LIN (Local Interconnect Network)
LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. The bus is a single master/multiple slave bus that uses a single wire to transmit data.
By using LIN, the amount of cabling required to allow components to communicate with each other is greatly reduced. This saves cost, weight and space, and makes the system more reliable, as the physical number of wires and connections is reduced.
The instruments use some of this data internally and also broadcasts it on the CANbus (Controller Area Networking) for use on the motorcycle as necessary.
Information (such as headlight main beam) is being requested continuously by the Instruments, once a confirmation of the request is recognised the instruments will react accordingly.

Example
Pressing the headlight main beam button on the switch housing (left hand handlebar) confirms to the instruments that headlight main beam is required.
The instruments confirm the data has been received correctly and that the data is valid.
Once confirmed the headlight main beam is switched on.
Triumph currently uses LIN on certain models for communication between the instruments and the following components:
Fog light button
Heated seat
Dip beam/Daytime running lights (DRL) switch (if equipped)
Mode button
Turn signal switch
Joystick button
Horn button
High beam button
