There are, in fact, various communications formats, such as transmission by people talking, letters written in script, and electronic communications, etc. Among these, there are various plans for communications using electricity.

    AN07-00200-03E The characteristics of LIN used in the way described above, are collated and introduced in the following five points. Single master communication LIN has two types of communication nodes. One is the “master” (sender).This controls the start of all communications. The other is the slave (recipient).The slave responds to commands sent by the master.

Consequently, LIN has the advantage of using a single cable for numerous network wires, unlike CAN and FlexRay, which use twisted pair cables.

    AN07-00200-03E LIN communication flow In general LIN communication, one master communicates with numerous slaves. LINs, which adopt a bus topology, connect the master and all the slaves using a single wire, so header electrical signals sent by the master are transmitted by the wire to all the slaves. The slaves check the frame ID, and if the header is addressed to them, sent a response to the master according to the content received.
