New Products
2026-06-24

Introduction
The GW-2500iM series is a security gateway designed to seamlessly convert Modbus TCP to Modbus RTU/ASCII. Its built-in web server supports user authentication and HTTPS encrypted communication, protecting web communication and ensuring data security while preventing information leakage. The module supports various industrial IoT communication protocols, including Modbus TCP and UDP. Optional TLS authentication and encryption provide an additional layer of protection, safeguarding valuable data and devices from unauthorized access or tampering during transmission.
Furthermore, the GW-2500iM is equipped with an IP address filtering function. This function enables users to define specific IP addresses that are either allowed or blocked, ensuring comprehensive information security protection.
