Setting Basic RDS Data
Before getting on-air with the RDS signal, you will need to decide on the settings to be used. The following RDS services must be set as the
first. Use the Windows control software and its GUI. For more experienced users or those without a Windows PC, any terminal programme or
integrated web site can be used as well.
4.4.1
PI (Program Identification)
Tip: The RT 25-2 RDS control software includes a wizard that calculates the PI automatically.
This is very important information that enables the receiver to distinguish between countries, areas in which the same program is transmitted,
and the identification of the program itself. The code is not intended for direct display and is assigned to each individual radio program, to
enable it to be distinguished from all other programs.
The PI code consists of four characters (hexadecimal numbers).
The first character identifies the country:
0
Cannot be assigned.
8
PS, BG, LV, PT
1
DE, GR, MA, IE, MD
9
AL, DK, LI, LB, SI
2
DZ, CY, CZ, TR, EE
A
AT, GI, IS
3
AD, SM, PL, MK
B
HU, IQ, MC, HR
4
IL,CH, VA
C
MT, GB, LT
5
IT, JO, SK
D
DE, LY, YU
6
BE, FI, SY, UA
E
RO, ES, SE
7
RU, LU, TN, NL
F
EG, FR, NO, BY, BA
The second character identifies the program type in terms of area coverage:
0
Local
Local program transmitted via a single transmitter only during the whole transmitting time.
1
International
The same program is also transmitted in other countries.
2
National
The same program is transmitted throughout the country.
3
Supra-regional
The same program is transmitted throughout a large part of the country.
4 to F
Regional
The program is available only in one location or region over one or more frequencies, and there
exists no definition of its frontiers.
The third and fourth characters are used to clearly identify different stations within the area of coverage.
Important note: Meaning of some PI digits may be different for US RBDS.
Important note: If the station has only one transmitter, second PI digit must be zero (x0xx).
Important note: Factory default PI value is FFFF and it's needed to change it as soon as possible to avoid the situation that two different
stations with common area of coverage have the same PI. For each station in the same location the unique PI must be assigned. Stations that
carry different program must be unambiguously identified by the last two PI digits. In other case they are recognized as one station by car
radios, regardless of any other service settings. If the broadcaster hasn't received the 4-digit PI from regulatory office, he must choose such
number that is not in conflict with other stations in the location.
4.4.2
PS (Program Service name)
The PS name is max. 8 character long radio station name that will be shown most of the time on the radio display. Advanced use of the PS
(Dynamic/Scrolling PS) is discussed in Technical Manual or Windows software Help.
4.4.3
PTY (Program Type)
The PTY code defines the type of the programme broadcast within 31 possibilities. See chapter 12.2 of the Technical Manual for a complete
list. This code could be used for search tuning.
Important note: PTY number 1 (News) should never be left on all the time. Use PTY number 3 (Info) for this purpose.
