RDS Encoder User Manual Rev 2.2 External control port status and enabling: Ext port enab.: OFF TA: OFF MS:OFF SP:MUS In the upper row, the external control port status is shown. To remotely control the TA and M/S flags with external devices (eg. your radio automation system), it is necessary to enable the external port. Note: when the external control port is enabled, it will not be possible to control these flags through the Rd‐Link software. The lower row shows the input status in real time and it is useful, during the installation process, to verify the correct connection of the external devices. Encoder synchronization window: VCXO [ ] |||||||||||| 19K Ref: INT On the encoders provided with external synchronization input, the synchronization window is available and it allows the selection of internal or external reference and the operating status. During normal operation, both with internal or external reference, the bar should be about half scale. If the bar reach extreme values, it means that the synchronization signal has a tolerance greater than +/‐ 2Hz. Note: If the encoder is used with monophonic signals, the reference must be set on INTERNAL. With a stereo signal, you must enable the external reference. On Hw>3.0 the pilot reference, as a default setting, is extracted from the incoming MPX signal. If a separated clock sync is needed, the internal jumper J1 has to be set to "BNC" position and a 19KHz clock signal has to be injected into "PILOT SYNC" connector. ...

RDS Encoder User Manual Rev 2.2 PI:Program Identification Identification code of the station. The code consists of 4 digits, the first digit indicates the country of origin, the second represents the area of coverage and the last two identify the station into its coverage area. First digit, the country of origin of the program. You may write it directly into the “PI Code” editbox or select it using the “Country” dropdown list. A list of some country codes is reported in appendix A. For the second, according to the coverage area, choose one of the following codes: 0 Local coverage, the station has only one frequency 1 International 2 National 3 Supra‐regional 4..F Regional Note: the coverage code “0” is intended for stations having just one frequency. If used erroneously, it might lead some receivers to ignore the AF lists. The two last digits uniquely identify the station into its coverage area and shall be different amongst all other stations transmitting on the same area. Some examples: 5001: Italian radio station (5) local coverage (0), program code 01 5202: Italian radio station (5) national coverage (2), ...

If disabled, only 0A groups will be trasmitted. CLIPPER ON: If the RDS coder has the audio input card, it will turn the clipping function on to cut out all peaks exceeding +/‐ 75KHz deviation. PREEMPHASIS ON: If the RDS coder has the audio input card, it will turn on the preemphasis. Ensure that the audio input signal has not been already preemphasized. STATION ID: This 16‐chars string can be assigned to the coder for its identification. It could be its destination, the site to which the encoder is assigned, or the name of the radio which owns it. It will not be shown anywhere else, neither transmitted into any RDS block; it is just a label to identify the coder. 15 ...

RDS Encoder User Manual Rev 2.2 Alternative frequencies The RDS encoder allows method "A" or "B" for transmitting alternative frequencies. The choice between the two methods depends on the structure of the network and the number of alternative frequencies. There is no flag that indicates to the receiver if the alternative frequencies are transmitted by method "A" or "B"; the difference between the two methods is just on how the lists are compiled. Note: It is not possible to compile different lists using the A and B simultaneously. “A” method should be used only when the network has a maximum of 25 frequencies and does not differentiate regional programming. “B” method is used when the alternative frequencies are more than 25 or when, within the same network, there is a program differentiation, such as local news or advertising, only on certain frequencies. The lists must be compiled starting from the first and should be filled leaving no empty lists in between: lists after any empty list will not be transmitted. 18 ...

RDS Encoder User Manual Rev 2.2 METHOD “A”: This is the simplest method and it is indicated for all those stations which have a maximum of 25 alternative frequencies and do not broadcast regional programming. To implement this method, simply insert in AF List 1 all frequencies of the station in ascending order. No other lists have to be filled. Example: 88.1 91.3 104.1 104.5 20 ...
Page 21
RDS Encoder User Manual Rev 2.2 METHOD “B”: This method is used where the number of alternative frequencies used by a transmitter and its associated repeater stations exceed 25, or where it is required to indicate frequencies which belong to different regions which at times carry different programs. Each transmitter and associated repeater stations broadcast the same set of different AF lists in sequence. The number of AF lists within a network is in general identical to the number of transmitters and repeater stations in the network so as to provide a unique list for each transmitting station. In this protocol the alternative frequencies for the VHF/FM transmitters are individually addressed by transmitting the tuning frequency paired with one alternative frequency within one block. Each list starts with the tuning frequency for which the list is valid. All remaining pairs (up to 12) give the tuning frequency together with a valid AF. Usually, the tuning/AF pair has to be entered in ascending order if the AF is not a regional variant of the tuning frequency, on the contrary the order has to be reversed. If the number of AFs of a station is larger than 12, the list must be split into two or more lists. These lists are transmitted directly one after the other, and the receiver must combine the lists again. If a transmitter frequency is used more than once within a network the respective AF lists are transmitted separately. In order to indicate that these lists with the same tuning frequency belong to different stations, the lists must be separated by AF lists of other stations. 21 ...

RDS Encoder User Manual Rev 2.2 To simplify the programming of a B list, put into the first line AF1 the main tuning frequency, then enter on the other lines (AF2 to AF13) a maximum of 12 alternative frequencies, then press the button "Build B list." If you, in future, wish to add some new frequencies to the list, simply enter them at the bottom and press the button "Build B list." In the above example, all alternative frequencies of the main tuning frequency 90MHz are entered. Pressing the “Build B list” button, you get the list compiled using method “B”. Note: the list is compiled assuming all AFs are not regional variants of the tuning frequency. If there are one or more regional variants in the list, once compiled, they have to be edited manually. 22 ...
