At the physical level, CAN is a differential signal, therefore a differential probe is rec-
ommended for decoding. Nevertheless, standard probes are also suitable to capture
the signals. The standard data rates range between 10 kBit/s and 1 MBit/s.
A CAN message primarily consists of a start bit, the frame ID (11 bit or 29 bit), the data
length code DLC, the data, a CRC, acknowledge bit, and an end bit.
