50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 9 SECTION I INSTALLATION INTRODUCTION AeroComm strongly recommends that the user install the two rack enclosures for the system by bolting them down onto level concrete flooring. The user must equip the concrete floor with appropriate anchors and drill the floor of the cabinet to match. AeroComm recommends stainless steel wedge anchors with a minimum diameter of 3/8” and a thread length of 2 ¼”. The hole pattern in the concrete floor and in the floor of the cabinet should be arranged such that the anchor studs are centered 2” from each wall of the cabinet in each of the four corners. WARNING FAILURE TO SECURE THE CABINET AS RECOMMENDED MAY RESULT IN CABINET TIP-OVER DURING INSTALLATION OF THE POWER SUPPLIES. AeroComm recommends installing the two cabinets 3 feet apart. This separation distance provides easy access to the sides and top of each cabinet; additionally, this separation provides necessary RF isolation of the two units. Under no circumstances should the two units be located more than 10 feet from one another; separation distances greater than 10 feet will increase path loss on the RF cables connecting the two units and result in non-optimal operation. DETAILED INSTALLATION INSTRUCTIONS MECHANICAL INSTALLATION OF THE CABINETS Determine the bolt pattern to be used for anchoring the two cabinets. Install anchors in concrete floor & match drill cabinet floors. Position cabinets over the floor anchors and fasten the cabinets to the floor. WARNING ENSURE AC POWER SERVICE LINES ARE NOT LIVE PRIOR TO CONNECTING TO THE EQUIPMENT CABINETS.

50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 28 The Eight-channel, Bi-Directional 800 MHz-Band, RF Distribution Amplifier system requires no regular operator intervention to perform its function. The system is accompanied by two software programs, the User’s software and the Technician’s software. All adjustments to the system are made using these software packages. The User’s software allows the operator to change channel frequencies, channel time-out settings, and channel keying mode. The Technician’s software provides the user with the ability to perform maintenance actions; this software is described in detail in the maintenance section. Given that the channel settings provided by the factory are satisfactory and the system performs without any trouble, no adjustments need be made. If any troubles are suspected, the front of the cabinet should be opened and the indicator lights observed. For normal operations, the indicator lights should be as follows: Battery Status Panel – 3 green LEDs on steady Power Supply / Charger Panel – 3 green LEDs on steady Channel status may be determined by observing the indicator LEDs on the channel modules. Possible LED illumination patterns are shown in Figure 16 below for both normal and failure modes. Figure 16. Channel Module LED Indicator IllFigure 16.

The user’s software is designed to run on a Windows-based Pentium PC or laptop. A serial cable must be connected between the computer’s COM1 port and the PROGRAM port on the front of the channel being adjusted. The channel must be powered up in order to be programmed. A brief discussion of the functions is provided here; details of actually affecting the desired changes are presented in the User’s Guide.
50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 29 CHANGING THE TIME-OUT DURATION The time-out duration is how long a channel can be held open (keyed on) for a retransmission. This feature prevents a channel from being disabled by an inadvertent or intentional “key and hold” action without any voice communication. The time-out duration can be up from 1 second to 99 minutes 59 seconds in 1 second intervals. The time-out duration can be disabled by setting it to 00 minutes 00 seconds. When disabled, the channel will key continuously with the presence of a received signal. CHANGING THE MODE SETTING The channel mode may be set to either CONTINUOUS or RSSI (Received Signal Strength Indication). In the continuous mode, the channel is always keyed and continuously transmitting. In the RSSI mode, the channel is keyed only when the incoming signal strength is above the factory set threshold level. Normal operation will be in RSSI mode; continuous mode is normally used only for testing. The factory-set RSSI threshold level is –90dBm. If regular traffic is below this level, call the factory to arrange for adjustment of this threshold level. If the ambient noise on the channel is above this level, refer to the Technician’s Guide on how to set the attenuation to overcome this. TECHNICIAN’S SOFTWARE The Technician’s guide for using the software is provided in Section VII. A brief discussion of the functions are provided here; details of actually affecting the desired changes are presented in the Technician’s Guide. SETTING THE ATTACK TIME Changing the attack time adjusts the time interval allowed between a transmission keying off and a subsequent transmission keying on. This feature is designed to provide the system operator with the ability to minimize an attacker’s ability to disable a channel by repeatedly keying a radio. The attack time is adjustable in 50 millisecond intervals from 50 milliseconds to 4.9 seconds. CHANGING THE INPUT ATTENUATION The input attenuation control serves two purposes. First, it can be used to reduce the ambient RF noise level below the channel module’s threshold key level. This must be adjusted incrementally until the noise floor is below the threshold, while the intended signal still has enough level to key the booster amplifier on. Second, if the intended signal is unusually high, the attenuation control can be use to “trim” the signal level down to minimize the channel’s IM products which may interfere with adjacent channels.

50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 31 SECTION III MAINTENANCE BDA MAINTENANCE: The 8 Channel Booster Amplifier, BDA, is designed for unattended operations requiring minimal maintenance. General maintenance consists of the cleaning/replacement of the intake/exhaust filters, equipment inspection and operational tests. It is recommended the routine maintenance be accomplished monthly and the schedule revised to meet the requirements of your unique installation. Equipment tune-up and alignment is required only if indicated by the operational tests. AIR FILTRATION: The intake and exhaust air filters should be periodically checked and cleaned. The two filter grills (on the enclosure’s top and front door) are easily removable; access to the interior of the enclosure is not required. When required, use only aluminum filter replacements. CABLE INSPECTION: The exterior cables and connectors should be periodically inspected for evidence of corrosion. ENCLOSURE INSPECTION: The interior of the enclosures should be inspected for evidence of condensation. The internal cabling should be inspected. In addition, the operation of the cooling fan should be tested. OPERATIONAL TESTS: Operational testing may consists of keying up each channel with a handheld. The performance of the BDA will indicate if more detailed test are required. The maintenance schedule should take in consideration the environment of the installation a performance of the BDA. The inspection and cleaning of the air filters should be preformed monthly. In general, all recommended maintenance should be preformed tri-monthly. BATTERY MAINTENANCE (BACKUP BATTERY): It is recommended that the inspection of the condition and maintenance of the user supplied batteries should be performed as prescribed by the battery manufacture.

50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 33 SECTION V THEORY OF OPERATION THEORY OF OPERATION The eight channel bi-directional amplifier uses 16 channels of synchronized down-up conversions. The multi-channel booster is divided into two independent 8-channel systems (8 high band and 8 low band) for full duplex operations. Inbound signals, talk-in, are received at the roof antenna, 8 selected frequencies are processed (filtering and amplification), and rebroadcast on radiating cable. Conversely, outbound signals induced onto the radiating cable are similarly processed and rebroadcast on the roof antenna. The 8 talk-in channels are the high band signals (864-869Mhz), and the 8 talk-out channels are low band (819-824Mhz). Each system consists of a duplexer, LNA/8-way splitter, 8 channel modules (down-up converters with synthesized LOs), 8 class C RF power amplifiers with an 8-way power combiner. In addition there are internal power supplies for 110vac operation, provisions for connecting to and charging external batteries for battery back-up operation, and a thermostat controlled cooling fan. The RF signal flow of the two systems are identical. RF band pass filters internal to the system modules determine high band or low band operations. (Refer to Figure 19).

50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 36 DUPLEXER: The duplexer allows for full duplex operation, simultaneous transmit and receive into a common antenna port. The pass/reject filtering of the duplexer provides band pre-selection, minimal insertion loss between the antenna port to the two ports, transmit and receive ports, and provides high isolation between the transmit and receive ports. For proper operations, the talk-in booster amp, BA, is connected to the roof antenna, and the talk-out BA to the radiating cable. Duplexer configuration as follows: TALK-IN BA: Through a type N connector on the top of the enclosure, the antenna port of the duplexer is connected to the roof antenna. The receive port is connected to the BA’s LNA/8 way splitter for processing of the inbound signals. Through a type N connector on the top of the enclosure, the transmit port is externally cabled to the RF output port of the talk-out BA to broadcast the outbound signals on the roof antenna. TALK-OUT BA: Through a type N connector on the top of the enclosure, the antenna port of the duplexer is connected to the radiating cable. The receive port is connected to the BA’s LNA/8 way splitter for processing of the outbound signals. Through a type N connector on the top of the enclosure, the transmit port is externally cabled to the RF output port of the talk-in BA to inject the inbound signals onto the radiating cable. LNA/8-WAY SPLITTER: The LNA/8-way consists of two modules, a low noise amplifier, to provide band pre-selection and amplification of the received signal, and an 8-way splitter. In the LNA module, the operational band is selected by two 5 pole ceramic band pass filters. For low band operation, filters centered at 821.5, with a bandwidth of 5Mhz are installed; for high band operation, filters are centered at 866.5Mhz are installed. The 8-way splits the LNA output to the inputs of the 8 channel modules. Splitter output port: “1” to the input of channel module “1” “2” to the input of channel module “2” etc. Through channel 8. CHANNEL MODULE (IF MODULE): The CHANNEL MODULE consists of three components; an IF module (a synchronized down-up converter to provide a high degree of filtering and hard limiting of a channel frequency), a micro-controller (to monitor and control the IF module), and a motherboard (to route signals to the back panel of the channel module chassis).
50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 37IF CHANNEL MODULE: The IF module consists of 5 compartments: • The RF amplifier provides for additional channel pre-selection of the received RF signal. • The down conversion of the signal received to an IF of 90Mhz, two cascade crystal filters provides a high degree of filtering • The hard limiting of the IF eliminates the requirements of an AGC loop. An analog RSSI from the IF is compared to a threshold setting to produce a logic output, RSSI KEY. This signal is monitored by the micro-controller to produce the key line and key line time-out functions. Keying the final stages of the IF module and the final RF power amplifier prevents unwanted spurious outputs when no sign carrier is detected. • The up conversion and filtering to the original frequency. With hard limiting at the IF frequency, a constant output level verse the input level is produced. • A dual output synthesized LO. Synchronized conversions mean that the frequency received equals the frequency transmitted. The synthesizer output (Fc+90Mhz) determines the channel frequency and is programmable in 12.5Khz steps to produces the 25Khz channel spacing over the pre-selected band. The mother board in the MACS slot of the card cage provides a 8Mhz common reference oscillator to all the PLLs in the channel modules. MICRO CONTROLLER: The controller performs 4 functions: • Programs the IF module synthesizer to the desired frequency and monitors lock detect for a fault detection. • Monitors the IF’s RSSI KEY and generate the key line function. • Performs the key line time out and delay functions, of the time-out timer. • Interface to the operator. Using a computer and AeroComm’s proprietary software, the operator can program the channel frequency and time-out functions. The software runs on Windows 95, 98, NT or 2000. THE MOTHERBOARD: The IF module and micro controller are configured as plug in modules. The mother board routes the power and control signal between the modules, to the front panel LEDs and RS232 connector and the card cage back panel. RF POWER AMPLIFIER/8-WAY COMBINER: The final RF power amplifier consists of a pre-driver amplifier stage and a hybrid class C RF power module. The pre-driver adds additional filtering the channel modules output, and amplifies to a sufficient level to drive the power amp. To shut-down the power amp, the pre-drive amplifier is controlled (on/off) by the micro-controller output, key line, from the associated channel module. To produce the required per carrier output level after the power combiner, the low band channels utilize a 6 watt RF power module, and the high band requires a 20 watt module. The outputs of the 8 RF power module both low and high are summed by the 8-way combiner.
50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 38 DC POWER DISTRIBUTION/BATTERY BACKUP: The DC power requirements of the channel modules and their associated RF power amplifiers are distributed among multiple power ‘banks’ (VCC1, VCC2, and VCC3). Dividing the power requirements among multiple power supplies prevents a complete shut down due to ‘a’ power supply failure. In addition, it allows for an effective switch over to battery operations. (Refer to Figure 20): The BA is configured with up to 3 power supplies. The power distribution panel unit, PDU, consists of 7 relays to switch between the internal power supplies and external batteries during an interruption of the AC source. For redundancy, for each required VCC voltage, two relays are wired in parallel. . The external batteries are wired into the BA’s battery status panel through 2 pins of a 4 pin connector located on the top of the enclosure (battery input). On the battery status panel, 3 circuit breakers split the battery service for each VCC voltage required. The power supplies and battery bank switches (circuit breaker) are paired as follows: PS1 with battery switch ‘Bank 1’ to supply VCC1. PS2 with battery switch ‘Bank 2’ to supply VCC3. PS3 with battery switch ‘Bank 3” to supply VCC2. To minimize the interruption of the BA operations during switch over to batteries, the 8 channel’s micro-controllers and synthesizers are on a UPS. The UPS voltage source is supplied by diode ‘OR’ing the DC supplies and the bank switch 3 (external batteries) across the 7th relay of the PDU. NOTE: TURN OFF THE BA, FIRST TURN OFF THE 3 BATTERY BREAKERS (PULLED OUT). This prevents the switch over to battery back during shut down procedures. THE HIGH BAND BA: (20 watt RF power modules) (refer to Figure 21): In the high band (talk-in) BA, 3 power supplies are required. The channel modules and their associated RF power modules are distributed between the 3 VCC sources as follows: Channels 1, 2, and 3 to VCC1 Channels 4, 5, and 6 to VCC2 Channels 7 and 8 to VCC3 THE LOW BAND BA: (6 watt RF power modules)(refer to Figure 22): In the low band (talk-out) BA, 2 power supplies are required. The channel modules and their associated RF power modules are distributed between the 2 VCC sources as follows: Channels 1, 2, 3 and 4 to VCC1 Channels 5, 6, 7 and 8 to VCC3
50289-BDA USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE RESTRICTION ON THE TITLE PAGE OF THIS MANUAL 39 In the low band BA, due to the requirements of only two power supplies, the ‘3 state’ battery charger is installed. The output of the battery charger is wire directly to a second pair of pins of the ‘battery input’ connector (located on the top of the enclosure). The output of the charger is terminated directly at the batteries; there are no internal connections between the charger to the battery status panel or PDU.
