5 Installation Description of the LON-Network

The installation can be carried out with the cables and distributors pre-manu-

factured by HERMOS (see 6. Accessories). Your own cabling is also possible

when the following points are noticed.

5.1 Transmission Medium

The bus cable is realized through an economy-priced twisted pair cable. With

carried along operation voltage with 4 cores.

For shielded cables, the shield has to be connected on both sides.

Realization with optical fibre, radio and infrared is also possible.

5.2 Network Topology

There are two possiblities of network topology:

-Free topology

-Bus-topology

The free topology allows a constellation in line-, star, ring- or tree-structure.

So it is able to correspond to the geometrical demands.

A mixed architecture is also possible.

Only one connector is required.

On account of the mode of transmission, it cannot be connected the wrong way

round.
