LIN Bus Signal Monitoring (Applies to models with the /VE
option)
You can monitor CAN and LIN bus signals using the 720241 CAN & LIN Bus Monitor Module. This feature is
available only on models with the /VE option.
• CH1, CH3: CAN signals
• CH2, CH4: LIN signals
For details on the CAN bus signal monitoring feature, see “CAN Bus Signal Monitoring (Applies to models with
the /VE option).”

This section explains the LIN bus signal monitoring feature.
The instrument uses the module to read the ISO-9141 signal, that is transferred on the LIN bus and then extracts
the specified portion of the LIN frame (LIN data), converts it to time series data, and displays its waveform. The
waveforms of up to 60 sub channels can be displayed. You can also use the LIN descriptor files (LDF) that are
described in the LIN configuration language specification to specify (define) LIN data.
For LIN bus signal monitoring using a CAN & LIN Bus Monitor Module, the items that have to be set include
port settings, frame settings, data extraction conditions, sub channel display range, unit of measurement, trace
settings, and scaling.
The instrument requires the following processing times to read data frames transferred on the LIN bus. New
frames that the instrument receives during these processing times may be discarded.

You can select whether to display each port’s input signal waveforms. Each port corresponds to CH1 to CH4.
• ON: Shows the waveform
• OFF: Hides the waveform
