3.1.2

DATA LINK LAYER

This provides for the reliable transfer of information across the physical layer. It includes the message structure, framing and error control. 3.1.3

DOMINANT SIGNAL

The driven and low voltage state of the LIN bus. If multiple devices access the bus, this state dominates the recessive or non-driven state. 3.1.4

“DORMANT” STATE

The state in which the slave task state machine is waiting for reception of the Break / Synch sequence. 3.1.5

MASTER NODE

Responsible for initiating all message traffic. See the Glossary of the LIN Specification Package for additional information. 3.1.6

MEDIA

The physical entity that conveys the electrical (or equivalent means of communication) signal transmission among ECUs on the network. 3.1.7

PHYSICAL LAYER

This ISO 7498 subsection consists of the media, mechanical interconnections, and transceivers that provide the interconnection between all ECU nodes. 3.1.8

PROTOCOL

The formal set of conventions or rules for the exchange of information among the ECUs. This includes the specification of the signal frame administration, frame transfer and physical layer. 3.1.9

PUBLISHER

A Master or Slave Node that is the source of the data transmitted onto the bus within a LIN message. 3.1.10 RADIATED EMISSIONS

The energy that radiates from the LIN physical layer. 3.1.11 RADIATED IMMUNITY

The level of susceptibility of physical layer components to communication errors in the presence of high energy electromagnetic fields.
