Page 12: The Radio Data System Defined
THE RADIO DATA SYSTEM DEFINED The European Broadcasting Union (EBU) and its member coun- RDS: Europe vs. tries originated the concept of “Radio Data” transmission. The North America European RDS specification, CENELEC Standard EN50067, was (RDS vs. RBDS) first published in 1984, and was subsequently revised in 1986, 1990, 1991, 1992 and 1998. -
Page 13: The Rds Signal
The principal utility of this RDS function is with European radio networks and US stations with translators. The 732 can hold as many as 25 Al- ternative Frequencies. The Radio Data System is capable of set- Clock Time and Date: ting the date and time on RDS receivers equipped with a clock. -

This is a rather esoteric and little-used function; only monaural and conventional stereo transmissions are sup- ported by the 732 Encoder. This flag indicates whether music or Music/Speech Switch: speech is the primary programming. The purpose of this func- tion is not covered well in the respective Standards, so it comes as no surprise that it is not widely understood. -

Or he might simply leave the TA flag on inadvertently (or not!). The 732 Encoder incorporates a TA countdown timer that limits the traffic announcement to a user-programmed maximum number of seconds. -
Page 16: Section Ii - Installation
INSTALLATION GENERAL This section of the manual addresses the physical installation of the Model 732 encoder at its operating location; the ‘nuts and bolts’ of connecting the unit. This section also references pages where pertinent setup adjustments are discussed. As soon as the equipment is received, inspect carefully for any Unpacking and shipping damage. -
Page 17: Ac Mains Power
For all our sakes, please do keep these straight. RADIO FREQUENCY INTERFERENCE (RFI) Although it is expected that the Model 732 will be co-located Location with FM transmitters (and who knows what else!), do practice care and common sense in locating the unit away from abnor- mally high RF fields. - Page 18 Common Hookup Options – Model 732 RDS/RBDS Encoder — 16 —...

Page 19: Inputs, Outputs And Ports
The peak-to-peak level of the subcarrier at the RDS OUTPUT is adjustable from the front panel or through the Web interface. The adjustment range runs from zero to 3.7Vpp. When using this output, the 732 encoder serves as a unity-gain RDS+MPX buffer amplifier between the MPX/PILOT INPUT and the Output This finds utility in the ‘loop-through’... -
Page 20: Modem Link
A standard RJ-45 network jack is used to connect the Model Network Port 732 to a Local Area Network (LAN) or to the Internet. Net- working permits full remote setup and control plus SNMP functionality. Initial connection to a network is outlined in the next section. -

Some familiarity with the jog wheel knob and menu tree is encouraged, as you’ll need to gather certain information from the front panel before you can point your browser to the Web interface. -
Page 23: Menu Timeout
Web interface. GETTING UP AND RUNNING The 732 encoder comes with a printed ‘Quick-Start Guide’ (QSG) that helps you get the unit up and running in very short order, with encoder programming set for basic, ‘static’ RDS messag- ing. -

CT (Clock Time) RDS function, another supposed ‘convenience.’ A station sending CT information will set the clock in a listener’s radio to the correct local time. The 732 en- coder sets itself to Internet time to guarantee an accurate refer- ence. -
Page 28: Rds Messaging Delay
The PS field is usually populated automatically by station au- tomation. Section IV of this manual gives instructions for con- necting the 732 encoder with automation, and for formatting commands so that the function works properly. But even without a playout system you may manually program this field with a static PS message, be it your call letters or a simple identifying slogan to repeat over and over. -
Page 29: Dps Tags
RT+ ‘tags’ to display playout and other data in both the DPS and RT fields. Headers and tagging are detailed in Section IV. When Parse is set to Auto, the 732 encoder automatically ‘Parsing’ groups short words into 8-character blocks and breaks longer words to fit sequential frames. -
Page 30: Dps Defaults
For an explanation of RadioText Plus and RT+ ‘tagging,’ please refer to Section IV. DATA PORTS A very useful feature of the 732 encoder is the ability to see in- Command coming commands from station automation ‘on the fly,’ just as Debugging they are received. -

IP address (10.0.0.3) was the last device to address the encoder over the TCP 1: port. That port is currently shown Idle. Each 732 data port has its own screen area where specifics can Port Specifics be viewed and addressed. -
Page 32: No Headers' Operation
THE SCHEDULER The 732 encoder Scheduler lets the user select certain days, dates and times for special ‘events.’ Events can consist of text inserted into the PS and RT fields, and/or commands issued to modify encoder operation for certain timeframes. -
Page 33: Dps Not Updated
And… be sure that the Enable Scheduler: is set to On at the top. ALARMS The 732 encoder features alarms to warn of unusual operating conditions. Alarms show up on the OLED display on the front panel, as rear-panel ‘tally’ contact closures, and at the top of the Alarms submenu on the Web interface. -
Page 34: Rt Not Updated
DPS Not Updated alarm. The 732 encoder should always be sync’d to the 19kHz stereo Pilot Loss pilot. If pilot is lost the encoder automatically defaults to an internal time base for uninterrupted RDS service and messag- ing. -
Page 35: Setup (Subcarrier Level)
SETUP (SUBCARRIER LEVEL) This Web interface subhead is abbreviated somewhat from the corresponding front-panel OLED display due to small organiza- tional differences between the two menus. Nothing has been removed, however, and missing items should easily be found in the corresponding menu. Check the Front Panel Menu Tree in the Appendix. -
Page 36: General Purpose Inputs
Subcarrier In Phase Subcarrier In Quadrature The 732 Encoder is meticulously aligned at the factory to en- sure that the subcarrier has the proper phase relationship with the stereo pilot, whether the encoder is used in the sidechain or in the loop-through operating mode. -

You may change the default Host Name: from Host Name MODEL732 to personalize the equipment name, or to differen- tiate one encoder from another on the same network. -
Page 38: Accessing The Encoder Remotely
To ‘dial into’ the 732 encoder from the Internet, the unit must Accessing have a static IP address. If your router makes DHCP assign- the Encoder ments for other equipment on the network, simply assign the Remotely encoder a static IP that is outside the router’s DHCP range. -
Page 39: Snmp Operation
SNMP (Simple Network Management Protocol) allows other SNMP Overview TCP/UDP/IP equipment on the same Local Area Network (LAN) to communicate directly with the 732, and for the unit itself to initiate an alarm on the network. The 732 will interface directly with a network controller, tech- nically known as the SNMP ‘Manager.’... -

OTHER FRONT-PANEL SETTINGS These are settings specific to the front-panel OLED display and the jog wheel. The Admin/Display menu offers a Brightness choice for the OLED Display menu screen. You may change this from the 60% default value Settings to a higher or lower setting. We don’t recommend a much higher setting because this may shorten the life of the OLED graphic display module, and it doesn’t really look much bright-... -
Page 45: Section Iv - Addressing The Encoder
Section IV ADDRESSING THE ENCODER The 732 encoder is typically addressed by station automation to display artist and title info, station and program promotion, and perhaps even advertising. In this tutorial we will emulate the playout system with a ‘dumb terminal,’ using Telnet proto- col with the freeware terminal software utility, ‘PuTTY,’... -
Page 46: Using Headers
USING HEADERS Inovonics’ use of ‘headers’ dates back to the turn of the century and our first interactive RDS encoder. A header is nothing more than a command ‘identifier’ ahead of a message or other programming request. The encoder reads the header and either assigns the message to the proper display field or changes an encoder operational setting. -
Page 47: Using 'Tags
Similar header formatting applies to commands that change operating parameters of the 732 encoder. For example, we can adjust the RDS subcarrier output level to exactly 0.5Vpp by sending the Telnet command, RDSLEVEL=500 . -
Page 48: Rt+ Tags
A big advantage of tagging is that the 732 encoder then handles most of the message formatting, eliminating the need to figure out how to reformat text in the automation system and, in fact, eliminating the added headers completely. The 732 inspects the DPS and RT fields for any tags, and replaces the tags with the associated text. -
Page 49: Messaging Defaults
The 732 encoder will replace the bracketed item callouts with the actual song information text sent by station automation, us- ing the RT+ Commands described under the next heading. Bear in mind that this example was generated manually, so the en- coder will not have received actual title and artist text from the playout system. -
Page 50: Duration Command Exceptions
There are two exceptions to the DURATION= formatting rule. Duration Command Sending DURATION=0 will override the current DPS and Radio- Exceptions Text messages and replace them with the pre-programmed DPS Default and RT Default messages. These default messages will then continue to display until new commands are received. DURATION=1 is an alternative to entering a fixed message timeout value. -
Page 51: An Rt+ Command Example
The foregoing example illustrates how a command can be ab- breviated, but these commands can also be changed to conform to a playout system’s native command set. This set-it-once 732 utility would then obviate having to make multiple and ongoing changes in playout system syntax. - Page 52 With PuTTY emulating the station’s playout system, the left screenshot below shows transmission of title, artist and song duration, with an OK acknowledgement from the 732 encoder for each command. At the right is how these same data were received, as shown on the Data Ports / Debugging screen.
