CAN bus wiring
Note the following when connecting the CAN bus:
–
Each bus end must be fitted with a terminating resistor of 120 Ω (see
drawing).
–
The maximum wire length depends on the bit rate:
Bit rate

all stubs
1 Mbit/s
25 m (82')
1.5 m (5')
7.5 m (25')
800 kbit/s 50 m (164')
2.5 m (8')
12.5 m (41')
500 kbit/s 100 m (328')
5.5 m (18')
27.5 m (90')
250 kbit/s 250 m (820')
11 m (36')
55 m (180')
125 kbit/s
500 m (1,640')
22 m (72')
110 m (360')
50 kbit/s
1,000 m (3,280') 55 m (180')
275 m (902')
–
Only use cables that are specified by the manufacturer for use in the
CAN bus.
