Terms and Definitions

Server

— hardware and software combination of Telematics Service ORF 4, designed for

Operation Data processing and storage, also for generation and transfer of Analytical Re-

ports upon User's request.

Event

— relatively rare and sudden change in SPN. For example, the attempt to falsify val-

ues of ―Instant fuel consumption‖ counter by applying electromagnetic field to fuel flow me-

ter will be recognized as ―Interference‖ Event. An Event can have one or several character-

istics. ―Interference‖ Event has the following: date/time and duration of interference. When

the Event occurs, a terminal unit registers the time of occurrence, which is later mentioned

in a report on the event. Thus, the Event is always attached to exact time and place of oc-

currence.

Counter

— cumulative numerical characteristics of Parameter. Counter is represented by a

number, which can only grow in time. Examples of Counters: fuel consumption, engine op-

eration time, total distance and other.

Telematics system

— complex solution for real-time and after trip vehicle monitoring and

control. Main vehicle parameters monitored: route, fuel consumption, operation time, tech-

nical condition of vehicle, safety. Consists of OE, Communication channels, Telematics Ser-

vice ORF 4.

Vehicle

— an object controlled within Telematic system. Usually Vehicle means a truck,

tractor or bus, sometimes a locomotive or river boat. From Telematic 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

— an element of Onboard Equipment of Vehicle, which is connected to Telematics In-

terface S6. Particularly, in this document Unit means DFM fuel flow meter.
