We are pleased to introduce Sollae’s range of industrial Modbus gateways and Serial to Ethernet converters, designed to make industrial integration easy and reliable through standard Modbus RTU and Modbus TCP protocols.
Whether you work with energy monitoring units, data loggers, or industrial automation systems, these solutions help you connect legacy serial devices with modern Ethernet networks — quickly and efficiently.
What do Sollae industrial converters offer?
Sollae products include industrial Modbus gateways that bridge serial interfaces (RS-232, RS-422, RS-485 to Ethernet) with local area networks. This allows traditional Modbus RTU devices to communicate over Ethernet using Modbus TCP, and vice versa.
For example, models like the SMG-5410 Modbus gateway effectively convert Modbus RTU to Modbus TCP.

This makes it possible to combine existing serial-based hardware with modern IP infrastructure without the high cost of replacing your entire system.
How do Modbus RTU and Modbus TCP work?
Modbus RTU is the serial version of the protocol (using RS-485 or RS-232). It sends data in compact binary frames with CRC error checking, making it ideal for robust and noise-resistant industrial environments.
Modbus TCP is the Ethernet-based version. It encapsulates Modbus messages in TCP/IP packets (with an MBAP header) and relies on network-level error control. It is perfect for networked systems, Modbus RTU over TCP/IP, and scalable architectures.
Why choose Sollae Serial to Ethernet gateways?
- ✅ Compatibility & scalability – Achieve legacy serial device integration by connecting Modbus RTU equipment to Modbus TCP networks using Sollae’s reliable gateways.
- ✅ Flexibility – Integrate a wide range of energy meters, factory sensors, and controllers through a single standardized communication protocol.
- ✅ Cost-effective modernization – Upgrade to Ethernet without replacing your existing industrial RS485 devices.
- ✅ Easy setup – Sollae devices offer simple web-based configuration, diagnostics, and monitoring for your IoT gateway.
- ✅ Industry standard – Modbus is one of the most widely adopted protocols in industrial communication, with extensive documentation and tool support.

Basic skills for Modbus Gateway setup
Working with a Sollae Modbus TCP gateway is straightforward, but it helps to have some basic knowledge of:
- Serial communication (RS-232/485 wiring), addressing, and baud rate configuration.
- Network setup (IP addressing, switches, subnetting).
- Understanding of Modbus structure (Master/Client and Slave/Server concepts).
- Basic troubleshooting with Modbus test tools or terminal software.
- Network security awareness when operating Ethernet-based devices.
These skills ensure you can connect, configure, and monitor devices efficiently in both local and remote environments.
