General Information
SmartGen Micro Encoder is the quick and inexpensive way to have an RDS/RBDS presence.
The SmartGen Micro is able to transmit basic RDS information such as the Program Service
name(PS), Program Identication(PI), Alternative Frequencies(AF), Program Type(PTY).
Decoder Information and Music / Speech ag are also supported. USB connectivity makes it easy
to program the non-volatile memory using any PC and the supplied Windows®software. After
programming, the unit may be disconnected and re-installed at the transmitter site. Though it is
not capable of “dynamic” messaging with song titles, SmartGen Micro will identify your station
by format, display your station’s “street name”, and continuously transmit any station promo or
advertising message to your listeners.

OPERATING RECOMMENDATIONS
For the normal and reliable operation of the SmartGen Micro device we recommend to follow
the next list of instructions:
• Please, install the unit only in places with good air conditioning. The unit has been designed
for operation within an ambient temperature range extending from 10 to 50°C. But because
adjacent, less efcient equipment may radiate substantial second-hand heat, be sure that the
equipment rack is adequately ventilated to keep its internal temperature below the specied
maximum ambient. When installing, leave a clearance of at least 1 cm around the equipment
to allow air to pass freely.
• We do not recommend installation in rooms with high humidity, dusty places or other
aggressive conditions.
• Although it is expected that a SmartGen Micro will be installed close to exciters (or
transmitters of even higher-power!), please practice reasonable care and common sense in
locating the unit away from abnormally high RF elds.
• Please, use only already checked power supply cables and sources. The shielded cables
usage is strongly recommended.
• We strongly recommend connecting the device only to reliable power supply sources. In
case of unstable power supply, please use UPS (Uninterruptible Power Supply).
• Please, use the device only with placed top cover to avoid any electromagnetic anomalies
which may cause problems of the normal functionality of the unit.
• Please, connect SmartGen Micro only to good quality Internet connection. This is very
important for the normal remote operation of the unit.
• Please, check if your network settings pass through all the data trafc required for the normal
operation of the SmartGen Micro unit.
RADIO FREQUENCY INTERFERENCE (RFI)
Although we have anticipated SmartGen Micro installation in the immediate proximity of
broadcast transmitters, please do practice some care using the unit away from abnormally high RF
elds.

Unpacking and Inspection
IT IS VERY IMPORTANT that the Warranty Registration Card found at the front of this
Manual be completed and returned. Not only does this assure coverage of the equipment under
terms of the Warranty and provide a means of tracing lost or stolen gear, but the user will be sent
specic SERVICE OR MODIFICATION INSTRUCTIONS issued by DEVA Broadcast Ltd.
As soon as the equipment is received, inspect carefully for any shipping damage. If damage is
suspected, notify the carrier at once, and then contact DEVABroadcast Ltd.
We recommend that you retain the original shipping carton and packing materials, just in
case return or reshipment becomes necessary. In the event of return for Warranty repair, shipping
damage sustained as a result of improper packing for return may invalidate the Warranty!
Mounting
HEAT DISSIPATION
Consuming less power than the light in a refrigerator, the SmartGen Micro itself generates
negligible heat. The unit is specied for operation within an ambient temperature range extending
from freezing to 120°F/50°C. But because adjacent, less efcient equipment may radiate substantial
heat, be sure that the equipment rack is adequately ventilated to keep its internal temperature
below the specied maximum ambient.

RDS: Europe vs America
The European Broadcasting Union (EBU) and its member countries originated the concept of
“Radio Data” transmission. The European RDS specication, CENELEC Standard EN50067, was
rst published in 1984. It was revised in 1986, 1990, 1991 and 1992.
European RDS has grown in use following initial adoption of the Standard. RDS is nearly
universal throughout Europe; it is almost impossible to nd a European FM broadcasting station
that does not carry a radio data subcarrier.
The popularity of RDS in Europe is very much in contrast with initial reluctance on the part
of US broadcasters to embrace this technology. This can be ascribed to material differences in
broadcasting practices.
Almost without exception, FM broadcasting in the United States is ‘detached’and independent;
that is, each station originates its own programming. One exception might be America’s National
PublicRadio, thoughfor mostofthe broadcastday evenNPR stations originate,or atleast schedule,
their own programs.
Much of European broadcasting is similar to the concept of network radio that was common
in the US prior to the 1950s. In Europe, a central program originator may have many transmitting
facilities of modest power situated throughout the country, at several different frequencies to
blanket a designated service area. The European disposition toward lower-power transmitters can
be found on the “local radio” level as well.
The European concept of a service area equates to the US broadcaster’s market. The subtle
difference between these designations further characterizes broadcasting practices and ethics.
RDS benets the European broadcaster through almost an altruistic endeavor to be of service to
his listeners. The US broadcaster is marketing his programming, and is primarily interested in how
he can create additional revenue from RDS.
The RDS System
RDS is a digital data channel transmitted as a low-level subcarrier above the range of the
composite stereo program signal in the FM baseband. The data transmission (baud) rate is
comparatively low, yet it is quite robust because of data redundancy and effective error correction.
It is not within the scope of this Manual to cover the details of RDS subcarrier coding and
modulation. For this the reader is directed to the Specication appropriate to his location, either
the CENELEC EN50067 Specication for Europe, or the United States NRSC Specication. It
is assumed that the user has some familiarity with the concept of RDS, since the balance of this
Manual will deal with specic implication of RDS implemented with the SmartGen Micro.

RDS Applications Supported
The following is an alphabetical listing of RDS applications that are fully supported by the
SmartGen Micro. The standardized RDS application abbreviation is followed by an expansion of
the application name and a short explanation of the function.
PI
Program Identication: This block of data identies the broadcast station with a hexadecimal
numerical code, which becomes the “digital signature” of the station. The code is assigned by the
broadcasting authority in most countries, but in the US it is calculated from a numerical encoding
of station call letters. The receiver processes the PI code to assist automatic tuning features (station
memories), and to prevent false switching to alternative frequencies that might be shared by
broadcasters in nearby regions.
PS
Program Service Name: This is the station’s “street name” that will appear on the receiver
faceplate display. The PS can be up to eight characters in length (including spaces) and can be as
simple as the station’s call letters: KWOW or KWOW FM, or a slogan: NEWSTALK or LIVE 95.
The Program Service Name is automatically displayed, even on automobile receivers, and because
of driving safety considerations broadcasters are generally discouraged from scrolling messages
in this eld. As a matter of fact, it is a violation of both the CENELEC and the NRSC standards to
scroll the PS display, although the practice has become universally common.
PTY
Program Type: The PTY data ag identies the station format from a collection of pre-dened
categories. Many RDS receivers are able to seek the listener’s preferred format automatically.
This means that a car radio can switch from a fading station to a stronger one that carries the
same variety of music, though not the very same program, as provided by AF switching. The
PTY function of RDS helps a broadcaster catch ‘transient audience’ share. A listing of the PTY
categories is given in “APPENDIX A” on page 50 and “APPENDIX B” on page 51.
Under some programming circumstances, the PTY identier may be made ‘dynamic,’ changing
between categories for a station that “dayparts” (changes its format for specic time periods).
The PTY code is not meant to change from song to song or to accommodate a top-of-the-hour
newscast, however.
TA
Trafc Announcement: This is a temporary ag added to the RDS data stream only as a trafc
bulletin is being aired. Some RDS car radios can be set to search for trafc bulletins among various
TP stations (see TP below) while tuned to a listener’s preferred program, or even while playing
a tape or CD. As soon as any TP station broadcasts a trafc bulletin, the receiver temporarily
switches-over to receive it. When the bulletin is nished, the receiver switches back to the original
program, tape or CD.

- 18 -
TP
Trafc Program Identication: The TP ag identies the station as one that routinely
broadcasts trafc bulletins for motorists as part of its normal, everyday programming. When the
TP ag is displayed on the receiver faceplate, the radio is searching for trafc announcements. The
radio keeps track of TP stations offering this service to speed up the search-and-switch process.
M/S
Music / Speech Switch: This ag simply indicates whether music or speech is the primary
broadcast programming. The purpose of this function is not well explained in the respective
Standards; hence it comes as no surprise that it is not widely used.
DI
Decoder Information: This is one of several ‘ags’ that convey yes/no or other very basic data.
This particular ag tells the receiver whether the broadcast is monaural, or is being transmitted in
any of several methods of stereo or binaural broadcasting. As many as 16 encoding options may
be accommodated! This is a rather esoteric function and, thus far, remains unused both in Europe
and in the US.
AF
List of Alternative Frequencies: A network broadcaster, or one with low-power rebroadcast
transmitters (translators) to ll holes in his coverage area, can include a list of all frequencies where
the identical program can be heard simultaneously. The RDS receiver (particularly the upscale car
radio) constantly searches for the best signal that carries the very same program. When a better
signal is found, the radio re-tunes with no noticeable interruption. The principal utility of this RDS
function is with European radio networks and US stations with ‘translators.’
CT
Clock Time and date: Time and date codes should use Coordinated UniversalTime (UTC) and
Modied Julian Day (MJD). If MJD = 0 the receiver should not be updated. The listener, however,
will not use this information directly and the conversion to local time and date will be made in
the receiver’s circuitry. CT is used as time stamp by various RDS applications and thus it must be
accurate.
RT
RadioText: This is a 64-character block of plain text that the listener can select for visual
display on the faceplate of the radio by pressing an INFO button on the receiver. This function is
not available on many automobile radios for safety reasons, which has precipitated the frowned-
upon practice of scrolling the PS eld instead.
Most radios have limited alphanumeric display capability, so the 64 characters of RadioText
march across the front panel, much akin those annoying LED advertising signs found in airport
buses or fast food emporia. Like the scrolling-PS implementation, RadioText can announce song
titles and performers, run special promotions or contests, or broadcast sponsors’messages.

Selection of Operating Modes
SIDECHAIN MODE
Congured for sidechain operation, the rear-panel PILOT OR MPX INPUT connector simply
bridges (monitors) the output of the stereo generator to derive timing information from the 19kHz
stereo pilot. Alternatively, a TTL-level 19kHz sync squarewave may be applied to this input. We
do not recommend this, however, as the phase relationship between the synchronizing squarewave
and the 19kHz pilot component in the composite, multiplex output of the stereo generator may not
be assured.
In sidechain operation the RDS OR MPX OUTPUT will contain only the RDS subcarrier,
the composite/MPX signal is not routed through the SmartGen Micro. This operating mode best
preserves multiplex signal integrity and assures uninterrupted program transmission in the event
of a catastrophic encoder failure (very doubtful). As delivered, the SmartGen Micro is congured
for sidechain operation.
LOOP-THROUGH MODE
When the SmartGen Micro is congured for loop-through operation, the RDS subcarrier is
internally combined with the composite/MPX signal. This means that the RDS OR MPX OUTPUT
will include the composite/MPX program signal (at unity gain) with the RDS subcarrier added.
Also, in the loop-through mode the internal bypass relay will pass-through the multiplex signal in
the event of an encoder power failure.

Connecting The SmartGen Micro
IMPORTANT CONNECTION CONSIDERATIONS!
The SmartGen Micro encoder must be properly congured for the desired operating mode:
sidechain or loop-through before it is installed in the signal path. Use SmartGen Basic Encoder
Manager(see “Hardware & RDS Conguration” on page 35) to conrm that the encoder is properly
congured before connecting the SmartGen Micro to other air-chain equipment.
Also, it is important that the operating software be installed on the PC before it is connected
to the encoder for programming the ‘static’ message registers and operating defaults. In addition,
we heartily recommend testing the encoder with its controlling interface (computer, terminal,
automation, etc.) before it is placed in the air chain. This will ensure that 2-way communication
with the encoder can be established and that the encoder is properly initialized.
