The term "Two-Wire" in this context refers to the simplified communication bus used to transmit pump status and control signals between the dispenser electronics and the controller. Unlike five-wire systems (which use discrete relays for every function) or pump-specific proprietary buses (like the Passport or G-Site internal protocols), the Two-Wire Protocol offers a balanced approach: (needed for development): The term "Two-Wire" in this
. While the protocol itself dates back to the late 1980s, its continued use in modern units like the Gilbarco Encore 500 You need a
Because most modern computers use USB or RS-232, you cannot connect directly to the pump's two-wire lines. You need a . (needed for development): The term "Two-Wire" in this
