Details

Industrial serial server, RS485 to RJ45 Ethernet, TCP/IP to serial, rail-mount support, with POE function(optional)
RS485 to RJ45 Ethernet Module

Rail-mount RS485 serial server

Version Options

RS485 TO ETH (B)
Common Ethernet port

RS485 TO POE ETH (B)
PoE Ethernet port + Electrical isolation

These two versions are the same in software functions, while RS485 TO POE ETH (B) is the hardware upgrade version, support PoE Ethernet port power supply, with power and signal isolation protection, which is safer for industrial applications.


Features at a glance

This is an RS485 device data acquisitor / IoT gateway designed for the industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc. The module features RS485 and Ethernet port(POE function is optional), uses screw terminals for power input. Rail-mount case design, small in size, easy to install. 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

Rail-mount support

easy to combine multi rail-mounted serial server together, more freely

Modbus gateway support

suitable for Modbus gridding upgrade, can be used with 3D configuration software

Multi communication modes

supports TCP server / TCP client / UDP mode / UDP multicast

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
