FCC Part 15 Notice
Users must comply with the following requirements:
Operation of this device is subject to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that may
cause undesired operation. Any unauthorized modification or changes to this device without the express
approval of the manufacturer may void the user’s authority to operate this device. Furthermore, this device

Failure to comply with these instructions may void the user’s authority to operate this device.
CSA/us Notice
This product is pending approval for use in Class 1, Division 2, Groups A, B, C & D Hazardous Locations.
Such locations are defined in Article 500 of the National Fire Protection Association (NFPA) publication
NFPA 70, otherwise known as the National Electrical Code. The transceiver has been recognized for use
in these hazardous locations by the Canadian Standards Association (CSA) which also issues the US mark
of approval (CSA/US). The CSA Certification is in accordance with CSA STD C22.2 No. 213-M1987.
CSA Conditions of Approval: The transceiver is not acceptable as a stand-alone unit for use in the
hazardous locations described above. It must either be mounted within another piece of equipment which
is certified for hazardous locations, or installed within guidelines, or conditions of approval, as set forth
by the approving agencies. These conditions of approval are as follows:
The transceiver must be mounted within a separate enclosure which is suitable for the intended application.The antenna feedline, DC power cable and interface cable must be routed through conduit in accordance with the National Electrical Code.
Installation, operation and maintenance of the transceiver should be in accordance with the transceiver's
installation manual, and the National Electrical Code. Tampering or replacement with non-factory components may adversely affect the safe use of the transceiver in hazardous locations, and may void the
approval. A power connector with screw-type retaining screws as supplied by GE MDS must be used.
Do not disconnect equipment unless power has been switched off or
the area is known to be non-hazardous. Refer to Articles 500 through
EXPLOSION
HAZARD!
502 of the National Electrical Code (NFPA 70) for further information
on hazardous locations and approved Division 2 wiring methods.
INTRODUCTION
This guide presents basic installation and operating instructions for the
MDS SD9 Series wireless transceiver.
The transceiver (Figure 1) is designed to operate in point-to-multipoint environments, including utility automation/distribution systems,
and other telemetry functions.
These radios are software-configurable to provide flexible operation
in a variety of applications using one hardware platform. They employ
microprocessor control and Digital Signal Processing (DSP) technology to provide robust communications even under adverse conditions.
Figure 1. SD9 Data Transceiver
The transceiver is designed for trouble-free operation with data equipment provided by other manufacturers, including remote terminal
units (RTUs), programmable logic controllers (PLCs), flow computers, transaction terminals, and similar devices.
NOTE:
Some features may not be available on all units, based on the
options purchased and the applicable regulatory constraints
for the region in which the radio will operate.
Front Panel Connectors
Figure 2 shows the interface connectors and indicators on the trans-
ceiver’s front panel. These items are referenced in the installation
steps given later in this guide.

INSTALLATION
There are three main requirements for installing the transceiver:
• Adequate and stable primary power
• An efficient and properly installed antenna system
• Correct data connections between the transceiver and the data
device.
Figure 3 shows a typical remote station arrangement. This is followed
by step-by-step procedures for installing the transceiver and making
front panel connections.

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.
