Data-Linc’s 900 MHz serial member of the SmartSpectrumTM Radio Modem Family, the SRM6030, offers a license-free serial modem with superior reliability, versatility and performance for wireless data communication. This latest version provides improved hardware, such as a faster processor, while maintaining Data-Linc’s commitment to backward compatibility with its corresponding legacy version, the SRM6000.

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.

The SRM6030 is software configurable and has a separate DB9 serial port for independent access to configuration software. Data-Linc’s proprietary SetLincTMsoftware, that is included with the SRM6030 modems, simplifies modem setup and configuration— executed via the dual serial ports (RS-232 or RS-485). For remote sites, web configuration is also an option.

As with all members of the SRM Family of license-free radio modems, the SRM6030 supports both point-to-point and point-to-multipoint network topologies with a virtually unlimited number of radios. Each modem can be individually configured as Master, Remote, Repeater or Repeater/Remote using the included Config-LincTM software. Additionally, the SRM6030 provides not only superior security through AES-256 encryption but also offers a long distance range of 25 miles (40 km) with line-of-sight, farther with Repeaters and/or high gain antennas. The combination of features and benefits supplied by the SRM6030 serial modem continues to support Data-Linc’s well-earned reputation for superior reliability, versatility and performance for wireless industrial data communication.

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
