GENERAL
1.1 Introduction
This guide presents installation and operating instructions for
MDS 1710A/C and MDS 2710 A/C/D series 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.
MDS 1710/2710 Series radios use continuous-phase frequency shift
keying (CPFSK) modulation with root duo-binary filtering (the sum of
two Nyquist-shaped, root-raised cosine responses). Demodulation uses
a Virterbi decoder and equalization with soft decision decoding.
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 can degrade the operation of analog circuits.

The transceiver is designed for trouble-free operation with data equip-
ment provided by many other manufacturers, including Remote Ter-
minal Units (RTUs), programmable logic controllers (PLCs), flow
computers, lottery terminals, automatic teller machines, and others.
