2. Overview
The M8S RF Paging/Data radio modem is capable of high-speed narrow-band data
communications and POCSAG paging decoding. Its powerful microprocessor enables it to
perform as both a data radio modem and a paging receiver. It contains a receiver, a
transmitter, and modem, creating an easy-to-use transparent data radio link. The M8S’s
user interface is asynchronous digital data into and out of the M8S. Modem operation is
virtually transparent to the user and the configuration of the modem is via the user serial
port.
The M8S can be configured in either a paging decoder mode or a data modem mode. The
command-line interface is similar to Raveon’s other data radio products, and configuring
the mode is very easy. The M8S also has a digital input pin that may be used to electrically
change modem types between data modem and paging modes.
The M8S is an easy to use and 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.
