Wiring the CAN bus

5.5.3 Wiring the CAN bus
Wiring must meet the following requirements:
The CAN cable complies with the specification acc. to ISO 11898−2.
ƒ
The CAN cable has twisted cores (CAN_H, CAN_L) to avoid interferences on the bus
ƒ
(Bus−Off, Bus−Heavy, etc).
When looping through the signals "CAN_HIGH" and "CAN_LOW", avoid double
ƒ
crimping. For this purpose, the Public CAN is provided with two pins each.
Stubs are <0.2 m. Ideally, stubs are avoided.
ƒ
The cable length matches the data transfer rate.
ƒ
The CAN cable runs along the LV on−board cable and is installed separately from the
ƒ
power cables.
The CAN bus is completely wired. Unwired terminals are not permissible.
ƒ
The first and last node of the CAN bus are connected to the integrated terminating
ƒ
resistor.
