Primary Function

Bi-Directional Transparent Data Transmission Between RS232/485/422 And Ethernet

Three Different Interfaces

Onboard RS232 / 485 / 422 Interfaces, Suitable For More Application Scenarios

Ethernet Port To RS232/485/422

The Ethernet Port Can Send Data To Three Serial Ports At The Same Time

RS232 / 485 / 422 To Ethernet Port

Only One Of The RS232, RS485, And RS422 Can Send Data To The Ethernet Port At The Same Time

Three Methods For Power Supply

Support PoE Ethernet Port Power Supply, Suitable For IEEE 802.3af PoE Standard
Support Screw Terminal And DC Power Port For Power Supply, DC 6~36V Wide Voltage Range Input

Rail-Mount Support

Easy To Combine Multi Rail-Mounted Serial Server Together, More Freely

Modbus Gateway Support

Suitable For Modbus Networking Upgrade, Can Be Used With Specific 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 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 resistance
