VAS 5054A User Manual
2.3 System Overview
The diagnostic application and the associated Diagnostic Base System are installed on the
application PC. The Diagnostic Base System can access the VAS 5054A via Bluetooth or USB.
Access via Bluetooth:
After a connection to the VAS 5054A has been set up, the Bluetooth software provides a virtual
serial COM port (Bluetooth Serial Port Profile). The Diagnostic Base System uses this COM port
to communicate with the VAS 5054A. You need to specify this port when you install the
diagnostic application.
Access via USB:
You can also connect the VAS 5054A to the application PC by using the supplied USB cable.
Windows detects the VAS 5054A through Plug and Play, and automatically installs the drivers
copied when you installed the diagnostic application. Setup of the VAS 5054A is then complete
and the device is ready for use by the diagnostic application.
