The MHX-920 is a long range - high speed 900MHz Frequency Hopping Spread Spectrum
Modem. The MHX-920’s rate can be optimized for long distance communication over
60 miles. MHX-920 radios offer the fastest communication over the longest distances.
MHX-920 OEM Industrial Wireless Modem
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 - you’ll
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.
Features of the MHX-920
•Transparent, low latency link providing true 230 kbps continuous
throughput to support protocols such as MODBUS
•License-free communication in the 902 - 928 MHz ISM band
