5.8 Overview of Interfaces
The table below shows an overview of the user interfaces of the
Diagnostic Software. The table is based on logical interface,
interfaces as seen from user perspective. A logical interface
can use one or more physical interface components. The DVD
has only a single RS232 port, implying that all interfaces using
this port are mutually exclusive.
