CAN bus, you need a K+CAN interface.


Engine Control Unit” eller “Electronic Control Unit”. Det er de computere, der styrer din bil. There is usually one for every major subsystem, such as engine, drivetrain, bremser, airbags, etc. When performing a diagnostic session, these are the units you want to talk with.


Future Technology Devices Internationalis a manufacturer of USB-to-serial converters. FTDI chips are generally more flexible than other brands when it comes to unusual modes of communication, a feature that is very important when talking to motor vehicles. CASCADE understøtter kun diagnostiske grænseflader til FTDI chips.

K/L (also known asK line”)

K/L is a mode of data transfer that uses so-calledUART signalling”, which is similar to a legacy PC serial port, although with different voltage levels. K / L har været almindeligt anvendt i køretøjer til midten af ​​2000'erne og er stadig ofte til sekundære systemer såsom bremser eller airbags. To talk to an ECU through K/L, you need a K/L or K+CAN interface.
