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):
