: Each pump is assigned a unique ID (typically 1–16). The master polls each address; only the addressed unit responds.
The real "new" breakthrough is hardware. Companies like , Dover Fueling Solutions (Wayne) , and specialized OEMs (such as Tominaga in Japan or EASI in the US) have released next-gen protocol converters. These devices sit between your third-party pump controller and the Gilbarco two-wire loop, performing real-time translation from standard ASCII commands (e.g., "Pump 3, preset 20 liters") into the exact bit-banging current loop required by Gilbarco. : Each pump is assigned a unique ID (typically 1–16)
Essential for understanding the line-level electrical requirements, such as voltage levels and current loop tolerances. 2. Physical Connection & Interface Converters Companies like , Dover Fueling Solutions (Wayne) ,
To integrate a third-party controller, the system must handle both the physical signal conversion and the software logic: Dover Fueling Solutions (Wayne)
