Product Description

Data-Linc’s SRM6030 is a serial radio modem that offers superior reliability, versatility and performance for wireless serial data communications. This latest version offers improved hardware with a faster processor, while maintaining Data-Linc’s commitment to backward compatibility with its corresponding legacy versions, such as the acclaimed SRM6000 and its variations.

Like its predecessors, the SRM6030 Serial radio modem employs SmartSpectrum™ FHSS (Frequency Hopping Spread Spectrum) technology in the 900MHz ISM frequency band for robust communications. This allows customers to implement a proprietary wireless network in high RFI/EMI noisy environments, including areas with existing wireless infrastructure, bringing the benefit of exceptional data integrity.

The SRM6030 is software configurable and has a secondary DB9 serial port for independent access to configuration and diagnostics software. For customer convenience and first-line diagnostics, the front panel includes LED status lights that provide direct access to critical information.

As with all members of the SRM Family of license free SmartSpectrum™ Radio Modems, the SRM6030 supports both point-to-point and point-to-multipoint network topologies with a virtually unlimited number of radios. Each radio can be individually configured as Master, Remote, Repeater or Remote/Repeater, through the included Config-Linc™ Software.

The SRM6030 not only provides superior security through AES 256 encryption but also offers a long distance range of 25 miles (40Km) with omni antennas and line-of-sight, farther with Repeaters and/or high gain antennas.

Smart Spectrum™ Frequency Hopping Technology

Data-Linc Group has optimized wireless communications for maximum reliability with Smart Spectrum frequency hopping technology. Smart Spectrum ensures reliable wireless communications without requiring an FCC site license. Smart Spectrum uses a unique combination of advanced frequency hopping, high radio frequency (RF) data rate and sensitive RF receiver.

Smart Spectrum uses a high RF data rate of 188 kbps to ensure adequate throughput data rates even with high interference. Additionally, the outstanding noise immunity when coupled with a sensitive RF receiver allows long range communication with easy-to-install omni directional antennas.
