Typical Configurations
3.1
Tree topology
The IEEE1394a technology allows to create extended networks with up to 63 partici-
pants. The attendance of one branch must not be more than 16 devices.
The tree-topology allows the construction of a network system by connecting one bus
participant with two further ones.

3.2
Line topology
The line topology allows the construction of a network system by connecting one bus
participant with one other participant.
The maximum number of point-to-point connections from one bus participant to any oth-
er participant in the IEEE1394 bus is limited to 15 – which means that not more than 16
devices are allowed to be connected in series (line topology)
This is the most used topology since only in rare cases the number of devices in a mea-
suring system exceed 16 devices.
