INTRODUCTION The RF Unit is the RF transceiver of Teltronic P25 systems, with a transmitter output power of 100W. Therefore, this is a mandatory module in the infrastructure P25 network. It is manufactured following a robust mechanical modular design which allows simple and economic maintenance. The RF Unit is available in the following frequency bands:  380 - 400 MHz  410 - 430 MHz  450 - 470 MHz  764 - 806 MHz  806 - 870 MHz The modules that form the RF Unit are:  RPS (Repeater Power Supply P25)  RPA P25 (Repeater Power Amplifier P25)  RTX P25 (Repeater Transmitter P25)  RRX P25(Repeater Receiver P25)  BSYNC (RF Unit Synchronism) - OPTIONAL  RCPU P25(Repeater Control Processing Unit P25) The proper operation of any electronic device depends on its correct use. It is therefore recommended to follow the instructions in this manual. !CAUTION: Switch the RF Unit off before inserting/removing any of its modules.
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 5 of 16 01.01.00/1 Rev.1 2. UNPACKING AND CHECKING The following elements are supplied in the box: RF Unit 50Ω / 20W load termination Power Supply Cable Maintenance Cable Two Ethernet Cables The equipment is supplied with all the modules already assembled in the rack. The modules in the basic configuration are: Power Supply module (RPS), Power Amplifier (RPA P25), Transmitter (RTX P25), Receiver (RRX P25) and Control (RCPU P25). Synchronism module (BSYNC) is necessary for testing purposes. IMPORTANT: if any of these elements is missing or damaged, contact your dealer and / or installer. 3. PREVIOUS CONSIDERATIONS This manual contains information on instructions for installation, maintenance and use. Read the following pages before using this equipment. Do not switch on the RF Unit without having previously connected the TX antenna and the 50Ω load to the TNC connector. The equipment may be seriously damaged. It is important to use an antenna adjusted to the RF Unit transmitter frequency band. INFORMATION ON SAFETY AND ELECTROMAGNETIC COMPATIBILITY The equipment has been designed to fulfil the applicable compliance regulations. The equipment complies with Part 15 of the FCC Title 47 of the Code of Federal Regulations. Operation is subject to the condition that this device does not cause harmful interference. The equipment complies with the applicable Part 90 of the FCC Title 47 of the Code of Federal Regulations.
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 6 of 16 01.01.00/1 Rev.1 In any case, take the following points into consideration:  Most electronic equipments are susceptible to electromagnetic interference if they are not duly protected. If the RF Unit is placed near unprotected electronic devices, they may malfunction.  The RF Unit must not transmit without its antenna connected or without the 50Ω load in the TNC connector.  When installing the antenna, follow the guidelines for exposure of the human body to high and low frequency electromagnetic fields. Follow the supplier’s / manufacturer’s instructions.  Burns may be suffered if the antenna connector output of the power module (RPA P25) is touched by bare skin when the RF Unit is transmitting with the antenna disconnected.  Take care when handling the RF Unit. It has sharp edges, which may cut if handled incorrectly.  Maintenance and repair of these repeaters must be carried out by qualified personnel only.  Connect the RF Unit chassis to the earth intake in the cabinet where it is to be installed.  Switch off the RF Unit before inserting/removing any of its modules !

RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 12 of 16 01.01.00/1 Rev.1 6. INSTALLATION GUIDE The following recommendations must be followed closely before starting up the RF Unit module. 6.1. LOCATION The RF Unit has been designed in the standard format of 19” / 3 units high and it must be installed in cabinets with this format. The RF Unit site must be permanent, well-ventilated and without vibrations. 6.2. POWER SUPPLY CONNECTION DC power supply: check that the power supply source and/or the battery to be used meets the voltage and current requirements necessary to supply the equipment:  Nominal voltage: 26.4VDC (range: from 21.12 to 31.68 VDC).  Minimum source current: 20 A.  There is a 15 A internal fuse in the RPS module (Ref. 1 of RF Unit) to protect the equipment from over-voltage. There is a power control circuit in the RPS P25 module in order to avoid an over-current condition.  If lead batteries are used, they are to be placed as far from the RF Unit as possible to prevent corrosion in the repeater due to battery vapours. They should be situated in a well-ventilated place.  Use the power supply connector provided (D013000) to connect the RF Unit to the power supply source. Use a cable with 2.5 mm2 minimum diameter (or AWG-12). Ensure that the connection is made with the correct polarity.  Ensure that the earth connection is made. Make this connection with a cable of maximum diameter and minimum length. NEVER use a gas or electricity conduit as an earth.
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 13 of 16 01.01.00/1 Rev.1 6.3. ANTENNA CONNECTION  Choose the most adaptable antenna for the installation. The antenna must have an impedance of 50 ohms to the equipment transmission frequency. Install the antenna in accordance with the manufacturer’s instructions.  Use a coaxial cable, avoiding as much as possible large cable lengths. Cable impedance is 50 ohms.  Measure the ROE of the installation. Never accept a ROE greater than 2.  If a duplexer module or a band pass filter is required, adjust them to the working frequency before starting up. 6.4. SWITCHING ON THE RF Unit  Check the connections between the modules.  Check that the power supply source is connected correctly.  Check that the RF SMB cables are connected correctly (see Rear View diagram Ref. 10).  Check the connections of the antennas in the RPA P25 and RRX P25 modules.  Check the 50Ω load is connected to the rear TNC connector in the RPA P25.  Check that the RPS P25 module LED SUPPLY is on.  Activate the power on switch on the RPS P25 module.  Check that the 26.4V LED and 13.2V LED on the RPS P25 module are on and check that the LEDS “ON” are switched on in the other modules.  Wait for the RF Unit to start up. Note: See subclause 5.3 for more information on references for the different modules and LEDs.
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 14 of 16 01.01.00/1 Rev.1 7. CONFIGURATION A RF Unit is configured via an NMS (Network Management System). To configure the RF Unit, consult the NMS manual. 8. INCIDENTS The repeater must be repaired by authorized technical personnel only. If a RF Unit failure occurs, the entire RF Unit must be replaced. If transmitter module is damaged and there is not an entire RF Unit available to replace, set RTX P25 and RPA P25 modules previously calibrated jointly. In last case and if is not possible to carry out one of the two previous options, replace one of these two modules and make the gain calibration again. If an error or alarm occurs in the RF Unit, this is indicated in the corresponding LED for each one of the modules. The following list shows the possible failures and their solutions. 8.1. ALARMS Led indication Status Failure / Solution RPS SUPPLY OFF POWER SUPPLY FAILURE. CHECK THAT THE SOURCE AND THE POWER SUPPLY CABLE ARE CORRECTLY CONNECTED. CHECK THE INTERNAL FUSE OF THE RPS.
