TRENDnet TI-M42 4-Port Industrial Modbus Gateway

The TRENDnet TI-M42 is a hardened industrial Modbus gateway designed to bridge legacy serial-based equipment with modern TCP/IP networks. It provides a reliable and cost-effective solution for integrating industrial control systems, sensors, and other operational technology (OT) devices that utilize RS-232, RS-422, or RS-485 communication protocols. Its primary purpose is to enable seamless data exchange between these serial devices and a central network infrastructure, facilitating remote monitoring, management, and data acquisition in demanding environments. Engineered for high reliability, this gateway features a rugged IP30-rated metal housing and can withstand a wide operating temperature range of -40° to 75° C. This resilience makes it suitable for deployment in harsh settings like factory floors, warehouses, and outdoor enclosures where standard commercial-grade equipment would fail. The inclusion of redundant power inputs and an alarm relay output further ensures continuous operation and immediate fault notification, which are critical for maintaining uptime in mission-critical industrial applications. Deployment is simplified with versatile mounting options, including both DIN-rail and wall mount kits. The TI-M42 is equipped with four DB9 serial ports and two 10/100Mbps Ethernet ports, allowing flexible connectivity for multiple devices and network redundancy. Configuration and management are handled through a straightforward web-based interface or via Telnet, providing network administrators with familiar tools to control Modbus RTU/ASCII Master/Slave settings and network parameters.
