1. Introduction
1.1 Main Highlights
• The RDS encoder is made with full digital technology capable to generating a
very high quality of modulation and of spectral purity.
• It supports all popular services including TMC, TDC, IH and EWS.
• The card can be programmed using any UECP SPB490 compatible software.
• The programming software is also supplied, obviously compatible with SPB490,
capable to managing all the functions and services available on the hardware
in addition to the personalized management of PS messages.
• The card is equipped with at least two serial ports, which can be used
respectively for programming and for dynamic data (e.g. TMC data).
• The rmware can be updated via serial port without the need of hardware
settings and without service interruption.
1.2 RDS System Description
The Radio-Data-System is proper for the transmission of information in mono/
stereo programs of VHF/FM (87.5-108 Mhz).
Itsatisestherequestedrequirementstothetransmissionofsupplementarydata
on radio programs:
1) Compatibility with the current mono/stereo transmissions;
2) Absence of interferences towards the adjacent programs;
3)Compatibilitywithotheridenticationsystemswhicharealreadyworking.
The system, selected by an international specialistic team, allows the data
transmission at a speed of 1187.5 bit/sec with phase modulation at two levels ,
carrier wave 57 Mhz and range ±2 Khz.
Thebroadcastedbinarysignalisinadvanceputoutonadi󰀨erentialcodication.
Theregistryoftransmissionisatpackagesoflenght104bits(87.6ms)named
GROUPS,eachofthemcomposedof4blocksof26bits.
Everyblockiscomposedof16bitsofinformationandof10bitsofprotection,which
are properly studied to allow the recovery of an erroneous word with a maximum
of 5 wrong bits.
Theyareprovidedwith16separeteblocksofwhich6arestillnotdened;every
group begins with a PI identication code  (Program Identication) which has
the double intent to synchronize the receiver and to identify the channel which
transmits the signal.

The pourpose of the /RDS-TFT2HE, /RDS-TFT3HE & /RDS-TFT4HE option is to
managetheprincipalservicesdenedbythestandardCENELECEN50067as:
PI, PS, PTY, TP, AF, TA, DI, M/S, PIN, RT, EON, TDC, IH, CT.
As follows, we’ll mention a short description about the function of each of these
services.
PI - PROGRAM IDENTIFICATION:it’stheidenticationcodeoftheradio.Itsmore
important application is to allow the receiver, in case of bad reception, to implement
the “Automatic Frequency Change”; this happens when there is a signal with the
same PI and of better level than the syntonized one.
PS - PROGRAM SERVICE: it’s the visualized text on the receiver display, which
has to be of maximum 8 characters, as this is the standard dimension of receivers
displays.
The /RDS-TFT2HE, /RDS-TFT3HE & /RDS-TFT4HE characteristic is to store up
to 8 messages and the time of transmission of each of them. Every message can
be composed from 1 to 16 words of 8 characters, and it’s possible to select the
permanence time on the display of each of the 16 separate words.
PTY - PROGRAM TYPE: it’s the identication of the “ProgramType” which is
onair(exampleNews,Sport,Rock,etc.)It’susedtoqualifyonthereceiverthe
automatical research of the program type desired.
TP - TRAFFIC PROGRAM IDENTIFICATION: this service indicates with a signal
onthereceiverdisplaythattheprogramwe’rereceivingincludestra󰀩cnews.
AF - ALTERNATIVE FREQUENCIES: it’s the frequencies list of different
transmitters which transmit the same program in the adjacent receiving areas.
The list is memorized by the receiver and used to reduce the commutation time
beetwenthedi󰀨erenttransmittersofthesameprogram.
TA - TRAFFIC-ANNOUNCEMENT IDENTIFICATION: it’ used to indicate to the
car-driverthatthetra󰀩cnewsareonair.Thereceivercouldusethesignalinone
of the following modes:
a) ToswitchautomaticallyfromtheTape(orfromtheCompactDisk)totheradio;
b) Toautomaticallyswitchontheradiowhenthetra󰀩cnewsbegin;
c) Toautomaticallychangeoverfromastationwhichdoesn’ttransmittra󰀩cnews.
M/S-MUSIC/SPEECHSWITCH: it’s used to modify, in the receiver, the music
andthespokenequalizationonebyone.
PIN - PROGRAM- ITEM NUMBER: it’s used to plan the receiver to receive certain
programs at preselected date and hour.
RT - RADIOTEXT: it’s used to transmit the text trasmission; this function is mainly
for the domestic application (house receivers).

EON-ENHANCEDOTHERNETWORKS: it’s used to transmit the PI,PS,AF,PTY
to the PIN of other radios.
TDC - TRANSPARENT DATA CHANNEL: it’s used for the data transmission and
it could be free used, for example, to send messages on a brighltly sign.
IH - IN HOUSE APPLICATION: it’s used to transmit data of exclusive use of the
broadcaster and it can be utilized , for example, to send telemetry data, software,
etc...

a maximum of 25 alternative frequencies; every message automatically starts at
thehourofthedayspecicatelypreselectedfromtheuser.Moreover,itallowsto
manage all the services, which are listed in the foregoing section.
All the /RDS-TFT2HE, /RDS-TFT3HE & /RDS-TFT4HE option management
applicationsarecongurablewithaIBM-compatiblePersonalComputer,which
has to be connected by RS232 serial cable to I2C BUS or SERVICE/RDS input
(depending on model).
After programming, disconnect the RS232 data cable and then reconnect the
custom cable to the I2C BUS or SERVICE/RDS input.
The software and the new version can be downloaded directly from RVR web site.

 5. WINRDS+SoftwareIntroduction
 5.1 WINRDS+Application
WINRDS+isanapplicationbasedondocuments,eachdocument(le)represents
a RDS system and contains all information relating to it.
You can open multiple documents and communicate with several devices
simultaneously,providedthateachworkstowardsadi󰀨erentserial,oryoucan
have multiple devices on same serial port, provided that only one at a time is
allowed to send. If you try to transfer data towards two devices, on the same serial,
thesecondwindowwillnotconnectwhiletherstwillattempttocongureboth
devices,creatingconicts.
The application communicates in UDP from version 1.X.2.0, towards a selected
address in the “Communication-> RS232” (IP + PORT) POP-UP. Only one of the
open windows can use UDP communication instead of RS232 communication.
 5.2 RDSDevices
This section contains information on how RDS is structured.
The data contained in DNS ACTIVE is continuously transmits from each device.
To activate the DNS see special section “Enabling DNS-PSN”.
Each DNS contains the MAIN_PSN or PSN-1 all RADIO’s data that is transmitting,
PI and PS are required in these data otherwise the radio receiver can not use the
RDS data. In addition to the PSN-1 are available 7 other PSN called “EON-1 …
EON-7” that user can decide to enable and use if it has the “Friends Radio” on
which move the tuning when the radio signal becomes too low.
In addition, each DNS contains one or more lists of alternative frequencies that
are used to tune the car radio when you move from an area covered by a frequency
toanother.Alsoforfriendsbroadcastersispossibletodenepairsoffrequencies
that enable the radio receiver to change tuning.
EachDNScontainsabu󰀨erthatcanaccommodateupto16messageof“Radio
Text” , each long up to 64 characters that can be read by radio enabled (typically
likesxedreceivers,andnotbythecarradio).
Theuserswhowishtohavedi󰀨erentdataduringspecictimesofdaycanenable
the time management of DNS by loading data from other DNS enabled up to a
maximum of 5 or 6 DNS depending on apparatus. The devices based on BIOS
TRAxxxx have 6 DNS while other units have only 5 DNS.

The users who need to see motion written on the car radio must use the window
“PS Messages” that allows to have up to 8 sliding messages each long up to 128
characters or compound from 2 to 16 PS that rotating with personalized times.
These messages, if enabled, are transmitted instead of PS within the PSN and
do not depend on DNS enabled.

The “UART communication Setting” section allows you to choose the PC serial
port used to communicate with the devices and the speed communication from
1200 to 115200. The “Automatic” selection forces the program to groped all

The “URL settings UDP” section is used to select the “IP” address and the port to
which send UDP messages and receive replies. Please note that this connection
is no connection so you can send messages from multiple applications at once
