    Wireless serial communication

    With the development of Internet of things technology, all fields of intelligent terminals continue to access a variety of network. In some industries, such as agriculture and forestry, security, intelligent Home Furnishing, remote meter reading, or some of the remote areas of the project, because the network is not developed or wiring is difficult, wireless networking has become the best way of serial terminal equipment such as PLC, instrument and sensor connected network, according to the customer demand and the application prospect, puts forward a comprehensive Kanghai era the wireless serial port server solutions, according to the various advantages of the wireless protocol developed Kanghai era NC900X series wireless serial server.
    Features of NC900X series wireless serial port server
    1, product line rich
    The NC900X wireless serial port server mainly has the wireless zigbee:NC900-Z series, the wireless WiFi:NC900EW series as well as the wireless 3G:NC900EG series.
    2, performance comparison
    NC900-Z products operation of low power consumption, low cost, low communication rate, the communication transmission short delay, suitable for a small amount of data communications, the transmission distance is generally less than 2km, for ad hoc network, network access and high capacity, serial RS-232, the highest rate of up to 115200bps. The wireless serial port server NC900-Z can be configured by a command mode or a console port, and the built-in node detection tool enables the newly added nodes to quickly connect to the network.
    NC900EW products, high communication rate, can achieve 10-100M communication rate, network is simple, can provide a variety of modes, play a routing, AP, terminal, etc.. Transmission distance in 100m or so, suitable for a small range of large data communications. Serial RS-232/422/485 three in one interface, the highest rate of up to BPS 921.6K. The wireless serial server NC900-W via Ethernet or wireless Ethernet port configuration, provide com driver, TCP SERVER, TCP CLIENT, UDP, antithetical couplet mode, reverse terminal mode, through WEP, WPA, WPA2 to establish a safety data communication, built-in WLAN node detection tools etc..
    NC900EG products, communication speed in 2.2-14.4M, fast communication speed, can be connected to any corner of the radio signal, the essence is to use dial-up way to connect to the telecom / Unicom / mobile and other servers, access to Internet resources. Serial RS-232/422/485 three in one interface, the highest rate of up to BPS 460.8K. Wireless serial port server NC900EG can be configured through the Ethernet port to provide CLIENT TCP working mode.
    3, program features
    NC900-Z products, suitable for data communication speed is low, the amount of data is small, the number of terminals and can not be predicted, network uncertainty, communication distance and other field applications. The typical application include: agricultural greenhouses, in agricultural greenhouses, the terminal for the sensor, a small amount of data, various sensors are quantity, wide distribution, not suitable for wiring, in addition the number of sensors will be with the application, location and quantity change, transmission distance, therefore, NC900-Z products can provide solutions good for agriculture and forestry.
    NC900EW products, data communication speed, serial communication and customer support multiple modes, good software compatibility, which is mainly used in industrial plants, general industrial area is relatively small, the plant area of wiring is difficult. But the plant generally has its own wired network or WiFi coverage signal, NC900EW serial server can quickly connect the terminal to the plant network, the realization of the plant in the serial terminal easy networking.
    NC900EG products, data communication speed, transmission distance is not restricted, therefore more suitable for remote areas or is inconvenient, need to remote communication places, typical applications of remote meter reading system, remote meter reading system with time selective communication, the amount of data, the cost is moderate, users can make long-distance communication in need of time.
