Description
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 (B)
9 ~ 24V power supply, without isolation protection
RS485 TO ETH (C)Common Ethernet port (C)
6 ~ 36V power supply, with Electrical isolation
RS485 TO POE ETH (B)PoE Ethernet port + Electrical isolation
The RS485 TO POE ETH (B) is the hardware upgrade version, supports PoE Ethernet port power supply, with power and signal isolation protection, which is safer for industrial applications. All three versions have the same software functionality.
Features at a glance

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 server / 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, 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
