LIN Slave Mode
In the LIN Slave Mode, the 100BASET1_SPY_12_Port LIN port acts as the Slave in the
LIN protocol communication. In this case, the 100BASET1_SPY LIN port will answer to
a Master LIN ID, according to an internal ID table. If the Master ID request is not in that
table, there will not be any answer from 100BASET1_SPY LIN port. The information of
that table can be updated setting the ID, the Length and the payload. The following
table shows the structure of the Ethernet LIN Slave Configuration frame used for this
purpose:
