Setting the Node-ID
If the Node-ID of the sensor has to be changed, the LSS Configure Node-ID command must be used.

* the Node-ID value to be configured, within 1..127 (126 in this example).
** if value is 1, it means Node-ID out of range, i.e. the command was not accepted.
Setting the baud rate
If the baud rate of the sensor has to be changed, the LSS Configure Bit Timing Parameters command must be used.

Refer to the Table index in the LSS Configure Bit Timing Parameters section for details.
** If the value is 1 means that the bit timing is not supported; the command was not accepted.
Storing configuration settings
To save the previously configured Node-ID and Baud rate permanently (to non-volatile memory of the device) the LSS
Store Configuration command must be used.

Verifying configuration setting
To check if the configuration settings of the device have been correctly executed and stored, proceed as follows:
1. power off the device
2. set the baud rate of the CAN bus to the correct value
3. power on the device
If the boot-up message is received, it means that the device baud rate setting is correct. The Node-ID of the device is
contained inside the COB-ID of the message (boot-up COB-ID = 700h + Node-ID).
The format of the boot-up message is specified in the following figure.
