1.0 INTRODUCTION

This guide presents installation and operating instructions for the MDS 4790M
master station (scanner) radio. It begins with an overall description of the
radio's features and is followed by the steps required to install the radio and
place it into normal operation.
Additionally, the guide contains troubleshooting tips for resolving system
difficulties that may be encountered. After you install the radio, we
recommend keeping this guide near the radio for future reference.

2.0 PRODUCT DESCRIPTION

The MDS 4790M master station (Figure 1) is a full duplex radio designed to
operate with MDS 4710 remote (outstation) transceivers in the fixed telemetry
and telecontrol radio services bands of 457.5 to 458.5 MHz and 463.0 to
464.0 MHz. It is designed for compliance with the United Kingdom's MPT
1411 specifications for radio performance and frequency assignment criteria.
Typical applications include utility Supervisory Control and Data Acquisition
(SCADA), distribution automation, online transactional processing and other
point-to-multipoint applications. The radio is available in either a redundant
configuration or a non-redundant configuration. Refer to Section 2.2,
Redundant versus Non-redundant Operation, beginning on page 3 for further
description.
The radio uses microprocessor control and Digital Signal Processing (DSP)
technology to provide highly reliable data communications even under adverse
conditions. DSP adapts to differences between components from unit to unit,
and ensures consistent and repeatable performance in ambient temperatures
from –30 to +60 degrees Celsius. The use of Digital Signal Processing
eliminates the variations in modem operation that can degrade the performance
of analog circuits.
The radio is designed for trouble-free operation with data equipment provided
by other manufacturers, including Remote Terminal Units (RTUs), flow
computers, automatic banking machines, programmable logic controllers
(PLCs), and others.
NOTE: Some features may not be available on all radios, based on the
options purchased. Consult the factory for information on feature
upgrades or available accessories.
