For newer installations, Gilbarco has introduced high-speed communication technologies like the Invenco Link
The protocol follows a architecture. The pump controller (Master) initiates all communication by polling the dispensers (Slaves). Every unit on the loop receives the data, but only the specific unit addressed responds, while others ignore the message. Interface Requirements for Third-Party Systems traditionally at 45 mA
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 For newer installations
To successfully integrate a third-party controller, the following physical and logical parameters are standard: while others ignore the message.
