Figure ‎1-5. Wireless Gateway Terminal (WGT)
The units that provide data to the WGT are:
 DataPass - DataPass is a miniature unit that connects to the vehicle bus and captures data
from the vehicle CPU/BUS. It then transmits this data to the nearest Wireless Gateway
Terminal (WGT) in the forecourt.
 FuelOpass - FuelOpass is a passive vehicle identification tag for refueling. Its encrypted
data includes the account to be charged and is read by the Nozzle Reader device using RFID
contactless technology.
 VIU - VIU is an active Vehicle Identification Unit for refueling. The data includes odometer
and engine hour meter.
 Nozzle Reader (NR) - Nozzle Reader is a self contained unit installed on the nozzle which
reads the FuelOpass data using contactless technology.
To obtain maximal grid availability, several WGT units can be installed to create a robust 'mesh'
network.

Safety Barriers are required in the truck whenever the Fuel Truck Controller includes an uVIT.
uVIT is electrically connected to the transceiver coil of the nozzle. This coil is intended for use in
potentially explosive atmosphere. Therefore the connection between these devices must be done
via an intrinsically safe barrier. Consequently, the truck must be equipped with an external Barriers
Box. The barriers in use depend on the geographical location of the installation:
 Barriers and nozzle rings must be installed on dispensers as UL Listed by Report Retrofit
kits prior to the installation of the Fuel Truck Controller.
 P/N 808012500 Barrier4 (Atex – For all regions except North America)
