RT1EN
RT1 Enable
(0, 1)
Enables (1) or disables (0) the Radiotext 1.
RT1EN=1
Enables the RT1
RT2
Radiotext 2
Up to 64 characters long text message to be displayed on receiver in Radiotext format. Alternatively used in
conjunction with Messages Commands. Car radios usually don’t support this service, Dynamic PS can be
used instead.
RT2=Hello World
RT2EN
RT2 Enable
(0, 1)
Enables (1) or disables (0) the Radiotext 2.
RT2EN=1
Enables the RT2
RT2TYPE
Radiotext 2 Type (obsolete, use RTTYPE instead)
(A, B)
This command is obsolete and its support is no longer guaranteed.
RTPER
Radiotext Switching Period
(0-255)
Specifies the time in minutes between two switching of the Radiotext. The switching can occur between RT1
and RT2 or between messages specified for RT2 (command
RT2MSG=AUTO
).
RTPER=10
Sets the period to 10 min.
RTPER=0
Sets the period to 0.5 min.
RTTYPE
Radiotext Type
(0-2)
Specifies Radiotext type for RT1 and RT2
0 - A/A. Any Radiotext is always the same type.
1 - A/B. RT1 is always type A, RT2 is always type B.
2 - Automatic. Any change/update of the Radiotext causes the A/B flag to toggle. Default option. Required
for proper RT+ function.
If the receiver detects a change in the A/B flag, then the whole Radiotext display is usually cleared and the
newly received Radiotext message segments are written into the display. If the receiver detects no change
in the A/B flag, then the received text segments or characters are written into the existing displayed
message. Some receivers have two memory spaces for the Radiotext, one for type A and one for type B.
Then they display both messages consecutively in the loop.
RTTYPE=2
RSTDPS
Restart Dynamic PS
(0, 1)
1 – When the Dynamic PS text is changed and no Dynamic PS is running, it will start immediately.
0 – The
SPSPER
command drives the Dynamic PS start regardless of the fact that the Dynamic PS text
was changed.
Changing a Dynamic PS text (1 or 2) that is actually running will always cause its restart. This rule does
not apply to the
DPS1ENQ
command.
RSTDPS=1
SCRLSPD
Scrolling PS Speed
(0, 1)
Sets high (1) or low (0) speed of scrolling PS transmission. Although setting high speed gives the result
looking better, remember that on some receivers or under bad reception conditions the text may be
unreadable. The reason is absolutely outside the RDS encoder and comes out from the fact that scrolling
PS has never been included in RDS standard. Due to this the high speed is not recommended.
SCRLSPD=1
SPSPER
Static PS Period
(0-255)
Specifies the time between two repeats of the Dynamic PS text. Static PS (PS/TPS) is displayed during
this time. Increasing the value by 1 increases the period by approx. 2.7 seconds (exact value depends on
Group Sequence).
If value 255 is set, the Dynamic PS will be displayed only once if changed. RSTDPS parameter must be set
to 1 in this case.
If both DPS1 and DPS2 are enabled, the SPSPER cannot be zero (0).
SPSPER=4
Sets the period duration to about 11 seconds.
