Primary Function
Bi-Directional Transparent Data Transmission Between RS485 And Ethernet.
Rail-Mount Support
Easy to combine multiple rail-mounted serial servers together for greater flexibility.
Modbus Gateway Support
Suitable for Modbus grid upgrade, usable with 3D configuration software.
Multi Communication Modes
Supports TCP Server / TCP Client / UDP Mode / UDP Multicast.
MQTT/JSON To Modbus
Flexible conversion between different protocols. As MQTT gateway, serial data can be uploaded to MQTT servers (Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet). JSON data acquisition gateway converts acquired serial data into JSON and posts it via MQTT, HTTP POST or HTTP GET.
Multi Hosts Roll‑Polling Support
Identifies different network devices individually, preventing crosstalk while communicating with multiple network devices.
User-Defined Heartbeat/Registration Packet
Facilitates cloud communication and device identification.
NTP Protocol Support
Provides network time information for serial output or data upload.
Multi Configuration Methods
Supports web browser configuration, dynamic IP via DHCP, DNS protocol connected domain server address.
Package Content & Weight
Weight: 0.077 kg (power supply not included; recommend 12V industrial DIN‑rail power supply).
