Installation Manual

Section 1 Introduction
1.1. General
This manual provides instructions on how to install and configure the nWGT, part of Orpak's Wireless
Forecourt Payment Solution.
1.2. Product Description
nWGT units are installed in the forecourt, typically one per dispenser, and create the forecourt mesh
wireless network that covers the entire station. Each of the forecourt devices (dispensers, OPTs, printers) is
physically connected to the nWGT unit. The unit can be also installed anywhere in the island, on a wall, or
on a pole.
The Wireless Forecourt network is based on mesh network topology uses IEEE 802.15.4 replacing the cable
infrastructure and provides full and robust wireless coverage throughout the station forecourt between
the FCC / POS (through the CnWGT) and the dispensers and other forecourt devices. The wireless network
is encrypted by AES-128 to provide high security for the data over the air.
The CnWGT is the access point to the wireless network from the station office. This unit is typically
connected to the FCC (or POS) using LAN to provide the access between the FCC / POS and the forecourt
devices for authorization and service. The nWGT can be operated as a converter unit, from wireless
network to serial channels, such as RS485 or with an add-on dispenser interface.
1.2.1. Wireless Forecourt
Wire infrastructure at a gas station’s forecourt increases the cost of automating existing stations or
building new ones and the TCO for the oil company and station owners.
Orpak offers a solution for a fully wireless forecourt connecting the controller and the dispensers via
Orpak's highly robust wireless network. The Wireless Forecourt is specially designed for the gas station
environment and uses unlicensed frequency band in mesh configuration with strong redundancy and
encryption.
