- The best type of cables for CAN bus connections is the twisted pair; if it is
necessary to increase the immunity of the system to disturbances, a good
choice would be to use shielded cables, where the shield is connected to the
frame of the truck. Sometimes it is sufficient a not shielded two-wire cable or
a duplex cable.
- In a system like an industrial truck, where power cables carry currents of
hundreds of Ampere, voltage drops due to the impedance of the cables may
be considerable, and that could cause errors on the data transmitted through
the CAN wires. The following figures show an overview of wrong and right
layouts for the routing of CAN connected systems.
