Page 8: Overview Of The Rds Service
The buf fered outputs of STARGATE can drive cable lengths of upto 100 m before any appreciable distortion occurs to the MPX signal. - Page 9 AEV STARGATE Figure 1 The signal is transmitted by amplitude modulating, in suppressed carrier mode, a 57 KHz (3 times the 19 KHz pilot) subcarrier with a deviation of ± 2 KHz of the RF carrier, retaining a maximum deviation of ± 75 KHz for the multiplex, composite audio/data signal.
- Page 10 AEV STARGATE Figure 3 The system satisfies the protection ratios specified by the CCIR for mono and stereophonic transmissions. Figure 4 Protection ratios for FM radiophony (max. deviation: ± 75 KHz) Fig.5 shows the protection ratio curves for the three services.

Page 15: Rs232 Serial Port
AEV STARGATE In the event of monophonic transmissions, the RDS data encoder should be connected between the last low frequency unit in the audio chain and the transmitter. RS232 Serial Port The Serial connection RS232C is standard and has a 9 poles Cannon connector. - Page 16 AEV STARGATE Select the RS232 icon and the following window will appear: Let’s now see the parameters and their meaning: - RSD Option this is used to choose whether a coder programmed locally or via satellite is involved. This choice affects all the programming windows and disables or enables certain functions.
- Page 17 AEV STARGATE - Stop Bit This parameter may not be altered. It is used to display the status of the "Stop Bit". For connections in downlink from satellite mode, a baud rate of 9600 must be set unless requested otherwise in the technical specifications of the satellite downlink..
- Page 18 AEV STARGATE pressing the push button with a PC, a menu of boards will appear. By clicking on the tab of the board, the option to be modified can be selected. The first board illustrated will be that of the Program Service Name.
- Page 19 AEV STARGATE Following the same programming procedure as that for the PSN, enter the transmission Time (sec) of the string of characters then, in the Radio Text box, enter the text of up to 64 characters. Up to 50 strings can be entered.
- Page 20 AEV STARGATE Select the programming mode amongst those offered. Now, going on to a new setting, the 4-figure PIN code will automatically be created. The last box shows whether the setting has already been made (Yes) or whether it is still to be processed (No).
- Page 21 AEV STARGATE Method B enables the entry of frequencies with steps of 50 KHz. Up to 50 groups of alternative frequencies can be entered. Each group can bear up to 12 alternative frequencies, plus the main frequency. To make the setting, select the list desired. A comment concerning this group can be entered in the Descr ipt ion field.
- Page 22 AEV STARGATE specification of that type in the right box. 8 characters at the most can be used. For example PTY sport, Name football. Let’s now analyse the menu used to set the Program Service Name. Up to 200 settings can be programmed using this menu.
- Page 23 AEV STARGATE Let’s go back to the main board, press push button CT-PI - ECC - LIC - TP - DI, to gain access to the Clock Time board. . In a very simple manner, the date and time can be assigned.
- Page 24 AEV STARGATE In the following board, the parameters of the Program Identifier can be entered together with relative further extensions. The first setting to be made is the type of language used in transmission (Language identification Code), then select the country (Country Selection), then the type of coverage (Coverage area Selection) and finally the ID.
- Page 25 AEV STARGATE the information set previously. Let’s now see the “live” controls window. .Press any one of the red push buttons to immediately transmit the functions in use to the coder, with the exception of Program Type. To do this, make the selection using the combo box and then press the relative push button.
- Page 26 AEV STARGATE the radio in the PSN box, in our case radio SUN, enter the two frequencies in the boxes at the side of AF Method A writing, in our case 100.0 and 104.5 in the second box. Finally enter code 5159 in the PI box.
- Page 27 AEV STARGATE The last functions available relate to the Transparent Data Channel, to the In House Applications and to the Traffic Message Channel. These functions have been designed in compliance with the Cenelec EN50067 standards and can be used only with special decoders.
- Page 28 AEV STARGATE The pages available are pointed out by the lighting up of the relative traffic light. To modify a page, retrieve it using the combo box. From the editing window, make the desired modifications and then save the page using the Write Page push button or send it using the Send push buttons.
- Page 29 AEV STARGATE The LTN code is found in this board, Location Table Number, together with the SID Service Identifier, plus the setting of the coverage area, which can be considered as an identification code of the sender, similar to the PI.
