RDS APPLICATIONS SUPPORTED

PS (Program Service Name) An 8-character station 'street name' or 128-character scrolling message (song info

promos

advertising

etc.)

PI (Program Identification) 730 software automatically
calculates PI codes for the US and Canada

PTY (Program Type) Identifies your station’s format

PTYN (Program Type Name) A further refinement of your type or style of programming

TP / TA (Traffic Program / Traffic Announcement) A utility that calls attention to critical traffic or other
emergency situations. Some RDS radios automatically retune to these announcements

even overriding CD or
MP3 playback

AF (Alternative Frequencies) Up to 25 frequency entries for rebroadcast 'translators.'

RT (RadioText) A 64-character block of plain-text messaging that can be called-up on the faceplate of some
RDS radios. RadioText is separate from

and in addition to

scrolling-PS messages

RT+ (RadioText Plus) An updated standard for song info display

CT (Clock Time and Date) The 730 sends timekeepingdata to RDS radios. The feature is set and updated
automatically with an Internet connection

DI (Decoder Information) The mono/stereo data flag

M/S (Music/Speech Switch) The mixed-music or speech-only data flag

RAW (Raw Data Entry) The 730 accepts ‘Free Format Group’ commands to facilitate custom RDS applications

SCHEDULER
Up to twenty

128-character scrolling-PS messages may be
programmed for transmission at specified times on prearranged
dates or recurring days of the week.

RDS DATA DELAY

Scrolling-PS

RT and RT+ message updates may be delayed in
1-second increments up to 60 seconds to match profanity and
transmission diversity delays.

MPX OR PILOT INPUT
An unbalanced

bridging (BNC) input accepts either the
composite/multiplex (MPX) signal (5V p-p

max.) or 19kHz TTLlevel
pilot sync from the stereo generator. The 730 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.

OPERATING MODES

Loop-Through (with relay-contact failsafe bypass):
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 only 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

RDS INJECTION LEVEL
Subcarrier level is adjustable from zero to 3V p-p

either from the
front panel or by remote software command. The LCD and
software screens show both bargraph and voltage readouts of
the subcarrier level.

FRONT-PANEL DATA ENTRY
The front-panel LCD and jog wheel allow on-site setup of all
operating parameters and messaging registers when a computer
is not available. The LCD is also able to show the values and
messages in all registers in addition to displaying incoming data
on the fly and the scrolling-PS message exactly as it is being
received by RDS radios.

USB PORT
A front-panel USB connector gives quick and easy access for
on-site encoder setup. All static messaging may be quickly set
with a laptop PC.

SERIAL DATA PORT
A rear-panel RS-232 connector (DB-9) accepts static encoder
programming and dynamic messaging from station automation.
The 730 accommodates all common data rates between 1200
and 115

200 baud. 730 software features an automatic port and
data rate ID utility to simplify initial connection and setup.

LAN (IP-NETWORK) PORT
A rear-panel Network connector (RJ-45) conforms to TCP/IP
networking protocols. Two TCP ports and one UDP port
are provided for remote access and connectivity from multiple sources

anywhere in the world.

TA SWITCHING
The temporary TA flag is set either by a software command or
with a contact closure through a rear-panel terminal strip. The
730 features a programmable TA-timeout utility to preclude TA
flag violations.

SUPPLIED SOFTWARE
Model 730 software runs on any Windows© PC for USB

serial
(COM) port and IP-network operation. The software is intuitive

self-guiding and contains numerous pop-up and other Help files.
