Rail-Mount Serial Server

Industrial Rail-Mount Support, Easy To Install, Compact Size, Cost-Effective

Function Block Diagram

Support Transparent Transmission Mode

Supports TCP Server / TCP Client / UDP Server / UDP Client

Serial Command Mode

The user sends data to the server according to the protocol
Send data to different servers without restarting

Support HTTPD Client Mode

After the user has set the HTTP header through AT commands or web page, the module can send data to the HTTP server, or obtain data from the HTTP server

Support MQTT Function

Devices can subscribe to other MQTT client messages, and can publish topic information to the server. Supports subscription of 6 messages and publication of 6 topics, wider range of use and more applicable scenarios. Users can view device-related information through terminal devices or cloud platforms

Modbus Gateway Support

Support Modbus TCP And Modbus RTU Interconversion Mode

AT Command Mode

The user can query the current status of the module, or set related parameters, by sending AT commands

Features

Multi Configuration Methods
Supports muliti configuration methods such as hosts, Web Browser and serial port Configuration

Socket Distribution Protocol
In the transparent transmission mode, the serial device can send data to the specified Socket link; the network data of each Socket is sent to the serial device through the serial port.

Hardware Protection
ESD Level 4 Static Protection, Level 3 Surge Protection, EFT Level 3 Electrical Fast Transient/Burst Protection.

Customized registration packets, heartbeat packets
The registration package is used to identify the device information to the server, so that the server can identify the device.
