Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New Portable · Easy

Nozzle returned to boot, final transaction data ready for retrieval.

0x03 — Signals the end of the data payload.

: Releasing the pump for a transaction after a user has been verified or a payment pre-authorized. Preset Management Nozzle returned to boot, final transaction data ready

The new third-party controller must correctly interpret the Gilbarco response codes. These codes contain information on: Idle, Authorized, Fueling, Stopped, Finished.

The PPC must be capable of:

The protocol operates with specific serial parameters depending on the dispenser model: Baud Rate Options 5787 bit/sec

Do you need help with the or the hex command structures ? | Parameter | Specification | | :--- |

| Parameter | Specification | | :--- | :--- | | | 20mA Current Loop (not RS-232 voltage levels) | | Topology | Daisy-chain (one pair of wires from controller to dispenser 1, then to dispenser 2, etc.) | | Wire Type | Twisted pair, shielded (Belden 8760 or equivalent) | | Max Distance | 2000 ft (600m) per loop | | Communication | Half-duplex, asynchronous | | Baud Rate | 1200 bps (fixed, non-configurable on most legacy dispensers) | | Data Format | 1 start bit, 7 data bits, even parity, 1 stop bit |

Maximizing Forecourt Efficiency: Integrating the Gilbarco Dispenser Two-Wire Protocol with Third-Party Pump Controllers then to dispenser 2

These controllers often allow easier integration with a wide variety of Point-of-Sale (POS) and Back-Office Systems (BOS).
