CAN relationship between cable length / baud rate
5.4.3.2 CAN-Bus-topology
•
A bus segment can interconnect up to 32 slaves.
•
Multiple bus segments can be connected with the use of repeaters
(bi-directional amplifiers).
A bus segment must be provided with a cable termination (120
) at both
ends.
These terminations must be connected inside the plug, directly between
PINs 3 and 7.

The use of repeaters enables the maximum cable length to be
increased.
Repeaters can also be used for galvanic isolation. For more
details, please consult the documentation for repeaters pro-
vided by manufacturer.
Make sure to follow the recommendations provided by CiA
(CAN in Automation) at http://www.can-cia.org.
→
The bus segment must be terminated at both ends.
No more than two terminations must be provided for each bus
segment.
Operation without correct cable termination can cause transmis-
sion errors.
