    Trio License-free Radios

        • K-Series Ethernet Remote Radio
                Trio K-Series frequency-hopping, spread-spectrum data radios set the standard for reliable and secure serial data communication in the license-free 900 MHz and 2.4 GHz ISM bands. With unique features like LinkXtend™ for single radio store-and-forward, and ChannelShare™ collision-avoidance for support of spontaneous SCADA messages, K-Series radios provide the flexibility to allow implementation of even the most complex wireless solutions with virtually unlimited expansion capability.

          The industrial strength K-Series is ideally suited for the most demanding Point-to-Multipoint, Point-to-Point, and SmartPath™ mesh-like wireless Telemetry and remote SCADA applications, and is available in a fully enclosed housing (KR) as well as small-format DIN rail-mountable (KP), board-only (KB), and OEM module (OM) variants.
        • 256 kbps high speed over-air data rate (can be reduced to 128 k, 64 k or 32 k for longer range)
        • Advanced error free data delivery with CRC plus selectable FEC and ARQ.
        • Suitable for most industry standard data protocols. e.g. Modbus, DNP3, IEC870-5-101, etc.
        • MultiStream™ simultaneous data stream delivery allows for multiple vendor devices/protocols to be transported on the one radio network - compatible with Trio E-Series and M-Series
        • Flexible data stream routing providing optimum radio channel efficiency
        • 10-30 V DC power supply (13.8 V DC nominal)
        • Operating temperature range of -40 to 70ºC (-40 to +185 ºF)
        • 900 MHz: Class 1, Div 2, Groups A, B, C & D Hazardous Approval
        • 2.4 GHz : ATEX II 3G Ex nA IIC T4
