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).

25.3.2Connecting 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):
