GE MDS SD 1 Quick Start Manual

1 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 con-
trollers (PLCs), flow computers, and similar devices. Data inter-
face connections support both Ethernet and serial (RS-232/485)
protocols.

1.1 Additional Information

This Setup Guide covers the essential installation and startup for
all SD transceivers except those operating in x710 mode. Alter-
nate information is available in English, (see 05-4846A01 Tech-
nical Manual). GE MDS manuals, Setup guides, Firmware, driv-
ers and Application Notes are available free of charge at

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 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.

NOTE: Retrofit Kits are available to ease installation at former
MDS x710 digital and analog sites. Consult your factory repre-
sentative 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 ca-
bles to prevent moisture from running along the cables and into
the radio.

2. Install the antenna and feedline. The antenna must be de-
signed 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.
