RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 4 of 16 1. 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.
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 5 of 16 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).
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 6 of 16 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.

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.
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 13 of 16 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.
RF Unit USER AND INSTALLATION MANUAL Code: D168X01_DDS09 Date: 09/10/08 Page: 14 of 16 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.
