Note 1 Due to possible high currents in the wiring harness the individual ground potential of
control units may differ up to several volts. This difference will also appear between
a transmitting and receiving control unit as common mode voltage and does not in-
fluence the differential bus signal if the common mode voltage is within the common
mode limits.
Note 2 The arbitration process will allow 1 Mbit/s operation only in small networks and re-
duced wire length. As example a so-called private CAN, a short point-to-point con-
nection (less than 10 m) between only two nodes can be operated at 1 Mbit/s.
Note 3 For typical network size and topology (network with stub wires) and more than two
nodes the practical limit is 500 kbit/s.
