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.
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.
