DMR repeater 25/01/2011 Versione 1.3 Pag. 3 / 8 1 TUNE UP INFORMATION Tune up process of RA-xxx equipments is very simple and can be made through a PC with installed DMR_manager application. Every setting of the transceiver can be changed by SW application only. 1 1 . . 1 1 Q Q U U I I C C K K I I N N S S T T A A L L L L A A T T I I O O N N A A N N D D P P O O W W E E R R O O N N The base station is equipped with a discrete set of HW connectors on the rear side, but only few of them are essential for working; the following connections are needed: ∞ Power supply: by 12V battery with negative to ground; nominal power supply voltage is 13,8Vdc, minimum is 10.8V and maximum is 15.4V, with electronic protection from overvoltage and undervoltage. Current absorption is 1A@1W, 5A@25W, max 7A. ∞ Main RX / TX antenna; for laboratory test, it is better to connect a 20dB RF attenuator between radio equipment and the antenna; ∞ Ethernet: TCP/IP connection to the same LAN as for the PC for remote control. The following picture shows the basic connections in red colour and optional ones in blu. When the equipment is powered on, it automatically performs the following actions: DMR repeater 25/01/2011 Versione 1.3 Pag. 4 / 8 ∞ Linux booting, during which LEDs of DSP module are yellow; ∞ download of software applications to DSP, clock generator and eventually to microcontrollers of peripheral modules which LEDs are flashing yellow and green; ∞ self calibration test, with the aim to tune the parameters of modulator and of demodulator and to test the overall performances. It taks about 1 minute, during which LEDs are flashing green and red. At the end of this process, only the following LEDs will remain on (see User Manual for further information): ∞ on PSM module, both leds will be green, monitoring the correct supply; ∞ on DSP module “LINK” led is green if equipment is connected to ethernet LAN, “ACT” led is flashing yellow if LAN communication is present; Now the equipment is ready to be tuned through a PC connected to the same LAN. The Ethernet interface of RA-xxx transceiver is auto-sensing: both straight and crossed cables are allowed. On a PC the application “DMR_Manager.exe” shall be installed (see User Manual for further information) and launched. The equipment can be accessed at a specific IP address, as indicated on a side of the equipment itself. 1 1 . . 2 2 T T U U N N E E U U P P P P A A R R A A M M E E T T E E R R S S RA-xxx equipments can work in dual mode, that is, they can recognize if the incoming signal from a terminal equipment is analog or digital and configure itself as analog or DMR. The remote control SW is very powerful and complex, but few mask are enough to set and to monitor the basic analog and DMR parameters.

Radio control. This mask allows the following actions: ∞ to change power of RF transmitter from 1W to 25W; ∞ to change frequency of RX and TX, or to change the current channel; ∞ to change TCS/DPL ; ∞ to check the main analog measures which are automatically performed. Eventual modifications of parameters will not be saved into internal flash: in order to permanently change parameters, channel table must be edited (by the mask RA-DMR
Radio Configuration
Channel table). If frequencies are significantly changed (some MHz), it is suggested to make the transceiver perform a new self-calibration process. In order to do this, the last channel (the 201 st ) of the channel table contains self-calibration frequencies parameters: you should change the frequencies of both working and self-calibration channel. Specifically in detail, the TX and RX frequency of calibration channel must be the same, they must be multiple of 100KHz and must be as nearest as possible to the TX frequency of working channel. In order to make the modification active and to perform a new self-calibration, the application on the equipment can be restarted by the command RA-DMR

DMR repeater 25/01/2011 Versione 1.3 Pag. 7 / 8 The transmission can be enabled by different commands to get different effects: ∞ if the “repeater mode is enabled” the equipment will transmit the same received signal.
