DATA-LINC GROUP's SRM7210E Wireless Ethernet Modem offers superior reliability, versatility and performance. The SRM7210E is factory pre-configured for easy, hassle-free installation. It offers an unsurpassed rated range of up to 20 miles (32 km) in optimal conditions with line-of-sight and an omni directional antenna, farther with Repeaters. Based upon proven technology, the SRM7210E adds flexibility to system design by providing a highly reliable wireless alternative in a compact package for a broad array of applications, even those where hazardous environments require Class 1 Div 2 .

The SRM7210E employs Wideband Frequency Hopping Technology in the 902-928 MHz frequency band for high speed secure and robust communication. DATA-LINC GROUP’s Wideband Frequency Hopping Technology enables the SRM7210E to reliably deliver critical communications at higher speeds than conventional Frequency Hopping Spread Spectrum radio modems.

RF site surveys are usually unnecessary and an FCC site license is not required. The SRM7210E wireless technology eliminates the need for hard wire or fiber cable, which are often expensive and difficult to install.

The SRM7210E offers easy to read LEDs and affords maximum installation flexibility, including optional DIN rail mounting. It can bridge two Ethernet segments or connect multiple Ethernet nodes to a Master PLC. The SRM7210E offers a 10BaseT (UTP) interface to the Ethernet device, uses MAC layer filtering and fully supports most Ethernet protocols for true protocol transparency.

The SRM7210E supports a number of configurations, including point-to-point and point-to-multipoint as well as multiple Repeaters if required. Multipoint operation permits an unlimited number of Remotes. It can also function as a Repeater/Remote to extend range or work around obstructions. Back-to-back radio modems are not required for Repeater function but can be used to maximize data throughput.

As with all DATA-LINC products, support services such as pre-sale project consultation, post-sale tech support with PLC expertise and site survey planning assistance are part of the DATA-LINC GROUP commitment.

It is also fully compatible with LincView^TM OPC diagnostic software for diagnostic software for real-time RF network monitoring.
