4-Ch RS485 To RJ45 Ethernet Serial Server, 4 Channels RS485 Independent Operation, Rail-Mount Industrial Isolated Serial Module, Bi-Directional Transparent Transmission, Modbus Gateway, PoE Function
Features:
This is a multi-functional device data acquisitor / IoT gateway with 4-ch RS485 and an Ethernet port (PoE version optional), small in size, easy to install, and cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring, meeting various application scenarios.
- 4-ch RS485 can work independently without affecting each other at the same time, enabling more effective data transmission
- Combines multiple functions in one, including serial server, Modbus gateway, MQTT gateway, and RS485 to JSON, etc.
- Adopts screw terminal for stable power input
- Wall-mount and rail-mount case design, easy to install, for quick deployment and expansion

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, improve shock proof performance
