GE MDS SDM4-1 Quick Start Manual

1.0 INTRODUCTION
The MDS SDM4-1 transceiver
software-configurable, industrial Master Station
solution for use in wireless telemetry applications. In
this guide, the term SD is used for information
common to all models of the radio. This radio module
is designed for use with a card cage and backplane
similar to that shown in Figure 3, and to be used with
a variety of data control equipment such as remote
terminal units (RTUs), programmable logic controllers
(PLCs), flow computers, and similar devices. Data
interface connections may be made by both serial
(RS-232/485) and limited Ethernet protocols.

2.0 INSTALLATION
There are three main requirements for installing the
transceiver:
• Adequate and stable primary power
• An efficient and properly installed antenna system
• Correct interface connections between the
transceiver and the data device.

Figure 2 shows a chassis with card cage and
backplane that this module would be typically installed
in. The backplane provides the 24V power
connection to this unit and provides the customer data
interfaces through the card edge connector on the
rear of the SDM4-1.

Chassis. The SDM4-1 modules may be installed in
any free peripheral slot of this chassis.
Figure 3 shows a typical installation of the radio.
NOTE: Retrofit Kits are available to simplify
installation at former MDS x710 digital and analog
sites. Consult the Reference Manual for ordering
details.

antenna connection in rear, with power and data
connections in the front.
2.1 Installation Steps
1. Install the transceiver into chassis as shown in
Figure 2.
NOTE: To prevent damage to the SDM4-1 radio,
wear a wrist strap to prevent ESD discharge to the
card edge connector. Also, dress all cables as
required to prevent moisture from running along the
cables and into the radio.
