5.2.2

Data format

The P232U RDS encoder supports several formats (protocols) for input data and it’s designed to be compatible with all broadcast automation
software which allows direct RDS encoder control.

The support includes:

•  ASCII commands
•  UECP protocol (format given by UECP specification)
•  X-Command (described later in this chapter)

Basic data format for ASCII command is as follows:

Prefix (ASCII command): RT1=
Terminating character



: <CR> (Carriage return). <CR><LF> accepted as well.

Example:

RT1=Now Playing: Julia Michaels - Issues



See section 7 of the Technical manual for complete list of all ASCII commands.

5.2.3

Compatibility commands

To reach the best possible compatibility with broadcast automation systems, the P232U includes a special set of compatibility commands. In
the systems where the P232U is not directly supported (or the system is older version) the user may try to select another RDS encoder model
to send text messages. Where possible, set the communication as unidirectional.

Command

Translated to

TEXT=

RT1=

DPS=

DPS1=

PS_SCROLL=

DPS1ENQ=

5.2.4

Radiotext Plus (RT+ tagging)

The RT+ feature is designed to let the listener take additional benefit from the Radiotext service by enabling receivers to offer direct access to
specific elements of Radiotext. Typically the RT+ feature supports song artist and song title elements. These elements anyway carried in the
Radiotext, are identified by their class type, length and location within the Radiotext. The receiver must be equipped with the RT+ function (also
called "tagging") to take advantage of this feature.

The RDS encoder includes full support for the RT+ and its handling is highly automated. For direct use your broadcast automation system must
support X-Command or the RT+ function either by means of user defined groups or by the command

RTP=

. In other cases the Windows

control software used in the indirect link configuration can provide the RT+ service.

5.2.5

X-Command for RDS encoders

The X-Command is the newest and preferred method how to forward text information (incl. tagging) from the broadcast automation system to
the RDS encoder. It is based on simplified markup language. The X-Command is fully supported by the P232U RDS Encoder.

Example:

XCMD=<rds><item><dest>3</dest><text>Now Playing: <artist>Julia Michaels</artist> -
<title>Issues</title></text></item></rds>


