No longer is there a trade-off between the reliability and range of a licensed narrow-band telemetry radio, and the convenience of a license-free ISM radio. The RV-M3-M transceiver is a VHF narrow-band data radio operating on the license-free MURS channels. With a fantastic sensitivity of –120dBm and 2 watts of RF power out, the RV-M3-M is a great choice for SCADA, wireless security, and telemetry systems — And it sells for half the price of most UHF narrow-band radios.
RV-M3-M VHF MURS band data transceiver, 2 watts
For those short-range, last half-mile applications, the RV-M1 data transceiver is an ultra-low-cost radio module operating in the 915MHz unlicensed ISM band. With a range of 500ft obstructed, and 1 mile line-of-sight, this little transceiver module transparently sends data like any expensive licensed radio, yet consumes less than 30mA of power and costs less than the antenna for most other radios. It also has digital I/O capability for simple remote control and telemetry information.
Raveon Features for Monitoring and Remote Control
These features are available in the FireLine series of RF modems as well as the MURS RV-M3 OEM radio module.
High-speed over the air data rates. 19200bps in 25kHz channel, 9600bps in 12.5kHz.
Remote status monitoring including DC voltage, packet error statistics, modem “up time”, and receiver signal strength.
Easy to use. Plug-in, Turn-on, and GO. Transmit data in = Receive data out.
Remote “PING” From any FireLine modem, a user may send a “PING” to any other FireLine modem to find out the link signal strength. This allows quick diagnostics, easy antenna alignment, and reduced site visits.
Lowest current draw in industry. Most FireLine wireless modems draw less than 110mA when fully operational, and some are less than 100mA.
Wide input voltage with high-efficiency switching voltage regulator.
Packetized AND Streaming Data. Integrated Packetized data protocol with error correction and built-in Streaming Real-Time operation. User selectable.
ARQ error correction and re-transmission capability. Totally transparent to the application.
Capable of store-and-forward repeating operation. (Due to FCC regulations, this is not available in the MURS band products)
Small size. Extruded aluminum enclosure is small, and very rugged.
16 bit addressing for up to 65,525 different unique device addresses per channel. Radio channels may be shared with no interference between users.
Supports group and broadcast transmissions. Network mask allows groups of any size.
Easily to configure. FireLine modems are configured using “AT” commands through the modem’s serial port. The same way all telcom/hayes type modems operate. There is no need for a separate serial link to the modem to configure or manage it.
RS-232 serial input and output. Programmable serial baud rates up to 57600 make the FireLine compatible with most every PLC, PC, and HMI device made.
Programmable over-the-air data rates. With the FireLine, YOU can choose how your system will work. Set the OTA data slower for extended communication range, or set it fast for lowest latency. Your choice.
SkyLine compatibility mode for use in older Sonik radio systems.
