2. Overview
The M7 RF data radio is a rugged high-performance, high-speed narrow-band data modem. It contains a
receiver, a transmitter, and modem, creating an easy-to-use
transparent data radio link. The
M7’s user interface is
asynchronous RS-232 data into and out of the M7 (CMOS level
optional). Modem operation is virtually transparent to the user
and the configuration of the modem is via the user serial port.
Unlike any other radio modem on the market, the M7 may be operated in either a “ Packetized Mode ” or
a “ Streaming Real-Time Mode ”. There are advantages to each approach, and your choice depends upon
how your system operates.
For privacy and network versatility, the M7 incorporates a 16 bit identification code. Its protocol also
uses a 16bit CRC to guarantee the integrity of the data. Perfect for SCADA and telemetry applications,
the
M7 can be used for simple point-to-point data communication applications, or for more
sophisticated point-to-multipoint, peer-to-peer, or mesh networks.
Although the M7 is the easiest to use modem on the market, its re-programmability makes it extremely
versatile. Most parameters within the modem may be re-configured to optimize it for specialized
operations, extended range, or higher data throughput.
