PRODUCT DESCRIPTION
The master station radio (
Figure 1
) is a full-duplex data telemetry radio
suitable for use in Multiple Address System (MAS) and Supervisory
Control and Data Acquisition (SCADA) applications. The radio uses
microprocessor control and Digital Signal Processing (DSP) technology
to provide highly reliable communications even under adverse condi-
tions.
The MDS 4790 is intended to be used in systems with compatible
MDS 4710 Series remote radios; it operates in the 400 MHz frequency
band (380 to 512 MHz for A and C models; 400 to 480 MHz for E
models). The MDS 4790S uses an over-the-air data rate of 9600 bps.
The MDS 9790 is used with compatible MDS 9710 Series remote
radios, and it operates between 800 and 960 MHz. Radios are available
in either a redundant configuration or a non-redundant configuration.

Section 2.2,
