Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New Guide

The site controller or third-party pump controller typically acts as the Active device (supplying the loop current source), while the fuel dispenser behaves as the Passive node (modulating the current loop via optocouplers).

Immediately kills the current loop transmission or sends a specific termination command to close all fuel valves instantly. The site controller or third-party pump controller typically

Use an oscilloscope to verify that the current-to-voltage conversion produces clean square waves with minimal rise and fall time distortion. 5787 bit/sec (Corporate baud rate), 8 Data bits,

Several cloud-based controllers (e.g., PDI’s FueLink, Kalibrate Edge) now offer two-wire via an IoT gateway that uses an on-board current-loop interface.
