Wiring guidelines for the CANopen interface
The CAN network is designed in a linear structure.
}
The overall line length and the length of the stub lines depend on the transmission rate
and on the cable properties (cable resistance and cable capacitance).
}
The signal lines must be terminated with resistors on the first and last subscriber.
}
A characteristic impedance of 120 Ohm is acceptable for bus lengths up to 40 m.
