Thanks Erik for the link
in this appnote it says: The symbol “l” denotes the stub length. Keep this distance as short as possible. Keeping a stub’s electrical length below one-fourth of the signal’s transition time ensures that the stub behaves as a lumped load and not as a separate transmission line. If I set Transition Time 100nsec, which is quite realistic for a 125kBit CAN environment, I get 7.5m stub length. I personally would not go that far.. Werner PS. RS485 allows much higher speeds than CAN (1MBits max) also much longer lines at a given speed (30m max for 1MBit CAN). |
