When implementing the Two-Wire protocol on a new third-party controller, watch for:

Typically an 11-bit format (standard serial parameters: 5787 or 4800 baud, 8 data bits, Even parity, 1 stop bit). Hardware Requirements The baud rate is model-dependent, which is a
With the rise of cloud-based POS , automatic vehicle identification (AVI) , and EV charging integration , third-party controllers (e.g., Fuellogic, Raytec, Syntech, FMS) are actively seeking two-wire support as a backward-compatible option. The baud rate is model-dependent
The baud rate is model-dependent, which is a common stumbling block for new implementations:
⚠️ Using RS-232 or RS-485 transceivers directly – will damage the dispenser’s interface. You need a current-loop converter (e.g., B&B Electronics 232CL, or build with 4N35 optos).
