MDS 05-3624A01, Rev. B OEM Series™ I/O Guide 1

1.0 INTRODUCTION

This guide presents installation and operating instructions for the MDS

OEM Series™ of digital radio transceivers. The radios can be purchased

as compact, modular boards for direct mounting inside remote terminal

units (RTUs), programmable logic controllers (PLCs), automatic

banking machines, or similar equipment. They are also available as

standalone units packaged in their own enclosures (see lower cover

illustration).

Although this manual focuses on the board-level product, the operating

specifications and user connections are identical for both versions of the

radio. Only the visual appearance and mounting details differ between

the two. These differences are explained in the text where necessary.

The transceiver (

Figure 1) is a data telemetry radio 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. The radio employs

microprocessor control to provide highly reliable communications, even

under adverse conditions.

MDS OEM Series™ radios use continuous-phase frequency shift

keying (CPFSK) modulation. Domestic models employ a 4-level

modem; ETSI models, a 2-level modem.

1.1 Differences Among Models

All OEM Series™ models are very similar in appearance and

functionality. The major differences are over-the-air modem speed and

frequency coverage.
