Recognition of the RDS signal and its PI code (if any)
Setup functions
You access the configuration by pressing the jog dial on the right side of the display, the various
parameters are displayed in succession by turning the knob and the change is enabled by pressing
the jog dial in the mailorder parameter to change.
The parameters (sub-menus) are displayed in sequence:
STE SW
:
mode switching Stereo section
MPX SW
:
mode switching MPX section
STE DELAY to SUB
: Stereo section, delay time to switch from Main to Sub ( 0 - 255 sec)
STE DELAY to MAIN
: Stereo section, delay time to switch from Sub to Main (0 - 255 sec)
STE BLANK THR
: Stereo section, the threshold of switching level
MPX DELAY to SUB
: MPX section, delay time to switch from Main to Sub ( 0 - 255 sec)
MPX DELAY to MAIN
: MPX section, delay time to switch from Sub to Main (0 - 255 sec)
MPX BLANK THR
: MPX section, the threshold of switching level
MPX PILOT LEV
: MPX section,
Pilot signal level 19KHz reference
MPX RDS ALARM
: MPX section,
selection of type of alarm signal RDS
MATCH PI
: MPX section,
to edit and view the code PI reference
Description of the parameters
STE SW
;
pressing the jog dial at this menu enabling a change of mode switching section Stereo. In
succession, turning the knob, you see entries:
o
SUPER
: The priority input in the output is the MAIN, the level control signal is
applied on the MAIN, switching on the SUB can occur in case of lack of signal MAIN
or lowering of the level of the same below the threshold THR reference for a time
over one established. Restoring the MAIN signal input or its level above the threshold
THR, for the minimum time edited, the output will switch on the input MAIN. in this
mode is the primary external command applied via contact ST IN port Logic I / O
through which one can impose the switching input SUB regardless of the level of the
signal MAIN.
o
STUDI
: The input signal at the output is determined by the state of the contact ST
IN port Logic I / O, open contact = MAIN, SUB = closed contact. The control of the
signal level, in this case, is applied to the SUB, in case of no signal or less than the
predetermined threshold THR, the end of the observation time imposed, the output is
switched to the MAIN regardless of the state contact IN ST.
o
MAIN
; manual setting and fixed input MAIN output, control the level of the signal
shows the status of the alarm contact output port Logic I / O but does not cause
switching. In this mode, the switch from MAIN to SUB can not be activated using the
appropriate door contact Logic I / O.
o
SUB
; manual setting and fixed input SUB output, control the level of the signal
shows the status of the alarm contact output port Logic I / O but does not cause
switching. In this mode, the switching from SUB MAIN can not be activated using the
appropriate door contact Logic I / O.
MPX SW
; pressing the jog dial at this menu enabling a change of mode switching section MPX. In
succession, turning the knob, you see entries:
•
SUPER: the priority input output is the MAIN level control signal is applied on the MAIN
switch on the SUB can occur as a result of the following controls (if active):
