GRPSEQ Group Sequence
Defines the RDS group sequence. Allows the user to control the group order and adjust repetition rate of
individual RDS services. Max. 24 items are allowed. The services and groups are represented by following
symbols:
0 - Four groups 0A (MS, TA, DI, AF, one complete PS)
1 - Group 1A (ECC, LIC, PIN)
2 - Group 2A (RT)
A - Group 10A (PTYN)
E - Group 14A and 14B (EON)
X - Group from UDG1
Y - Group from UDG2 R
- Group 3A/11A (RT+)
Services, which are not placed in the sequence, are disabled regardless of their individual settings.
Services, which are placed in the sequence and are disabled by their individual settings, are ignored (skipped).
Inserting a nonsense string will result in the same effect as inserting a single 0.
Inserting an unknown symbol will cause ignoring the rest of the string.
It's a good practice to assure that at least one 0 is present in each consecutive 6 symbols. It is recommended not
to place more than 4 same symbols consecutively.
Take into consideration that RDS does not know anything like empty groups or delays between groups. There
must be still some groups sent to the output.
The GRPSEQ command does not affect: group 4A (CT), user groups inserted using the G command or UECP.
Four groups 0A followed by four groups 2A (very high Radiotext transmission rate),
other services are disabled.
Sets the groups sequence to default (022E1022EA022XYR).
High transmission rate of UDG2. PTYN and RT+ is disabled.
The RDS content is fully controlled via
Language Identification Code
Enables a broadcaster to indicate the spoken language he is currently transmitting.
LIC=00
Unknown/not applicable
If activated, any text incoming through the serial interface and followed by <Enter> will be automatically parsed
and will appear as Radiotext 1, Dynamic PS 1 or both. Control of other RDS services is not allowed until
deactivating the no header option.
To deactivate the no header communication, press the keyboard <Escape> key three times and then
press <Enter>. This sequence is equivalent to *NOHDR=0, which – of course – cannot be directly inserted.
See chapter 9 for more details.
*NOHDR=1
PIN
Program Item Number
The code in DD,HH,MM format should enable receivers and recorders designed to make use of this feature to
respond to the particular program item(s) that the user has preselected. Use is made of the scheduled
program time, to which is added the day of the month in order to avoid ambiguity.
PIN=12,16,40
Enables (1) or disables (0) the PIN service.
Specifies the program bank. RDS services in selected program bank are transmitted by the RDS encoder and
can be modified and stored into EEPROM memory. If Program is set to zero (0), most of store operations are
not allowed to protect the data (since the destination into EEPROM is undefined in general).
1 - Program 1 is selected (default)
2 - Program 2 is selected
0 - External program switch selects the program
PROGRAM=1
