DMR_Manager Operating Manual 2011/07/04 Version 1v2Reserved Document – Don’t forward without authorizationPage 4 of 511 INTRODUCTIONThis document illustrates the applications and how to use the Radio Activity DMR base stations managementsoftware.Radio Activity DMR base stations can support a lot of applications and the management software is designedwith forms for reading the parameters that can change depending on the particular application.For that reason the forms shown in this document may be different from the ones in use or they could notappear in your application if the specific functionality is not enabled.Some forms may be incomplete because it is a work in progress, please notify us errors or inconsistencies.
DMR_Manager Operating Manual 2011/07/04 Version 1v2Reserved Document – Don’t forward without authorizationPage 5 of 512 CONCEPTS OVERVIEWThe Radio Activity DMR Base Station can include several TRX (master and slaves), where TRX refers to atransmitter, one or many receivers, DSP, IO board and a power supply.Radio Activity DMR Base Stations allow many different applications: they can work like a single repeater or in aradio network made of different repeaters linked together in different way such as Ethernet link, RF link.22..11TTRRXXAARRCCHHIITTEECCTTUURREEThe core of “physical layer” of the system is a unit which via software performs every function of signalprocessing into radio station.So, it is not necessary to add boards (like synchronizers, phase and amplitude equalizers, signal decoders,modem, etc.) because the functions can be implemented by routines which can be freely matched, down-loaded and with superior performance.Communication and control functions of module are entrusted to a microprocessor which managescommunications with external world and with other equipment modules. The microprocessor is based onLINUX operative system; it can manage a LAN ethernet 10/100 interface both for copper line and for opticalfiber links, it is equipped with 4 serial ports to manage radio modules, GPS, auxiliary devices, external hosts; itis equipped with a Real Time Clock with tampon battery; it controls an embedded PLL to synchronize theentire station upon an internal (VCTCXO 0.5 ppm) or external temporal reference. DSP module is equippedwith a synchronous serial port according RS485 standard levels, which can be programmed up to 16Mbit/s andcan be used to interconnect together more transceiver or additional equipments.Main performed functions are the following:∞Frequency self-tuning device∞Deviation self-calibration device∞Analogical and digital demodulation∞RF circuits testing∞Phase modulator calibration∞RF output power control∞Low frequency lines management∞DMR protocols management∞Digital signals processing∞Management, conditioning and routing of traffic and remote control signals from and towardsexternal worldReceiver can be supplied as single or double for space diversity reception. Main and diversity channels arecompletely independent and coherent (sharing the same local oscillators) and they are designed according toan heterodyne structure, with vectorial conversion to base-band.Channel standard bandwidth is 12.5 KHz, but the receiver is prepared to accept also a settable channelbandwidth of 25 KHz, 20 KHz, 10 KHz (with double funnel option) for special applications.Receiver module is managed by a microcontroller unit whose program is hosted inside internal e2prom flashmemory to lower parasitic emissions. This FW can be loaded through serial connection. The microcontroller, inaddition to managing internal function of the unit, transfers measured parameters to the control unit through115.2 Kb/s serial line.
DMR_Manager Operating Manual 2011/07/04 Version 1v2Reserved Document – Don’t forward without authorizationPage 6 of 51The board is realized with surface mounting components (SMD) to maximally reduce dimensions.On the frontal panel 2 LEDs are placed for monitoring internal PLLs lock status.Transmitter module is realized with surface mounting components (SMD) and it is housed in a shielded, 8TEbox for 220mm Eurocards, with an heatsink mounted on side, with a thermal resistance of about 1.2°K/W. Theunit can be extracted from the front side of the rack. On the frontal panel two LEDs are placed to monitor thetransmitter status.Base-band functions, equalizing, limiting, low-pass filtering end eventual emphasis functions are performed bythe DSP unit, which provides also for nominal and maximum deviation calibration by looping modulator withreceiver.Modulator is digital vector, then the synthesized signal by local oscillator implements the frequency shifting ofthe signal which has been directly modulated in base-band by DSP unit and transferred to transmitter throughits I and Q components.The amplifier is realized by three cascaded stages and RF output power regulation (between 1 and 25W) isimplemented by controlling the stages. Power amplifier works in C class and ensures a very high efficiency,lowering the needed power from supply system and lowering the thermal dissipation inside the cabinet. Directand reflected output power are measured by a directional coupler. Power control circuit acts in a closed loopand keeps constant the total power at MOSFET drain. Inside the module a thermal sensor is hosted and it isdirectly connected to the internal microcontroller which enables the command for air forced cooling fan of thecabinet if the temperature rises over 85°C. Anyway, if reflected power or mosfet temperature exceedsprotection threshold, regulation circuit will lower output power up to safe levels for transmitter.The current flowing into final amplifier transistor is continuously monitored by microcontroller to verify thecorrect functioning and to reveal any efficiency degradation.The module is equipped with an harmonic filter to lower spurious emissions under required levels by existingregulations.22..22RRAADDIIOOAACCTTIIVVIITTYYDDMMRRRREEPPEEAATTEERRAANNDDUUPPGGRRAADDEEAABBIILLIITTYYTTOOSSIIMMUULLCCAASSTTNNEETTWWOORRKKRadio Activity DMR repeater is designed to be modular from both HW and SW point of view, to maximize itsflexibility and minimize costs, physical dimensions, consumptions.Basic model already has all the characteristics to work as a double standard repeater with all the features ofanalogical and digital service. It can be equipped with double receiver to counteract fading effects throughdiversity space reception. It is set to host communication and synchronization embedded devices to make thenetwork expandable to a multi-frequency or single-frequency multi-site system, with different types of links,operating with different transportation system topology, like microwave, UHF, optical fibers, IP connections.Privileged communication interface is Ethernet standard type, compatible with more diffused technology. Thisinterface supports not only voice and data digital traffic, but also remote control management, which forRadio Activity equipment is very powerful: it is possible to have a complete monitor system of equipmentstatus, it is possible to modify each parameter, to down-load each SW and configuration, launch self-test andcalibration functions, to perform specific tests through internal embedded function generators and softwareanalyzers of the station. For analogical voice traffic instead, a 2/4 wire and criteria line interface is available.
DMR_Manager Operating Manual 2011/07/04 Version 1v2Reserved Document – Don’t forward without authorizationPage 7 of 51Remote control service can be performed through an Ethernet connection pre-existing in the site, or throughGPRS modem which can be integrated into the station, or through the radio channel and another RadioActivity station.Fully modular structure allows to best configure the radio equipment, by adding and/or changing the requiredHW and SW functional blocks, to work as simple repeater, multi-frequency multi-site repeater, single-frequency multi-site repeater.22..33NNEETTWWOORRKKIt is possible to configure the network in many different ways, with different kinds of links (Ethernet, RF,Optical fibers)2.3.1 MASTER BASE STATION IN “RF LINKED” NETWORKSThe master base station is equipped with a “voting system”, which select the “best” signal among all thesignals received by the Satellites and the local receiver(s).Besides this the master sends the digital synchronization towards the satellites and, in the case of BaseStations “RF linked” equalizes the absolute and group delay due to the RF channel.2.3.2 SATELLITE BASE STATION IN “RF LINKED” NETWORKSThe duty of the Satellite is:∞receiving the signals from the terminals and sending them to the Master through the RF link,∞transmitting to the terminals the signals received by the Master (voted) through the RF link.The satellite performs also the group delay and absolute delay equalization on broadcasting transceivers bothdown link and up link.22..44SSIIMMUULLCCAASSTTNNEETTWWOORRKKSSSimulcast type networks operate on the same radio channel on the whole coverage area.Communications can be both open and selective channel, semiduplex mode between mobile terminals orduplex mode between Central and terminals. The network will make the automatic selection of accessingterminals and will broadcast the signal on the same frequency throughout the coverage area. The terminalsare served regardless of their position as if they were covered by a single repeater.All transmitters send the same information signalson the same carrier frequencyfcfcfc

The signal voted is sent to the satellite andthen diffused in the whole coverage area.Simulcast networks require also particular attention in the choice of media linking the various stations. Thecharacteristics of these media must be such as to make as much as possible identical signs of low frequency(audio) that each station must retransmit.For that reason simulcast networks made byRRaaddiiooAAccttiivviittyyemploy equalization devices based on DigitalSignal Processing, which are able to automatically minimize the differences between the media pathsThis feature allows to use a large family of communication media, including time-varying lines as pupinizedcopper, presenting considerable variations in temperature, or as non-dedicated telephone lines and thereforesubjected to variations of delay and BF response..TRXVHFTRXVHFTRXVHFRF broad.Km_2RF broad.Km_1RF broad.Km_0MUX_1delayMUX_2delaySLAVE2SLAVE1MASTERLinear simulcast network configuration

This means that through the same radio channel broadcast by radio network,two digital communications can be established, and the radio channel capacity is doubled. The use of twotimeslots allows also to exchange control signalling while radio communication is in progress, in order tomanage, for example, the communication priority or to remote control the terminals functionality .CH1CH2CH1CH2CH1CH2CH1CH2Group 1 Group 2TimeCH2FrequencyCH17.5KHzCH4CH37.5KHz12.5KHzTwo contemporaryand indipendentcommunications onthe same frequencycarrier30msA physical radio channel is identified by a couple of frequencies (Duplex and Semiduplex).Digital modulation requested by DMR standard (4FSK) allows an increased data transmission capacitycompared with analogical traditional systems. In fact the system supports data transmission speed up to 9.6Kb/s over the 12.5 KHz wide radio channel. It is possible then to implement data services with added valuebetween terminals and the operative central, like for example radio traffic management and messages,localization through GPS (Global Positioning System) management, telemetry, with performances greatlybetter then what analogical systems can offer

DMR_Manager Operating Manual 2011/07/04 Version 1v2Reserved Document – Don’t forward without authorizationPage 39 of 51Menu itemDescriptionSynchronism sourceAllows to choose the synchronism sourceNo syncNo Synchronism source selectedDigitalSynchronism based on a proprietary pattern sent at the beginning of thetransmission and then on superaudio tones.InternalThe synchronism source is a crystal oscillator placed inside the DSP module, whichhas a stability better than 0.5 ppm in the thermal range of functioning. On demand,higher stability oscillators can be used. The frequency tuning is digitally controlledand the setting can be stored. An internal self calibration function allows to correctthe natural aging of the oscillator, by simply connecting the receiver to a calibratedexternal source.From multichannelThe synchronism is obtained from Audio LAN connection clock (patch cord on therear of the rack). This synchronism can be required for systems with more digitallylinked together radio stations.Equipment synchronization time <2 sLong period relative stability 0 ppmShort period relative stability <0,001 ppmFrom PPS GPSThe GPS receiver (inside the station) provides a pulse every second, which is used bythe DSP to clear its frequency and time reference. The time reference allowsautomatic equalization of absolute delays of the links (useful in networks with IPlinks or MUX SDH links with automatic reconfiguration of routes in case of backbonefailure). In the case of GPS failure the synchronism is automatically switched tosuper-audio tone received from the master station (see following method).Equipment synchronization time <120 sLong period relative stability 0 ppmShort period relative stability <0,01 ppmFrom superaudioA super-audio tone, superimposed to the analog signal, is the reference for the DSPto lock its internal clock. That tone, whose frequency can be freely set between 3100and 3400 Hz (typ = 3400Hz), is sent 10dB lower than the nominal audio level.Equipment synchronization time <60 msLong period relative stability 0 ppmShort period relative stability <0,01 ppmFrom 4 FSK timeslotSynchronism based on the 4FSK timeslotTo enable these functions click on Set ; All the parameters will assume their original values if you restart thedevice, unless you perform a Save in eep operation (see the DMR LAYER CONFIGURATION paragraph).6.2.2.9 SUBTONE / SUPERTONEClicking on RA-DMR RadioConfiguration Subaudio/superaudio the subaudio/superaudioform will appear:
