Gilbarco Dispenser Two-wire Protocol For Third Party Pump Jun 2026

The is a proprietary communication standard used extensively in the retail petroleum industry to bridge the gap between Point of Sale (POS) systems, forecourt controllers, and fuel dispensers. Developed by Gilbarco Veeder-Root , this protocol governs how data—such as fueling transactions, dispenser status, pricing updates, and authorization limits—is securely transmitted over a standard physical physical layer.

: Used to manage wiring for multiple dispensers and can sometimes multiplex data with other signals. Gilbarco Dispenser Two-wire Protocol For Third Party Pump

Need a custom driver for the Gilbarco two-wire protocol? Consult a certified Gilbarco VAR (Value Added Reseller) before cutting any wires to avoid voiding your UL certification on the forecourt. The is a proprietary communication standard used extensively

Successful third-party integration requires specific wiring to maintain signal integrity and safety: Cable Requirements : Unshielded Twisted Pair ( ) is mandatory; shielded wire must not be used. Wire Gauge (minimum) for runs up to 1,000 feet. (minimum) for runs up to 2,600 feet. Configuration Need a custom driver for the Gilbarco two-wire protocol

While the Two-Wire Protocol is simple in concept, implementing it for a third-party system involves several hurdles:

Standard communication settings vary depending on the dispenser model. Most implementations use a for the physical layer. Highline-2, Euroline, Euro Dimension Highline-111, A.G. Walker Baudrate 4800 bit/sec 5787 bit/sec (Corporate) Databits Parity Stopbits Key Hardware Requirements
