AN 119 Wireless System Design Top-Level Issues. (pdf) Raveon specializes in designing wireless data communication products with a keen focus on system requirements and long-range operation. When developing a new wireless system, there are many technical issues to consider. This paper outlines the major issues Raveon evaluates to create a product fit for a particular market as well as an overview of how Raveon’s made its system decisions for its LandScape™ System of wireless products.
AN 122 M7 and SCADA. (pdf) Raveon’s M7 series of data radios make ideal wireless modems for SCADA and telemetry systems. This Application Brief describes the general requirements for a wireless SCADA modem and then provides the information needed to configure a FireLine modem to work in common SCADA applications.
AN 131 M7 Data Radio Competitive Features. (pdf) The M7 data radio modem is a sophisticated radio modem, but also one of the easiest to use. AN131 details out many of its unique features that make it the right choice for your wireless modem requirements.
AN 136 Updating Firmware. (pdf) AN136 describes how firmware in the M7 data radio modem may be updated using the Phillips Flash File Utility. Ony in certain cases may an M7 be updated in the field. In most instances, the radio must be sent into the factory fo firmware updating.
AN 139 Using the M7 GX to send data in TDMA time Slots. (pdf) The GX option adds an internal GPS in the RV-M7 data radio. With this option, a TDMA protocol is also available for use to send position information AND to send data between modems. This application not describes how TDMA data in the RV-M7 series of radio works.
AN 140 Expanding Radio Coverage with a Terminal Server. (pdf) There are many ways to increase the area of coverage in a radio communication system. AN140 describes how a Terminal Server may be used to facilitate this.
AN 161 M7 MIMIC Mode. (pdf) The M7 data radio modem has a “MIMIC” mode for remote power control, wireless pump control, and many other remote control applications. See AN161 for details on how this works.
AN 180 Installing Bootloader Firmware. (pdf) This Technical Brief describes how to upload the “Bootloader” firmware into a Raveon
M7 series product. A Bootloader firmware program is an additional small program that
runs in the product when it is first turned on. It enables the product’s main firmware
program to be updated in the field.
AN 181 Reloading Firmware. (pdf) Summary of the firmware updating process using the built-in Bootloader. If your
Raveon product does not support bootloading, you will need to first install the Bootloader into
it. See AN180 for information on how to install the Bootloader.
AN 198 PTSAG Message output. (pdf) The M7 radio is capable of compatibility with GAPS systems using the $PTSAG message. This message will output GPS report information received over-the-air in the format described.
AN 199 Low-Latency Streaming. (pdf) This Tech note explains the uses of our Low-Latency Streaming capabilities on our M7 radio, for use in control of robotics and machinery from a distance with only milliseconds of a delay.
AN 232B-05. (.pdf) Configuring Baud Rates of the M7-USB interface. The M7-USB option replaces the standard DB9 RS232 serial connector on the M7 wireless modem with a USB 2.0 MINI-B connector and internal a USB-Serial bridge. All features and functions of the M7 remain available via the USB connection.
Remote Management of Raveon Wireless Modems. (pdf) Built into all FireLine and M7 series radio modems, is a set of unique remote management and diagnostic capabilities. With the most advanced modem management capabilities in its class, FireLine and M7 users are able to remotely read network statistics, configuration, and operating conditions of any data radio modem in the system.
TB115 Wireless Data Radio Usage of the FCC “MURS” Channels. (pdf) In the fall of 2000 the FCC of the United States created a new license free VHF Citizen Band Radio Service. The FCC defines MURS as a private, two-way, short-distance voice or data communications service for personal or business activities of the general public. This paper reviews the FCC regulations governing MURS, and highlights some of the advantages and drawbacks of using products designed for this service.
VHF/UHF/Microwave Radio Propagation: A Primer. (pdf) This paper provides insight into the nature of VHF and UHF radio propagation. It begins with the basics of free space path loss calculations, and then considers the effects of terrain, frequency, and many other system issues.
