Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New [cracked] -

⚠️ The third-party controller must have an active 20mA current loop interface . If your controller only provides RS-232, you must install an isolated 20mA converter (e.g., B&B Electronics 232LPTTL or equivalent).

| Parameter | Value | |-----------|-------| | Loop voltage open | 12–24V DC (dispenser provides) | | Loop current low | 0–4 mA (logic 0) | | Loop current high | 18–30 mA (logic 1) | | Baud rate | 1200 bps (typical), some older are 600 bps | | Data format | 1 start bit, 7 data bits, 1 parity (even), 1 stop bit | | Character framing | Asynchronous, half-duplex | | Max distance | 2000 ft (600 m) with shielded twisted pair | ⚠️ The third-party controller must have an active
