Spread Spectrum Radio (SSR)

  • Overview

    Wires are for the Birds...

    The SPREAD SPECTRUM RADIO provides a low cost alternative to point to point and point to multi-point wiring by allowing data to communicated wirelessly rather than over wires.

    Whether your requirement is accessing data from a site where no power is available or linking equipment together when using wires is cost prohibitive or the equipment you need to access is in motion then the SPREAD SPECTRUM RADIO is for you.

  • Spread Spectrum Technology: Frequency Modulation and Frequency Hopping algorithms ensure minimal interference from electrically noisy equipment and other environmental factors that normally degrade the integrity of wireless data telemetry.

    Low Power: Higher radio signal sensitivity and better filtering techniques means lower power requirements. This makes the SPREAD SPECTRUM RADIO perfect for those isolated sites where it is impractical or cost prohibitive to run power to. Use batteries or solar power instead.

    Transparent Operation: The SPREAD SPECTRUM RADIO can be used with any product whose protocol uses 7 or 8 bit asynchronous data transmission. This includes but is not limited to: ASCII MODBUS, RTU MODBUS, DF1 or DNP3.

    Hermetically Sealed: The SPREAD SPECTRUM RADIO is completely "potted" in silicon rubber making it impervious to the elements commonly found in harsh environments.

    RS232C/RS485: The SPREAD SPECTRUM RADIO may be wired either for a RS485 or RS232 system. When used with RS485 the Port will automatically switch to RS232C for configuration. Either full RS232C or 3 RS232C may be used.

    Compact Package: Due the small 3.0 X 1.2 X 2 inch size, the SPREAD SPECTRUM RADIO makes Mobile/Portable wireless data acquisition practical and affordable.
