Product overview

NE2-D11E，NE2-D12E single-port serial server enables bidirectional, transparent data transmission from an RS485 serial port to an Ethernet port. It features multiple Modbus gateway modes and MQTTC/HTTPC IoT gateway modes, enabling networking of various serial devices and PLCs. Adopting industrial-grade design standards, it ensures device reliability. The serial server transparently transmits serial data to Ethernet TCP/IP packets, eliminating the need for users to worry about specific details as protocol conversion is performed internally. It is coated with conformal coating, offering anti-mold, anti-humidity, and anti-salt spray properties.

RS485 to Ethernet serial server

Core Functions: Transparent Transmission and Multi-Protocol Support

The core advantage of the NE2 series serial server lies in bidirectional transparent transmission between serial port and Ethernet—users do not need to focus on underlying protocol details, as the device automatically converts serial data and TCP/IP data packets to ensure efficient and stable data flow. Additionally, the product supports rich network protocols and interface modes:

  • Network Interface: Equipped with an RJ45 10/100M adaptive Ethernet port, supporting automatic recognition of crossover/straight-through cables for flexible deployment.

  • Multi-Protocol Compatibility: Supports 2-channel Socket modes such as TCP Server/Client, UDP Server/Client, HTTPC, and MQTTC. The single-channel server mode can simultaneously connect up to 5 connections, meeting the needs of multi-device concurrent communication.

  • Modbus and IoT Gateway: Built-in multiple Modbus gateway modes (e.g., multi-host mode, active upload mode) and supports quick access to mainstream IoT platforms such as Alibaba Cloud, Baidu Cloud, OneNET, and Huawei Cloud, compatible with MQTT 3.1.1 standard protocol, making it easy to build industrial IoT systems.

Industrial-Grade Design: Stable and Reliable for Complex Environments

The NE2 series strictly follows industrial-grade standards to ensure long-term stable operation under harsh working conditions:

  • Wide Voltage and Isolation Protection: Supports 2.7~5.5V power supply, with some models featuring dual isolation design for power and signals, effectively resisting electromagnetic interference and ensuring secure data transmission.

  • Wide Temperature Range: Industrial-grade temperature tolerance from -40℃ to +85℃, suitable for complex environments such as factories and outdoor sites.

  • High Reliability Mechanisms: Built-in watchdog, disconnection reconnection, timeout restart, Keepalive detection, and other functions, combined with heartbeat and registration packet mechanisms, enabling quick recovery from abnormal connections and reducing manual maintenance costs.

Flexible Configuration and Expansion: Adapting to Diverse Needs

The product offers three convenient configuration methods (configuration tool, web page, AT commands), allowing users to choose flexibly based on scenarios. It supports DHCP for automatic IP acquisition, DNS domain name resolution, and virtual serial port functions, simplifying network deployment. Furthermore, some models support:

  • Multi-Serial Protocols: Compatible with RS485/232/422/TTL and other serial standards, adapting to different device interface requirements.

  • POE Power Supply: Integrates data and power transmission via network cables, reducing wiring complexity, especially suitable for remote device installation.

  • Customizable Functions: Supports custom short connection intervals, online upgrades, and one-click factory reset, meeting personalized debugging and maintenance needs.

Wide Application Scenarios

The NE2 series serial server can be seamlessly integrated into various industrial and IoT scenarios, such as:

  • Industrial Automation: Enabling remote monitoring and data collection of PLCs, sensors, and numerical control equipment.

  • Smart Buildings: Supporting networked management of access control systems and environmental monitoring devices.

  • Energy and Municipal Services: Applied in remote meter reading (AMI) systems for smart electricity and water meters.

  • Medical and Security: Facilitating data upload for medical devices and network access for security alarm systems.

The NE2 series single serial server, centered on "simple deployment, stable transmission, and flexible expansion," breaks down the network barriers of traditional serial devices through transparent transmission technology and multi-protocol support, providing a cost-effective networking solution for industrial digital transformation. Whether for equipment upgrades in small and medium-sized enterprises or intelligent upgrades in large industrial systems, the NE2 series can be a reliable choice for users, driving dual improvements in device networking efficiency and management levels.
