SRM6230 Radio Modem
Long-range, license-free 900 MHz Ethernet & Serial wireless communications engineered for maximum data integrity in high RFI/EMI noisy environments.
About This Product
Data-Linc’s license-free SRM6230 Ethernet Radio Modem offers exceptional reliability, versatility, and performance for industrial wireless data communications. Built with a faster modern processor, the SRM6230 maintains total backward compatibility with corresponding legacy models. Powered by SmartSpectrum™ FHSS technology, it ensures maximum data integrity across long distances without requiring an FCC site license.
SmartSpectrum™ FHSS Noise Immunity
Combines a 188 kbps RF data rate with high receiver sensitivity (-108 dBm) to bypass severe RFI/EMI noise and plant floor interference.
Seamless Legacy Replacement
100% backward compatible to replace aging SRM-series Ethernet modems on existing plant networks without rewriting PLC code.
AES-256 Industrial Security
Hardware-level 256-bit AES encryption and 32-bit CRC error detection safeguard critical SCADA and PLC control networks.
Flexible Operating Topologies
Software configurable as Master, Remote, Repeater, or Remote/Repeater through included Set-Linc™ software to support unlimited network nodes.
Why this matters?
Industrial automation environments—such as steel mills, water treatment facilities, and refineries—are packed with high electrical noise (EMI/RFI), heavy machinery, and physical line-of-sight obstructions. Conventional Wi-Fi or consumer radios fail constantly under these conditions, causing dropped PLC packets, emergency shutdowns, and costly unscheduled downtime.
The SRM6230 solves this challenge by leveraging proprietary SmartSpectrum™ frequency hopping. By transmitting across user-adjustable hop patterns in the license-free 900 MHz band, it delivers rock-solid, uninterrupted data transfer over distances up to 25+ miles (40 km).
