Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New Now

Overview — Gilbarco DISpenser Twowire Protocol (for third‑party pump controllers)

features

Here are the key of the Gilbarco Two-Wire Protocol (often referred to as G-Site or TLS-2 over serial) when used with third-party pump controllers for new installations:

1. Single Twisted-Pair Communication

. While the protocol itself dates back to the late 1980s, its continued use in modern units like the Gilbarco Encore 500 This significantly reduces trenching and conduit labor costs

Simplified Retrofitting

For sites upgrading from legacy mechanical dispensers to modern electronics, the Two-Wire Protocol often allows the reuse of existing copper infrastructure. This significantly reduces trenching and conduit labor costs. This significantly reduces trenching and conduit labor costs

Hardware Interface

: Third-party controllers often require an interface converter (e.g., RS-232/RS-485 to Two-Wire) to bridge the gap between standard PC signals and the dispenser's current loop. 2. Communication Parameters This significantly reduces trenching and conduit labor costs

Current Regulation

: Gilbarco dispensers and CRIND devices typically operate on a 45mA loop, while some non-Gilbarco units may use 30mA.
