Can therefore interoperate with any similarly compliant radios.■Linear power amplifier allows operation with Linear Simulcast Modulation (LSM). Future software upgrades will also allow P25 Phase 2 operation (H-DQPSK modulation).■Integrated built-in voting facility. No external voter is needed.■Can be completely managed remotely from a PC running a web browser: configuration, alarm monitoring, fault diagnosis, feature and firmware upgrades. Alarms can also be reported via SNMP traps, allowing integration with an SNMP-based network management system.■An integrated wiring solution is provided for the system control bus and DC power connections to each module in the subrack.■Reciters (receiver/exciter modules) can be replaced without affecting the operation of other reciters in the same subrack.■Rugged construction with generous heatsinks and fan-forced cooling for continuous operation from –30°C to +60°C (–22°F to +140°F).
TB9400 Installation and Operation Manual Description 11© Tait Limited November 20131.2 ModulesThe base station consists of a subrack with up to two transmit/receive channels, or up to four receive-only channels. Receive-only base stations are currently available for operation only on B3 band (148MHz to 174MHz1).The single PMU (power management unit) supplies and manages power to the whole subrack (refer to “Theory of Operation” on page 19). One reciter and one PA (power amplifier) are needed for each transmit/receive channel. The PA is not required for a receive-only base station. There is also a front panel with user controls and fans. The modules are interconnected at the front of the subrack. External connections to the modules are located at the rear.Modules come in different variants depending, for example, on the RF band or the supply voltage. Each module is inserted into the 4U subrack from the front and is secured at the front with a metal clamp. Both clamp and module are easily removed for rapid module replacement. The modules are secured laterally with plastic guides that clip into the top and bottom of the subrack. These guides can be easily repositioned to change the configuration of a subrack. The heavier modules are also secured laterally by metal tabs at the rear of the subrack.The following provides a brief description of the available modules.Reciter The reciter module comprises the receiver, exciter and digital control circuitry. The reciter provides the Ethernet interface and system inputs and outputs. Receive-only reciters are not fitted with the transmit circuitry or front panel SMA connectors, and are physically unable to transmit. 1. Refer to “Frequency Bands and Sub-bands” on page 17.
12 Description TB9400 Installation and Operation Manual© Tait Limited November 2013Power Amplifier The PA amplifies the RF output from the reciter and is available in 50W and 100W models.The 50W model mounts vertically in the subrack, while the 100W model mounts horizontally as it has a wider heatsink. The 100W PA is also fitted with an airflow duct.Both models are designed to operate on the 28VDC output provided by the PMU. PAs are not required in a receive-only base station.Power Management UnitThe PMU provides the 28VDC power supply for the modules in the subrack. It can operate on 120/230VAC 50/60Hz nominal, and 12, 24 or 48VDC nominal. The input voltage can be AC, DC, or both AC and DC, depending on the model. The PMU also has an auxiliary DC output of 13.65VDC, 27.3VDC, or 54.6VDC, depending on the model.50W PA 100W PAAC and DC PMU shown
TB9400 Installation and Operation Manual Description 13© Tait Limited November 2013Front Panel The front panel is mounted onto the subrack with two quick-release fasteners. It incorporates the indicator LEDs, four-line LCD display, user controls, ambient temperature sensor and cooling fans.The indicator LEDS allow some monitoring of the operational status of the base station. The user controls and display allow the technician to configure the IP address of each module. Refer to “Front Panel” on page 36 for more information.The microphone input and speaker are not used in this release of the TB9400.Subrack The 4U subrack is made of passivated steel and is designed to fit into a standard 19 inch rack or cabinet. The subrack is fitted with an interconnect board that connects the system control bus and power to the modules and front panel. The position of a module in the subrack is defined by the socket on the subrack interconnect board to which the module is connected by the system control bus.
14 Description TB9400 Installation and Operation Manual© Tait Limited November 20131.3 Mechanical AssemblyThis section illustrates the main mechanical components of the base station. Figure 1.1 below shows the configuration for a typical dual 50W base station. The subrack has six slots, numbered from right to left as viewed from the front of the subrack. The PMU occupies slots 5 and 6, with the reciter and PA pairs to the right of it in slots 1 to 4. Each PA is mounted vertically with its heatsink facing its associated reciter. The PMU and each reciter/PA pair have their own cooling fans.The front panel can be easily removed from the subrack by undoing two quick-release fasteners.

TB9400 Installation and Operation Manual Description 17© Tait Limited November 20131.4 Frequency Bands and Sub-bandsMuch of the circuitry in the base station is common to all frequency bands, and is therefore covered by a single description in this manual. In some cases the descriptions refer to specific bands or sub-bands, and these are identified with the letters listed in the following table.1.5 ApplicationsThe TB9400 is designed for operation in a Tait P25 trunked radio network. It can operate as a single base station or as part of a simulcast channel group, and as a traffic channel or control channel. In a trunked simulcast network, the transmitters in the channel group are synchronized and transmit simultaneously on the same frequency. Each transmitter needs a highly accurate 1PPS pulse and an external frequency reference, so that it can time transmissions with the required accuracy. We also recommend using an NTP server at each site, as this will ensure a common timestamp in logs across all units in the system.The base station can be provided as a receive-only variant in systems that need sites to enhance the receive coverage. The reciter in a receive-only base station is physically unable to transmit.For more information, refer to the appropriate Tait P25 System Manual.Frequency Identification Frequency Band and Sub-bandB band B3 = 148MHz to 174MHzH band H1 = 400MHz to 440MHzH2 = 440MHz to 480MHzK band K4 = 762MHz to 870MHzaa. The actual frequency coverage in this band is:Transmit: 762MHz to 776MHz, and 850MHz to 870MHzReceive: 792MHz to 824MHz
18 Description TB9400 Installation and Operation Manual© Tait Limited November 20131.6 LicensesSome operational functions of the base station are controlled by licenses. These functions will not work unless you purchase the appropriate feature license and enable the feature set controlled by that license. The feature sets currently available are listed below.P25 Common Air InterfaceAllows the base station to go into Online mode. Base stations are always provided with this license.P25 Trunking OperationAllows the base station to participate in a trunking system. Without this feature, the base station cannot provide a control or a status connection to a trunking site controller and it cannot function as a control or traffic channel.Networking with Centralized VoterThis feature is required in any base station that is used in a voted configuration, such as simulcast. It also allows a base station to act as a central voter.Simulcast TransmitterThis feature is required in base stations that have transmitters and belong to a simulcast network.Linear Simulcast ModulationAllows the base station to transmit using the LSM modulation scheme. This scheme allows increased site separation in simulcast networks.Failsoft for P25 TrunkingAllows trunked channels that become isolated from a site controller to perform simple conventional operation and to interface to a digital dispatch system. If a trunked channel consists of several base stations in a channel group, only the central voter (normally the master) needs this license. It is then able to become the failsoft repeater for that channel group. P25 Phase 2 Operation(not yet available)This feature will allow the base station to operate in trunking mode using two-slot TDMA as defined by the P25 Phase 2 standard.
TB9400 Installation and Operation Manual Description 19© Tait Limited November 20131.7 Theory of OperationThe reciter receives RF signals from its RF input and sends RF from its RF output to the PA, along with a PA key signal. The PA sends an RF feedback signal to the reciter for linearization and power control purposes. The reciter also receives signals from, and sends signals to, the system interface, the Ethernet interface, and the front panel (see Figure 1.4).A system control bus interconnects the modules and carries alarm and control signaling between the reciter and the other modules. The Ethernet interface carries voice over IP and also allows maintainer access via a web browser.

20 Description TB9400 Installation and Operation Manual© Tait Limited November 2013The reciter carries out signal processing and has overall control of the base station. Its circuit boards are shown in Figure 1.5.The receiver board contains all the receiver circuitry, while the exciter circuitry is located on the transmit forward board.The reciter control board converts information between analog and digital and controls the maintainer’s access via the front panel. It performs the air interface signal processing for digital P25 mode, gives the base station an identity as a network element, and provides the physical connections for the Ethernet and system interfaces.Figure 1.5 Reciter boardsRF InputRF Input(feedbackfrom PA)RF OutputReceiverBoardTransmitForwardBoardTransmitReverseBoardFrontPanelReciterControlBoardMaintainer AccessSystem Inputand OutputEthernet Interfaceto Network
TB9400 Installation and Operation Manual Description 21© Tait Limited November 20131.7.1 Signal PathsFigure 1.6 gives an overview of signal paths within the reciter. Digital P25 signals from the receive RF interface pass through the digital receiver and P25 modem to the control software in the RISC processor. The control software passes the signal through the Ethernet interface to the site controller, or to the central voter in a simulcast system.Input to the Ethernet interface can be from the site controller, or from the central voter in a simulcast system. These inputs are processed by the RISC and passed through the P25 modem to the transmitter. If the base station is itself a central voter, this input can also be a received signal, which is voted on and sent back through the Ethernet interface to the site controller.1.7.2 Online and Offline ModesThe base station normally operates in Online mode, but you can put it into Offline mode via its web interface.Online Mode In Online mode, the base station performs its normal functions. Offline Mode Some procedures, such as activating firmware or running certain diagnostic tests, require the base station to be in Offline mode. This takes the base station out of service. However, the front panel is still operational and can be used in the normal way.

TB9400 Installation and Operation Manual Description 23© Tait Limited November 20131.7.4 Power Management and DistributionThe PMU manages the supply of power to ensure uninterrupted operation of the base station. A range of parameters is monitored and these can trigger alarms that are sent to the reciter. Alarms can be monitored via the web interface and reported via SNMP traps; they are also recorded in the reciter’s internal log file.AC to DC ChangeoverWhen the PMU has an AC and a DC module, the base station can be powered by either the AC (mains) or the DC (battery) supply. The base station will default to the AC supply if both supplies are provided. If the AC supply becomes unavailable, a seamless changeover from the AC to DC supply takes place, providing that the battery voltage is above the configured minimum startup voltage. You can use a web browser to check whether the base station is running on battery or mains power.DC Operation When the base station is running off the DC supply and the battery voltage falls below the configured minimum, the base station will enter battery protection mode to protect the battery and base station equipment. The standby power supply card maintains the power to the PMU microprocessor, while the rest of the PMU is shut down. When the battery voltage rises to the configured startup setting, power is resumed to the DC supply. Refer to “PMU Operation on DC Input” on page 25 for more detailed information.Auxiliary Power ControlThe output from the auxiliary power supply board can be used to power other site equipment. The maximum output is 40W.Distribution Figure 1.8 shows how power is distributed to modules in the subrack. The 28VDC output from the PMU is fed directly to the PA in a single base station, or directly to PA 1 in a dual base station, and to the other modules via the subrack interconnect board. Power to the reciters and front panel is current-limited by self-resetting fuses on the subrack board.The AC converter has a series switch which breaks the phase input to the converter. The DC input, however, has much higher current ratings. Its switch does not disconnect power from the DC converter itself, but disables the converter by switching off its control circuitry.The outputs from both the AC and DC high power converters are added together and fed to the modules via the high-current outputs. The auxiliary output is also tapped off this summed output.

TB9400 Installation and Operation Manual Description 25© Tait Limited November 20131.7.5 PMU Operation on DC InputThe operation of the PMU on DC input is controlled by three sets of parameters:■user-programmable alarms■user-programmable startup and shutdown limits■battery protection limitsThe voltage range for each of these parameters is provided in Table 1.1 on page 26. Figure 1.9 on page 27 illustrates how these parameters interact, and how they control the operation of the PMU over a range of DC input voltages.Alarms User-programmable alarms can be set for low or high battery voltage (Configure > Alarms > Thresholds). The alarms will be triggered when the set voltage levels are reached. These limits are subject to the tolerances of the battery protection circuitry, as stated in “Battery Protection (Fail-safe) Limits” in Table 1.1.Startup and Shutdown LimitsThe user-programmable startup and shutdown limits allow for adjustable startup and shutdown voltages (Configure > Base Station > Miscellaneous). These limits can be adjusted for different numbers of battery cells, or for the particular requirements of the base station operation. Once the limits are reached, the PMU will shut down. These limits are subject to the tolerances of the battery protection circuitry, as stated in “Battery Protection (Fail-safe) Limits” in Table 1.1.Notice It is possible to set the startup voltage of the base station below the nominal voltage of the battery. Continuing to use a battery for extended periods when it is below its nominal voltage will severely shorten its service life. For more information on battery management, we recommend that you consult the battery manufacturer.Battery Protection LimitsThe battery protection limits are set in hardware at the factory, and cannot be adjusted by the user. These limits will not be reached under normal operation conditions, but are provided as “fail-safe” measures to protect the battery from deep discharge. They also remove the need for low-voltage disconnect modules.

28 Description TB9400 Installation and Operation Manual© Tait Limited November 20131.7.6 Front Panel FansThe front panel is equipped with three fans. One fan is for the PMU and the other two are for the reciter/PA pairs in a 50W base station, or for the PA and reciter in a 100W base station. Front panel fans do not operate continuously, but are switched on and off as needed. The PMU and PA control their own fan. Reciters request the front panel to turn on their fan. The reciter in slot 1can also carry out a fan test on all three fans.Front panel fans are 3-wire fans (power, ground, and rotation detect). The reciter can monitor whether the fans are rotating and generate an alarm if the fan fails.The fans turn on for a few seconds when the base station is powered up, and also after the front panel is refitted to a base station which is powered up. Configuring Fan ControlThe operation of the PA fan is configurable via the web interface; you can specify the threshold temperature at which the fan will be turned on, and set the fan to operate only when the PA is transmitting.The PMU fan has fixed on/off thresholds and a defined set of duty cycles based on the PMU temperature and load current, as described in the following table.PMU Temperature Current Fan Duty Cycle<149°F (65°C) <4A4A–6A6A–8A8A–12A12A–14A≥15Aalways off2 minutes on, 8 minutes off2 minutes on, 5 minutes off3 minutes on, 3 minutes off4 minutes on, 1 minute offalways on149–167°F (65–75°C) –– two minutes on, one minute off>167°F (75°C) –– always on

30 General Safety and Regulatory Information TB9400 Installation and Operation Manual© Tait Limited November 20132.1 Personal Safety2.1.1 Unpacking and Moving the EquipmentTo prevent personal injury and equipment damage, we recommend that two people unpack and move the equipment. Caution A subrack complete with modules can weigh up to 55lb (25kg), or up to 62lb (28kg) complete with packaging. We recommend that you have another person help you unpack and move the equipment. The TBAA03-16 carrying handles will make it easier to move the equipment once it has been unpacked. If necessary, remove the modules from the subrack before moving it (refer to “Replacing Modules” on page 99). In all cases follow safe lifting practices.2.1.2 Lethal VoltagesWarning The PMU contains voltages that may be lethal. Refer to the ratings label on the rear of the module.The equipment must be installed so that the rear of the PMU is located in a service access area which is accessible only by qualified personnel. The PMU must be connected to the mains supply source by qualified personnel in accordance with local and national regulations.Disconnect the mains IEC connector and wait for five minutes for the internal voltages to self-discharge before dismantling. The AC power on/off switch does not isolate the PMU from the mains. It breaks only the phase circuit, not the neutral.The PMU should be serviced only by qualified technicians. There are no user-replaceable parts inside. If the PMU is damaged and does not function properly, stop the module safely and contact your regional Tait office immediately.All servicing should be carried out only when the PMU is powered through a mains isolating transformer of sufficient rating.

TB9400 Installation and Operation Manual Working with Base Stations from Your PC 49© Tait Limited November 20134.2.3 Responding to Security WarningsWhen your browser connects to a TB9400 for the first time, it raises a security warning. Normally, secure websites have a security certificate issued by a trusted Certification Authority. This is to foil attempts by rogue websites to pretend to be something they are not. The TB9400 creates a self-signed certificate when the reciter’s firmware is installed. Your browser raises a security warning because the security certificate was not issued by a trusted Certification Authority. The browser has a way of letting you override or bypass the security warning, as explained below. You can be confident that you are not connecting to a rogue website pretending to be your TB9400, so follow the procedure below to tell the browser that the security certificate is OK. The browser then stores the security certificate and will not raise a warning on subsequent connections, unless the IP address of the TB9400 changes. For more information, refer to http://support.microsoft.com/kb/931850 (Internet Explorer) or search for “security certificate” in your browser’s Help. Firefox 1.

TB9400 Installation and Operation Manual Working with Base Stations from Your PC 59© Tait Limited November 20134.4.4 Working with Configuration FilesAt any time, you can save the current configuration settings as a file (Tools > Files > Configuration). This is stored in the base station, but we recommend that you download it and store it on your computer as an off-site backup. The base station identity and network identity are not saved as part of the configuration file.You may want to develop a master configuration and upload it to all base stations in the network. The master configuration can contain all the different channel configurations and can be common to all base stations. The base station identity selects the default channel.Base stations are delivered with a default configuration which provides a safe set of values. We recommend that you download it and store it on your computer as a backup before changing and saving any configura-tion settings.4.4.5 Configuring Single Base StationsMost base stations in non-simulcast trunked networks are single. They interface to a site controller but not to other base stations. The following explains the special considerations when configuring single base stations.Channel Group MembershipAlthough single base stations are not actually part of a channel group, their channel configurations (Configure > Base Station > Channels) must still select a channel group (Configure > Channel Group > Channel Groups). Channel Group IP AddressThe selected channel group must be configured for single base station operation. Specify 127.0.0.1 as the channel group IP address. This stops the base station from attempting to send voice packets to other base stations.Preamble Although the single base station’s transmitter does not receive voice packets from other channel group members, it still receives them from other base stations via trunking controllers. So, while most channel group settings have no effect, the preamble setting still applies and determines how large the transmit buffer is.The default setting of 40ms is intended for internal jitter only. If the base station is a traffic channel, you may have to increase the preamble. Voice arriving at the base station’s trunking interface has travelled from another base station via the trunking site controller and could have significantly more jitter.Marshalling DurationAlthough marshalling duration applies only to control channels, and has no effect on traffic channels, we recommend that you configure the marshalling duration for each base station as described below. This will allow any base station to operate as a control channel when required.
60 Working with Base Stations from Your PC TB9400 Installation and Operation Manual© Tait Limited November 2013Configure the channel group settings to specify fixed marshalling and allow a duration of 40ms. This gives the control channel’s transmitter an appropriate buffer (control channels do not use the preamble to regulate the transmit buffer). Trunking Interface Single base stations need a control connection to their site controller. A single base station interfaces to the site controller in the same way as the master base station in a trunked channel group. Select Configure > Network Interfaces > Trunking to configure this.4.4.6 Configuring Base Stations in a Channel GroupYou can configure the way the base station behaves in its channel group. Also, qualified network engineers can change DSCP assignments, so that routers and switches provide a different quality of service to different types of IP packets.In trunked networks, many base stations are single and not actually part of a channel group. However, they still must be assigned to a channel group configuration and some of its parameters must be set correctly.4.4.7 Setting Up Custom AlarmsEach of the base station’s 12 digital inputs can be used to raise a custom alarm when the input goes high or low. The Custom Alarms form (Configure > Alarms > Custom Alarms) allows you to assign a name to each custom alarm, and to configure whether the alarm is triggered when the digital input goes high or low. Custom alarms are reported via the web interface and SNMP traps.Custom alarms are used to provide an alarm when an external event activates a digital input. You can rename any of the available alarms to provide a more meaningful name, such as “Door open”.4.4.8 Disabling the Front Panel KeypadYou can disable the front panel keypad to prevent access to the base station via the front panel menus. Select Configure > Base Station > Miscellaneous and in the Front Panel area clear the Keypad enabled check box.Notice If you disable the front panel keypad, you cannot use it to find out the base station’s IP address. Make sure that you store the IP address securely and do not lose it.
TB9400 Installation and Operation Manual Working with Base Stations from Your PC 61© Tait Limited November 20134.4.9 Preparing to Download FirmwareNew versions of base station firmware are remotely downloaded to base stations from a package server (a web server application). You can set up a single computer to be the central package server for all the base stations on your network, using a web server of your choice. Tait also provides the Mongoose1 web server as part of the base station firmware package for use with a temporary package server, such as a laptop.The base station firmware package is provided on the product CD, and can also be downloaded as a zip file from the Tait support website.This procedure describes using the Mongoose web server.Installing the Firmware PackageThe installation procedure copies files into a folder and adds items to the Windows Start menu (Start > Programs > Tait Applications > TB9400). From the Start menu you can then access the Help, licenses, manuals and release notes for each firmware package, and also start Mongoose.You do not have to install Mongoose to make it work, because it is a self-contained executable file. Once started, it will run in the back-ground until stopped, or the computer is shut down. Mongoose must also run from the same folder as the firmware files.If you have a product CD:1. Insert the product CD into the CD drive of the package server computer.2. If the CD does not autorun, navigate to the CD’s root folder and double-click TB9400.msi to run the Windows installer.If you are downloading a base station package zip file:1. Save the zip file to a suitable location on the hard drive of the pack-age server computer.2. Extract the zip file, then navigate to the root folder and double-click TB9400.msi to run the Windows installer.Notice Tait recommends that the maximum length of the path to the location of the extracted files is 100 characters. Using a longer path may cause the files to be extracted incorrectly.1. Mongoose runs on Windows only.
62 Working with Base Stations from Your PC TB9400 Installation and Operation Manual© Tait Limited November 2013Setting Up a Central Package ServerIt is beyond the scope of this manual to describe the exact procedure for setting up a central package server for any particular network. Tait expects that each customer will configure their own package server according to the requirements for their network.However, you do need to configure each base station with the IP address and port of the package server computer.1. Log in to the base station and select Configure > Base Station > Miscellaneous.2. Under Package server, enter the IP address and port number of the package server.3. Download the firmware as described in the Help.Notice The base station has enough space for two firmware pack-ages. If the base station already has two packages, delete the unwanted package before downloading another.Setting up a Temporary Package ServerIf you want to use a laptop as a temporary package server, you can temporarily override the package server IP address and port in each base station.1.

TB9400 Installation and Operation Manual Installation 65© Tait Limited November 20135InstallationThis chapter provides information on the site requirements for your TB9400 equipment and also describes how to install the base station in a standard 19 inch rack or cabinet.If this is your first time installing a TB9400 base station, we recommend that you read the entire chapter before beginning the actual installation.
66 Installation TB9400 Installation and Operation Manual© Tait Limited November 20135.1 Before You Begin5.1.1 Equipment SecurityThe security of your base station equipment is a high priority. If the site is not fully secure, the base station should at least be locked in a secure cabinet to prevent unauthorized access.5.1.2 Grounding and Lightning ProtectionElectrical Ground The base station modules are grounded by physical contact between the module case and the subrack. To ensure a good ground connection you must tighten each module retaining clamp securely (refer to “Final Reassembly” on page 110 for the correct torque).A threaded grounding connector is provided on the rear of the subrack for connection to the site ground point (refer to “Connecting Up the Base Station” on page 86 for more details).Lightning Ground It is extremely important for the security of the site and its equipment that you take adequate precautions against lightning strike. Because it is outside the scope of this manual to provide comprehensive information on this subject, we recommend that you conform to your country’s standards organization or regulatory body.5.1.3 Equipment VentilationAlways ensure there is adequate ventilation around the base station. Notice Do not operate it in a sealed cabinet. You must keep the ambient temperature within the specified range, and we strongly rec-ommended that you ensure that the cooling airflow is not restricted.Notice The cooling fans are mounted on the front panel and will only operate when the panel is fitted correctly to the front of the subrack. To ensure adequate airflow through the base station, do not operate it for more than a few minutes with the front panel removed (e.g. for servicing purposes).5.1.4 Ambient Temperature SensorThe ambient temperature reading for the base station is provided by the temperature sensor located on the front panel circuit board.
TB9400 Installation and Operation Manual Installation 67© Tait Limited November 20135.1.5 Cabinet and Rack VentilationThe cooling airflow for the base station enters through the front panel and exits at the rear of the subrack. For optimum thermal performance, the heated air that has passed through a base station must not be allowed to re-enter the air intakes on the front panel. Any space at the front of the cabinet not occupied by equipment should be covered by a blanking panel. Refer to Figure 5.1 on page 68. To allow enough cooling airflow through a cabinet-mounted base station, we recommend the following:■an area of at least 23in2 (150cm2) of unrestricted ventilation slots or holes in front of the air intakes for the fans for each subrack; for example, thirty 0.25x3.3in (6x85mm) slots will allow the recommended airflow■a vent in the top of the cabinet with an area of approximately 23in2 (150cm2) per subrack, or a similar area of ventilation per subrack at the rear of the cabinet behind each subrack■a 2U gap at the top of the cabinet.Notice The ventilation opening must be unrestricted. If the slots or holes are covered with a filter, mesh or grille, the open area must be increased to allow the same airflow as an unrestricted opening.The maximum ambient temperature entering the cabinet must not exceed +140°F (+60°C).If you are installing multiple subracks in a cabinet, ensure that there will be enough cooling airflow through the cabinet after the equipment has been installed. For example, the recommended maximum number of subracks in a 38U cabinet is five, as shown in Figure 5.1 on page 68.If the base station is installed in a rack or cabinet with other equipment with different ventilation requirements, we recommend that the base station be positioned below this equipment. Auxiliary Extractor FansThe base station does not require auxiliary extractor fans mounted in the top of the cabinet. If your cabinet is already fitted with fans, the following procedures apply:■if there are six or more 4.75in (12cm) fans, each capable of extracting 94.2 ft3 per minute (160m3 per hour), they must run continuously■if there are fewer than six fans, you must remove them and ensure the vent in the top of the cabinet has an area of approximately 23in2 (150cm2) per subrack.If you have any other configuration, the performance of your system will depend on how closely you comply with the base station airflow requirements described above.

TB9400 Installation and Operation Manual Installation 69© Tait Limited November 20135.2 Unpacking and Moving the SubrackThe subrack is packed in a strong corrugated cardboard carton with top and bottom foam cushions. To prevent personal injury and damage to the equipment, we recommend that two people unpack and move the subrack. To remove the subrack from the carton, follow the procedure illustrated in Figure 5.2. Caution A subrack complete with modules can weigh up to 46lb (21kg), or up to 53lb (24kg) complete with packaging. We recommend that you have another person help you unpack and move the equipment. The TBAA03-16 carrying handles will make it easier to move the equipment once it has been unpacked. If necessary, remove the modules from the subrack before moving it (refer to “Replacing Modules” on page 99). In all cases follow safe lifting practices.1. Cut the tape securing the flaps at the top of the carton and fold them flat against the sides b.2. Rotate the carton carefully onto its side c and then onto its top d, ensuring that none of the flaps is trapped underneath.Figure 5.2 Unpacking the subrackbegfhicd

TB9400 Installation and Operation Manual Installation 73© Tait Limited November 20135.4 Initial Setting UpBefore putting the base station into service, you may want to carry out some basic functional testing, configuration, and tuning (if required). This section provides an overview of these procedures:■checking that the base station powers up correctly■checking the basic functionality of the base station by using the tests available in the web interface■customizing the configuration for the intended installation and verifying that the configuration is correct■changing the root password■tuning the base station (if required).5.4.1 Confirming OperationNotice Make sure that the RF output is connected to a suitable atten-uator or dummy load. Do not remove the load while the PA is transmit-ting as this may damage the PA output stage.Applying Power 1. Apply power by turning on the PMU.2. Check that the base station powers up correctly:■The front panel display will show “Please wait...” while the base station starts up (this may take up to two minutes). When the startup process is complete, the display will show the home screen.■The cooling fans in the front panel will run at full speed for a few seconds, then run at low speed while the base station starts up, and then assume standard operation. One or more fans may operate, depending on the temperature of the modules.
74 Installation TB9400 Installation and Operation Manual© Tait Limited November 2013Functional Tests The following table provides an overview of the tests available using the web interface.

TB9400 Installation and Operation Manual Installation 75© Tait Limited November 20135.4.2 Customizing the ConfigurationThe following steps provide an overview of the process used to configure the base station with the settings it needs. Refer to the Help for detailed information.1. Log in to the base station (refer to “Connecting Your PC to the Base Station” on page 46 for more details).2. Select Configure. The base station has many different settings that can be configured before it is put into operation, such as:■channel configurations■alarm control and SNMP agent■network interfaces■channel groups and quality of service■channel and signaling profiles■CWID■miscellaneous items such as minimum battery voltages, fan control, NTP and package servers.3. Make the changes needed in each form and click Save.We recommend that you save the configuration to your PC or network. First make a backup copy of the configuration (which is stored in the base station as a file), then save this file to a folder on your PC or network. This provides a backup which can be restored to the base station if the configuration information becomes lost or corrupted.5.4.3 Recommended Configuration SettingsIn a dual base station only reciter 1 communicates directly with the PMU and front panel. Therefore the following configuration settings are recommended for dual base station operation:■Disable the “PMU not detected” alarm on base station 2 (Configure > Alarms > Control > PMU).■Disable the “FP not detected” alarm on base station 2 (Configure > Alarms > Control > Front panel).
76 Installation TB9400 Installation and Operation Manual© Tait Limited November 20135.4.4 Restricted Port NumbersCertain configuration settings in the base station’s web interface require you to enter a port number (for example, the trunking interface and channel groups). Two ranges of port numbers are unavailable for use with the base station. The web interface will prevent you from entering a number from these ranges, as explained below.5.4.5 Changing the Root PasswordThe root password to the Linux operating system of the reciter is a possible security risk. The equipment is delivered with a default password that is well known. Knowledge of the password could be used to render the equipment inoperable, for example by deleting files. If you are concerned about the security risk that this poses, change the password. If Tait provides support services, it may need to know the password.Notice If you change the password and then lose it, the equipment must be returned to Tait. Make sure that you store the password securely and do not lose it. To change the root password, follow these steps.1. Log in from your PC to the base station using SSH client software such as PuTTY. The username is “root” and the default password is “k1w1”. 2. At the # prompt, enter the command “passwd”.3. Follow the on-screen instructions.4. Record the password in a secure location. Restricted Port Numbers Details0 – 1023 The “well-known ports”, commonly used by other devices in a network. Using a port number in this range could cause compatibility problems with other devices.12000 – 14999 Reserved for internal use in the base station. Using a port number in this range could cause the base station to malfunction.
TB9400 Installation and Operation Manual Installation 77© Tait Limited November 20135.4.6 Tuning the ReciterThis section also applies to receive-only reciters.B3-Band Reciter Before the base station is installed on site, you may need to tune the receiver front end. The receiver front end requires tuning if the receive frequency is shifted more than 2MHz away from the previously set frequency, or the RSSI level of the new frequency is more than 1dB lower than the RSSI level of the previously set frequency. The receiver in the B3-band reciter covers the 148 to 174MHz frequency band. This is split into two sub-bands: 148 to 159MHz and 159 to 174MHz. Each sub-band has its own helical filter (shown in Figure 5.3 below) which is electronically switched in or out of circuit depending on the frequency programmed into the reciter. The bandwidth of these helical filters is approximately ±1.5MHz. To check the RSSI level and tune the receiver front end (if required), follow these steps.1. Remove the reciter from the subrack and reconnect the system control bus cable to power up the reciter.2. Log in to the reciter and select Monitor > Interfaces > RF Interface. For information on connecting directly to the reciter, refer to “Connecting a Networked PC to a Base Station” on page 50.3. Feed a signal at the currently tuned receive frequency and at a level of –80dBm into the reciter’s RF input. Check that the RSSI reading on the RF Interface page is –80dBm ±1dB. Note this reading.Figure 5.3 Identifying the B3-band receiver front end helical filters148 to 159MHz159 to 174MHz
78 Installation TB9400 Installation and Operation Manual© Tait Limited November 20134. Set the reciter to the new receive frequency.5. Change the RF input signal to the new receive frequency at –80dBm. Check that the RSSI reading is –80dBm ±1dB. If it is, the receiver front end does not require tuning. If it is not, go to the next step.6. Using the Johanson tuning tool1, adjust the correct helical filter for the new frequency (as shown in Figure 5.3) to obtain a peak RSSI reading. This reading should be within 1dB of the reading at the previous frequency. Adjust the center resonator of the filter first, followed by the two outer resonators (in any order). Each resonator should require approximately the same amount of adjustment when tuning.A change in frequency of 5MHz requires approximately one turn of the tuning slug. If tuning to a lower frequency, adjust the slug in (clock-wise); for a higher frequency, adjust the slug out (counterclockwise). 7. Change the RF input signal and the reciter’s receive frequency to 0.5MHz above and below the required frequency and check that the RSSI reading does not drop by more than 0.5dB from the reading at the required frequency.8. Recalibrate the RSSI at the new frequency (Calibrate > Reciter > RSSI). If you wish to confirm the accuracy of the tuning procedure, carry out a sensitivity measurement at the new frequency.1. Included in the TBA0ST2 tool kit. Also available separately as part num-ber 937-00013-00.
TB9400 Installation and Operation Manual Installation 79© Tait Limited November 2013H-Band Reciter Before the base station is installed on site, you may need to tune the receiver front end. The receiver front end requires tuning if the receive frequency is shifted more than 5MHz away from the previously set frequency, or the RSSI level of the new frequency is more than 1dB lower than the RSSI level of the previously set frequency. The receiver in the H-band reciter covers one of the following frequency sub-bands, depending on the model:■H1 - 400 to 440MHz■H2 - 440 to 480MHz.Both sub-bands use the same helical filter (shown in Figure 5.4 below). The bandwidth of the helical filter is approximately ±5MHz. To check the RSSI level and tune the receiver front end (if required), follow these steps.1. Remove the reciter from the subrack and reconnect the system control bus cable to power up the reciter.2. Log in to the reciter and select Monitor > Interfaces > RF Interface. For information on connecting directly to the reciter, refer to “Connecting a Networked PC to a Base Station” on page 50.3. Feed a signal at the currently tuned receive frequency and at a level of –80dBm into the reciter’s RF input. Check that the RSSI reading on the RF Interface page is –80dBm ±1dB. Note this reading.4. Set the reciter to the new receive frequency.Figure 5.4 Identifying the H-band receiver front end helical filterH-band helical filter

TB9400 Installation and Operation Manual Installation 81© Tait Limited November 20135.5 Installing the Base Station on Site5.5.1 Base Stations for Trunked SystemsWhen installing base stations that are part of a trunked system, it is very important to observe good site engineering rules. This is especially true when the channels are combined into a single antenna. If at all possible, the RF planner should avoid frequency plans in which the Rx to Tx spacing is an exact multiple of the trunked channel spacing, thus forcing Tx intermodulation products to fall outside the Rx channels. Cables and antennas should be of high quality construction. Solid shield heliax type cables are best, but if braided shield cables must be used for short distances, their braids must be silver-plated. When the outputs of more than one transmitter are combined, their voltages add, and the resulting peak envelope power is not simply the sum of their powers, but is equal to the power of one of them multiplied by the square of the number of sources. Cables, components, and hardware must be rated to withstand the peak envelope power.During the commissioning process, all transmitters should be activated together using a diagnostic test tone, while the receiver RSSI is monitored. There should be no perceptible increase in RSSI while the transmitters are active.5.5.2 Equipment RequiredIt is beyond the scope of this manual to list every piece of equipment that an installation technician should carry. However, the following tools are specifically required for installing the base station:■Pozidriv PZ3 screwdriver for the M6 screws used in the DC input terminals on the PMU; M6 (0.25in) screws are also used to secure the subrack to the cabinet in factory-assembled systems■Pozidriv PZ2 screwdriver for the M4 screws used to secure the module retaining clamps, and for the fasteners used to secure the front panel to the subrack■8mm AF spanner for the SMA connectors, and the subrack ground connector.You can also obtain the TBA0ST2 tool kit from your regional Tait office. It contains the basic tools needed to install, tune, and service the base station.

We recommend that you have another person help you unpack and move the equipment. The TBAA03-16 carrying handles will make it easier to move the equipment once it has been unpacked. If necessary, remove the modules from the subrack before moving it (refer to “Replacing Modules” on page 99). In all cases follow safe lifting practices.1. Remove the front panel, as described in “Preliminary Disassembly” on page 101.2. Fit the subrack into the cabinet or rack and secure it firmly with an M6 (0.25in) screw, flat and spring washer in each of the four main mounting holes b, as shown in Figure 5.5.If you need extra mounting security, additional mounting holes c are provided at the rear of the subrack for auxiliary support brackets.Figure 5.5 Subrack mounting pointsbmain mounting holes - front cauxiliary mounting holes - rearfront viewrear viewbc

TB9400 Installation and Operation Manual Installation 87© Tait Limited November 20135.6.2 Connecting AC PowerThe PMU is designed to accept a mains input of 88 to 264VAC at 45 to 65Hz. A standard 3-wire grounded socket outlet must be used to supply the AC power. The socket outlet must be installed near the equipment and must be easily accessible. This outlet should be connected to an AC power supply capable of providing at least 600W. The requirements of two typical AC supplies are given in the following table.Your base station should come supplied with a power supply cord to connect the male IEC connector on the PMU to the local AC supply. The pins of the IEC connector on the PMU are identified at right.Nominal Supply Current Requirementaa.

TB9400 Installation and Operation Manual Installation 89© Tait Limited November 20135.6.4 Connecting the Auxiliary DC Power OutputThe PMU can provide an auxiliary DC output from the auxiliary power supply board. This board is available with an output of 13.65VDC, 27.3VDC, or 54.6VDC (depending on the model), and is current limited to 3A, 1.5A or 750mA respectively. This power supply is permanently on as soon as the base station has finished powering up, and is available on the auxiliary output connector on the rear panel.You can connect multiple auxiliary power supply boards in parallel for redundancy purposes, or to provide an output greater than 40W. Although no active current sharing is used, auxiliary boards connected in parallel will current-share before reaching their power limit. The failure (or switching off) of one auxiliary board will not load any other paralleled auxiliary boards in the circuit.The auxiliary power supply turns off briefly when the PMU restarts after a firmware upgrade. This interruption may also cause any ancillary equipment powered from the auxiliary supply to restart. If this is a prob-lem for your system, we recommend connecting auxiliary power supply boards in parallel to ensure an uninterrupted power supply for the ancil-lary equipment.Auxiliary DC Power Output CablingNetwork elements are supplied with a connector, as shown in Figure 5.11. You can use this to connect the PMU’s auxiliary DC power output to another device (refer to “PMU Auxiliary DC Output” on page 111 for the pin allocations).Contact your regional Tait office for details on the full range of wiring kits available.Figure 5.11 Auxiliary DC power connectorPhoenix MVSTBR2.5HC/2-ST/5.08 female
90 Installation TB9400 Installation and Operation Manual© Tait Limited November 20135.6.5 Connecting RFNotice Do not remove the load from the PA while it is transmitting as this may damage the PA output stage. Before disconnecting any RF cables, put the base station into Offline mode to prevent any transmis-sions.The RF input to the base station is via the marked BNC connector on the rear panel of the reciter. The RF output is via the N-type connector on the rear panel of the PA (refer to Figure 5.9 on page 86).Cables and antennas should be of high quality construction. Solid shield heliax type cables are best, but if braided shield cables must be used for short distances, their braids must be silver-plated.Recommendations for Installing the PAWe recommend the following installation procedures, which should protect the PA from damage under all but the most extreme operating conditions.1. Do not connect the PA directly to the antenna. Fit an isolator or duplexer between the PA and the load. Fit the isolator as close as pos-sible to the RF output connector on the PA. Do not connect any switching equipment between the isolator and the PA, unless the switch cannot operate while there is RF present (i.e. the base station is transmitting).2. Fit a surge suppressor to the antenna cabling where it enters the building.3. Inspect all cables and equipment connected to the base station for defects.Ice on the antenna, or a broken antenna, is unlikely to cause damage to the PA. Explanation The circuit design of the PA protects the circuitry from high VSWR. This makes it difficult to damage the RF power device by keying the PA into a mismatched load, or if the load deteriorates over even a short period of time (milliseconds).However, it is possible to damage the device if all the following conditions happen at the same time:■there is a step change in the PA load (for example, the load is removed)■the PA is transmitting■the feed line loss between the PA and the mismatch is <1dB.The effect of such conditions is variable: some devices will not be destroyed, and some may fail after repeated load interruptions.
TB9400 Installation and Operation Manual Installation 91© Tait Limited November 20135.6.6 Connecting an External Frequency ReferenceFor K4 Band, the internal frequency reference accuracy is inadequate, and an external reference must be used. An external reference is also required for simulcast. The external reference frequency can be 10MHz or 12.8MHz, with an input level of 300mVpp to 5Vpp. The stability of this reference should be better than 50 parts per billion (for non-simulcast) or ≤1 part per billion (for simulcast). The reciter automatically detects the frequency of the external reference and configures itself accordingly.If an external reference is required, enable the external reference “Absent” alarm (Configure > Alarms > Control).Use a 50Ω coaxial cable (RG58 or RG223) to connect the external reference to the base station’s external reference frequency input. You can daisy-chain up to eight base stations using F-junctions. The maximum overall cable length is 30m. Terminate the last connection with a 50Ω load.

92 Installation TB9400 Installation and Operation Manual© Tait Limited November 20135.6.7 Connecting a 1PPS SourceA 1PPS signal is required for simulcast base stations. Use a 50Ω coaxial cable (RG58 or RG223) to connect the source to the base station’s 1PPS input. You can daisy-chain up to eight base stations using F-junctions. We recommend that the cable length between the first and last load is kept to a minimum. This will reduce any propagation variation between base stations. The maximum overall cable length is 30m. Terminate the last connection with a 50Ω resistor, otherwise reflections of the 1PPS pulse may occur. A 1PPS signal will be required for all base stations operating in a P25 Phase 2 system. If you intend to upgrade TB9400 base stations to P25 Phase 2 operation at a later date, we suggest that you provide the 1PPS source, or at least the necessary cables, at the time of installation.5.6.8 Ethernet ConnectionThe RJ-45 socket on the reciter’s rear panel provides the 10BASE-T or 100BASE-T Ethernet connection to the other devices in the network. Use Cat-5 cable to connect this socket to the Tait P25 Network via a router or switch. If necessary, refer to “Ethernet Connector” on page 111 for a list of Ethernet connection pin allocations.Figure 5.13 Daisy-chaining a 1PPS inputThe longest length of cable must be between the source and the first base stationuse short lengths of cable between each base stationmaximum of eight base station loads on one 1PPS output50 Ω termination

TB9400 Installation and Operation Manual Maintenance 95© Tait Limited November 20136 MaintenanceThe base station is designed to be very reliable and should require little maintenance. However, performing regular checks will prolong the life of the equipment and prevent problems from happening.It is beyond the scope of this manual to list every check that you should perform on your base station. The type and frequency of maintenance checks will depend on the location and type of your system. The checks and procedures listed below can be used as a starting point for your maintenance schedule.Performance ChecksWe suggest you monitor the following operational parameters using the web interface:■VSWR■DC input voltage, especially on transmit■any temperature alarms.These basic checks will provide an overview of how well your base station is operating.Reciter We recommend that you calibrate the reciter after three months of operation, and then annually for H-band reciters, or every three years for B3-band reciters. The calibration procedure is described in the Help (Calibrate > Reciter > Internal reference), and requires a calibrated frequency generator.PA There are no special maintenance requirements for the PA.PMU There are no special maintenance requirements for the PMU. However, we suggest that you periodically check that the screws on the DC input terminals are tightened to the recommended torque of 18–20lbf·in (2–2.25N·m). They may work loose with thermal cycling. Also, if you are using battery back-up, you should check the batteries regularly in accordance with the manufacturer’s recommendations.Ventilation The base station has been designed to have a front-to-back cooling airflow. We strongly recommend that you periodically check and maintain the ventilation requirements described in “Equipment Ventilation” on page 66 to ensure a long life and trouble-free operation for your base station. Also check for a build-up of dust in and around the module heatsink fins, front panel air intakes, and fan ducts.
