The CAN-bus makes it possible to use different data transmission rates, in which the boud rate is indirectly proportional to the length of the bus. If the network is only slightly extended, higher baud rates up to 500 kbit/s are possible. In case of larger extensions, the baud rate has to be lowered (to a min. transmission rate of 10 kbit/s). The following table explains the relationship between baud rate and length of the bus or extension of the network. In principle, bus lengths over 1000 meters should only be realized with repeaters.

Transfer rate (in kbit/s)	Bus length (in m)
500	100
250	250
125	500
62,5	1000
20	2500
10	5000

Please see the CAN bus principles chapter on page 36 in the appendix of this document as well as the instruction manuals of the connected devices for further information on CAN bus (especially on system examples and performance specifications).
