CAN bus network
J1939 Node or CAN Layer 2 Node
The CAN bus network requires terminating resistors for both network ends.
• SAE J1939-11: 40 m (131'2"), stubs max. 1 m (3'3") at 250 kbps
• SAE J1939-15: 40 m (131'2"), stubs max. 3 m (9'10") at 250 kbps
• CAN (Layer 2): 5000 m (16,404'2") at 10 kbps (with repeaters).
The transmission distance is reduced to 25 m (82') at
the maximum baud rate of 1 Mbps.
The maximum distance also depends on the specification of other
connected nodes.
