LIN Slave Mode
In the LIN Slave Mode, the 100BASET1_SPY LIN port acts as the Slave in the LIN protocol communica-
tion. 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:
Note:
The configuration must be set through the 100BASET1_SPY Fast Ethernet Port (Host).
Note:
The IDs from 0x3C to 0x3F are reserved according to the LIN specification, and cannot be used.
