The forecourt controller must act as the current loop master, providing the stable 45mA current. As modern service stations transition toward hybrid fueling
The is the undisputed global benchmark for retail fueling communication, linking forecourt controllers, Point-of-Sale (POS) systems, and fuel dispensers into a singular, synchronized data stream . As modern service stations transition toward hybrid fueling options, IoT telemetry, and multi-vendor hardware configurations, the demand for third-party pump controllers capable of natively decoding this proprietary architecture has skyrocketed. device diagnostics over a two‑wire physical link
The Gilbarco TwoWire (also called Two‑Wire Multiplex or TW) protocol is a low‑level serial communication protocol used between a dispenser controller (pump head) and a point‑of‑sale / site controller or third‑party pump controller. It carries commands and status for fuel selection, nozzle status, dispenser electronics, price/volume totals, authorizations, and misc. device diagnostics over a two‑wire physical link.
For retrofitting older Gilbarco sites (Encore 300/500) without replacing dispensers, the new two-wire protocol converters are the only economical path.
The protocol utilizes a current loop interface, typically operating as a multi-drop serial communication link. It uses an 11-bit data format.
