25.3 Connections
25.3.1 Introduction
This section gives an overview of typical system
connections using the network splitter:
•
Looping through the main branch (see section 25.3.2).
•
Creating tap-offs (see section 25.3.2).
•
Connecting an external power supply (see
section 25.3.3).
25.3.2 Connecting the main branch and
creating tap-offs
See figure 25.5 for information about connecting the
main network and the tap-offs to the network splitter.

25.3.3 Connecting a power supply
This unit is powered by the network controller, via the
Praesideo system bus. But the network splitter is
delivered with a separate Kycon KPP4-P connector to
connect an external power supply to the network
splitter.
Note
The external power supply can only feed the
tap-offs and not the main network branch.
Whether it really does depends on the jumper
settings inside the network splitter.
The Kycon KPP-4P connector has four pins (see
figure 25.6):
