04P10 MHX920 900MHz SPREAD SPECTRUM OEM TRANSCEIVER BROCHURE Users Manual

M H X - 9 2 0 O E M I n d u s t r i a l W i r e l e s s M o d e m The MHX-920 is a long range - high speed 900MHz Frequency Hopping Spread Spectrum Modem. The MHX-920s rate can be optimized for long distance communication over 60 miles. MHX-920 radios offer the fastest communication over the longest distances. Applications:

- SCADA (PLCs, Modbus, HART)

- Telemetry

- GPS Vehicle Data/Tracking, DGPS

- Electric, Oil, & Gas Utilities/Metering

- Display Signs

- Traffic Control, Loop detectors

- Transparent low latency communication If you thought our MHX-910 was good - youll be amazed with the MHX-920. There are many radios that make claims - just run our radios side by side and see what happens. The MHX-920 features robust, high speed, low latency, secure data communications. The MHX-920 has a full data serial port and a separate diagnostics port for real-time diagnostics; which does not interfere with data communi-

cations. MHX-920 offers excellent noise figure, superior interference rejection, very agile frequency synthesis, digital modulation, and matched filter detection. The MHX-920 can be user optimized for speed and distance.
