Baud rate / length of bus cable

The length of the bus cable depends on the baud rate used:

Baud rate [kbps]

Length [m]

9.6 ... 93.75

1200

187.5

1000

500

400

1500

200

3000 ... 12000

100

)

Note!

The baud rate depending of the data volume, cycle time and number of nodes
should only be selected as high as required for the application.

I

Tip!

For high baud rates we recommend to consider the application of optical
fibres.

Advantages of optical fibres:

ƒ

Electromagnetic interferences on the transmission path remain ineffective.

ƒ

Bus lengths of several kilometres are also possible with higher baud rates.
The bus length is
– independent of the baud rate.
– dependent on the optical fibre used.
