To enable the PI mis-
match function, enter
the station’s true PI
code in the PI Code:
box. The code being received at the moment is shown as the
Current PI: , and if that’s for-sure your station simply enter that
same hex value and click
Save
.
There are no threshold settings for RDS alarms, and both RDS
loss and PI mismatch share the same Time On (Sec): and Time Off
(Sec): settings that work the same way as alarms already dis-
cussed.
RDS RadioText
Not Updated
When a playout system ‘sticks’ while sending RDS RadioText, it
can cause problems… not only the display of RadioText, but
the attendant RT+ functions as well.
Turn the RDS RadioText Not Updated Alarm: On and set a Time On
(Min): at a nominal figure of 20 minutes or so to alert personnel
to a ‘stuck’ RadioText field.
RDS CT Out
of Range
This alarm function compares local Internet time with the
transmitted RDS time, which is used to set listeners’ car radio
clocks. Rather than absolute, to-the-second accuracy calibra-
tion, this is more a safeguard against transmitting a false hour
figure and really confusing your listeners.
If the tuned station is not sending RDS time, then
RDS Time: In-
valid will show below Unit Time: . The Threshold On (Min): lets you
set a ‘margin of error’ between
Unit Time:
and
RDS Time:
. If these
times disagree by more than a minute or two, you might check
to see where your RDS encoder is getting its updates.
The RDS Clock Time (CT) feature compares the off-air RDS time
with the 541 system time, assuming of course that the 541 has
been set-up properly and is receiving Internet time updates
(Pages 44-45). Internet (
Unit Time:
) shows at the top of the
screen.
There is only a
Threshold On (Min): setting, the alarm simply
triggers (or resets) when the mismatch exceeds (or falls back
below) the set number of offset minutes.
RDS TMC Not
Received
The Traffic Message Channel provides traffic congestion up-
dates to GPS navigation systems in the vicinity of the host FM
station. Information is updated constantly, so RDS 8A group
activity falling below expected usage can be used to trigger an
alarm.
The grayed-out
TMC
Groups (%): indicator
shows the current lev-
el of activity, which in
practice can easily
reach the 25% pegged-
out maximum. Based
