2.0 PRODUCT DESCRIPTION
The SD Transceiver is a software-config rable, ind strial radio for se
in licensed data acq isition networks. It can be interfaced with a variety
of data control eq ipment incl ding remote terminal nits (RTUs), pro-
grammable logic controllers (PLCs), flow comp ters, and similar
devices. Data interface connections can be made for both serial
(RS-232/RS-485) and local Ethernet protocols.
The radio’s x710 Mode is designed primarily for se in serial MDS x710
radio networks where a central station comm nicates with each remote,
one at a time, to convey data and control signals. For models operating
in this mode, the radio offers direct, drop-in compatibility with existing,
older x710 networks while providing additional f nctionality not fo nd
in MDS x710 radios. An SD Transceiver in x710 mode looks like an
x710 with respect to over-the-air transmission and all serial ser inter-
face commands (pl s some new SD-specific commands).
The transceiver employs digital signal processing (DSP) technology and
a f lly digital transmit and receive IF chain to provide rob st comm ni-
cations even nder adverse conditions. Digital signal processing also
helps eliminate the effects of component variations or temperat re
swings, res lting in an optimized performance.

• D al serial f nctionality (RS-232 and RS-485)
• Software config rable sing the b ilt-in interface, and Web man-
agement—no man al controls or adj stments. S pports Serial,
Telnet, or web-based management.
• Over-the-air reprogramming—no nnecessary trips to radio sites
• Licensed 5-watt design, maximizes comm nications range with
low interference risk from other sers
• Config rable as a Remote or a Master nit
• Low power “sleep mode”—ideal for battery-powered solar sites
• Drop-in compatibility with MDS x710 radios (x710 mode)
• S pports a wide variety of modem speeds and bandwidths for
reg latory compliance in virt ally all regions of the world
NOTE: Some feat res might not be available on all nits, depending on the
options p rchased and reg latory constraints for the region in which
the radio will operate .
2.3 Mo el Offerings
The radio is available in three model config rations:
•Ethernet—All SD feat res and f nctionality
•Standard—All feat res except Ethernet f nctionality
•x710—Direct, drop-in compatibility for networks sing a mix of
SD and older MDS x710 radios. The Ethernet port is available for
radio management in x710 mode, b t not for payload.

2.4 Operating Mo es an Applicable Manuals
SD Transceivers can be config red to operate in any one of three modes:
•x710 Mode—This mode provides direct, drop-in compatibility
with MDS x710 (4710 or 9710) transceivers, and ses the same
core command set as these radios. It is ideal for se in systems
containing a mix of newer SD radios and legacy MDS x710 nits.
This manual covers x710 Mode radios.
•Pac et Mode (including Pac et w/MAC)—Payload data from
the radio’s serial or Ethernet ports is assembled into packets and
transmitted over the air. Packet mode s pports Ethernet Bridging,
AES 128-bit encryption, and m ltihost operation. This mode is
ideal for networks containing all SD radios. This manual does not
cover Packet Mode radios. See below for applicable manuals.
•Transparent Mode—This mode is over-the-air compatible with
MDS x710 transceivers, while s pporting payload data on the
Ethernet interface. This mode is ideal for mixed networks con-
taining SD and MDS x710 radios. It allows c rrently deployed
x710 networks to add the ability to s pport Ethernet data. This
manual does not cover Transparent Mode radios. See below for
applicable manuals.
For Packet Mode and Transparent Mode operation, refer instead to the
following man als for instr ctions:

3.0 APPLICATIONS
Point-to-Multipoint, Multiple A ress Systems (MAS)
This is the most common application of the transceiver. It consists of a
central master station and several associated remote nits as shown in
Fig re 4. An MAS network provides comm nication between a central
host comp ter and remote terminal nits (RTUs) or other data collection
devices. The operation of the radio system is transparent to the comp ter
eq ipment.
Often, s ch a system is sed to convey telemetry data to and from
widely separated remote radios. Typical applications incl de a tomatic,
remote monitoring of gas wells, water tank levels, electric power distri-
b tion systems, and similar control and meas rement f nctions.
The radio system can replace a network of remote monitors c rrently
linked to a central location sing leased telephone lines or other hard-
wired means. At the central office of s ch a system, there is s ally a
dedicated comp ter and some means of switching between individ al

lines coming from each remote monitor. In this type of system, there is
a mod lator/demod lator (modem) at the main comp ter and at each
remote site, s ally b ilt into the remote monitor itself. Since the cost of
leasing a dedicated-pair phone line is q ite high, wireless technology is
often sed as a cost-effective alternative.

Continuously-Keye versus Switche -Carrier Operation
The keying behavior of the master station can be sed to describe the
operation of an MAS system.
Continuously Keyed operation means the master station transmitter is
always keyed and an RF carrier is always present, even when there is no
data to send. The master station is always transmitting and receiving
sim ltaneo sly. Different freq encies m st be sed for transmit and
receive. This is the method sed in many MAS systems, as is shown in
Fig re 4. This network arrangement is sef l for high-speed polling
applications.
NOTE: The SDx acting as a master does not s pport f ll-d plex oper-
ation.
Switched Carrier operation is a half-d plex mode of operation where
the master station transmitter is keyed to send data and nkeyed to
receive.
Single-Frequency (Simplex) Operation
Single-freq ency operation (also known as simplex) is a special case of
switched-carrier operation. Single freq ency operation is a tomatically
selected whenever the transmit and receive freq encies are set to the
same val e.
NOTE: Data t rn-aro nd times are increased when inter-working with
an MDS x710 network. This restriction does not apply to
homogeneo s SD networks.
4.0 INSTALLATION PLANNING
Caref l planning of the installation site helps achieve optimal performance
from the transceiver. This section disc sses pre-installation factors. After
reviewing this section, refer to the step-by-step installation proced res begin-
ning on Page 18.
4.1 Typical Installation

4.2 Mounting Options
The transceiver is normally provided with flat mo nting brackets
attached to the bottom of the radio as shown in Fig re 7. An optional
35 mm DIN rail mo nting bracket is also available. See “Optional DIN
Rail Mo nting” on page 10.

NOTE: To prevent moist re from entering the radio, do not mo nt the
case with the cable connectors pointing p. Also, dress all
cables to prevent moist re from r nning along the cables and
into the radio.
Transceiver dimensions are shown in Fig re 8.

Optional DIN Rail Mounting
The nit can be mo nted with an optional 35 mm DIN Rail Mo nting
Bracket Kit (Part No. 03-4125A04). Eq ipment cabinets and racks of
modern design often employ this type of mo nting. Once the DIN
bracket is attached to the radio, it allows for q ick installation and
removal of the radio from its mo nting rail witho t the need for tools.
The DIN Rail bracket attaches to the nit’s case as shown in Fig re 9.
The entire assembly then attaches to the mo nting rail.
