Industrial serial server, RS485 to RJ45 Ethernet, TCP/IP to serial, rail-mount support
Rail-mount RS485 serial server
This is a RS485 device data acquisitor / IoT gateway designed for 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 ports, uses screw terminals for power input, supports 9~24V wide range power supply. Rail-mount flame-retardant 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.

Bi-directional transparent data transmission between RS485 and Ethernet
Easy to combine multi rail-mounted serial server together, more freely
Suitable for Modbus gridding upgrade, can be used with 3D configuration software
Multi communication modes
supports TCP server / TCP client / UDP mode / UDP multicast
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 MQTT data 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
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
