LIN data bus
The Local Interconnect Network is a local system
that transfers data via a single-wire connection
at a data transfer rate of 1 - 20 kbit/s.
The transfer rate is stored in the master control
unit software. The data exchange occurs
between a master control unit and up to 16 slave
control units. The communication between the
individual subscribers is initiated exclusively by
the master control unit that can also
communicate on the CAN data bus.
