Requirements for CAN communication with the vehicle

The length of the cables must not exceed 30 metres (main cable) between connector
C259 in the truck and the control unit with the other termination resistor. If more than
one control unit is connected, the length of the cables between the main cable and
control unit should not exceed 3 metres. The cables should be as short as possible to
minimise the effect of electromagnetic interference. The number of control units in
the external CAN network should not exceed 9. The topology is essentially a bus ca-
ble with the nodes connected to the CAN bus with at least 0.1 metre between each
node. The figure shows the principle of the external CAN network topology.
