Unlicensed Long-Range Operation
Utilizing the MURS frequencies, the two-watt RV-M5-M radio modem is the longest-range unlicensed radio modem on the market.

High Speed and Efficiency
The FireLine operated with over-the air data rates of 1200, 2400, 4800, or 9600 bps.
Faster rates for higher efficiency, or lower-speed for increased communication range.

Fully Programmable
Using industry-standard AT commands, the FireLine RV-M5-M may be configured for simple "Transparent" operation, or for more sophisticated systems, may be configured with network IDs, and hardware flow control. The FireLine modem may be configured to send

data in either a Packet Mode or Streaming

Data Mdde. Use Packets for reliability and

error-free communications, and use streaming for high-speed low-latency transmissions.

Serial Interface
A versatile RS-232 serial interface is utilized for both the user's data and to configure the data radio modem. Industry standard AT commands are used to configure it, and user data passes transparently from one modem to another.

Real-time diagnostics and statistics
Channel performance, RSSI, RF power, packet counters, and radio configuration are easily accessed. An Auto-Status feature enables the FireLine to periodically report its status and DC voltage.

Fully Integrated Design
The advanced VHF transceiver is integrated with a powerful 16-bit microprocessor-based modem in

one easy-to implement package.

The microprocessor simplifies the user interface,

make the data radio modem truly transparent.

Data In. Data Out. It also incorporates sophisticated SDP and FEC routines, allowing the modem to

receive data buried in noise and

interference that other modems cannot tolerate.

Flexible Addressing and Error Correction
The FireLine uses a 16 bit address with a 16 bit network mask, allowing for many devices to be

co-located without receiving each other, as well as

the creation of sophisticated network topologies.

User-programmable automatic error correction is

built in using an ARO method. If enabled, FireLine modems will automatically re-transmit data that is received with errors.
