As a member of the "Xiaoyitong series", the single serial server NE2-D11/NE2-D12 can be used to realize the two-way transparent transmission of data from RS485/RS232 serial port to Ethernet port. It has a variety of Modbus gateway modes and MQTTC/HTTPC IoT gateway modes, which can meet the networking functions of various serial port devices/PLCs, and adopts industrial-grade design standards to ensure the reliability of equipment. The serial port server realizes the transparent transmission of TCP/IP packets from serial port data to Ethernet, and users do not need to care about specific details, and the protocol conversion is completed inside the device.
It comes with RJ45 interface, power supply, RS485/RS232 port, and 2.54mm spring terminals for more convenient wiring.
What is RJ45 interface?
The main application of the RJ45 interface is in the Ethernet environment for data transmission between local area networks (LANs). Whether it is a home, office, or data center, almost all computers, routers, switches, network hubs, servers, and other network equipment will be equipped with RJ45 interfaces.
The NE2-D11/D12 RJ45 supports 10/100M Ethernet interfaces. 4 communication mechanisms, fast configuration to achieve transparent data transmission. The product supports 2-way sockets, each of which supports TCP Server, TCP Client, UDP Server, UDP Client, HTTPC and MQTTC, and 5-way Socket connection in server mode.
It supports the standard MQTT protocol and can quickly access the standard MQTT servers of Alibaba Cloud, Baidu Cloud, OneNET, and HUAWEI CLOUD 3.1.1.
Multiple ModBus gateway modes, including simple protocol conversion, multi-host mode, storage gateway, configurable gateway, and active upload mode, are suitable for more application scenarios.
It can access the Internet and LAN, support HTTP protocol (GET/POST request), save HTTP server resources, and also support virtual serial port software and FOTA remote upgrade.
DNS domain name resolution, you can customize the domain name resolution server. It has a short connection function, and the short connection interval can be customized. All modes support heartbeat packets and registration packets, and link verification can be performed.
Multiple configuration methods, configuration tools, web page configuration, and AT command configuration. IP is automatically assigned, and the router automatically assigns the IP address without the need to manually set the IP address individually.
Serial servers are widely used, covering industrial automation, security monitoring, smart home, retail POS systems, weather monitoring, remote data center management and other industries.
