Therefore the practical maximum number of nodes, bus length and stub length are typically much lower. esd has concentrated her recommendations concerning CAN wiring on the specifications of the ISO 11898-2. Thus this wiring hints forgoes to describe the special features of the derived standards CANopen, ARINC825, DeviceNet and NMEA2000. -

Thus the shielding is interrupted. -
