For lengths up to 1000 m a can bus repeater is required and another one for lengths up to 1500 m.
Can bus cable length.
The maximum can cable length considering cable and transceiver propagation delay an interesting discussion from the canlist.
Bus length l cable stub length l node distance d 1 mbit sec.
Er wurde 1983 vom unternehmen bosch entwickelt und 1986 zusammen mit intel vorgestellt.
Cable lengths of up to 500 m are possible.
40 meters 131 feet 0 3 meters 1 foot 40 meters 131 2 feet 500 kbits sec.
If you need longer cables for your application confirm with the ni product documentation for your device the xnet manual and or the sae j2411 or iso 11898 cia ds 102 and devicenet specifications.
Sein zweck ist es kabelbäume zu reduzieren und hiermit kosten und gewicht zu sparen.
Iso 11898 3 also called low speed or fault tolerant can up to 125 kbit s uses a linear bus star bus or multiple star buses connected by a linear bus and is terminated at each node by a fraction of the overall termination resistance.
Rule of thumb for coax propagation is 6 inches in 1ns ugh non si units let s say 6ns m.

Details of a typical can node the high speed iso 11898 standard specifications are given for a maximum signaling rate of 1 mbps with a bus length of 40 m and a maximum of 30 nodes.
The signal has to go out and back so we have to halve that giving 500ns.
One output line is optional and ordinarily not use.
That would give a bus length of about 85m.
The overall termination resistance should be close to but not less than 100 ω.
500 meters 1640 feet 0 3 meters 1 foot 500 meters 1640 feet 50 kbits sec.
It also recommends a maximum un terminated stub length of 0 3 m.
Zur damaligen zeit konnte die gesamtlänge aller kabel im kraftfahrzeug ohne can bis zu 2 km betragen.
You may need to create your own cable or purchase from a third party.
Can bus data cables shielded sae j1939 11.
Though the iso11898 standard specifies a maximum bus length of 40m and maximum stub length of 0 3m at 1mbps.
