Three Different Interfaces

Built-in RS232, RS485, and RS422 interfaces — for broader application scenarios.

Ethernet → RS232/485/422

The Ethernet port can simultaneously send data to all three serial ports.

Ethernet to RS232/485/422
RS232/485/422 → Ethernet

Only one of the RS232, RS485, or RS422 ports can simultaneously send data to the Ethernet port.

RS232/485/422 to Ethernet

Multiple Power Supply Methods

  • Power via PoE Ethernet port* — supports IEEE 802.3af standard
  • Power via screw terminal or DC connector: 6–36 V DC, wide voltage range
Power supply methods

* PoE function is only available in the PoE-enabled version.

DIN Rail Mounting

Conveniently combine multiple serial servers on a rail — flexible and effortless.

Modbus Gateway Support

Suitable for Modbus network upgrades. Can be used with specialized software for configuration.

Modbus Gateway

Multiple Communication Modes

Supports TCP Server, TCP Client, UDP, and UDP Multicast.

MQTT/JSON ↔ Modbus

Flexible conversion between different protocols.

MQTT/JSON to Modbus

When used as an MQTT gateway, the device can transmit serial data to an MQTT server via transparent transmission using the MQTT protocol. Servers supported include: Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, etc. Collected Modbus RTU data or non-standard serial data can be parsed into JSON format and packed into an MQTT packet for upload.

When used as a JSON data acquisition gateway, the device connects to measuring instruments via RS485, automatically collects data, converts it to JSON format, and sends it to the server. Modbus RTU protocols, 645 instruments (version 97 and version 07), as well as various non-standard RS485 protocols are supported. The upload format is configured via the host; the JSON upload protocol can be MQTT, HTTP POST, or HTTP GET.

Support for Multiple Host Polling

Different network devices are identified and responded to separately — without cross-interference when working with multiple network devices.

Multiple host polling

Customizable Heartbeat / Registration Packet

Simplifies cloud communication and device identification.

Heartbeat and registration packet

NTP Protocol Support

Obtain network time for output via serial port or data upload.

NTP Support

Multiple Configuration Methods

  • Configuration via web browser
  • Obtain dynamic IP address via DHCP
  • Connect to domain server via DNS protocol
Configuration methods

Multi-level Protection — Reliable and Stable

Built-in power and signal isolation ensures stable isolation voltage with high reliability and interference immunity. Built-in TVS (Transient Voltage Suppressor) effectively suppresses surge and transient peak voltages in the circuit — protection against lightning and ESD. Built-in self-recovery fuse and protective diode provide stable current and voltage output, overload and overvoltage protection, increased shock resistance.
