DataMover SS

Now available in:

  • 902-928 MHz ISM Band
  • 2.406-2.482 GHz ISM Band

Technical Information

The SIMREX DataMover SS-900 and SS-2.4 utilize FHSS (Frequency Hopping Spread Spectrum) in the ISM Band of 902 – 928 MHz or 2.406-2.482 GHz to provide reliable long range data transportation at up to 115.2 kbps. The DataMover SS provides transparent data communications for nearly all SCADA/Telemetry and EFM protocols including MODBUS.

Any SIMREX DataMover SS may be configured as a repeater extension. This allows store and forward data operation to extend the operating range of the network. Mulitple repeaters may exist at any level of the network preventing a single radio failure from disabling the entire network. There is no limit to the number of repeaters which may be used.

Why consider an DataMover SS solution?

  • High system performance and data integrity! Robust construction, digital signal processing (DSP) technology with self-equalization, automatic CRC/ARQ and powerful forward error correction.
  • Flexibility and rapid installation! Quick return on investment due to plug-and-play installation. License-free radio design with the ability to communicate with any asynchronous protocol without extra software or additional programming.
  • Performance under the most adverse conditions! Robust design provides excellent performance in the face of interference or difficult signal paths.
  • Small footprint! Exceptionally small design allows installation inside RTU or PLC housing.
  • SIMREX network-wide diagnostics software simplifies tasks and reduces the cost of managing the network infrastructure by eliminating trips to the field. Provides a non-intrusive means of maintaining link and radio network performance.
  • Flexible interfaces! All DataMover SS come equipped with RS-232 for direct connection to most RTU/PLC’s and RS-485 for multidrop environments.
  • Low Power Consumption! Sleep mode for extremely low power consumption requirements - typically draws 3 mA - yet still recovers quickly for fast access to your critical data.
  • SIMREX DataMover SS is the price/performance leader; offering flexibility and reliability for both point-to-point and point-to-mulitpoint requirements.


  • High Speed Throughput – 115.2 Kbps
  • Unparalleled Robustness – Forward error correction, CRC/ARQ, multiple resends
  • Industrial grade – Extended -40° C to +70° C temperature range for trouble free operation in extreme environments
  • Sleep Mode – ~ 3mA, ideal for solar power applications
  • Store and Forward - with self-healing networks
  • Network wide diagnostics – Central network control without the need to visit sites
