Supports Ethernet Port Cascade and PoE cascade power supply
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
Primary function
bi-directional transparent data transmission between 8-Ch RS485 and Ethernet
Multi Power Supply Options
Supports PoE Ethernet port power supply*, Suitable for IEEE 802.3af PoE standard;
Supports Screw Terminal for Power Supply, DC 7V~36V Wide Voltage Range Input
* This function is only available on the PoE version
Industrial Serial Server
Industrial Rail-mount Design, Support Wall-mount and Rail-mount Installation, Compact Size, Easy Installation, Cost-Effective
Installation Selection
When using rail-mount installation method, you can remove the wall-mount brackets or install them on the back of the case as shown in the picture below; When using wall-mount installation, you need to remove the rail-mount buckle.
Rail-mount Installation
Wall-mount Installation
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 8-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 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
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, improves shock proof performance
