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
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
online transaction processing applications. They use microprocessor
control and Digital Signal Processing (DSP) technology to provide
highly reliable communications 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 Celsius. The use of Dig-
ital 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.
NOTE: Some features are not available on all radios, based on the
options purchased and the applicable regulatory constraints for
the region in which the radio operates.
