Product Description

License-free SRM6130 utilizes Smart Spectrum technology which is ideal for critical applications that demand reliable and secure data communication.

  • Superior reliability, versatility, and performance for wireless serial transmission
  • Unsurpassed range of up to 15 miles (24 km) with line-of-sight and omnidirectional antennas, extendable with Repeaters and/or high-gain antennas
  • Next generation of the proven SRM6100 serial modem, fully backward compatible
  • FHSS technology, coupled with 32-bit CRC error detection and AES Encryption, ensures reliable and secure delivery of critical information
  • RF site surveys are usually unnecessary, and no FCC site license is required
  • Eliminates the need for hard wire or fiber cable, which can be expensive and difficult to install
  • Supports various configurations including point-to-point, point-to-multipoint, and multiple Repeaters if needed
  • Multipoint operation allows for an unlimited number of Remotes
  • Can function as a Repeater/Remote to extend range or communicate around obstructions
  • Does not require back-to-back radio modems for the Repeater function

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. The technology uses a unique combination of advanced frequency hopping, high radio frequency (RF) data rate, and sensitive RF receiver. It 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 for long-range communication with easy-to-install omnidirectional antennas.

Industrial Applications

The SRM6130 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
