20 STL-SAT Changeover
© 2018 ITEL SNC
2.4.4 RDS Substitution(override) and Tunnel RDS-MPX
In the fourth Changeover submenu you can select the override mode of the incoming RDS signal, the
available modes are:
AfTables: only the alternative frequency tables are replaced, leaving the other contents of the
incoming RDS signal unaltered.
Full: the incoming RDS signal is suppressed and replaced completely with the internally
generated input signal.
Both modes are supported if the MPX channel, master or backup, is set to "FILT" mode.
STL RDS on SAT: By setting this flag a1, you can have the RDS stream received from the MPX input even
when the L / R channel is airing.
2.4.5 Dropouts Reconize
In the fifth changeover submenu, the parameters of the satellite dropouts are available:
HW Dropouts: By setting this flag to 1, it activates the dropouts detection on the GPIO input, the contacts
of this port relative to the DROPOUTS input must be connected to the SAT receiver status output, this
function requires a (Hardware) acknowledgment from the decoder sat.
During regular operation, then in the absence of dropouts detected by the SAT decoder the contacts must
be closed.
SW Drops sens: It allows you to choose three levels of sensitivity (minimum, average, maximum) in
software recognition made by the Dropouts Cahngeover DSP in the L / R audio inputs that come from the
SAT decoder.
2.4.6 PI Code Control
In the sixth Changeover submenu there are two extensive swap configuration flags:
Fast PI-Plt SW: if "1" is switched on and an exchange mode is entered that includes control of the PI code
and / or pilot tone level, causes immediate switching to the reserve channel if an unsuitable PI code is
detected and / or the tone is missing pilot.
Ignore REG PI: if activated "1", it will validate the incoming PI code and all its regional variants.
For example, having a PI 5252 internally programmed, 5452 or 5C52 will also be considered valid.
This flag should be programmed if you intend to use an exchange mode that includes the PI code control and
