iii LinkNet LNKA800 RF MODULES ! USER MANUAL DCM000000054 1 . L N K A 8 0 0 M O D U L E S Overview Theory Of Operation A LINKNET AMPLIFIER MODULE is a Broad-Band Digitally Controlled Class-A Amplifier. The most common LINKNET AMPLIFIER 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, an LINKNET AMPLIFIER MODULE is very similar to a regular two-way radio repeater. On Frequency Radio Repeaters 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 AMPLIFIER MODULE systems is that of input to output antenna isolation. This must be carefully engineered for each installation. These Modules are designed for indoor use only and are intended for mounting in a standard EIA 19 inch rack. Modular design of LINKNET AMPLIFIER MODULE circuitry allows for easy servicing, stocking of spares, adaptability and upgrade ability.

info@kaval.com Configuration In line with the versatility of the LinkNetTM Platform, it is possible to re-configure the LNKA800 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 Kaval 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.

USER MANUAL DCM000000054 Power On Self Test (POST) Each system module automatically performs a self-diagnostics when inserted into the system Card-cage. These tests determine that the unit is a) correctly installed in the Card-cage and b) not damaged in transit. All six of the LEDs on the front panel will flash 3 times If the LEDs do NOT flash three times, then remove the module, check the power If the card is OK the LEDs will continue normally. (See Normal Operation) If there is a fault, then the Red Fault LED will remain on. If this occurs, contact source, and re-insert the module, (See Installation Instructions). your KAVAL WIRELESS TECHNOLOGIES Service Representative, (See Warranty / RMA Procedures). 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. Printed: 01.05.08,16:18 Revision Date:5/8/01 9 LinkNet LNKA800 RF MODULES ! USER MANUAL DCM000000054 Normal Operation The LNKA800 Module has six LEDs on the faceplate:
1. OPERATING - Operating normally. 2. STANDBY Under the control of the Control Module, the LNKC1900 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 LEDs will show an operating Module. 3. TRANSMIT No function on these Modules. 4. RECEIVE No function on these Modules. 5. PROGRAM This LED will be 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. 6. FAULT Red LED, If the internal diagnostics for the module detect a problem, then this LED will remain on Printed: 01.05.08,16:18 Revision Date:5/8/01 10 LinkNet LNKA800 RF MODULES !

USER MANUAL DCM000000054 Antenna Installation All Antenna Installation to be performed by Qualified Technical Personnel only. Antenna Installation Instructions and locations below are for the purpose of Note that if multiple LinkNet Modules are used, the Instructions below apply to the composite power output of all Modules when transmitting simultaneously. satisfying FCC RF Exposure Compliance requirements. 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 10 dB. 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 100 Watts maximum. Please consult Kaval Wireless for assistance as required. 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. This is shown in the figure in the Introduction. The Indoor Antennae are simple 1/4 Wavelength (0 dB Gain) types. They are used with KAVAL WIRELESS 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. 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 Kaval Wireless for assistance as required. These Antennae are to be installed such that no person can touch the Antenna, or approach within 0.2 Meters. ANTENNA INSTALLATION WARNING ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED TECHNICAL PERSONNEL ONLY. ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE PURPOSE OF SATISFYING FCC RF EXPOSURE COMPLIANCE REQUIREMENTS, AND ARE NOT OPTIONAL. ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO PERSON CAN TOUCH THE ANTENNA, OR APPROACH CLOSER THAN 10 METERS. ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT NO PERSON CAN TOUCH THE ANTENNAE, OR APPROACH CLOSER THAN 0.2 METERS. Revision Date:5/8/01 12 Printed: 01.05.08,16:18
