Bus Structure

The bus structure is a line structure where each bus segment
will be blanked off with characteristic impedance on both ends.
Branches can be build up over a bi-directional signal amplifier,
so called repeater. Other than that branches are not permitted
(no tree topology). The max. stub to a user is not allowed to ex-
ceed 30 cm (12 inches).

The following figures show a few examples for a possible set-
up of bus topologies. The meaning of the symbols is: : bus
user, : repeater and : bus termination.
