  • Pump and customer access terminal interface computer converter to convert traditional pump and customer access terminal protocols to high speed ethernet protocols
    Patent number: 6360138
    Abstract: 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.
