23 CAN/LIN Triggering and Serial Decode
Interpreting CAN Decode
• Frame ID appears in hex digits in yellow. Frames of 11 or 29 bits are
automatically detected.
• Remote frame (RMT) appears in green.
• Data length code (DLC) appears in blue for data frames and green for remote
frames.
• Data bytes appear in hex digits in white for data frames.
• Cyclic redundancy check (CRC) appears in hex digits in blue when valid, or in
red to indicate that the oscilloscope's hardware decode calculated a CRC that
is different from the incoming CRC data stream.
• Angled waveforms show an active bus (inside a packet/frame).
• Mid-level blue lines show an idle bus.
• Decoded text is truncated at the end of the associated frame when there is
insufficient space within frame boundaries.
• Pink vertical bars indicate you need to expand the horizontal scale (and run
again) to see decode.
• Red dots in the decode line indicate that there is data that is not being
displayed. Scroll or expand the horizontal scale to view the information.
