720
RDS/RBDS Dynamic RadioData Encoder
AN RDS/RBDS ENCODER WITH
MULTIPLE MESSAGE-SCROLLING
MODES AND EASY, SELF-GUIDED
CONNECTION TO STATION
AUTOMATION.
Inovonics’ third-generation 720 incorporates a
number of important features to make installation
and operation simple, straightforward and safe.
The 720 automation command set remains
compatible with earlier models for seamless
integration alongside existing encoders.
The front-panel LCD screen allows the user to
scroll through and confirm all setup and operating
parameters without the need for a computer on
site. Incoming data from station automation can
be seen ‘on the fly,’ and scrolling messages are
displayed exactly as they are seen by listeners.
Intuitive software, built-in data diagnostics and
transmission safeguards make installation virtually
foolproof and help protect against accidental
misuse. The 720 supports European CENELEC
and United States NRSC standards.

Features and Specifications
• Accepts a serial connection for automation
data and features a front-panel USB port for
convenient local setup.
• A unique ‘no-header mode’ allows use with
unformatted, satellite-streamed song title
information.
• Works with any FM exciter and stereo generator.
RDS APPLICATIONS SUPPORTED
PI (Program Identification) A “digital signature” for your
station, based on call letters in the US and Canada or on
an authority-assigned identifier elsewhere. 720 software
automatically calculates PI codes for the US and Canada.
PS (Program Service Name) The station’s “street
name” that automatically appears on the receiver
faceplate in static-PS operation. This field scrolls song
titles or other messages in the dynamic-PS mode.
PTY (Program Type) An identifier for your station’s
format based on a list of pre-defined categories. Highend RDS radios can search for listening preferences.
TP (Traffic Program) A data flag identifying stations that
routinely include traffic bulletins in their programming.
TA (Travel Announcement) The TA data flag is
broadcast only during a critical traffic or other emergency
announcement. Some RDS radios automatically retune
to a station airing such announcements, and TA
broadcasts may even override CD or MP3 entertainment.
RT (RadioText) This is a 64-character block of plain text
messaging that can be scrolled on the faceplate of some
RDS radios. RadioText is separate from, and in addition to,
scrolling-PS messages.
AF (Alternative Frequencies) The 720 sends a list of up
to 25 frequencies for networks or stations with rebroadcast
‘translators.’ This allows RDS radios to seek the strongest
signal for a specific transmission.
DI (Decoder Information) An indication of whether the
broadcast is monaural or stereo.
M/S (Music/Speech Switch) A data flag to indicate
either music or speech-only programming.
RAW (Raw Data Entry) The 720 accepts certain Free
Format Group commands to transmit hidden data within
legitimate RDS groups.
SUPPLIED SOFTWARE
Runs on any Windows® PC for either USB or serial (COM)
port operation. The software is intuitive, self-guiding and
contains
numerous
and other Help files.

OPERATING MODES
Loop-Through: The RDS subcarrier is internally mixed
with the MPX input and the combined signal appears at
the encoder output at unity gain.
Sidechain: In this mode just the RDS subcarrier appears
at the encoder output. The monitored MPX or 19kHz sync
is only bridged to synchronize the 57kHz RDS subcarrier
with the stereo pilot.
PILOT OR MPX INPUT
An unbalanced, bridging (BNC) input accepts either the
composite/multiplex (MPX) signal or 19kHz TTL-level pilot
sync from the stereo generator. The 720 reverts to an
internal crystal timebase for monaural transmissions.
RDS OR MPX OUTPUT
An unbalanced, 75-ohm (BNC) output feeds a wideband
input of the FM exciter.
RDS INJECTION LEVEL
Subcarrier level is continuously adjustable from the front
panel from zero to 3V p-p. The LCD screen gives both
bargraph and voltage readouts.
SERIAL DATA PORT
A rear-panel RS-232 port (DB-9) accepts static encoder
programming and dynamic messaging from station
automation. The 720 accommodates all common data rates
between 1200 and 115,200 baud. 720 software features an
automatic port and data rate ID utility to simplify initial
connection and setup.
USB PORT
A front-panel USB port gives quick and easy access for
encoder setup. All static messaging may be quickly set with
a laptop PC.
TA SWITCHING
The temporary TA flag is set either by a software command
or with a contact closure through a rear-panel terminal strip.
A TA-timeout utility prevents TA flag violations.
POWER REQUIREMENTS
105-130VAC or 210-255VAC, 50/60Hz; 10W.
SIZE AND SHIPPING WEIGHT
13/4"H x 19"W x 8"D (1U); 9 lbs.
