Loop:
Determines the time between two loops of the Dy-
namic PS text. During this time the text Static PS is dis-
played.
Scroll:
Sets the high or low scroll speed of the PS
stream. High speed does not work on some receivers, es-
pecially cars, or with poor reception conditions. The rea-
son is not related to the RDS encoder and is due to the
fact that the horizontal offset of the PS has never been
included in the RDS standard. Because of this, high
speed is not recommended.
The use of the Dynamic-PS field is restricted in some
countries and is not an implementation of the RDS stan-
dard. The manufacturer is not responsible for the mis-
use of this functionality. Some receivers may not cor-
rectly display the Dynamic / scrolling PS field due to
characteristics of the receiver
3.10.2 Advanced settings - Magic RDS
To configure and control the 542’s RDS, download and in-
stall the software “Magic RDS” from the following link:
Magic RDS runs over Windows and access to the
542APC via IP through the ETHERNET port
-
11
connec-
tion
.
A LAN terminal is used to transmit data to the
542APC RDS encoder. The data can be static texts
stored in the 542APC; or texts can changes dynamically,
for example announcing the songs names. Dynamic text
requires permanent TCP/IP access to the 542APC.
If the station has the Solidyne Audicom broadcast man-
agement system, it is not necessary to use MagicRDS
for dynamic updating of the broadcast titles. Communi-
cation is direct between Audicom and the processor
over the LAN. For more details see the Audicom docu-
mentation.
1. Once downloaded, install and run
Magic RDS
.
2. Go to
Options
→
Preferences
3. At
Preferences
choose the tab
General.
4. Change
Connection type
to
“Ethernet TCP/IP”
.
5. In the field
Port
enter the TCP value that was de-
fined at the 542APC. Default is 9762. The TCP
for 542APC is set using the Control WEB panel,
in the option “System" (see
“3.4.13 System set-
tings”
).
6. In the field
Host
enter the 542’s
IP
. By default
the unit comes with dynamic IP enabled. The IP
shows on the OLED screen at the frontal panel.
To use RDS with dynamic text, that updates in
real time (i.e. to show the song names) set the
542 with a fixed IP.
When the processor is connected to another network
away from the studio, the RDS data can be sent over the
Internet. The ISP must provide a fixed IP address on the
remote LAN. This IP address is entered into MagicRDS
or Audicom RDS.
The remote LAN must be configured to redirect incom-
ing packets through port 80 to the local IP address as-
signed to the 542APC (port forwarding), and also redi-
rect packets using port 9762 (or another port config-
ured in the RDS software).
7. The name of the radio station enters in the field
“Default PS” on the Magic RDS main screen.
8. Take in mind to change the default value of “PI”
(Program Identification) to avoid conflicts with
near broadcasters. Default value is FFFF (hexa-
decimal).
For more details about setting and use of RDS, please
refers to the documentations included with Magic RDS.
3.10.3 Connecting the RDS to transmitter
542APC does not require a RDS connection. The MPX
signal contains the RDS information, which is injected di-
rectly to the transmitter when the MPX output is con-
nected.
The digital signal containing RDS information is transmit-
ted at a rate of 1187.5 bit / s and modulates to a 57KHz
sub-carrier, using amplitude modulation with suppressed
carrier. This is added to the stereo multiplex signal that
is sent to the input of the transmitter.
