Receiver: simple comparator (input = inverted), output: open-collector transistor. In the picture: simplified schematics of LIN BUS device transmitter/receiver part. After receiving directions, current device replies with network reply message. Network operation: Master unit gives directions for current device to reply. network load: power-up resistors in Master and Power-up modules.communication via 1 wire (active = low).These are slow (and not very secure – signal lines are not doubled) serial interfaces, that’s why they are used to control peripheral functions and management of mechanisms.
