Updating the
AF List
To keep the 730 Encoder backward-compatible with earlier In-
ovonics models, the Alternative Frequency list (AF) may be en-
tered in either of two ways when using the Terminal utility.
1)
Enter the frequency directly in MHz. Example:
AF1=95.9
and
AF2=97.1
. Up to 25 Alternative frequencies may be
entered in this manner. To clear the second entry from the
AF list, for example, type
AF2=0
. The 730 Encoder will
re-sort the list, so AF ‘slot’ numbers may change.
2)
Enter the Alternative Frequency by direct entry of the
chan-
nel number
assignments listed in the RDS and RBDS Stan-
dards. Channel numbers are tabulated in the Appendix on
Page 81. An example entry would be
AF1=114
for
98.9MHz.
Sending the command:
AF0=0
will clear
all
AF entries from
the Encoder.
Saving to Non-
Volatile Memory
Most commands sent to the 730 Encoder as ASCII text strings
with headers using the Terminal utiltity are automatically saved
in non-volatile memory and will not be lost in the event of a
power interruption. Exceptions are DPS=, TEXT=, and RTP=
messages, which are considered temporary because they are
typically streamed from station automation and are continually
updated.
If, however, the Terminal utility is used to upload a scrolling-PS,
RadioText or RT+ message that needs to be retained, simply
type:
SAVE
to transfer these data from the encoder’s RAM to
non-volatile EEPROM memory.
Interrogating
the 730 Encoder
Typing:
HELP
, or simply:
(Enter), into the
Terminal window will bring up the menu shown
at the right. Because the 730 Encoder memory
contains a large number of messages and val-
ues, it has
been
di-
vided into four categories.
Typing:
1
will bring all the
setting for RDS messaging
into the window as shown
at the left. At the top of
the list you will see the
DPS=FLY ME TO THE
MOON
entry that you pre-
viously sent to the unit.
The other encoder register
entries will be explained
as they are addressed in
their respective discus-
sions.
