3.1.1. To connect the FMB10 encoder to the transmission installation : “loop through”
¾The FMB10 encoder is inserted between the Stereophonic encoder and the transmitter (pilot): this is
the most frequent set up.
¾The synchronisation of the RDS encoder is done by extracting the 19 KHz pilot signal contained in the
signal supplied by the stereophonic encoder to the RDS encoder "sync/mpx" input.
IMPORTANT: in this configuration, place "J1" and "J2" of the FMB10 PCB so as to ensure the retransmission,
of the composite 'multiplex' signal applied to the input of the RDS encoder in all cases.

3.1.2. To connect the FMB10 encoder to a RDS or SCA input of the pilot transmitter : side chain
¾This configuration is less common but more "professional". It uses the input of the FM pilot provided for
this reason.
The synchronisation of the RDS encoder is done by applying a 19 KHz clock (usually available at an
auxiliary output of the stereophonic encoder) to the RDS encoder "sync/mpx" input.
If no 19 KHz signal is available on the stereo encoder output, apply the multiplex signal directly to the
"sync/mpx" input of the RDS encoder.
¾It is advised, in this set up to configure "J1" and "J2" of the RDS Silver Encoder PCB to inhibit the "BYPASS"
function in all cases.

4.3 Function details
4.3.1 Main window
This consists of a zone displaying the encoder’s main parameters and the command buttons.
Active button wording appears in dark red:
When the mouse’s cursor goes over an active button, its wording appears in bright red:
When a function is disabled or inaccessible, the corresponding button appears in grey:
When the mouse cursor stays above a button or a display parameter zone, an explanation message is
displayed.
4.3.1.1 Description of display
The upper part of the main window is occupied by a display zone which reproduces an LCD type of displayer.
The central part is reserved for alpha-numerical indications:
•PS (Programme Service name): this is the name of the received program, displayed on all
RDS receivers. This zone also displays the Dynamic PS when this functionality is active (see
paragraph ). This zone has 8 characters.
•RT (Radio text): a text message of a maximum of 64 characters destined for receivers
equipped with an appropriate displayer (usually home receivers). This zone has 16 characters.
When this information is dynamic (Dynamic PS, Radio text), the display is a simulation of RDS data transmitted
by the encoder (timing, groups of characters …). It is not, in any way, a question of an acquisition of actual

encoder transmitted data: especially, the object is not to try to check synchronism with the display obtained on
an RDS signal analyser in real time.
Right and left parts of the displayer are used to present static or temporary parameters. From top to bottom and
from left to right can be found the following:
: PI code display zone (Program Identification) being broadcast.
:PTY code display zone (Program Type). When the mouse cursor stops for a moment
on this zone, code signification is indicated on light background. If a PTYN (Program TYpe name) has
been configured, its contents are displayed following the PTY.
: Current state of control signals of Info Trafic system (Traffic Programme, Traffic
Announcement). Dark text on light background indicates a value of 0(here TA), and, vice versa, light
text on dark background indicates a value of 1(here TP).
: State of MS communication code (Music / Speech).
: State of bit 0 (Mono/Stereo) of DI code (Decoder Identification).
: State of encoder output: indicates if an RDS signal is in fact present at encoder output (signal’s
Stop/Start parameter, see paragraph 4.3.2). Dark background indicates the presence of an output
signal.
: State of connection with the encoder. Dark background indicates that the connection has been
established and that any parameter modification will be transmitted to the encoder.
: Current encoder communication indicator when background is dark. This indication is
momentary.
4.3.1.2. Description of buttons
The lower part of the window contains a series of buttons for currently operating the encoder: one click on one
of these buttons (excepting TA) will display a window enabling corresponding parameter(s) to be modified.
These windows have 2 buttons: the Send button enables the encoder to be programmed with the considered
parameter’s new value; the Close button enables the window to be automatically closed again.
From left to right:
: enables station identification parameters to be toggled (PI + PS) between the two actions
maintained by the encoder.
: enables the Dynamic PS text to be modified (See  for more details on this functionality).
: enables both the transmitted PTY code and the PTYN message text to be modified.
: enables the Radio text message to be modified. If the Radiotext is stopped, this button is
not active (cf 4.3.2 Radiotext).enables the Radio text message text to be modified.
