Download Product Brief

This is the 4-Channel RS485 to RJ45 Ethernet Serial Server. It comes with the standard Computer Network Port (without PoE function). This module supports RS485 independent operation, bi-directional transmission, and Modbus Gateway with MQTT and JSON support. The device has a reliable aluminum alloy casing and comes with a rail mount clip.

The RS485 to ETH (B) IoT gateway is easy to install and has a small form factor. You can use it for different applications such as IoT Gateway, data acquisition, intelligent instrument monitoring, and safety and security IoT, etc.

Transparent Bi-Directional Data Transmission Between ETH and 4-CH RS485

Rail Mount Clip and Wall Mount Support

Easily install in different industrial settings. The device has a robust protective casing made of aluminium alloy.

Modbus Gateway Support

Suitable for Modbus Networking upgrade. You can use it with specific configuration software.

Multiple Communication Modes

Compatible with TCP Server, UDP Multicast, TCP Client, and UDP Mode. Each of the 4 RS485 channels supports these functions separately.

MQTT/JSON to Modbus

When utilized as an MQTT gateway, these devices facilitate the transmission of serial data to an MQTT server using the MQTT protocol in a transparent manner. Compatible servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, among others. The incoming Modbus RTU or non-standard serial data undergo parsing into JSON format and are then encapsulated into MQTT data packets for transmission to the server.

In the role of a JSON data acquisition gateway, the devices establish connections with data acquisition instruments via RS485 interfaces. Subsequently, they autonomously retrieve data, convert it into JSON format, and proceed to transmit it to the designated server. Supported data types encompass Modbus RTU 645 instrument versions 97 and 07, as well as various non-standard RS485 protocols. Configuration of the data format for transmission can be adjusted via the host, with options for transmission protocols including MQTT, HTTP POST, HTTP GET, and others.

Multi Hosts Roll-Polling

Identifies different network devices and responds respective. No crosstalk during the communication with multiple network devices.

User-Defined Registration/Heartbeat Packet

Suitable for device identification and Cloud communication.

NTP Protocol Support

Getting Network Time Information for Data Upload and Serial Output.

Multi Configuration Methods

Supports Web Browser Configuration, DNS Protocol Connected Domain Server Address, and Obtaining Dynamic IP via DHCP.

Multi-Protection

Equipped with onboard power supply and signal isolation, this system delivers a consistent isolation voltage characterized by robust reliability and remarkable resistance to interference. Its integrated TVS (transient voltage suppression tube) effectively mitigates surge voltage and transient peak voltage within the circuit, thereby providing lightning-proofing and ESD protection. Additionally, featuring built-in resettable fuses and protection diodes, it guarantees stable current and voltage output, averting instances of over-current and over-voltage while enhancing shock-proof performance.

Aluminium Alloy Case

Robust protective case made of aluminium alloy with anodic oxidation and sand blasting.

Interface Introduction

Batch Customisation Support

Supports Hardware and Software customosation including LOGO, hardware interface, web page, case, and label.
