LIN trigger
Before you set up the trigger, make sure that the bus is configured correctly. See
Chapter 12.6.2, "LIN configuration"
To trigger on LIN signals:
1. Press the [Protocol] key in the Analysis area of the front panel.
2. Select the bus that is configured for LIN.
3. Select "Trigger".
This selection has several effects:
● Enables decoding, if necessary.
● Sets the "Trigger Type" to "Serial Bus" and the trigger source to the selected
bus.
● Displays the "LIN
Trigger" condition in the dialog box, below the protocol setup.
4. At "LIN
Trigger", select the required trigger type:
● "Start of Frame": stop bit of the sync field
● "Wake Up": after a wakeup frame
● "Error": checksum, parity or synchronization
● "Identifier": specific message identifier or identifier range
● "Identifier and Data": combination of identifier and data condition
5. If "Identifier" or "Identifier and Data" is selected, the LIN trigger setup dialog
expands to define the serial pattern.
