The MHX-920 is a long range - high speed 900MHz Frequency Hopping Spread SpectrumModem. The MHX-920’s rate can be optimized for long distance communication over60 miles. MHX-920 radios offer the fastest communication over the longest distances.MHX-920 OEM Industrial Wireless ModemApplications:- SCADA (PLCs, Modbus, HART)- Telemetry- GPS Vehicle Data/Tracking, DGPS- Electric, Oil, & Gas Utilities/Metering- Display Signs- Traffic Control, Loop detectors- Transparent low latency communicationIf you thought our MHX-910 was good - you’llbe amazed with the MHX-920. There aremany radios that make claims - just run ourradios 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 dataserial 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 continuousthroughput to support protocols such as MODBUS•License-free communication in the 902 - 928 MHz ISM band•Industrial Grade - extended temperature specification•Supports point-to-point, point-to-multipoint, Store and ForwardRepeater, TDMA, Multimaster•Maximum allowable transmit power, (1W)•Low power consumption in Sleep Mode and High Voltage Option•32-bit CRC, selectable forward error correction with retransmit•Separate diagnostics port - transparent remote diagnosis andonline network control•Backwards and Footprint Compatible with MHX-910 andSpectra-910 radiosMHX-920 HV OptionPreliminary Specifications subject to change without NoticeRev 1.0
