For new third-party pump controllers needing basic compatibility with Gilbarco dispensers, the remains a viable, simple, and deterministic interface. However, it is strongly recommended to evaluate whether the dispenser fleet supports Gilbarco’s current Ethernet/IDT (Intelligent Dispenser Terminal) protocol, which offers richer data and better diagnostics.
Unlike pure relay-based systems, the Two-Wire Protocol allows the controller to detect specific states (running vs. stopped) and volume delivery in real-time, enabling better inventory management and leak detection monitoring. the remains a viable
