Understanding the Gilbarco Dispenser Two-Wire Protocol The is a proprietary communication standard used to interface Gilbarco fuel dispensers with Point-of-Sale (POS) systems and third-party pump controllers . It operates on a current loop principle, traditionally at 45 mA , although variants like 20 mA or 60 mA may be encountered depending on the specific hardware. Core Technical Specifications
The RS-232 to Two-Wire Converter Box is an essential diagnostic tool and alternative interfacing component. Its primary functions are to:
Integrating a third-party controller with a Gilbarco dispenser typically follows this high-level process: Its primary functions are to: Integrating a third-party
A common stumbling block when developing third-party controllers is matching Gilbarco’s specific data frame requirements. Bit Adjustments and Baud Rates
: Optional data specific to the request (e.g., fuel price configuration, preset amount). fuel price configuration
Open-circuit voltage typically ranges between 24VDC and 30VDC.
*Disclaimer: This document is for informational purposes traditionally at 45 mA
Below is a of this topic, focusing on what’s “new” or relevant for third-party integration in 2024–2026.
