713 - Dynamic RDS/RBDS Encoder

THIS PRODUCT IS NO LONGER IN PRODUCTION

The model 713 incorporates all the features of our field-proven Model 712, but additionally gives dynamic, on-the-fly programming access via a local network (or even the Internet!) with its built-in TCP/IP interface. This connectivity permits full integration of RDS/RBDS transmissions with the station’s other networked functions, including message streams for digital radio and Webcasting.

Front-panel USB access further simplifies programming of all static RDS/RBDS information. The Inovonics 713 is a full-function encoder with features and performance that match or exceed those of European design.

Features


  • Connects to station automation with RS-232 serial interface or via LAN/Internet

  • Sends dynamic messaging in "block" or "safe scrolling" modes

  • Transmits all service flags, including TA override

Standards Supported

European CENELEC and United States NRSC

RDS Applications Supported

  • PI (Program Identification) A “digital signature” for your station derived from call letters in the US, or assigned by an appropriate authority in other countries.
  • PS (Program Service Name) The “street name” of your station that automatically appears on the receiver faceplate when scrolling-PS messaging is not enabled. PTY (Program Type) This identifies your station format from a list of pre-defined categories to help listeners find their preference quickly.
  • TP (Traffic Program) This data flag identifies stations that include traffic bulletins as a routine part of their programming.
  • TA (Travel Announcement) A TA data flag is broadcast only during a critical traffic announcement. High-end RDS radios automatically retune to a station airing such an announcement, even interrupting CD or satellite sources.
  • RT (RadioText) This is a 64-character block of plain text messaging that can be scrolled on the faceplate of RDS radios equipped with an INFO or DATA button. RadioText is independent from scrolling-PS messages and may be sent concurrently.
  • AF (Alternative Frequencies) The encoder maintains a list of stations on a network or with rebroadcast translators. This allows radios to seek the strongest signal for a specific transmission.

  • DI (Decoder Information) Indicates whether the broadcast is monaural or one of several binaural, stereo or surround-sound options.
  • M/S (Music/Speech Switch) A data flag to indicate music or all-voice programming.
  • FFG (Free Format Groups) The 713 can accept bit-by-bit programming to transmit hidden data within the RDS stream. Used for telemetry or for proprietary communications.

Loop-Through Mode

The encoder internally combines the RDS subcarrier with the composite/MPX input, which appears at the encoder output at unity gain.

Sidechain Mode

Only the RDS subcarrier appears at the encoder output. It is subsequently combined with the composite/MPX program signal at the FM exciter.

Pilot or MPX Input

Unbalanced, bridging BNC; accepts either a sample of the composite/MPX signal or 19kHz TTL-level sync from the stereo generator. Operation reverts to an internal crystal timebase for monaural transmissions.

RDS or MPX Output

An unbalanced, 75-ohm BNC output to feed the wideband input of an FM exciter. The RDS subcarrier is continuously adjustable between zero and 2 volts p-p.

USB Port

Front-panel access for rapid local programming of static data.

Serial Port

An RS-232 rear-panel DB9 connector that can connect directly to station automation for dynamic messaging; 2400 –115,200 baud.

Network Port

An RJ-45 ‘Ethernet’ connection for TCP/IP programming of all encoder functions over a network or the Internet.

TA Switching

The temporary TA flag is set either by a software command or with a momentary contact closure through a rear-panel terminal strip.

Power Requirement

105 –130VAC or 210–255VAC, 50/60Hz; 10W

Size and Weight

13/4”H x 19”W x 7”D (1U); 8 lbs.
