GE MDS SD Series Setup Manual

1.0 INTRODUCTION
The MDS SD transceiver (Figure
industrial radio for use in wireless telemetry applications. Models
offered at the time of printing include: MDS SD2 (215-235 MHz),
SD4 (350-512 MHz), and SD9 (928-960 MHz). The term SD is
used for information common to all models of the radio.
The radio supports both polled and report-by-exception data net-
works, and interfaces with a variety of data control equipment such
as remote terminal units (RTUs), programmable logic controllers
(PLCs), flow computers, and similar devices. Data interface con-
nections support both Ethernet and serial (RS-232/485) protocols.

1.1 About This Guide
This guide covers all SD transceivers except those operating in
x710 mode. A more detailed Technical Manual is also available
(05-4846A01). Before installing this product, refer to the Technical
Manual for important warnings, cautions, and notes. SD manuals
are available in printed or electronic form. All manuals are available
free of charge at www.gemds.com.
1.1.1 x710 Mode—Different Manuals Required
The radio may be configured to emulate a corresponding MDS
x710 transceiver. For x710 mode information, consult these man-
uals instead:
• Setup Guide (05-4669A01)
• Technical Manual (05-4670A01)
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 equipment.
Figure 2 shows a typical installation of the radio.
NOTE: Retrofit Kits are available to ease installation at former
MDS x710 digital and analog sites. Consult your factory
representative for ordering details.
2.1 Installation Steps
In most cases, the steps given here are sufficient to install the
transceiver. Refer to the Technical Manual for additional details, as
required.

1. Mount the transceiver. Attach the supplied brackets to the
bottom of the transceiver case (if not already attached), using
the four 6-32 x 1/4 inch (6 mm) screws. Mounting bracket
dimensions are shown in
brackets are to be used, consult the Technical Manual for
instructions.
NOTE: To prevent moisture from entering the radio, do not mount
the case with the cable connectors pointing up. Also,
dress all cables to prevent moisture from running along
the cables and into the radio.

2. Install the antenna and feedline. The antenna must be
designed to operate in the radio's frequency band, and be
mounted in a location providing a clear path to associated sta-
tion(s). At Remote sites, aim directional antennas toward the
Master Station. Low loss coaxial feedline should be used and
it should be kept as short as possible.
3. Connect the data equipment. Connection may be made
using Ethernet signaling, Serial protocols (RS-232/RS-485),
or both.
• If Ethernet is to be used, connect your data equipment to the
front panel Ethernet port next to the PWR connector.
