Reducing the Pain at the Pump
The data communications protocols used for communications between gas pumps, credit card readers, key pads and the controlling computer have never been standardized. One company’s gas stations used a current loop circuit to measure how much gas was dispensed and RS-485 for communications with credit card readers and the keypads. They wanted to convert all of this data to Ethernet for use by the local controlling computers as well as the company’s larger network.
B+B designed and built a custom solution that solved the problem in a single device. Designated the ESP906CL, it converts both current loop and serial data to Ethernet before transmitting it to the controlling computer. It has reduced the need for maintenance at all of the customer’s locations while simultaneously making their data flow more smoothly.
