To successfully integrate a third-party controller, the following physical and logical parameters are standard:
The protocol follows a architecture. The pump controller (Master) initiates all communication by polling the dispensers (Slaves). Every unit on the loop receives the data, but only the specific unit addressed responds, while others ignore the message. Interface Requirements for Third-Party Systems To successfully integrate a third-party controller
For newer installations, Gilbarco has introduced high-speed communication technologies like the Invenco Link and 1 Stop bit.
Connecting a standard PC or a modern PLC to a Gilbarco dispenser often requires an interface converter to bridge the gap between RS-232/USB/RS-485 and the 2-wire current loop. To successfully integrate a third-party controller
Typically 5787 bps , though some configurations may use 4800 bps. Data Format: 8 Data bits, Even Parity , and 1 Stop bit.
