3.9.4 REPORTE TÉCNICO de transmisión
The option "DOWNLOAD FULL TEST" runs all the mea-
surements and dumps the results in a text file, which
also includes the values from the FM Analyzer. The file is
saved in the default download folder of the web browser.
This report can be requested for technical support.
Note that if the tuner is off, no measurements or reports
can be generated. To turn on the tuner, press the “ON /
OFF” icon and wait a few moments for the values to sta-
bilize. Then generate the report.
The measurements will introduce brief interrup-
tions to the on-air signal.
3.10 RDS
542APC has an internal RDS encoder. RDS (Radio Data
System) is a system developed by the European Broad-
casting Union (EBU). It allows adding additional informa-
tion to a conventional FM signal, by including a data
channel. Its main applications include:
1. The automatic tuning of a receiver to a radio network
selected by the user. This allows the user to listen to
the same program during a long trip by route, without
having to manually tune the receiver to another trans-
mitter of the same network, when the reception be-
comes deficient when leaving the area of coverage of
a radio station.
2. The display on the screen of the receiver of the name
of the station tuned, for example "Radio One", and the
type of content that is receiving: news, magazine,
sports, musical, varieties, religious, etc.
3. Automatic receipt of information related to traffic.
When this feature is selected, news is prioritized over
traffic, so that the receiver will automatically switch,
within a same station chain, to the station that trans-
mits information about the traffic, and once the infor-
mation is completed, Tuner will return to the previ-
ously tuned station.
3.10.1 RDS basic settings
The configuration and control of the RDS is carried out by
IP through the ETHERNET port of the 542APC (see 11 in
Figure 1).
The basic RDS parameters can be defined from the WEB
control interface of the 542, accessing the FM OUTPUT
option in the menu shows a block diagram with the RDS
and access to its configuration.
TCP RDS PORT
Defines the TCP port to receive communication from the
RDS software. The default TCP port is 9762. To modify it,
enter the new value and press APPLY.
To control the RDS encoder, the Solidyne-Magic RDS
software (see below) or the "Solidyne Audicom" broad-
cast management software must be installed on the PC.
Default PS (Program Service)
It is a fixed text, usually the name of the station. It is dis-
played on RDS receivers in order to inform the listener
which program service is being broadcast by the tuned
station. The RDS standard allows a maximum length of 8
characters.
PI (Program Identification)
It is used to identify a network of stations or repeaters of
the same radio network, so that the receiver automati-
cally switches from one station to another on the net-
work, depending on the quality of reception. It is a four-
digit hexadecimal number (0000 to FFFF).
Program Type
Identify the type of content broadcast.
M / S
Identify whether the content being broadcast is music or
words.
TA State (Traffic Announcement)
On / off identifier to indicate when a traffic announce-
ment is on the air. It can be controlled manually from the
button, or remotely via GPI.
Traffic PS
It is shown in place of the PS field when the Traffic An-
nouncement flag is active. If you do not need to use the
Traffic PS, leave this field empty.
DYN PS
The Dynamic PS field is implemented using the normal
PS field and sequentially replacing the information. Thus,
text messages of up to 64 characters are supported,
which will be displayed instead of the fixed PS field. The
text scrolls horizontally with a speed determined by the
Scroll value.
DYN PS is used for commercials, news and broadcast
texts (title and artist of songs).
