Apparatus and method for interfacing a point-of-sale controller (POS) with a customer access terminal (CAT) of a fuel dispenser by converting traditional communication protocols into high speed ethernet protocols

摘要

A fuel station site architecture includes at least one point-of-sale (POS) controller, at least one new generation fuel dispenser having advanced features, and a site forecourt controller coupled between the POS controller and the fuel dispenser. The site forecourt controller includes a device for interfacing the POS controller with the fuel dispenser by providing a protocol and electrical signal interface between a first protocol and electrical signal requirement of the POS controller and a second protocol and electrical signal requirement of the fuel dispenser, wherein the second protocol and electrical signal requirement include requirements for features which may not be supported by a prescribed POS controller.
