INSTALLATION The installation of any electrical equipment should be made by trained technicians who know the risks related to handling electrical supplies. Before proceeding with the installation, it is necessary to verify that the equipment is in compliance with the rules of the Country where the unit will operate. Before connecting the transmitter to the AC source, it is necessary to verify that the voltage range reported in the back of the unit matches the voltage of the AC supplied.
KWatt isolation transformer). If you want to protect more devices you should add the wattage of every unit and multiply by 2.5. Once you have your transformer installed, you need to verify how good your ground system is. Every good electrician should have a proper device to measure the ground. Money invested in measuring your ground can fix problems and avoid bigger expenses in the future. Every rack and every unit must be connected to ground.
CONNECTION AND OPERATION 1. First, connect the transmitting cable coming from the antenna to the corresponding connector placed in the rear panel of the unit; check that it is tightened properly. 2. Then connect the plug to the AC mains and also make a good ground connection. 3. Once these procedures have been performed, you can turn the power on. The transmitter requires about 20 to 30 seconds to perform the internal checks and lock onto the frequency. After that, it will start delivering power. 4.
SAFETY SUGGESTIONS Thank you for your business. We at Nicom appreciate our partnership with you and your broadcasting team. We proudly stand behind our products. Regardless of how well our electrical equipment is designed; personnel can be exposed to dangerous electrical shock when protective covers are removed for maintenance or other activities.
GENERAL INFORMATION FOR SAFETY When connecting recommendations: the equipment to power, please follow these important • This product is intended to operate from a power source that will not apply more than 10% of the voltage specified on the rear panel between the supply conductors or between either supply conductor and ground. A protective- ground connection by way of the grounding conductor in the power cord is essential for safe operation.
• When inserting or removing printed circuit boards (PCBs), cable connectors, or fuses, always turn off power to the affected portion of the equipment. After power is removed, allow sufficient time for the power supplies to bleed down before reinserting PCBs. • When troubleshooting, remember that FETs and other metal-oxide semiconductor (MOS) devices may appear defective because of leakage between traces or component leads on the printed circuit board.
• Before any maintenance work is carried out on automatic or remote-controlled equipment, the remote switching circuits shall be made inoperative. PROCEDURE FOR DETERMINATION OF THE ABSENCE OF VOLTAGE After the equipment has been isolated according to the standard EN60215, the absence of voltage shall be determined at the work place. This may be done by the use of voltage indicators, measuring instruments, glow discharge lamps for indicating radio-frequency voltage or other suitable means.
ELECTROSTATIC PRECAUTIONS Before removing or replacing any PCB assembly within the equipment, make sure that all precautions comply with ESD protections (ESD = Electro Static Discharge). Make sure that electrostatic discharge protections are reset after maintenance and/or measurement operations. The tag of CAUTION is used for the majority of electronic devices that are subject to electrical shocks.
RULES OF FIRST AID Personnel engaged in the installation, use and maintenance of the equipment must be familiar with the theory and practice of first aid. FIRST AID IN CASE OF ELECTRIC SHOCK If someone seems unable to free themselves when they receive an electric shock, disconnect the power before trying to help. A muscle spasm or unconsciousness may render the victim unable to free themselves from the power source.

The user Admin has the complete access to the WEB SERVER and its the only one able to set up new users, change settings and allow other users to do so. The user Amin is the only one with access to the tab ADMIN. In this Tab is where the ADMIN can define the User names, passwords and permissions. ADMIN: administrator who can change these settings; RD ONLY: Read-only, can access only the page HOME; WR & RD: Read and Write only, can make changes but no access to ADMIN.
The default WEB SERVER settings are: LOCAL IP: 192.168.1.100 Subnet Mask: 255.255.255.0 GATEWAY: 192.168.1.
The SMTP SERVER is still under implementation, soon it will be available. With this settings the transmitter is able to send EMAIL notifications about alarms and histoy of the tranmsitter. Under HISTORY there are all the alarms sent by the SMTP server In the lower part there is a TEST MAIL section which it can be used for testing the settings above.
In the SETTING tab is possible to change the Frequency, power level, Audio levels and the alarms. Under SETTINGS, there is the option to set a power reduction at a specific time of day.
Inside SETTING it is also possible to set the Audio Levels in every input of the transmitter. Again all changes needs to be confirmed with the SET button.
RDS Configuration Manual RDSM02 Windows control application for RDS encoders Table of Content 1 2 3 4 Installation.....................................................………………................................................ 2 Minimum Requirements.............................………………..............................................…. 2 Purpose and Features ............................................................................………………..... 2 Application Control.................................................
1 Installation 1. Download and run the installation exe file. 2. Select the setup language and finish the installation using the ‘Next’ button. 3. In the case of USB connection install the USB driver now. Pure RS-232 connection or parallel port connection requires no additional driver. 4. Make sure the RDS encoder is connected, powered and well configured, all connectors are seated completely and where possible, use screws to fix the connection. 5.
4 Application Control 4.1 Main Buttons Send Store Read Sends the data to the RDS encoder. That data will be used for the transmission until power off. Use this button also for confirm of RDS services settings, e.g. when changed Dynamic PS mode. Stores the data into the EEPROM memory so the data will be available also after next power-up or reset. Reads actual data from the RDS encoder. This button is allowed only in bidirectional communication mode. 4.
4.3 Dynamic PS Dynamic PS (DPS) is defined as using of the station name for showing of sequential information. Up to 72 characters long text message to be displayed on receiver instead of static PS name. Four display modes (0-3) are available. The user can insert the text manually from the keyboard or configure the ‘Text sources’ automation tool for Dynamic PS. The result can be immediately visible due to Preview feature.
4.4 Radiotext This refers to text transmissions, primarily addressed to consumer home receivers or mobile receivers, which would be equipped with suitable display facilities. The text can be up to 64 characters long. Some receivers do not support the Radiotext (RT) service. Enabled Radiotext messages Type Send next RT after Toggle RT type automatically Enables or disables the Radiotext, including all related functions. Note: If Radiotext is disabled, the encoder sends no 2A groups. A set of Radiotexts.
Cyclic User Defined Group Reset Read Status Switch Off Switch On The user may add one RDS group with any content to the RDS stream. This group is cyclically transmitted approx. twice per second. Insert the content in hexadecimal format. This feature is intended mainly for advanced users or experimental purposes. It may be used for example to include ECC code. Do not enable if you are not sure what you’re doing! Resets the RDS encoder. RDS data will be read from internal EEPROM.
4.7 Preferences Skin Picture and Font Color UTC Offset Summertime Offset Always on Top High Priority Confirm Exit PTY Coding You may insert your own BMP picture to the application, showed on the first page. You may also change the font color. To clear the skin, enter a non-existing file name. Your local time offset. Your summertime offset, usually 1. Keeps the application window on top so it is not overlapped by other windows. Assigns the application high priority.
5 Text Sources This tool can update Dynamic PS, Radiotext or both by actual text produced by your broadcast automation system or similar external application. The text processing scheme is as follows: Reading from file → Characters cutting → Processing Options → (Adding prefix) To get it working, set all parameters, then check the From file box. Dynamic PS and/or Radiotext must be Enabled. 5.
6 ANNEXES 6.1 Setting Basic RDS Data Before getting on-air with the RDS signal, you will need to decide on the settings to be used. The following RDS services should be set as the first. 6.1.1 PI (Program Identification) This is very important information that enables the receiver to distinguish between countries, areas in which the same program is transmitted, and the identification of the program itself.
Important note: Factory default PI value is FFFF and it's needed to change it as soon as possible to avoid the situation that two different stations with common area of coverage have the same PI. For each station in the same location the unique PI must be assigned. Stations that carry different program must be unambiguously identified by the last two PI digits. In other case they are recognized as one station by car radios, regardless of any other service settings.
6.2 Software Troubleshooting The RDS encoder uses simple connection and has been designed to make its use as easy and painless as possible. However, success depends upon several settings and things working together correctly. While correcting problems is usually quite simple, the difficulty lays in knowing where to look. This section is designed to assist you in determining the cause of problems that may occur when establishing a communication with the PC software, so they can be fixed quickly. 6.2.
Note: RF EXPOSURE SAFETY DISTANCE (only for FCC & IC) RF Exposure Limits for United States of America, according to FCC regulation: setting to the maximum of the output power of the apparatus, to guarantee the limits of exposure declared within this document, it is necessary that the antenna gain used with this device should be 0dBi or less and all persons should maintain a minimum separation distance of 266.13cm for general uncontrolled exposure and general controlled exposure.
