Product Description

Data-Linc’s SRM6030 is a 900 MHz serial modem from the SmartSpectrumTM Radio Modem Family. It offers reliable, versatile, and high-performance wireless data communication. The modem features improved hardware, including a faster processor, while maintaining compatibility with the older SRM6000 model.

Like its predecessors, the SRM6030 serial radio modem employs FHSS (Frequency Hopping Spread Spectrum) technology with proven data communication reliability, in the 900MHz ISM frequency band. Data-Linc’s robust modem allows customers to implement a proprietary wireless network in high RFI/EMI environments with the benefit of confidence in unsurpassed data communication integrity, including areas of existing wireless infrastructure.

Configurable through software, the SRM6030 has a separate DB9 serial port for easy access to the configuration software. Data-Linc’s SetLincTM software simplifies setup and configuration, with the option of remote web configuration.

The SRM6030 supports point-to-point and point-to-multipoint network topologies, allowing for an unlimited number of radios. Each modem can be individually configured as Master, Remote, Repeater, or Repeater/Remote using Config-LincTM software. The modem offers AES-256 encryption for enhanced security and boasts a long-distance range of 25 miles (40 km) with line-of-sight, extendable with Repeaters and high gain antennas.

Overall, the SRM6030 serial modem by Data-Linc maintains the company’s reputation for superior reliability, versatility, and performance in wireless industrial data communication.

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.

Industrial Applications

The SRM6030 is ideal for industrial automation systems with:

  • PLCs located on moving platforms, overhead cranes and turntables or other revolving equipment
  • Remote PLC programming
  • SCADA systems, such as water/wastewater, utilities and oil/gas systems
  • Underground or off-shore communications
  • High RFI environments (e.g., steel, manufacturing)
  • Industrial automation machine control on plant floors
