LINKnet™ OFR400 RF MODULES ! USER MANUAL DCM000000019 Printed: 00.04.11,13:13 Revision Date:4/11/00 4 Theory Of Operation An OFR, or On Frequency Repeater, is a radio repeater that simultaneously receives and transmits a single narrow band radio channel on exactly the same frequency. The OFR accomplishes its repeater function without store and forward circuitry, or expensive conventional simulcasting techniques. The fact that the same frequency is retransmitted by an OFR means that additional frequency allocations are not required in situations where an existing radio coverage pattern needs to be extended. The most common OFR 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 OFR 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 OFR systems is that of input to output antenna isolation. This must be carefully engineered for each installation. Standard On Frequency Radio Repeaters are designed for indoor use only and are intended for mounting in a standard EIA 19 inch rack. Modular design of OFR circuitry allows for easy servicing, stocking of spares, adaptability and upgrade ability.

USER MANUAL DCM000000019 Printed: 00.04.11,13:13 Revision Date:4/11/00 8 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 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 your KAVAL TELECOM INC. 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.
LINKnet™ OFR400 RF MODULES ! USER MANUAL DCM000000019 Printed: 00.04.11,13:13 Revision Date:4/11/00 9 Normal Operation The OFR400 Module has six LED’s on the faceplate: 1. OPERATING - Under normal operating conditions, this LED will flash GREEN when RF Data is present. 2. STAND BY – Under the control of the Controller Module, the OFR400 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. 3. Transmit – This Green LED will be on when a signal is being transmitted 4. Receive – This Green LED will be on when a signal is being received 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

The Antenna Gain must be no more than 10 dB. The Roof Top Antenna 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 TELECOM INC. 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™ (+37 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. 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. Antenna Installation
