5 GENERAL SYSTEM OVERVIEW: (refer to drawing 50483-01-19) In an off-the-air to radiating cable system, signals received from the air are rebroadcast onto the cable. Signals received on the cable are rebroadcast over the air, e.g., talk-in, talk-out. In an off-the-air to radiating cable multiple Channel Booster application, the PBBA is utilized to enhance the performance of the talk-out in long cable systems. In general, the forward channel, talk-out signals are generated from lower power sources, e.g., handheld transceivers.
6 PROGRAMMABLE BI-DIRECTIONAL BOOSTER AMPLIFIER OVERVIEW: (refer to figure 1) The Programmable Bi-directional Booster Amplifier (PBBA) is a software-driven user-configurable unit for use in a multi-carrier low signal-level environment. It is capable of eight (8) carriers and a composite power of –20dBm. The forward channel covers 100 to 2000MHz and within this band a bandpass filter defined window called the In-Band has a user settable gain. The factory default setting is 20dB. The Out-of-Band gain 0dB. The reverse channel covers 100 to 2000MHz and utilizes passive components/elements to pass these frequencies. This channel has fixed insertion loss due to the passive components/elements. The forward In-Band channel uses a broadband attenuator/amplifier module in which the attenuation is digitally set via computer interface. The forward In-Band channel has a high gain amplifier chain and a band pass filter to boost a specific window of frequencies within the 100 to 2000MHz frequency of operation. Its small package and light-weight allows the user to conveniently install the unit. Indicator lights allow the user to determine the status of the unit from a distance. A user-friendly software enhances the unit’s performance and user interface.

10III. INSTALLATION The Programmable Bi-Directional Booster Amplifier is housed in a steel NEMA 4 enclosure. The enclosure has four mounting tabs on its rear surface (refer to drawing 50483-05-17).In selecting a mounting surface, the size and weight of the unit must be considered. The RF cables to the radiators (distribution system) are connected to female N-connectors on the bottom of the enclosure. Special care should be taken in the dress and separation of theses cables to prevent signal coupling between the input and output of the PBBA. The PBBA requires a 110VAC power source. It is recommended, to maintain the integrity of the NEMA enclosure, that the AC power should enter using conduit or a connector. A cutout for a ¾” conduit connector is provided at the bottom of the enclosure. Connect the unit as follows: RF CABLE CONNECTIONS (refer to drawing 50483-01-18): 1) Talk Out: to radiating cable run to 8-Channel Booster Amplifier. 2) Power: to AC conduit. 3) Com Port: for calibration only no connection required at installation. 4) Talk In: to radiating cable run to end of tunnel. AC POWER INTERCONNECT (refer to drawing 50483-01-15): The AC power signals are connected to an internal terminal block. The terminal block is located on the top plate assembly at the right of the lower edge. Connect the AC sources as follows: 1) The ground wire from the AC conduit connects to terminal 1. 2) The AC high wire from the AC conduit connects to terminal 2. 3) The neutral wire from the AC conduit connects to terminal 3.
11IV. OPERATION OF EQUIPMENT The PBBA requires no operator settings or operation. It is designed for unattended operation. The following is all that is necessary for operation: INSTALL CONNECT TURN-ON WATCH LED
12V. MAINTENANCE SCHEDULE The Programmable Bi-directional Booster Amplifier is designed for unattended operation requiring minimal maintenance. General maintenance consists of equipment inspection an operational tests. Periodical equipment tune-up and alignment is recommended. Cable Inspection: The external and internal cables and connectors should be checked for indication of corrosion. Enclosure Inspection: The interior of the enclosures should be inspected for evidence of condensation. LED Inspection: Power LED: ON Status LED: Flashing at a rate of 1Hz Com LED: OFF The performance of operations testing is recommended to be done bi-yearly. Operational testing will indicate equipment status determining if an alignment is necessary.
13VI. THEORY OF OPERATION The PBBA is a broadband bi-directional amplifier. It has two channels, one is the Forward In-Band and the other is Forward Out-of-Band/Reverse. The Forward In-Band channel has a high gain amplifier chain and a band pass filter. This channel boosts the signals that come through the filter. These are the inbound signals. Above and below the filter passband are the outbound signals which are within the 100 to 2000 MHz range and are handled by the other channel. The Forward In-Band channel uses a broadband attenuator/amplifier module which has a 15dB dynamic range and a gain of around 20dB at 0dB attenuation setting. The attenuation, therefore the overall module gain/loss, is digitally set via computer interface. The Forward Out-of-Band/Reverse channel covers the frequency range of 100 to 2000 MHz. Due to the configuration of this channel it has a fixed insertion loss. With the two channels integrated, the unit provides bi-directional amplification of inbound signals.
14VII. TROUBLESHOOTING PROBLEM SOLUTION ON-SITE-REMEDY 1) Power Indicator is off a) Check of the unit is plugged into a 120VAC source. b) Check if the internal circuit breaker on/off switch is depressed Plug in the unit to 120VAC or depress internal circuit breaker. 2) Power indication on but status light is not blinking Check connection to the microprocessor board Microprocessor board fault. Pull out for repair 3) a) Com port does not light up when unit is programmed Check serial cable connections 4) Unit does not respond when programmed Check serial cable connections 5) Unit does not provide designed gain or unit does not have gain at all or intermittent operation a) Check RF connection between modules b) Check Talk In/Talk Out RF connections
