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

Specifications

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.
