Gilbarco Veeder-Root continues to innovate. The introduction of the enables remote dispenser management. This next-generation pump control node allows retailers to perform remote software updates and changes through cloud-based platforms. The Hub cloud-based solution provides real-time connectivity and open APIs, empowering device control and optimization with a simple, consistent customer experience for streamlined c-store management. The trend toward connectivity is also seen in the integration of modern payment technologies, such as FlexPay Connect , which leverages existing two-wire infrastructure to set up high-speed connections for chip card capabilities on the forecourt, avoiding costly new conduit installation. The open nature of the Two-Wire Protocol has
A standard Gilbarco data packet relies on ASCII control characters to anchor transmission frames and ensure data integrity. General Frame Format Description ASCII Hex Value Start of Header or Start of Text 0x01 or 0x02 Address Target fueling position ID Variable (e.g., 0x31 for Pump 1) Command / Data Action code and associated parameters Variable ASCII strings ETX End of Text 0x03 LRC Longitudinal Redundancy Check (Checksum) Calculated byte Calculating the LRC
5. Challenges and Best Practices for Third-Party Engineering This next-generation pump control node allows retailers to
For decades, the fuel retail industry has operated in a state of semi-walled gardens. Major dispenser manufacturers, particularly Gilbarco Veeder-Root, developed proprietary communication protocols that made it notoriously difficult for third-party point-of-sale (POS) systems, fleet fueling managers, and automated tank gauge (ATG) integrators to communicate directly with the dispenser’s hydraulic components.
The converter then translates this into the two-wire current loop pulse train. Within 50ms, the Gilbarco dispenser activates the relay for that hose. A standard Gilbarco data packet relies on ASCII
For fuel retailers, integrating third-party systems with forecourt equipment can often feel like navigating a maze of proprietary barriers. However, the stands as one of the most enduring solutions for enabling third-party control over fuel dispensers. Officially named the "Gilbarco Dispenser Two-Wire Protocol for Third-Party Pump Controllers," this technology has served as a bridge between open innovation and proven hardware for decades, and it continues to evolve to meet the demands of modern fueling stations.
