The application of German conextop’s serial port to Ethernet module Neport in POS machine

Traditional POS machine consumer systems mostly use RS-232 and 485 serial ports for communication and transmission with computers. In view of the short transmission distance of RS-232 serial communication and the one-to-one characteristics of RS-232 serial communication, in actual application, it must be ensured that each POS machine corresponds to a computer, and the farthest distance of RS485 communication is only 1.5KM. And the longer the communication transmission distance, the slower the transmission rate.

With the expansion of modern shopping malls, supermarkets and hypermarkets, the use of POS machines is increasing. The wiring distance of the entire communication network cannot be satisfied by the traditional 232 and 485 communication. Shopping malls, supermarkets and hypermarkets also have higher and higher requirements for the overall management of POS machines. How to transmit the information of all POS machines to the control center for unified analysis, management and data processing is a major problem faced by the management. Early engineering contractors used multi-serial port cards to collect and transmit data from multiple POS machines to the control center through the multi-serial port cards. However, in practical applications, due to the limited transmission distance of serial communication, the multi-serial card still cannot fully meet the demand.

Use the serial port to TCP/IP network function of Neport, the serial port server module of Germany conextop, to convert the RS-232 and 485 serial ports of the POS machine into a TCP/IP network interface, so that the POS machine can directly connect to the TCP/IP network and carry out data through the network. Centralized collection. So as to ensure the unified management of data.
