Features at a glance
This is a 2-ch RS485 device data acquisitor / IoT gateway designed for the industrial environment. Dual RS485 can work simultaneously without interfering with each other. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, and network switch. The module features dual RS485 and dual Ethernet ports (PoE function optional), uses a DC port (outer diameter: 5.5mm, inner diameter: 2.1mm) and screw terminal for power input. The case with rail-mount support, is small in size, easy to install, and cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring...

Primary function
bi-directional transparent data transmission between RS485 and Ethernet
Multi Power Supply Options
Support PoE Ethernet port power supply*, Suitable for IEEE 802.3af PoE standard
Support Screw Terminal and DC Power Port for Power Supply, DC 6~45V
Wide Voltage Range Input
Support Ethernet Port Cascade
Onboard 2-ch Ethernet Ports for communication and cascade
Either one can be used for dual serial server network communication, while the other one can be used for cascading or communication with other devices
* Note: Each module in the cascade needs to be powered individually. The working current of the module is 12V/150mA (MAX) and can be cascaded up to 8.
Rail-mount support
Industrial-grade rail design, compact size, easy installation, cost-effective
Modbus gateway support
suitable for Modbus networking upgrade, Can Be Used With specific Configuration Software
Multi communication modes
supports TCP server / TCP client / UDP multicast / UDP mode
* Note: This module is dual-channel, and each channel supports the above functions separately
MQTT/JSON to Modbus
more flexible conversion between different protocols
When used as MQTT gateway, the devices can upload serial data to MQTT server by MQTT protocol through transparent transmission, supported servers including Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, etc. The acquired Modbus RTU or non-standard serial data can be parsed into JSON format and packaged into MQTTdata packet for uploading.
When used as JSON data acquisition gateway, the devices can be connected to data acquisition instruments through RS485 connection, then acquire data automatically, convert the data into JSON format, and finally post it to server. The acquired data supports Modbus RTU 645 instrument 97 version, 645 instrument 07 version, as well as sorts of non-standard RS485 protocols. The uploaded data format can be configured via host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol, and so on.
Multi hosts roll-polling support
Different network devices will be identified and responsed respectively,
No more crosstalk issue while communicating with multi network devices
User-defined heartbeat/registration packet
Easy for cloud communication and device identification
NTP protocol support
Getting network time info for serial output or data upload
Multi configuration methods
Supports Web browser configuration, obtaining dynamic IP via DHCP,
DNS protocol connected domain server address
Multiple Protection, Safe And Stable
Onboard power supply and signal isolation, it can provide stable isolation voltage with high reliability and strong anti-interference. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable output of current and voltage, prevents over-current and over-voltage proof, improve shock proof performance
