NOTE
If the first or last device in the bus cable is not a PME device, a 120 W re-
sistor must be connected to each of these external devices.
The baudrate of all devices must be identical to that of the CAN master.
The baudrate must be reduced for greater line lengths according to the
CAN specifications.
