15.5 LIN Serial Decode
The following order of operations should be followed to ensure that the trigger and decode
functions are set correctly:
• Setup for LIN Signals
• LIN Decode
Setup for LIN Signals
LIN (Local Interconnect Network) signal setup consists of connecting the oscilloscope to a serial
LIN signal, specifying the signal source, threshold voltage level, baud rate, sample point, and
other LIN signal parameters.
To set up the oscilloscope to capture LIN signals:
3. Press the Decode button to turn on the DECODE menu.
4. Press the Decode softkey and select the desired slot (Decode 1 or Decode 2).
5. Press the Protocol softkey and select LIN with the Universal Knob and push the Universal
Knob to confirm.
6. Press the Signal softkey to enter the LIN SIGNAL menu.

7. Press the Source softkey and select the channel for the LIN signal.
8. Press the Threshold softkey and urn the Universal Knob to select the LIN signal threshold
voltage level. The threshold voltage level is used in decoding and it will become the trigger
level when the trigger type is set to the selected serial decode slot.
9. Press the key to return to the DECODE menu.
10. Press the Configure softkey to enter the BUS CONFIG menu.
11. Press the Baud softkey and turn the Universal Knob to select the baud rate that matches your
LIN bus signal. The LIN baud rate can be set to predefined baud rates from 600 to 19200 or a
custom baud rate from 300 to 20000. If the desired baud rate is not listed, select Custom on
the Baud softkey. Press the Custom softkey and turn the Universal Knob to set the desired
baud rate.
LIN Serial Decode
To set up LIN serial decode:
1. Press the Decode button to display the DECODE menu.
