1.0 GENERAL

1.1 Introduction

This guide presents installation and operating instructions for the

MDS 4710A/9710A and the MDS 4710C/9710C Series (400/900 MHz)

digital radio transceivers.

These transceivers (Figure 1) are data telemetry radios designed to

operate in a point-to-multipoint environment, such as electric utility

Supervisory Control and Data Acquisition (SCADA) and distribution

automation, gas field automation, water and wastewater SCADA, and

on-line transaction processing applications. They use microprocessor

control and Digital Signal Processing (DSP) technology to provide

highly reliable communications even under adverse conditions.

Modulation and demodulation is accomplished using Digital Signal Pro-

cessing (DSP). DSP adapts to differences between components from

unit to unit, and ensures consistent and repeatable performance in

ambient temperatures from –30 to +60 degrees Centigrade. The use of

Digital Signal Processing eliminates the fluctuations and variations in

modem operation that degrade operation of analog circuits.

The transceiver is designed for trouble-free operation with data equip-

ment provided by other manufacturers, including Remote Terminal

Units (RTUs), flow computers, lottery terminals, automatic teller

machines, programmable logic controllers, and others.
