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.
