K-line interfaces for connecting the vehicle and the PC

A K-line interface (level converter) is required for connecting the vehicle to the PC (ALADIN). It is available both with a USB interface and with a RS232 (COM1) port. Their is also a bluetooth interface available. Depending on the vehicle type, you might need an adapter connector in the vehicle. Once you have installed ALADIN and connected the interface, your diagnostic system is ready for operation.

Always install ALADIN first before connecting the K-line interface to the USB port or the serial interface of your PC.

The K-line interface with the RS232 interface is compatible with the transmission control units E200, E300, E300.1 and the diagnostic software tools DIWAgnosis, DIANA and ALADIN. You can order the K-line interface with a serial interface under the
order no.: 151.00152911.

Turn your PC off. Connect the serial RS232 connector (image to the left) to the serial port on your PC (image in the center). Always use the serial port COM1. This requirement is met automatically in PCs with only one serial port. Connect the diagnostic connector (image to the right) to the diagnostic port in the vehicle. Depending on the vehicle, you might need an adapter connector.

If your PC is not equipped with a serial interface, always use the K-line interface with a USB interface. We do not recommend using PCMCIA extension cards. For further information on adapter connectors, please see: Adapter

The K-line USB interface is compatible with the transmission control units E300, E300.1 and the diagnostic software tools DIANA and ALADIN.
All connections of the USB interface are protected against wrong polarity connection. Power is supplied via the USB port. An additional power supply unit is not required. You can order the K-line USB interface under the

order no.: 151.00202110.

First of all, install ALADIN. Turn your PC off. Connect the USB cable and the diagnostic cable to the K-line USB interface (image to the left). Connect the USB cable to a free USB port on your PC (image in the center). Connect the diagnostic connector (image to the right) to the diagnostic port in the vehicle. Depending on the vehicle, you might need an adapter connector. For further information on adapter connectors, please see: Adapter

Once you have connected the K-line USB interface to your PC, install the corresponding Windows driver.
