Gilbarco proprietary systems send a "Resettle" command every 60 seconds to clear hanging transactions. Third-party controllers often forget this. By promoting interoperability

The Gilbarco dispenser two-wire protocol represents a major breakthrough in fuel retailing technology, enabling seamless communication between Gilbarco dispensers and third-party pump controllers.
