ASCII instruction syntax
ASCII instruction description
FMB10 Encoder
Example(s) and comments
BYPASS=1
or
BYPASS=0
BYPASS=1 : the signal applied to the
"sync/mpx" input of the RDS encoder is
directly switched to the RDS output connector
The red "Warning" LED flashes once per
second.
Retransmission only occurs if the "jumper J1is
put in the signal retransmission position.
BYPASS=0 : the RDS signal appears on the
RDS connector. When the "jumper J2is
configured in signal retransmission mode, the
signal applied to the "sync/mpx" input is added
to the RDS output signal.
DATA=1
or
DATA=0
DATA=0inhibits the transmission of any RDS
data and sends only successive "0"s. This
transmission mode remains compatible with all
RDS detectors that will nevertheless detect
and announce the presence of a valid RDS
"signal".
This function permits an easier adjustment of
the RDS phase and level.
DATA=1transmit RDS normally.
The DATA parameter is always reset to 1on
power up of the RDS encoder and after being
set to 0 for more than 1 minute.
DI=v
v from
0 to 15
DI : Identification of the decoder to be used by
the radio.( Decoder Identifier)
The value of the DI parameter is coded in 4
bits, each bit b3, b2, b1, b0 represents one
information
b0=0 monophonic transmission
b0=1 stereophonic transmission
b1=0 no artificial head
b1=1 artificial head
b2=0 no compressed
b2=1 compressed stereophonic
b3=0 statis PTY
b3=1 PTY dynamique
Example :
DI=9 : stereo, non artificial head, no
compressed, dynamic PTY
ASCII mode: the DI parameter
can be reread with the command
DI?
Normally, set DI=1 when the
station transmits in stereo, set
DI=0 for mono.
The RDS receivers do not seem
to use this parameter.
