This section describes the Registers stored in the Remote Autonomous Zone Node. Registers can be ready with commands, TOAA, or MODBUS messages. There area many registers that were stored by the RAZN as it monitors IO terminals and internal features and operations also. The number in the beginning of the description below is the Register […]

Years ago, the GPS (Global Positioning System) was created in America as a constellation of medium earth orbit satellites. Now many other countries can to tracking with the new Global Navigation Satellite Systems (GNSS) technologies. The frequencies used in various GNSS systems are: GPS: 1575.42 MHzGalileo: 1575.42 MHzGLONASS: 1602 MHzQZSS: 1575.42 MHzBeiDou: 1561.098 MHz

6.25kHz channels were split from 12.5 kHz channels by the FCC. Raveon’s RV-M6 data radio modem can operate on 6.25kHz, 12.5kHz, or 25kHz wide channels. Now the FCC licenses 6.25 kHz channels on “offset” frequencies within the previous 12.5 kHz channel 6.25 kHz channels are “dropped in” between existing 12.5 kHz radio channels. They allow […]

The DD1494 form is submitted in stages that coincide with the phases of the DoD acquisition process. RF performance and RF spectrum information are put into the DD form 1494 so the government can allocate frequencies for a radio. Raveon’s Data Radio modems are used on many different frequencies that were setup using DD1494 forms. […]

Electronic communications is all about interlinking circuits (processors or other integrated circuits) to create a symbiotic system. For those individual circuits to swap information, they must share a common standard communication protocol. Many communication protocols have been designed to achieve data exchange. The most common serial communication protocols are RS232, RS485, RS422, USB, and Ethernet.  […]

Pro2 Master Module Communications with wireless data modems and long-range RF

Overview LoRa is short for “Long Range”.  LoRa modulation scheme is a modulation technique combined with a data encoding technique that gives a broad-band spread-spectrum radio the receive sensitivity of a very narrow-band long range radio. Many people are not looking into what is LoRa, and this document describes LoRa and the advantages the LoRa […]
