4.1 Introduction
The necessi y o immedia ely know he working parame ers of several device in a
sys em or o ransmi wi h all he several uni s which have o manage a firm, is a
more and more grea er need in all circles.
The cordless broadcas ing , for i s simple ins alla ion and i s grea pliabili y, appears
as he more sui able solu ion in many circles.
In he broadcas ing field oo, he need o ransmi no only he radio signals, bu
also da a package of differen kinds, is already s rongly fel for many years, because
i allows o be er he quali y and he reliabili y of he available services and a he
end o implemen he new ones.
This necessi y is also fel in he in erna ional field, so much ha a proper research
eam has cons i u ed i self o iden ify he differen necessi ies and o de ermine a
broadcas ing s andard which would appear more proper for he sec or.
The eam has reached he "RADIO-DATA-SYSTEM (RDS)", which appears odays
he da a broadcas ing sys em more used in he radio field.
The TRDS4001 sys em allows o ransmi , wi h he radio signal (mono or s ereo),
a da a channel as specified in he paper "Specifica ion of he radio da a sys em
(RDS)", which is issued by he European Commi ee for Elec ro echnical
S andardiza ion (CENELEC) Ref. N° EN 50067.
4.2 RDSSystemDescription
The RADIO-DATA-SYSTEM is proper for he ransmission of informa ion in mono/
s ereo programs of VHF/MF (87.5-108 Mhz).
I sa isfies he reques ed requiremen s o he ransmission of supplemen ary da a
on radio programs:
1) Compa ibili y wi h he curren mono/s ereo ransmissions;
2) Absence of in erferences owards he adjacen programs;
3) Compa ibili y wi h o her iden ifica ion sys ems which are already working.
The sys em, selec ed by an in erna ional specialis ic eam, allows he da a
ransmission a a speed of 1187.5 bi /sec wi h phase modula ion a wo levels ,
carrier wave 57 Mhz and range ±2 Khz.
The broadcas ed binary signal is in advance pu ou on a differen ial codifica ion.

TRDS4001
8 / 18 User ManualRev. 5.2 - 23/06/06
The regis ry of ransmission is a packages of lengh 104 bi s (87.6 ms) named
GROUPS, each of hem composed of 4 blocks of 26 bi s.
Every block is composed of 16 bi s of informa ion and of 10 bi s of pro ec ion, which
are properly s udied o allow he recovery of an erroneous word wi h a maximum of 5
wrong bi s.
They are provided wi h 16 separe e blocks of which 6 are s ill no defined; every
group begins wi h a PI iden ifica ion code (Program Iden ifica ion) which has he
double in en o synchronize he receiver and o iden ify he channel which ransmi s
he signal.
The pourpose of he encoder TRDS4001 is o manage he principal services defined
by he s andard CENELEC EN 50067 as: PI, PS, PTY, TP, AF, TA, DI, M/S, PIN, RT,
EON, TDC, IH, CT.
As follows, well men ion a shor descrip ion abou he func ion of each of hese
services.
PI - PROGRAM IDENTIFICATION: i s he iden ifica ion code of he radio. I s more
impor an applica ion is o allow he receiver, in case of bad recep ion, o implemen
he "Au oma ic Frequency Change"; his happens when here is a signal wi h he
same PI and of be er level han he syn onized one.
PS - PROGRAM SERVICE: i s he visualized ex on he receiver display, which
has o be of maximum 8 charac ers, as his is he s andard dimension of receivers
displays. The TRDS4001 charac eris ic is o s ore up o 8 messages and he ime of
ransmission of each of hem. Every message can be composed from 1 o 16 words
of 8 charac ers, and i s possible o selec he permanence ime on he display of
each of he 16 separa e words.
PTY - PROGRAM TYPE: i s he iden ifica ion of he "Program Type" which is on air
(example News, Spor , Rock, e c.) I s used o qualify on he receiver he au oma ical
research of he program ype desired.
TP - TRAFFIC PROGRAM IDENTIFICATION: his service indica es wi h a signal
on he receiver display ha he program were receiving includes raffic news.
AF - ALTERNATIVE FREQUENCIES: i s he frequencies lis of differen
ransmi ers which ransmi he same program in he adjacen receiving areas.
The lis is memorized by he receiver and used o reduce he commu a ion ime
bee wen he differen ransmi ers of he same program.
TA - TRAFFIC-ANNOUNCEMENT IDENTIFICATION: i  used o indica e o he
car-driver ha he raffic news are on air. The receiver could use he signal in one
of he following modes:
a) To swi ch au oma ically from he Tape (or from he Compac Disk) o he radio;
b) To au oma ically swi ch on he radio when he raffic news begin;

c) To au oma ically change over from a s a ion which doesn ransmi raffic news;
M/S - MUSIC/SPEECH SWITCH: i s used o modify he music and he spoken
volume one by one.
PIN - PROGRAM- ITEM NUMBER: i s used o plan he receiver o receive cer ain
programs a preselec ed da e and hour.
RT - RADIOTEXT: i s used o ransmi he ex rasmission; his func ion is mainly
for he domes ic applica ion (house receivers).
EON - ENHANCED OTHER NETWORKS: i s used o ransmi he PI,PS,AF,PTY
o he PIN of o her radios.
TDC - TRANSPARENTE DATA CHANNEL: i s used for he da a ransmission
and i could be free used, for example, o send messages on a brighl ly sign.
IH - IN HOUSE APPLICATION: i s used o ransmi da a of exclusive use of he
broadcas er and i can be u ilized , for example, o send eleme ry da a, sof ware,

5.1 Introduction
This chap er describes he TRDS4001 ENCODER func ion . For u ili y, he device is
divided in subassemblies which will be deeply discussed in he following paragraph.
5.2 PowerSupply
The power supply sec ion is composed from a ransformer (115-125-230-250 V)
which supplies he vol ages of 11-0-11 V, af erwards hey are reduced from he power
supply o +5, +8 and -8 V necessary o feed he cards of analogic sec ion and digi al
logic, included on he RDS encoder.
The 24V inpu sec ion (now i is s andard), in case of mains absence, au oma ically
commu es he feeding on he ex ernal ba ery, herefore guaran eeing he con inui y
of he service.
5.3 RDSCircuit
I presen s a microchecker which manages he produc ion of RDS message. The
se ed RDS message is preserved also in absence of primary power supply.
The RDS carrier wave a 57 Khz is produced on locking a he 19 Khz one of MPX
signal in inpu for he s ereo ransmission sys ems, or wi h an in ernal quar z oscilla or
for he mono ransmission sys ems. In he s ereo sys ems he s ereo led ligh s. The

5) Check ha he range vol age which will supply he sys em is as desired.
6) Make a backup copy of he CD supplied wi h he equipmen before use i .
7) Do no open he rack con aining he sys em.
8) Clean he sys em only wi h a dry and sof clo h in order o avoid finishings
