27 LIN Triggering and Protocol Decode
Interpreting LIN Decode
• Angled waveforms show an active bus (inside a packet/frame).
• Mid-level blue lines show an idle bus.
• The hexadecimal ID and parity bits (if enabled) appear in yellow. If a parity error
is detected the hexadecimal ID and parity bits (if enabled) appear in red.
• Decoded hexadecimal data values appear in white.
• The checksum appears in blue if correct, or red if incorrect.
• 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.
• Unknown bus values (undefined or error conditions) are drawn in red.
• If there is an error in the synch field, SYNC will appear in red.
• If the header exceeds the length specified in the standard, THM will appear red.
• If the total frame count exceeds the length specified in the standard, TFM will
appear red (LIN 1.3 only).
• For LIN 1.3 a wakeup signal is indicated by WAKE in blue. If the wakeup signal
is not followed by a valid wakeup delimiter a wakeup error is detected and
displayed as WUP in red.
