temporary connection to the CCN network or to computers
equipped with CCN software like the Service Tool. Also on
TB3 there are screw connections that can be used for more
permanent CCN connections.
In the following tables the structure of the tables which are
used with the Service Tool as well as the names and data that
are included in each table are shown. As a reference the equiv-
