SOLEXY BXF3S0101N0018 Industrial Communication Gateway
The SOLEXY BXF3S0101N0018 is a compact industrial communication gateway designed to bridge serial devices (RS‑232, RS‑485) to Ethernet networks. This module enables legacy equipment such as PLCs, drives, and instrumentation to communicate over TCP/IP, integrating them into modern IIoT (Industrial Internet of Things) infrastructures. It supports multiple protocols, including Modbus RTU/ASCII and Modbus TCP, with transparent data conversion.
The gateway features a rugged metal housing for DIN‑rail mounting, with an operating temperature range suitable for factory environments. It includes a web‑based configuration interface for easy setup of network parameters, serial settings, and data mapping. The device also supports firmware updates via Ethernet, ensuring future‑proof functionality.

Key Features
Modbus gateway function: Converts Modbus RTU/ASCII to Modbus TCP, allowing SCADA systems to poll serial devices over Ethernet.
Virtual serial port (VSP): The gateway can emulate a COM port on a PC, simplifying legacy software integration.
Diagnostic LEDs: Power, Ethernet link, serial data activity, and error LEDs for quick status checks.
Security: Access control via IP filtering and password protection.
Data buffering: Stores up to 4 KB of data to prevent loss during network interruptions.
Typical Applications
Retrofitting older machines: Connecting legacy PLCs and drives to a plant‑wide Ethernet network.
Data acquisition: Collecting data from serial instruments and sending to cloud or SQL databases.
Remote monitoring: Enabling remote access to serial devices via the internet.
Building automation: Integrating Modbus RTU HVAC controllers into IP‑based building management systems.
Installation and Configuration
Mount the gateway on a DIN rail. Connect the serial device to the appropriate port (RS‑232 or RS‑485) using a shielded cable. Connect the Ethernet port to the network switch. Apply 24 V DC power. Open a web browser and enter the default IP address to access the configuration pages. Set the serial parameters (baud, parity, etc.), assign an IP address, and define the Modbus mapping. The gateway can be set to act as a Modbus TCP server or client. After configuration, the gateway automatically starts data conversion.
Compliance and Environment
This gateway complies with EN 61000‑6‑2 and EN 61000‑6‑4, carries CE marking, and is RoHS compliant. It is rated for pollution degree 2.
Conclusion
The SOLEXY BXF3S0101N0018 provides a simple, reliable, and cost‑effective solution for bridging serial industrial devices to Ethernet networks, enabling modern integration and remote access.
