The J119026 RS485 to 4G Converter is a reliable communication gateway designed to upgrade traditional RS485 devices into remote monitoring systems.
By converting RS485 communication to 4G wireless communication, it allows users to remotely read data, configure parameters, and manage RS485 energy meters through a cloud platform or central monitoring system.
Supporting connection with up to 128 RS485 devices, this converter provides an efficient and cost-effective solution for smart meter projects, industrial monitoring systems, energy management applications, and other scenarios where long-distance wireless communication is required.
Upgrade Existing RS485 Devices with 4G Remote Communication
Many existing energy meters and industrial devices use RS485 communication because of its stability, long-distance transmission capability, and compatibility with Modbus-based systems. However, traditional RS485 devices usually require local data collection through wired connections, which makes remote monitoring and management difficult.
The J119026 RS485 to 4G Converter provides an easy solution to transform existing RS485 devices into remotely accessible systems. By connecting RS485 devices on the lower side and communicating with a remote server, cloud platform, or monitoring software through 4G networks, users can achieve centralized data collection and remote device management without replacing existing meters.
This makes it an ideal choice for upgrading installed RS485 energy meters and other industrial devices while reducing system replacement costs.
RS485 to 4G Communication Gateway for Multiple Devices
The J119026 works as a communication bridge between RS485 devices and 4G networks. The downstream side uses RS485 communication to connect with energy meters or other compatible equipment, while the upstream side uses 4G communication to transmit data to a monitoring platform or server.
One converter can support communication with up to 128 RS485 devices, making it suitable for applications with multiple meters installed in commercial buildings, factories, charging stations, photovoltaic systems, and energy management projects.
The device supports flexible RS485 communication parameters, including baud rates from 4800bps to 115200bps. The default communication setting is 115200/NONE/8/1, while users can configure parameters according to different project requirements.
Compatible with Various RS485 Energy Meters and Devices
The J119026 is designed with wide compatibility. In theory, any RS485 device can be connected through this converter, without being limited to specific meter models or manufacturers.
It can work with various RS485-based devices, especially smart energy meters using Modbus communication protocols. This flexibility allows system integrators and project developers to build customized remote monitoring solutions without changing existing equipment.
Whether upgrading old RS485 electricity meters, integrating industrial instruments, or building a centralized energy monitoring system, the RS485 to 4G converter provides a practical communication solution.
Remote Data Reading and Device Management
Through the 4G network, users can remotely access RS485 device information from a central monitoring system or cloud platform. The downstream RS485 devices are read through an active polling method, allowing the system to collect required data according to project requirements.
The converter can also read and configure its own communication information, including MODBUS ID, device address, and RS485 communication parameters. Server IP address, port, and domain name settings can be configured through the RS485 interface, making installation and maintenance more convenient.
Stable 4G Communication with Flexible Reporting Settings
The J119026 supports scheduled 4G data reporting and heartbeat communication. The default reporting interval is 180 seconds, while the heartbeat interval can be adjusted from 30 seconds to 3600 seconds according to application requirements.
Flexible communication settings allow users to balance between real-time monitoring needs and network data consumption, making it suitable for different types of remote monitoring projects.
Remote Firmware Upgrade for Easy Maintenance
For long-term operation and system upgrades, the J119026 supports remote firmware updates. When new functions or improvements are added, the device can be upgraded remotely without removing the converter from the installation site.
This feature significantly reduces maintenance costs, especially for large-scale deployments where hundreds or thousands of devices may be installed in different locations.
Typical Applications
The RS485 to 4G Converter can be widely used in applications requiring remote access to RS485 devices, including:
Smart energy monitoring systems, commercial building energy management, industrial automation, photovoltaic monitoring systems, EV charging infrastructure, power distribution monitoring, and remote meter reading projects.
For existing RS485 energy meters that need cloud connectivity, the J119026 provides a simple way to add wireless communication capability without replacing the installed meters.
