PURPOSE: A site controller is provided to transmit/receive data with each gas station through a serial interface network and transmit/receive the data with a POS(Point-Of-Sale) system through an Ethernet network. CONSTITUTION: A serial module(105) receives a serial device ID from a serial device, sets the connection with the serial device, and receives the serial device data matched with the serial device from the serial device. A data interpreter(103) interprets the received serial device data. An Ethernet module(107) transmits the interpreted serial device data to the POS system(111). A controller(101) generates a serial device control signal matched with the serial device. |
