D044-13432 Rev A 1 Chapter 1 Theory of Operation 1 Introduction This manual contains information and procedures for installation, operation, maintenance, and troubleshooting of the LNKF100 Modules. The manual is organized into the following chapters: Chapter 1 Theory of Operation Chapter 3 Antenna Installation Chapter 2 Operation Chapter 4 Return for Service 1.1 Overview A LinkNet FM Module is a radio repeater that simultaneously receives and transmits a single narrow band radio channel. The normal application of a LinkNet FM Module is as an on-frequency repeater where the input and output are on exactly the same frequency. It can also be used as a frequency translating repeater where the input and output can be set to any frequency in the specified band (see Table 1 for details). The LinkNet FM Module accomplishes its repeater function without store and forward circuitry, or expensive conventional simulcasting techniques. The fact that the same frequency can be retransmitted by a LinkNet FM Module means that additional frequency allocations are not required in situations where an existing radio coverage pattern needs to be extended. The most common LinkNet FM Module applications are the extension of above ground signals into buildings, tunnels, vehicles or the extension of radio coverage patterns into outdoor shaded areas such as deep valleys. From an applications standpoint, a LinkNet FM Module is very similar to a regular two-way radio repeater. LinkNet FM Modules can be combined using regular two-way radio multicoupling or duplexing equipment and have input and output signal characteristics to those of regular transmitters and receivers. The one special consideration in LinkNet FM Module systems is that of input to output antenna isolation. This must be carefully engineered for each installation. LinkNet FM Modules are designed for indoor use only and are intended for mounting in a standard EIA 19 inch rack. The Modular design of LinkNet FM Module circuitry allows for easy servicing, stocking of spares, adaptability and upgrade ability. 1.2 Models Table 1 LNKF100 Module Family LNKF100 MODULE FAMILY MODEL TYPE FREQUENCY LNKF100-A1 25 KHz FM Channels 136-157 MHz (FM) LNKF100-A2 12.5 KHz FM Channels 136-157 MHz (FM) LNKF100-B1 25 KHz FM Channels 155-174 MHz (FM) LNKF100-B2 12.5 KHz FM Channels 155-174 MHz (FM)

D044-13432 Rev A 5 Chapter 2 Operation 2 Introduction This chapter contains information for the standard operation of the LNKF100 Modules. 2.1 Software Set-Up The LNKF100 module is shipped with the following factory set options: Table 3 LNKF100 Factory Set Options OPTION RANGE OF VALUES DEFAULT VALUE Frequency See Model Chart Order Specific Receive Threshold –110 to -50 dB -95 dB Receive Hysteresis 1 to 10 dB 3.0 dB Time Out 1 to 600 Seconds, or none None Module Enabled On / Off On Transmit Power Level 20 to 37 dBm Order Specific Default values may be changed when an order is placed. Check your order confirmation (shipped with modules) for customized values. 2.2 Configuration In line with the versatility of the LinkNetTM Platform, it is possible to reconfigure the LNKF100 module in the field, either with a Personal Computer (PC) or via the optional Control Module. To use a PC it is necessary to have a Powerwave CAB000000057 control cable to connect between the appropriate module's DB15 connector on the back of the card-cage and the standard DB9 RS232 connector on the PC. On the PC a terminal emulation program such as HyperTerminal is used to communicate to the LinkNet Module. The settings are 9600 baud, 8 bits, no parity, and 1 stop bit. Commands are one or two words followed by pressing Return. Commands may be given in upper or lower-case. Available commands are: ACCESS USER: Required as a simple password to gain access to customer settable parameters and diagnostics. This will time-out after 10 minutes, and may have to be re-typed. HELP or ?: Displays a list of available commands. LIST: Displays current settings and status faults, etc. VER: Display the current version of software. ENABLE 1 or 0: Enables or disables the module. TXFREQ #########: Displays or sets the current transmit frequency (in Hertz). RXFREQ #########: Displays or sets the current receive frequency (in Hertz). TXPOWER ###: Displays or sets the transmit power level (in tenths of a dBm). RXTHRESH -####: Displays or sets the receive threshold level (in tenths of a dBm). RXHYSTER ##: Displays or sets the receive hysteresis (in tenths of a dB). TIMEOUT ####: Displays or sets the timeout-timer value (in Seconds). Enter 0 for no timeout. TESTOSC 1 or 0: Enables or disables the test oscillator. Please consult Powerwave Technologies Inc. for further support.

Power On Self Test (POST) 6 D044-13432 Rev A 2.3 Power On Self Test (POST) Each module automatically performs a self-diagnostics when inserted into the system card-cage. These tests determine that the unit is correctly installed in the card-cage and not damaged in transit. • • • • • • • • All six of the LED’s on the front panel will flash 3 times If the LED’s do NOT flash three times, then remove the module, check the power source, and re-insert the module, (See Installation Instructions). If the card is “OK” the LED’s will continue normally (See Normal Operation). If there is a fault, then the Red Fault LED will remain on. If this occurs, contact Powerwave Technologies Inc. Note! The Power On Self Test is Not an RF test, it only verifies that there is power to the unit and that the logical circuitry is functioning. 2.4 Fault Indications Each module continuously performs internal diagnostics. If a problem is detected it will activate its Red Fault LED and Fault Relay. Faults detected include: Over Temperature High VSWR Loss of Lock Misc. Internal Faults Detailed faults are detected by the optional gateway module. Details may also be determined via the module's control port connector and an RS232 connected Terminal Emulator using the LIST command.

Normal Operation 2.5 Normal Operation The LNKF100 Module has six LED’s on the faceplate: OPERATING - LED will flash GREEN when RF Data is present and unit is operating normally. STANDBY – Under the control of the Control Module, the LNKF100 Module has the ability to act as a duplex transmitter, sitting perpetually in stand by mode waiting for the primary transmitter to fail. This LED should be constant Amber. If a fault should occur with the primary module, the “Stand by” unit will immediately become the primary unit, at which time the stand by LED will be turned off and the LED’s will show an operating module. TRANSMIT – Green when a signal is being transmitted. RECEIVE – Green when a signal is being received. PROGRAM – Constant Amber when the unit is being re-programmed by the controller module. This will signify that the unit is powered on but unavailable for use. FAULT – Constant Red if the internal diagnostics for the module detects a problem. Figure 2-1 LNKF100 Faceplate D044-13432 Rev A 7

Simplex Operation 2.6 Simplex Operation • For back-to-back Simplex operation, the LinkNet Modules to be used MUST be interconnected as shown: Figure 2-2 LNKF100 Simplex Interconnection • • This connection is made using a custom male DB15 to male DB15 cable as shown above interconnected between the two LNKF modules. This cable is plugged into the two module's control ports (see DCM000000008 "Control Connections") on the back of the chassis they are installed in. The RF connections are made using either combiners or RF Relays: DOWNLINK LNKF MODULEUPLINK LNKF MODULERF RELAYSCOMBINERS OR COMBINERS ORRF RELAYSDONOR DISTRIBUTION Figure 2-3 LNKF100 RF Connection • The specific details are determined by the system design, and must provide enough RF isolation between the two modules. 8 D044-13432 Rev A

D044-13432 Rev A 9 Chapter 3 Antenna Installation 3 Introduction This chapter contains antenna installation and warning information for the LNKF100 Modules. 3.1 Antenna Installation • • • • • All antenna installation to be performed by qualified technical personnel only. Antenna installation instructions and locations below are for the purpose of satisfying FCC RF Exposure Compliance requirements. Note! If multiple LinkNet™ Modules are used, the Instructions below apply to the composite power output of all Modules when transmitting simultaneously. The Roof Top Antenna or Antennae for linking to the Donor Site(s) is/are directional (high gain) Antennae, fixed-mounted physically on the side or top of a building, or on a tower. The Antenna Gain must be no more than 20 dBi. Note! If multiple LinkNet™ Modules are used with output combiners into any one Antenna, and/or multiple Antennae are used on one Roof Top, then the sum of composite powers into all Roof Top Antennae must not exceed 20 Watts maximum. The Roof Top Antennae location should be such that only qualified technical personnel can access it, and that under normal operating conditions no other person can touch the antenna, or approach within 10 meters of the antenna. The In-Building Antenna connection is via a coaxial cable distribution system with signal taps at various points connected to the fixed-mounted Indoor Antennae. The Indoor Antennae are simple 1/4 wavelength (0 dB Gain) types. They are used with Powerwave Technologies’ 12, 16, or 20 dB cable taps. As such the maximum EIRP will be at the first tapped antenna, which will be 12 dB below the maximum signal level of the LinkNet™ (+40 dBm); +28 dBm, or 0.63 Watts EIRP. These antennae are to be installed such that no person can touch the antenna, or approach within 0.2 Meters. Note! If multiple LinkNet™ Modules are used with output combiners, then the composite power output of all Modules transmitting simultaneously must meet this maximum EIRP requirement. Please consult Powerwave Technologies Inc. for assistance as required.
