Operating Instructions Part 2

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 radio transceivers. The radios can be purchased as
compact, modular boards for direct mounting inside remote terminal
units (RTUs), programmable logic controllers (PLCs), automatic
teller/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 with a 4-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.
NOTE: FINAL DESIGN WILL EMPLOY
A TWO-PIN, POLARIZED POWER
CONNECTOR.
