RS485 to WiFi and Ethernet Serial Server – Modbus and MQTT Gateway – Rail Mount Support
Downloads
This RS485 IoT gateway is a data acquisitor designed for industrial use. It facilitates communication between RS485 and WiFi/Ethernet module. It is a multi-function serial server that supports MQTT and Modbus gateways and operates as an RS485 to HTTPD client.
The main functions include serial to Ethernet, Serial to WiFi, and Ethernet to WiFi communication. The power input is received from the screw terminal that supports a 5V ~ 36V power supply.
The housing of the device features the V0 Flame-Retardant material. It is ideal for multiple applications including but not limited to IoT gateway, data acquisition, intelligent instrument monitoring, and IoT security.
Primary Function
Supports RS485 to Ethernet, RS485 to WiFi, and Ethernet to WiFi communication.
Supports Industrial Rail Mount
Function Block Diagram
Transparent Transmission Mode
Supports TCP Client, TCP Server, UDP Client, and UDP Server.
Serial Command Mode
Data transmission to multiple servers without requiring restart. You can send data to the server according to the protocol.
HTTPD Client Mode
Once you use the web page or AT command to set the HTTP header, this module can receive data from and send data to the HTTP server.
MQTT Function
Subscribe to MQTT client messages and publish information to the server. The device supports the publication of 6 topics and subscription of 6 messages enhancing the applicability in different scenarios. You can view information about the device through Cloud platforms or terminal devices.
Modbus Gateway Support
Modbus RTU and Modbus TCP Interconversion Mode.
AT Command Mode
Send AT commands to set related parameters or get the current status of the module.
Multiple Configuration Methods
Configure the device using the web browser, hosts, or serial port.
Socket Distribution Protocol
Send data to specific socket connection on transparent transmission mode. Data and network of each socket connection can be transferred through the serial port to the serial device.
Hardware Protection
Surge Protection LEVEL3, Static Protection ESD LEVEL4, Electrical Fast Transient and Burst Protection EFT LEVEL3
User-Defined Registration Packet
You can use the registration/heartbeat packet to register the device on the server. This way, the server can easily identify the device.
