CAN Bus
The CAN interface is designed according to ISO 11898. It is a two-wire connection with
differential signals. ISO 11898 specifies a bus cable with two signal lines, CAN_H and
CAN_L. The lines have a rated impedance of 120 Ohm. The signal lines are connected
to a terminating resistor (120 Ohm) at both ends of the bus cable (see figure).
The total length of the bus cable must not exceed the specified lengths. The following
table indicates physical limitations valid for specific transmission rates:
Baud rate
Max. bus length
50 kBd
1000 m
125 kBd
500 m
250 kBd
250 m
500 kBd
100 m
1000 kBd
25 m
The number of bus nodes is also limited by the specification according to ISO 11898.
The limiting value is between 32 and 100 bus nodes. depending on the used cable and
transmission rate. For further information on the maximum number of bus nodes refer
to the document “CAN Physical Layer” by the user organization CiA e. V.
