QUICK START GUIDE
Below are the basic steps for installing the transceiver. Detailed instructions are provided in “Installation
Steps” on Page 9 of this manual.
1. Install and connect the antenna system to the radio
• Use good quality, low loss coaxial cable. Keep the feedline as short as possible.
• Preset directional antennas in the direction of desired transmission/reception.
2. Connect the data equipment to the radio’s INTERFACE connector
• Connection to the radio must be made with a DB-25 Male connector. Connections for typical systems are shown below.
• Connect only the required pins. Do not use a straight-through RS-232 cable with all pins wired.
•Verify the data equipment is configured as DTE. (By default, the radio is configured as DCE.)
3. Apply DC power to the radio (10.5–16 Vdc @ 2.5 A minimum)
• Observe proper polarity. The red wire is the positive lead; the black is negative.
4. Set the radio’s basic configuration with a Hand-Held Terminal (HHT)
• Set the transmit frequency (
TX xxx.xxxxx
).
• Set the receive frequency (
RX xxx.xxxxx
).
• Set/verify the data rate using the
BAUD
command. The default setting is
BAUD 4800 8N1
. (Refer to
“TRANSCEIVER PROGRAMMING” on Page 17 for command details.)
5. Verify proper operation by observing the LED display
• Refer to Tab le 5 on Page 16 for a description of the status LEDs.
•Refine directional antenna headings for maximum receive signal strength using the
RSSI
com-
mand.

IN CASE OF DIFFICULTY...
MDS products are designed for long life and
trouble-free operation. However, this equipment, as with all electronic equipment may
have an occasional component failure. The
following information will assist you in the
event that servicing becomes necessary.
FACTORY TECHNICAL
ASSISTANCE
Technical assistance for MDS products is
available from our Customer Support Team
during business hours (8:00 A.M.–5:30 P.M.
Eastern Time). When calling, please give the
complete model number of the radio, along
with a description of the trouble symptom(s)
that you are experiencing. In many cases, problems can be resolved over the telephone,
without the need for returning the unit to the
factory.
Please use one of the following means for
product assistance:
Phone: 585-241-5510
E-mail: techsupport@microwavedata.com
Web: www.microwavedata.com
FAX: 585-242-8369
FACTORY REPAIRS
Component-level repair of radio equipment is
not recommended in the field. Many compo-
nents are installed using surface mount technology, which requires specialized training
and equipment for proper servicing. For this
reason, the equipment should be returned to
the factory for any PC board repairs. The
factory is best equipped to diagnose, repair and
align your radio to its proper operating specifications.
If return of the equipment is necessary, you
will be issued a Service Return Order (SRO)
number. The SRO number will help expedite
the repair so that the equipment can be repaired
and returned to you as quickly as possible.
Please be sure to include the SRO number on
the outside of the shipping box, and on any
correspondence relating to the repair. No
equipment will be accepted for repair without
an SRO number.
A statement should accompany the radio
describing, in detail, the trouble symptom(s),
and a description of any associated equipment
normally connected to the radio. It is also
important to include the name and telephone
number of a person in your organization who
can be contacted if additional information is
required.
The radio must be properly packed for return
to the factory. The original shipping container
and packaging materials should be used whenever possible. All factory returns should be
addressed to:
When repairs have been completed, the equipment will be returned to you by the same shipping method used to send it to the factory.
Please specify if you wish to make different
shipping arrangements. To inquire about an inprocess repair, you may contact our Product
Services Group at: 585-241-5540 (FAX: 585242-8400) or vie e-mail at:

RF Safety Notices
MDS 1710, 5 Watts
The radio equipment described in this guide emits radio frequency
energy. Although the power level is low, the concentrated energy from a
directional antenna may pose a health hazard. Do not allow people to
come closer than 1.80 meters to the front of the antenna when the transmitter is operating with a 7 dBd (9.15 dBi) gain antenna. Use of higher
gain antennas means increasing the distance accordingly.
This manual is intended to guide a professional installer to install,
operate and perform basic system maintenance on the described radio.
MDS 2710A/C, 2 Watts
The radio equipment described in this guide emits radio frequency
energy. Although the power level is low, the concentrated energy from a
directional antenna may pose a health hazard. Do not allow people to
come closer than 0.425 meters to the front of the antenna when the
transmitter is operating with a 0 dBd (2.15 dBi) gain antenna. Use of
higher gain antennas means increasing the distance accordingly.
This manual is intended to guide a professional installer to install,
operate and perform basic system maintenance on the described radio.
MDS 2710D, 5 Watts
The radio equipment described in this guide emits radio frequency
energy. Although the power level is low, the concentrated energy from a
directional antenna may pose a health hazard. Do not allow people to
come closer than 1.50 meters to the front of the antenna when the transmitter is operating with a 7 dBd (9.15 dBi) gain antenna. Use of higher
gain antennas means increasing the distance accordingly.
This manual is intended to guide a professional installer to install,
operate and perform basic system maintenance on the described radio.

1.0 GENERAL
1.1 Introduction
This guide presents installation and operating instructions for
MDS 1710A/C and MDS 2710 A/C/D series digital radio transceivers.
These transceivers (Figure 1) are data telemetry radios 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. They use microprocessor
control and Digital Signal Processing (DSP) technology to provide
highly reliable communications even under adverse conditions.
MDS 1710/2710 Series radios use continuous-phase frequency shift
keying (CPFSK) modulation with root duo-binary filtering (the sum of
two Nyquist-shaped, root-raised cosine responses). Demodulation uses
a Virterbi decoder and equalization with soft decision decoding.
Modulation and demodulation is accomplished using Digital Signal Processing (DSP). DSP adapts to differences between components from
unit to unit, and ensures consistent and repeatable performance in
ambient temperatures from –30 to +60 degrees Celsius. The use of Digital Signal Processing eliminates the fluctuations and variations in
modem operation that can degrade the operation of analog circuits.
Figure 1. Transceiver Connectors and Indicators
The transceiver is designed for trouble-free operation with data equipment provided by many other manufacturers, including Remote Terminal Units (RTUs), programmable logic controllers (PLCs), flow
computers, lottery terminals, automatic teller machines, and others.
