Basic Function
Bidirectional transparent data transmission between 4-CH RS485 and Ethernet
Multiple Power Supply Options
Supports PoE network port power supply*, IEEE 802.3af PoE compliant
Supports screw terminal power supply, wide voltage input DC 6–45V
* This feature is only available for the PoE version
Industrial Serial System
Industrial DIN-rail design, supports wall-mount and DIN-rail mount, compact size, easy to install, cost-effective
Modbus Gateway Support
Suitable for Modbus network upgrade, can be used with corresponding configuration software
Multiple Communication Modes
Supports TCP server / TCP client / UDP multicast / UDP modes
Note: This module has 4 channels, each channel supports the above functions independently
MQTT/JSON to Modbus
More flexible conversion between different protocols
When used as an MQTT gateway, devices can upload serial data to the MQTT server via MQTT protocol through transparent transmission. Supported servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, etc. The received Modbus RTU data or non-standard serial data can be parsed in JSON format and packed into an MQTT data packet for uploading.
When used as a JSON data acquisition gateway, devices can be connected to data acquisition instruments via RS485 connection, then automatically acquire data, convert the data into JSON format, and finally send it to the server. The acquired data supports Modbus RTU 645 version 97 instruments, 645 version 07 instruments, as well as various non-standard RS485 protocols. The uploaded data format can be configured via the host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol, etc.
Multiple Host Polling Support
Different network devices will be identified and responded to separately,
no more cross-talk problems when communicating with multiple network devices
Custom Heartbeat/Registration Packet
Easy for cloud communication and device identification
NTP Protocol Support
Obtain network time information for serial output or data upload
Multiple Configuration Methods
Supports web browser configuration, obtains dynamic IP via DHCP,
DNS protocol to connect to the domain server address
Multiple Protections, Safe & Stable Operation
Built-in power isolation and signal isolation, can provide stable isolated voltage with high reliability and strong anti-interference. Built-in TVS (Transient Voltage Suppressor) tube can effectively suppress surge voltage and transient peak voltage in the circuit, lightningproof and ESD proof. Built-in resettable fuse and protection diode to ensure stable current and voltage output, prevent overcurrent and overvoltage, improve shock resistance performance
