Which topologies are recommended?

The following topologies achieve the best results with regard to signal quality.

5.3.1

Line topology (daisy chain)

All devices are connected in single row without a stub line.

Device 1

Trunk

Device 2

Device n

5.3.2

Line topology with stub lines

The trunk line of the network is connected directly to the next device. If this is not possible, use a stub line.

Avoid stub lines as much as possible and keep them short. Please note the maximum stub line length that

depends on the baud rate.

Device 2

Trunk

Stub
