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.
11.6.1 CAN Bus Configuration
Before you configure the bus, set the correct logic level (threshold).
●
For analog channels, see
"THRESHOLD menu" on page 36.
●
For digital channels, see
"To set the threshold for logic states" on page 108. The
default value is 500 mV.
