Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New -
The site controller typically acts as the "active" unit, providing the current for the loop. Communication Parameters
The Gilbarco dispenser two-wire protocol is based on a master-slave architecture, with the pump controller acting as the master and the dispenser as the slave. The protocol uses a simple, ASCII-based command structure, allowing for easy implementation and debugging. The site controller typically acts as the "active"
For implementing or troubleshooting a third-party pump controller using the , you will need to reference specific technical manuals that detail the hardware electrical specifications and the logical command set. 1. Primary Protocol Documentation then throttle EV chargers accordingly.

Hybrid sites with EV chargers need to share transformer loads. A third-party energy management controller can monitor Gilbarco dispenser pulser data over two-wire to calculate power draw from submersible pumps, then throttle EV chargers accordingly.
