Onboard equipment (OE) — Telematics system elements, directly installed in Vehicle.
Parameter — time-varying or space characteristic of the Vehicle (SPN value). For example,
speed, fuel volume in the tank, hourly fuel consumption, coordinates. Parameter is usually
displayed in the form of graph, or averaged data.
Counter — cumulative numerical characteristics of Parameter. Counter is represented by a
number, which can only grow in time. Examples of Counters: fuel consumption, engine
operation time, total distance and other.
Telematics system — complex solution for vehicle monitoring in real time and trip analysis.
The main monitored characteristics of the vehicle: Route, Fuel consumption, Working time,
technical integrity, Safety. In includes On-board report, Communication channels,
Telematics service

Telematics terminal (Tracking device, Telematics unit) is a unit of Telematics system used
for reading the signals of Vehicle standard and additional sensors, getting location data and
transmitting the data to the Server.
Vehicle an object controlled within Telematics system. Usually Vehicle means a truck,
tractor or bus, sometimes a locomotive or river boat. From Telematics system point of view,
stationary objects are also considered to be vehicles: diesel gensets, stationary tanks,
boilers/burners.
Function module (FM) unit-embedded component of hardware and software combination,
executing a group of special functions. Uses input/output PGNs and settings PGNs.
Unit is an element of vehicle on-board equipment compatible with S6 bus, which uses
S6 Technology.
