| Abstract: | A method of designing low-cost extended board for fiscal cash register is presented, which can connect Intemet through LAN. By using serial port, the board can realize commuication with fiscal cash register and fiscal cash register connects. Intemet with the board. Simplified TCP/IP protocols are implemented by this board so as to communicate with remote sewer. Experiments prove that the board takes advantages of high efficiency, stabilization and cheapness, which has the practicable value to the widely used similar equipments of fiscal cash register. |
