12V C Power Supply Power supply connector. See section 3.3 for details.
Ethernet Ethernet RJ-45 connector.
Use a standard (direct) cat 5 Ethernet cable for connection to the Ethernet switch, router or wall-socket.
The Ethernet control includes internal website (referenced as “Port 2”) and two independent user
configurable general purpose ports (referenced as “Port 3” and “Port 4”) designated for remote control via
TCP or U P protocol.
The encoder operates also with no cable connected.
RS-232 RS-232 standard male type connector. This port is referenced as “Port 1”.
If you cannot reach the R S encoder over the LAN, use the RS-232 for initial setup of the encoder or for its
local control. For wiring, see the section 3.4.
The port is internally optically isolated from the rest of the encoder’s circuitry to prevent ground
loops and to keep high E D immunity and EMC.
The encoder operates also with no cable connected.
Output BNC R S signal output, modulated at 57 kHz subcarrier.
If the Loop/Side switch is set to the LOOP position, the Output is a sum of the R S signal and the signal fed
to the Input BNC connector.
Input BNC Optional input for synchronization to the pilot tone or for mixing the R S signal with existing modulation
signal.
Loop/Side switch Allows the input signal to be added to the output signal. See sections 3.1 and 3.2 for details.
GPIO Optional logical inputs for direct control of some R S services (TA, PROGRAM).
See the Technical manual for details. The connector is a standard 6-pin PS/2 type.

Hardware Installation
3.1 Connecting the RDS Encoder
Basic rules applying for any R S encoder’s connection:
 The R S signal must be fed into modulation input (added to MPX signal if stereo encoder is used).
 If stereo encoder is used, one of its outputs (MPX or pilot tone) must be fed into the R S encoder input to meet the synchronization
requirement.
Following figures show various situations and corresponding methods of connection. Use shielded cables (e.g. RG58) terminated by BNC male
connectors. The cables should be kept short in length. Where necessary, use a BNC ‘T-piece’ for splitting the signal.

In case of mono transmission (no stereo encoder used) the R S encoder input may be left unconnected (since there is no need of external
synchronization) or it may be used for the audio signal injection in the case that the FM transmitter has only one input connector.
3.2 Hardware Settings
.2.1 On-board adjustable elements
ue to completely SP-based solution there’s no adjustable element on the board affecting the R S or MPX signal.
User is not allowed to open the encoder’s case.
.2.2 Loop/Side switch
Select the LOOP position only if it’s necessary to pass the input signal to the output of the R S encoder (loopthrough mode).
In all other cases the switch must be fixed in the IDE position!
Always make sure that the switch is securely fixed in the position desired and eliminate possibility of unwanted change of its state!

3.3 Power Suppl
The R S encoder can be supplied from any power supply, which delivers a stabilized 12 V voltage and a current of at least 500 mA.
Commonly available switching wall adapters are usually suitable for that purpose. The R S encoder includes polarity and short-circuit
protection. The central conductor of the power supply connector is positive (+).
Note: After first power-up, there is no need to configure anything to turn on the RDS subcarrier. The RDS encoder will i ediately start to
generate the RDS signal with factory default values (PS: * RDS *, PI: FFFF, RDS level: set to axi u 4000 V p-p).
3.4 Connecting the RDS Encoder to a Local PC or a DCE Device
For the purpose of initial configuration and local or special control requirements the R S encoder is equipped with standard RS-232 interface
provided on -SUB9 male connector on the rear panel of the R S encoder. This connector allows direct connection to a PC using a standard
serial laplink cable (null-modem, crossed) or USB cable with built-in RS-232 converter.
.4.1 Connection to a serial port of the PC
On the PC side locate an unused COM port. If the free port exists in the form of a 25-pin connector, use a standard -SUB9 (male) to -
SUB25 (female) adapter. Make sure the COM port is enabled in the PC’s BIOS Setup.

It’s preferable to use standard serial laplink cable terminated with 9-pin female connector on the PC side and 9-pin female connector on the

enough for the connection.

.4. Connection to a USB port of the PC
Connection to USB port of your PC is possible via standard USB to RS-232 cable. It is also known
as USB to RS-232 adapter. A serial laplink cable is also required to be present in the chain.
USB driver must be installed prior to start communicating. Virtual COM port feature provides
seamless compatibility with broadcast automation software.

3.5 RDS Level Adjustment
Important note: There is no universal setting for the RDS level. Due to different input sensitivity of different FM broadcast equip ent it's
necessary to check and adjust the RDS level!
The correct level should be between 2 and 11 % of the audio multiplex signal, measured by oscilloscope in peak-to-peak values on the
modulator input. Recommended value is such that results in 3.4 kHz deviation of the FM carrier. on’t forget that the maximum total FM carrier
deviation with R S and MPX signal is 75 kHz. It is much easier to use an FM broadcast analyzer for setting the R S level precisely.
The R S level can be adjusted after establishing a connection to the encoder, using one of these two methods:
In the Windows software
Go to Options – Preferences – Control and check the item ‘Enable R S level control’. Now the control is available on the System sheet in the
main window.
The software allows adjusting the R S level in range 0.4 to 100 %. In the P332 R S encoder, that range is proportional to the output level
range of 15.6 to 4000 mV p-p. Confirm the setting by Store button.
In the embedded website
Click on menu item Setup – Signal Control and enter the R S level directly in mV p-p unit.
In terminal, using A CII command LEVEL=
The P332 R S encoder allows direct adjusting of the R S level in 256 steps, in range 0 to 255, by assigning a corresponding value to the
LEVEL parameter. Each step represents approx. 15.6 mV increase.

4 Software Installation
4.1 Establishing a First Communication with the RDS Encoder
The R S encoder should be configured via local port (port 1) before first use. Alternatively, the configuration can be made using the embedded
website.
The encoder comes initialized from the factory. The Ethernet is pre-configured in order to obtain IP address from HCP. Thus, in the HCP
enabled environment, the first connection with the encoder can be established using a web-browser and typing the assigned IP address into
the address field. See more details in section 3.1 of the document ‘P132 R S Encoder – Communication Ports and Internet Functions’.
For local configuration via port 1, please follow these steps:
1. Install the Windows control software called ‘Magic R S’, run the setup exe file and go through the simple installation wizard.
2. In the case of using USB adapter, install the USB driver now.
3. Make sure the R S encoder is connected and powered, and all connectors are seated completely.
4. Run the Magic R S software using Windows Start button.
5. Open the Preferences (Options - Preferences) and set up the connection parameters. Choose the Serial RS232/USB connection type
and select the COM port the R S encoder is connected to. If the R S encoder is connected via USB and was recognized correctly in
Windows, you may find/change the COM port number in Windows Control Panels - System - Hardware - evice Manager or simply click
on the List button.
6. Close the Preferences. You should see "Connected" or "Opened" in the status bar. Now you are ready. The settings are saved
automatically.
7. The status bar at the bottom of the window shows whether the data was sent successfully. If Communication Error! is shown, check the
connection to the R S encoder, its power supply and that the correct COM port is selected in the Preferences dialogue box.
8. Follow the instructions from the application Help.
Note: The RDS encoder contains two types of e ory. These are arked as RAM and EEPROM. Like any other co puting syste the RAM
holds all operational data which are also used for trans ission whilst the EEPROM is used for the data storage during power-off. By default the
button Send will fill the RAM only. The button Store will fill the RAM and also stores the data into EEPROM. The Store button behavior can be
changed in Options - Preferences - Controls.
If the user forgets to store the data into EEPROM, the settings will be lost when the power is disconnected.
