GENERAL
This guide presents installation and operating instructions for the MDS
9710B (900 MHz) and MDS 4710B (400 MHz) radio transceiver. For
brevity, the model number “MDS x710B” is used in this guide to repre-
sent both models, except where it is necessary to distinguish between the
two.
The transceiver (Figure 1) is a data telemetry radio suitable for Multiple
Address System (MAS) and Supervisory Control and Data Acquisition
(SCADA) operation. It uses microprocessor control and Digital Signal
Processing (DSP) technology to provide highly reliable communica-
tions even under adverse conditions.
These radios are designed for over-the-air compatibility with earlier
MDS remote transceivers such as the MDS 2300 and MDS 4300 Series
as well as the MDS 1000µ. The radios will operate in systems using
MDS 2100 and 4100 master stations.
An MDS 4710 is also available which is adherent to the United
Kingdom’s MPT1411 specifications for radio performance and fre-
quency assignment criteria. The MPT1411 compliant version of the
MDS 4710 is covered in MDS manual 05-3634A01.
