720 Dynamic RDS Encoder
Información en español ---- > Clic AQUI
The 720 is our third-generation dynamic RadioData encoder for automatically parsing and scrolling song title and any other information on the faceplate of all RDS radios. The front-panel LCD displays setup parameters without the need for an on-site computer, and also shows incoming raw data from station automation as well as exactly what the listener sees on his radio. The 720 incorporates diagnostics and transmission safeguards for virtually foolproof installation and operation.
- Easy installation and setup
- Built-In diagnostics
- Unique no-headers mode scrolls song titles from unformatted satellite feeds
- Interfaces with all popular automation systems
- Setup and operating parameters without the need for a computer on site
- Scrolling messages are displayed exactly as seen by listeners
- LCD Display / Readout
- USB & RS-232 interface
- Supports European CENELEC and United States NRSC standards
- Works with any FM exciter and stereo generator
RDS APPLICATIONS SUPPORTED
- PI (Program Identification) 730 software automatically calculates PI codes for the US and Canada
- PS (Program Service Name) An 8-character station 'street name' or 128-character scrolling message (song info, promos, advertising, etc.)
- PTY (Program Type) Identifies your station’s format
- 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) 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
- AF (Alternative Frequencies) Up to 25 frequency entries for rebroadcast 'translators.'
- 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
Runs on any Windows® PC for either USB or serial (COM) port operation. The software is intuitive, self-guiding and contains numerous pop-up and other Help files.
- 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 appearsat 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.
A front-panel USB port gives quick and easy access for encoder setup. All static messaging may be quickly set with a laptop PC.
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.
105-130VAC and 210-260VAC; 50/60Hz; 20W.
